An electromanget converts electrical enegry into

Answer:

D) mimicry

Explanation:

If we have two different species of insects that live in separate geographic areas but they display the same characteristic black and red stripes it can mean a lot, as there are numerous factors that can contribute to it. For starters, the two species might have a common ancestor that was exhibiting those same or similar black and red stripes, and if they did their job properly, there's every chance that both species would have kept them. It can be simply an aposematic coloration that developed in the same manner through convergent evolution as a protection or warning from the predators. We can not say that it is an example of mimicry, as the two species live in different geographic areas, thus they are not in contact with each other, thus they can not replicate the colors and behavior from the other species.

When two species of insects from different geographic areas display characteristic black and red stripes, the phenomenon that is unlikely to be related to this occurrence is C) common ancestry.

The similar coloration is more likely due to aposematic coloration, which is a type of warning coloration used by species to signal danger or a bad taste to predators. This adaptation can also be an example of convergent evolution, where unrelated species develop similar traits independently because they adapt to similar environments or challenges. Additionally, mimicry can explain the phenomenon, where a harmless species imitates the warning coloration of a harmful species. This shared pattern may also serve as an effective defense against predators.

Mimicry and camouflage are aposematic defense mechanisms that can provide a survival advantage to these insects by deterring predators. In Batesian mimicry, for example, a non-toxic species imitates the coloration of a toxic species to benefit from the same avoidance behavior by predators.

Answer:

1. During DNA replication, an open section of DNA, in which a DNA polymerase can replicate DNA, is called a replication fork.

2. After replication is complete, the new DNAs, called daughter DNAs, are identical to each other.

3. The enzyme that can replicate DNA is called DNA polymerase.

4. Okazaki fragmentsare the short sections of DNA that are synthesized on the lagging strand of the replicating DNA.

5. The new DNA strand that grows continuously in the 5' to 3' direction is called the leading strand.

Explanation:

DNA replication is a process  that occurs during the interphase (S phase) of the cell cycle and in which DNA is replicated. DNA replication is semiconservative which means that each strand in the double helix (leading strand and lagging strand) acts as a template for synthesis of a new, complementary strand that will become daughter DNA.

DNA polymerase is the main enzyme of the DNA synthesis: it requires primer (short sequence of DNA) for the initiation and it performs its function only in one direction 5'-3'. Other enzymes involved in DNA replication are DNA primase, DNA helicase, DNA ligase, and topoisomerase.

During DNA replication, a replication fork forms where DNA polymerase can replicate DNA. After replication, the new identical DNA strands are called daughter DNA. The short sections of DNA synthesized on the lagging strand are known as Okazaki fragments, while the continuously growing DNA strand is the leading strand.

Answer:

The correct labels are :

Label A  prophase

Label B metaphase

Label C anaphase

label D telophase

Explanation:

Mitosis, a method of cell division which complete in four different phases. These phases are prophase, metaphase, anaphase and telophase. In the given question the correct labels are: A-prophase; B-metaphase; C-anaphase and D-telophase. Mitotic division is begins with prophase in which chromatin threads condense and called chromosomes. During metaphase all the chromosomes get arranged in the central plane. In the anaphase, the sister chromatids of each chromosome gets separated and move to the opposite pole. In the telophase the spindle breaks from the chromatids and begins to disappear. The nuclear membrane starts to form around each of the daughter chromosomes.

Answer:

a: prophase

b: metaphase

c: anaphase

d: telophase

Answer: B) meiosis :))

Answer:

B) meiosis

Explanation:

Meiosis is a process of cell division in which cells have their chromosome numbers halved and form distinct units due to crossing-over. Through this process plant spores and gametes are formed in animals - eggs and sperm.

As we all know, the egg is the female gamete and the sperm the male. Both the spumatozoa and the egg have half the alleles of each parent that will be passed on to their children.

The sperm has a "pouch" full of digestive enzymes called the acrosome, which helps in fertilization by digesting the egg wall, allowing its entry. When the sperm enters the egg it delivers its DNA, sensing the entry of this genetic material, this mucus that surrounds the once gelatinous egg, stiffens, preventing the entry of other sperm. This is why the egg is fertilized by only one sperm.

