In an ocean ecosystem, which is necessary to begin a food web?

Answers

I believe that phytoplankton is necessary to begin a food web

Answer:

Phytoplankton

Explanation:

Formed by unicellular eukaryote microalgae, phytoplankton is defined as the portion of planktonic organisms capable of photosynthesis, constituting the basis of the food chain in aquatic ecosystems. For this reason, we can say that in an ocean ecosystem, phytoplankton production is necessary to start a food chain.

Phytoplankton are composed of individuals from different taxonomic groups that have some common characteristics: they all have individualized nucleus and complex organelles in their cytoplasm, as well as photosynthetic pigments (chlorophyll a, b, carotenoids). These organisms, predominantly autotrophic, can also ingest particles, being characterized in some cases as myxotrophic.

Why must predators in ecosystems with low npp cover huge ranges to survive?

Answers

NPP is the actual available energy that's produced by primary producers for other organisms to obtain energy from. When a predator lives in a ecosystem that has a low NPP, it means that the predator will have to cover a much wider range in order to have all the needed energy that's produced by those primary producers. If the there was a high NPP the need to search for those primary producers was much diminished as there would be enough energy available close by.

John and sue are expecting a child, but are concerned about a rare autosomal recessive disease that is present in both of their families. in the pedigree below, john is represented as individual iii-11 and sue is represented as individual iii-12. john\'s sister, iii-10, and sue\'s brother, iii-13, both do not show evidence of the disease, but john\'s paternal grandmother and sue\'s maternal grandfather both had the disease. assign the appropriate symbol to each individual in the pedigree.

Answers

Attached is the pedigree. I found the exercise on the internet.

The individuals that are missing a symbol are: II-5, II-6, II-8, III-10, III-11, III-12, III-13.

The individual II-5 would have the half black/half white square. A square because in the introductory text says that it's John's paternal grandmother (I-2) that has the disease. Half black/half white because his mother had the disease so she passed one allele that's necessarily a disease allele, and his father doesn't carry the disease or manifest it which means that from him, John's father (II-5) only received a normal allele.

The individual II-6 would have a question mark in a circle. A circle because she is John's mother once his father is the individual II-5. A question mark because we don't have information as for the manifestation of the disease in her, though we do know that she is either a carrier of the disease or inflicted by the disease because she has a daughter (John's sister) that has the disease meaning that John's sister received two alleles for the disease.

The individual II-8 would have the half black/half white circle. A circle because she is Sue's mother once her father is the individual II-7 (a square). Half black/half white because her father had the disease so he passed one allele that's necessarily a disease allele, and her mother doesn't carry the disease or manifest it which means that from her, Sue's mother (II-8) could only received a normal allele.

The individual III-10 would have a question mark in a circle. A circle because she is John's sister as said in the introductory text. A question mark because we can't affirm whether she is a carrier of one disease allele or does not carry the disease at all. We know by the introductory text that she doesn't have any signs of the disease but she could've have received a disease allele from her father or her mother if her mother is simply a carrier of one disease allele, or would definitely received a disease allele from her mother, and not from her father, if her mother has the disease.

John, the individual III-11 would have a question mark in a square. A square because is John, a male. A question mark because we can't affirm whether he is a carrier of one disease allele or does not carry the disease at all. We gather, by the introductory text, that he doesn't have signs of the disease but he could've have received a disease allele from his father or his mother if his mother is simply a carrier of one disease allele, or would definitely received a disease allele from his mother, and not from his father, if his mother has the disease.

Sue, the individual III-12 would have a question mark in a circle. A circle because is Sue, a female. A question mark because we can't affirm whether she is a carrier of one disease allele or does not carry the disease at all. By the introductory text, we gather that she doesn't have signs of the disease, but she could've have received a disease allele from her mother, once her mother is a carrier of a disease allele, turning her into a carrier as well, or could've received the normal allele from her mother. From her father she only received a normal allele.

The individual III-13 would have a question mark in a square. A square because he is Sue's brother according to the introductory text. A question mark because we can't affirm whether he is a carrier of one disease allele or does not carry the disease at all. We know, by the introductory text, that he doesn't show any signs of the disease, but he could've have received a disease allele from his mother, once his mother is a carrier of a disease allele, turning him into a carrier as well, or could've received the normal allele from his mother. From his father he only received a normal allele.

From this information, John and Sue have a 25% probability (1 in 4) of having a child with the disease (aa), a 50% probability (2 in 4) of having a child who is a carrier (Aa), and a 25% probability (1 in 4) of having a child who is neither affected nor a carrier (AA). This is figured through a Punnett Square analysis of two heterozygous carriers (Aa x Aa).

In this, we are dealing with a pedigree that represents an autosomal recessive disease. Let's first understand the symbols used in a pedigree:

Squares represent males and circles represent females.A horizontal line between a male and a female indicates marriage or mating.Vertical lines connected by a horizontal line indicate siblings.Shaded symbols represent individuals who are affected by the disease.