I think the cell’s can become cancer cells but I’m sorry if it isn’t correct...

Answer:

Option D

Explanation:

Mutation causes cancer which is in general acquired i.e developing due to the habits of an individual. Some common factors that lead to acquired mutation are – smoking, exposure to ultraviolet radiation, viruses injection etc. Such factor interrupts with the genetic code of the normal cell and lead to uncontrolled division of cell thereby causing cell mas or cell clot which eventually becomes tumor and cancer.  

Hence, option D is correct

Answer:

B) aposematic coloration

Explanation:

The species constantly compete between each other, some because they occupy the same niche int he food chain, others even though they are in different niches tend to destroy each other, and some just avoid each other and partition the resources. This often results in partitioning of the resources between different species, when usually they are active in different parts of the day and avoid each other. Also, it is common that some of the species is more competitive, so that will result in a decline of the other species, or if the species are on the same level of competitiveness, then usually both species have declines in numbers to some optimal level. The aposematic coloration though is not part of the competition between the species. It is a type of coloration that warns the other species that the species that possesses it is either not good for eating, or it has a weapon that can harm them, thus they should avoid it and leave it alone.

D. Microscopic organisms break down the apple and release its material into the soil and air.

Explanation:

Without microscopic organisms today, everything that has died or fallen will still remain on the ground. Fungi, bacteria, and etc. play an essential role in the Earth's ecosystem by breaking down organic material.

An apple falls off a tree onto the ground. The statement best describes reason that makes up the apple is  that the microscopic organisms break down the apple and release its material into the soil and air. The correct option is D.

The organisms very small in size, that are not be seen by the eyes. They can be seen by using the microscopes.

The apple fall off when it has no bond with the tree. The micro-organism starts decomposing the apple from the top notch. As, the bond with the tree branch loosens, the apples fall off a tree onto the ground.

Thus, the statement best describes reason that makes up the apple is  that the microscopic organisms break down the apple and release its material into the soil and air. The correct option is D.

Answer:

D) two species of rattlesnake that both rattle their tails

Explanation:

The Mullerian mimicry can simply be described as a common feature of two or more different species that can be harmful and dangerous in order to fend of predators. In this case we have the two species of rattlesnake which are using the same method to fend of any predators from, by rattling their tails. This is very useful as a defense mechanism because the species that can cause harm to them only need to encounter one of the species and then be wary of both and avoid them both, as both species use the same tactic for defense or warning, thus the chances are reducing even more that an animal, especially a young and inexperienced one, will mess with them or attack them.

Müllerian mimicry refers to when multiple harmful or unappealing species share the same warning coloration to deter predators. An example would be two species of unpalatable butterflies that have the same color pattern. This stands in contrast to Emsleyan/Mertensian mimicry, where a dangerous prey mimics a less harmful one.

In Müllerian mimicry, multiple species that are unappealing or harmful to predators share the same warning coloration to benefit from combined deterrence. All the mimicking species actually possess defenses. An example of this from your list would be two species of unpalatable butterflies that share the same color pattern. It's a mutual reinforcement of the warning signal, making it more effective in averting predators.

Emsleyan/Mertensian mimicry, on the other hand, is where a more dangerous species mimics a less dangerous but noxious one, like a venomous coral snake mimicking a non-venomous milk snake. This is different from Müllerian mimicry, as the mimic is more harmful than the model it is imitating.

Understanding these mimics involves understanding animal behavior and predator-prey interactions, providing insight into the complex dynamics of ecosystems.

Mutualism is a type of ecological interaction between two species in which both have benefits (double positive interaction). Mutualism also can be considered as a type of symbiosis-two species that live together. Termites and protozoans are a great example of correlation between two species that work together and provide positive effect one to another. Termites provide food to protozoans, while protozoans provide energy to the termites.

Answer:

Proten W

Explanation:

SDS-PAGE gel is a method used for the separation of proteins in which proteins are separated based on their length (smaller proteins move faster through the gel, due to less resistance).