In order to assign the appropriate symbols to each individual, we need to identify their genotypes. Since the disease is autosomal recessive, it means that the disease allele is represented by 'a', and the normal allele is represented by 'A'. Therefore:

AA (homozygous dominant) means the individual does not have the disease and is not a carrier.Aa (heterozygous) means the individual does not have the disease but is a carrier.aa (homozygous recessive) means the individual has the disease.

Given the information:

John (iii-11) and Sue (iii-12) do not show evidence of the disease but have a family history of it. Therefore, they are likely heterozygous carriers (Aa).John’s sister (iii-10), who does not show evidence of the disease, is likely also Aa, since the disease is present in the family but she herself is unaffected.Sue’s brother (iii-13) also does not show evidence of the disease and is likely Aa for the same reason as John’s sister.John’s paternal grandmother and Sue’s maternal grandfather had the disease, meaning they are aa.

With this knowledge, we can deduce the following genotypes:

iii-11 (John): Aa (heterozygous carrier)iii-12 (Sue): Aa (heterozygous carrier)iii-10 (John’s sister): Aa (heterozygous carrier)iii-13 (Sue’s brother): Aa (heterozygous carrier)John’s paternal grandmother: aa (homozygous recessive)Sue’s maternal grandfather: aa (homozygous recessive)

How does the fast blast dna stain work to make the dna visible to the naked eye?

Answers

DNA fragments stained with Fast Blast DNA stain appear deep blue against a light blue background and are visible to the naked eye

Why were you able to see the dna after adding ethanol? what chemical process led to the visible masses of dna?

Answers

The chemical process is called precipitation.

Usually, a combination of salt and ethanol are added to a solution in order to allow the DNA to precipitate or come out of solution.

Polar molecules are those with uneven distribution of charges in their structure, which gives them partial positive and partial negative parts in their structure. In general, the rule in solubility is "like dissolves like," which means that polar or charged solutes can dissolve in a polar solvent. Ionic and polar solutes which are "attracted" to and dissolve in water are called "hydrophilic" (water-loving), while nonpolar solutes, which do not dissolve in water are called "hydrophobic" (water-fearing or hating).

DNA has a sugar-phosphate backbone in its structure. The phosphate (PO3-) groups of the backbone are negatively charged. Water, being a polar molecule (with the oxygen end being more negatively charged, and the hydrogen ends being more positive), can interact with the negatively-charged phosphate groups of the DNA and allow the DNA to dissolve in water.

When salt (usually sodium acetate) is added, the positive ions of the salt (e.g. Na+ for sodium acetate) interact with the negatively-charged ends of the phosphate groups (PO3-) in the sugar backbone. This "neutralizes" the charges of the negatively-charged phosphate groups. As a result, the amount of water molecules able to interact with the phosphate groups diminishes, and this lessens the solubility of the DNA.

However, because water has a relatively high dielectric constant (index of polarity), it would be fairly difficult for the Na+ ions to interact with the PO3- groups. Adding the ethanol, which has a lower dielectric constant than water, makes it easier for the Na+ ions to come together with the PO3- groups, and shields it charge from the water molecules. This makes the DNA molecules less hydrophilic and less soluble. As a result, the DNA molecules come out of solution (through a process called precipitation).

Answers

"Raw materials which are essential for life are cycled through the Earth's crust"

Answer: b. Fossil fuels are a valuable energy source for the biosphere.

Explanation:

The living organisms are dependent upon the earth crust for their food and resource needs. The earth crust is mined for a variety of inorganic and organic reserves like minerals, fossil fuels like petroleum, gasoline, natural gas and coal. The fossil fuels are non-renewable resources which are produced after million's of years the complete degradation and decomposition of the organic matter of dead animals and plants. This act as source of energy by the living organisms in biosphere.

"which part of the brain controls the autonomic nervous system?"

Answers

Final answer:

The hypothalamus is the key part of the brain that controls the autonomic nervous system, managing involuntary functions and maintaining homeostasis.

Explanation:Which part of the brain controls the autonomic nervous system?

The autonomic nervous system (ANS) manages involuntary functions such as heart rate, blood flow, and digestion. The hypothalamus is the primary structure in the brain that coordinates these functions. The hypothalamus integrates sensory information and cognitive processes to manage the ANS. It sends signals via the medial forebrain bundle and the dorsal longitudinal fasciculus to brain stem and spinal components of the ANS. This integration allows for the control of the lungs, heart, smooth muscle, and glandular functions without our conscious input. It is crucial for maintaining homeostasis in the body through its regulation of the sympathetic and parasympathetic nervous systems, which have often opposing effects to balance the body's internal environment.

What do the properties of waves moving through aquatic environments tell us about the organisms living in those environments?