When treated with proteolytic enzymes, proteins are cut and become short fragment. This means that the fragments formed after the use of proteolytic enzymes, will move faster and thus, migrate a longer distance. Proteolytic enzymes in Set 2 cells will act only on plasma membrane proteins (because they cannot penetrate), while in Set 2 they will act on both, plasma membrane and interior proteins. Control group will have only the large fragments (not treated with enzyme).

Protein W travels the same distance on a gel of proteins from Set 1 and Set 2, but different than control group. It means that the proteolytic enzyme worked the same on Set 1 and Set 2.

Protein Y is exposed only on the exterior of the cell because it migrates further on the SDS-PAGE gel after treatment with a proteolytic enzyme that cannot penetrate the cell membrane.

Based on the experimental results, Protein Y is the one exposed only on the exterior of the cell. Its migration pattern on SDS-PAGE gels is key to this conclusion. For the untreated control group, Protein Y migrates at a certain distance indicative of a larger size/mass. When Protein Y is extracted from Set 1 cells (treated with the large proteolytic enzyme that cannot penetrate the cell membrane), it migrates a longer distance on the gel, suggesting a smaller size due to cleavage by the enzyme on the cell surface. In Set 2 cells (made permeable before enzyme treatment), Protein Y moves even further, indicating further cleavage of both extracellular and possibly intracellular portions. Protein Y has parts accessible to the enzyme when the membrane is intact, indicating those parts are extracellular.

Answer:

B) as one travels north from the South Pole

Explanation:

The South Pole is one of the most inhospitable places for living on the planet, be it for humans, animals, or plants. The temperatures are always far below zero, there are ice sheets that have a depth of several kilometers, and very strong freezing winds. As we move north of the South Pole, practically toward the lower latitudes and the Equator, the living conditions gradually improve more and more. The climate is much more pleasant, there's different types of soil, precipitation and that results in gradual increase in the number of species that live in those areas. As we will be getting closer and closer to the Equator, the abundance of species will skyrocket, with millions of different species living in that part of the planet because it is always warm and there's large amounts of water and precipitation, providing excellent conditions for enormous amount of species to prosper.

Answer:

D) dominant and keystone

Explanation:

The elephants are animals that can be classified as both dominant species and as keystone species. A dominant species is a species that is in relatively small numbers, but it dominates the community. We can easily see this with the elephants, as they are not many in number, but they are the largest and strongest animals in their community, and no other animal can dominate over them. A keystone species is a species that has a key role in the functioning of the community, its structure, well being, and even existence. Again, we can easily see this in the elephants as the savanna is completely dependent on them. If the elephants are not present with their activities, the vast grasslands will soon turn into forests or mixture of trees and shrubs, thus the community will change dramatically. That will lead to the dying out of most of the species that live int he savanna as they are not well adapted to survive in a community with dense tropical vegetation.

Answer:

1/64

Explanation:

This is a typical trihybrid cross involving three genes coding for plumage color, shank type and comb shape in leghorn chicken. White plumage (W), feathered shank (F), and pea comb (P) are all dominant over colored plumage (w), clean shank (f) and single comb (p) respectively.

A cross between an all homozygous dominant chicken (WWFFPP) and an all homozygous recessive chicken (wwffpp) will result in an F1 that exhibits all the dominant traits but heterozygous (WwFfPp). If the three genes assort independently, 8 types of gametes will be produced by this F1 offsprings: WFP, WFp, WfP, Wfp, wFP, wFp, wfP, wfp.

If the F1 offsprings are self-crossed, we use this gametes in a punnet square to obtain 64 possible F2 offsprings in a phenotypic ratio 27:9:9:9:3:3:3:1. This ratio is the phenotypic ratio of a trihybrid cross.

According to the question which says that what proportion of the F2 offsprings will produce all the dominant traits (white, feathered, pea) if crossed with an homozygous recessive chicken (wwffpp). This means that to produce only offsprings with an all dominant trait, the parent that combines with the homozygous recessive (wwffpp) must be homozygous dominant (WWFFPP) for all three traits.

In the ratio 27:9:9:9:3:3:3:1, the "27" represents the offsprings that have all dominant traits, but only one (1) of these 27 possesses a homozygous dominant genotype for all three traits (WWFFPP), which also means only 1 out of the possible 64 offsprings possesses an homozygous dominant genotype for all three traits.

Hence, the proportion that will produce only white, feathered pea-combed chicken (heterozygous) if mated to colored, clean, single-combed birds is 1/64.

Answer:

c. autotrophs and animals are heterotrophs

Explanation:

There's many differences between the plants and the animals, be it their physical appearance, way of live, how do they function, their requirements for survival. One of the major differences between the plants and the animals is that the plants are autrotrophs, while the animals are heterotrophs. The autrophs are the organisms that are able to produce their own food, thus they are producers, meaning that they do not need nutrition from other organic sources. The heterotrophs on the other side are the organisms that are not able to produce food for themselves, but instead they get their food through consuming of other living organisms, making them primary, secondary, and tertiary consumers.

Answer:

Body organs cannot move freely but are embedded in solid mesosphere tissue. 2. It is more difficult for materials to move from the gut to the body wall. A solution to both problems is to have some sort of body cavity, called a compel, in which the body organs lie bathed in body fluid.

Explanation:

This is the answer and if you need more we can help

The coelom, a fluid-filled body cavity, exhibits two notable advantages: it provides protection and shock absorption for internal organs, and it supports organ growth and mobility, contributing to better organ function and animal motility.

The evolution of body cavities in multicellular organisms, specifically coelom formation, brought about significant functional advantages. The coelom is a fluid-filled body cavity that exists between the digestive tract and the body wall in triploblastic animals (those with three germ layers, specifically mesoderm). Among its many benefits, two advantages stand out:

Natural selection does not solely allow better alleles to be passed on. It acts on individual fitness that encompasses a range of alleles, and linkage disequilibrium can cause the inheritance of linked alleles irrespective of their individual benefit.

I disagree with the statement that natural selection allows only the better alleles to be passed onto the next generation for two main reasons. First, natural selection acts on the level of the individual, not the allele. Good alleles might be lost if the individual carrying them has many disadvantageous alleles, impacting their overall fitness negatively. Second, some alleles are closely linked in the genome, leading to linkage disequilibrium, which means that these alleles can be inherited together regardless of whether they are beneficial or not.

Answer:

The law of segregation lets us predict how a single feature associated with a single gene is inherited. In some cases, though, we might want to predict the inheritance of two characteristics associated with two different genes. How can we do this? [Refresher on the law of segregation]

To make an accurate prediction, we need to know whether the two genes are inherited independently or not. That is, we need to know whether they "ignore" one another when they're sorted into gametes, or whether they "stick together" and get inherited as a unit.

When Gregor Mendel asked this question, he found that different genes were inherited independently of one another, following what's called the law of independent assortment. In this article, we'll take a closer look at the law of independent assortment and how it is used to make predictions. We'll also see when and why the law of independent assortment does (or doesn't!) hold true.

Note: If you are not yet familiar with how individual genes are inherited, you may want to check out the article on the law of segregation or the introduction to heredity video before you dive into this article.

Answer:

E) a ''walking stick'' insect that resembles a twig

Explanation:

The cryptic coloration is a type of coloration that helps an organism to blend in its environment. With other words, it is a camouflage. This type of coloration has been developed by organisms that are prey, but also by organisms that are predators. The organisms that are prey use this type of coloration in order to hide themselves from the predators, to be as unnoticeable as possible, thus to avoid being attacked. The predators on the other hand, use this type of coloration in order to blend in with the surroundings so that they can come closer to their prey and attack it without being noticed. We can easily say that this type of coloration works in both of the ways. The ''walking stick'' insect for example, resembles a twig, thus it has a perfect camouflage to not be spotted and attacked. On the other hand we have the tiger with its stripes, which is an unusual coloration for a cat, uses its stripes to break up the outline of its body, thus making it either unnoticeable or it confuses the prey.

The example of cryptic coloration is a "walking stick" insect that resembles a twig.

The correct example of cryptic coloration is option E) a "walking stick" insect that resembles a twig. Cryptic coloration or camouflage is a defense mechanism for animals that allows them to blend in with their environment, making it difficult for predators to spot them.