Answers

Aquatic organisms greatly depend on the abiotic actors of an aquatic environment. Waves moving through the aquatic environment also influence the organisms living there. Depending upon the tidal zones, the organisms varies. Many aquatic organisms grow well in the intertidal zone can live in dry environment for a longer period of time. These organisms are also well adapted to withstand the damages that might be caused by the repeatedly pounding wave actions. Such organisms have tough exoskeleton (strong shell) to protect them from wave damage.
Some coastal plants are firmly attached to the rocks o that these are not torn away by the wave action. These plants have small, tough feather-like leaves.

Using what you've learned, propose some possibilities for how commensal species, in contrast to infectious species, might live with us in peaceful symbiosis. consider commenting on ways the immune system remains refractory to commensals, compared to pathogens. see grading rubric below.

Answers

Commensal bacteria are present in places that are exposed to the external environment (gastrointestinal, respiratory tract, vagina,mouth, skin). There bacteria live constantly with their hosts and only under specific conditions they are able to express pathogenic traits.
The immune system has mechanisms for tolerating these commensal micro-organisms but actively reacts with potentially pathogenic bacteria, inducing the accumulation of regulatory T (Treg) cells.
This is why there is a symbiotic relationship between the host and the microflora

This element has similar chemical properties as oxygen more protons than neon but fewer than argon

Answers

The element is SULPHUR.
Sulphur has similar chemical properties as oxygen because the two of them are in the same group. Sulphur has more protons than neon because, sulphur has 16 protons while neon only has 10. Sulphur has fewer proton than argon because sulphur has 16 protons and argon has 18 protons.

The element described is fluorine (F), with similar chemical properties to oxygen, more protons than neon, and fewer than argon, being highly electronegative and reactive.

The student is asking about an element that has similar chemical properties to oxygen, more protons than neon but fewer than argon. The element in question would be fluorine (F), which has an atomic number of 9. Like oxygen, fluorine is highly electronegative and tends to form negative ions by gaining an electron to complete its valence shell, achieving a stable electron configuration akin to neon. Fluorine has one more proton than neon (Z=10) and is one element prior to neon in the periodic table, making it a member of the halogens, which are known for their high reactivity and tendency to form compounds by gaining electrons. Argon (Ar), with an atomic number of 18, has a complete octet of outer-shell electrons and is a noble gas, chemically inert with rarely forming compounds.

1. Would you expect endangered species to be more frequently generalists or specialists?

Answers

Generalists are species that can thrive in many different kinds of environments and can feed on a varied diet. On the other hand, specialists require specific or special kinds of environments and diets for them to live, reproduce, and thrive. Because of their nature, specialists tend to less likely be able to adapt to changes in their environment. Inability to adapt would eventually lead to their deaths or their inability to reproduce, reducing the population of their species. Thus, endangered species are more frequently specialists.

Is it possible for two alleles to produce four phenotypes?

Answers

Yes the multiple alleles produce more than three phenotypes.

Yes, two alleles can contribute to multiple phenotypes through multiple allele inheritance and dominance hierarchies, allowing for a variety of phenotypic expressions beyond the simple dominant-recessive relationships originally described by Mendel.

It is possible for two alleles to contribute to multiple phenotypes if there are dominance hierarchies among multiple alleles at a single gene locus. This is known as multiple allele inheritance.

When discussing multiple alleles in a population, it is important to note that while an individual organism can only have two alleles for a gene (one from each parent), a population may have many alleles for a single gene. Some alleles might be dominant, others recessive, and some may even show incomplete dominance or co-dominance.

In the case of a gene with four different alleles, these can interact in various ways to produce a spectrum of phenotypes. For example, in rabbits, the coat color is determined by multiple alleles of the c gene. The wild-type allele is dominant to all other alleles, chinchilla is incompletely dominant over the Himalayan and albino alleles, and so forth. Therefore, the phenotype of progeny resulting from crosses between any pair of the four mutants will depend on the dominance hierarchy of these alleles.

To answer the original question, two alleles can influence more than two phenotypes if there are multiple alleles at the population level and varying dominance relationships among those alleles.

What does ATP do for cells

Answers

ATP, or adenosine triphosphate, acts as the 'energy currency' of the cell, releasing energy when its terminal phosphate group is removed. This energy powers cellular processes, including muscle contraction and active transport, such as the sodium-potassium pump in cell membranes.

ATP, or adenosine triphosphate, is often described as the "energy currency" of the cell. It plays a critical role in storing and providing energy for various cellular functions. ATP molecules hold smaller amounts of energy, which is released just in the right amount for work within a cell. The release of energy occurs when ATP is broken down, usually by the removal of its terminal phosphate group, and this energy is employed in several ways.

For instance, muscle cell proteins utilize the energy for contraction by pulling each other, and this is made possible when bonds in ATP break open, releasing energy. ATP is also essential in processes such as photosynthesis, where it provides the energy to build glucose. Similarly, ATP is critical in cellular mechanisms like the active transport work of the sodium-potassium pump in cell membranes, where it alters the structure of the pump's integral protein to move ions against their electrochemical gradients.

Overall, ATP is indispensable for the cell, as it safely stores energy and releases it as needed to perform various cellular tasks, acting much like a rechargeable battery to power the cell's activities.
