Answer:
size of the volcanos cone
Explanation:
The size of volcano's cone does not affect how explosively or quietly a volcano erupts.
What is a volcano?.A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. Volcanoes are closely associated with plate tectonic activity. Most volcanoes, such as those of Japan and Iceland, occur on the margins of the enormous solid rocky plates that make up Earth’s surface.

A. Chains of DNA codons and RNA anti codons form.
B. Specific codons pair with specific anti codons.
C. DNA strands form a backbone of sugar rings and phosphate groups.
D. Peptides bond to nucleic acid molecules.
Answer:
B. Specific codons pair with specific anti codons.
Explanation:
The nucleotide sequence of mRNA serves as a template for protein synthesis. During the process of protein synthesis, the mRNA nucleotide sequence is read in the form of triplet codons. The tRNA with the complementary anticodon sequence joins the mRNA.
There is base pairing between codon of mRNA and its complementary anticodon of tRNA followed by the formation of a peptide bond between existing amino acid on the ribosome and incoming amino acid carried by tRNA.

how can mutation in a gene lead to a new trait in an organism ?
Answer: D. The mutated gene codes for a protein that causes a new trait
Explanation:
A mutation is a change in the DNA sequence that can occur from multiple causes. For example, by errors during replication or by the action of mutagens such as UV radiation, among others. When a mutation occurs, if not repaired, it can lead to the production of a different protein. This is because genes code for amino acids, which bonded together form proteins. A change in a DNA gene base can lead to code for a different amino acid (or even adding a new one or causing another to be lost). This alteration can lead to the synthesis of another protein involved in the expression of a trait, and giving rise to a different characteristic, which can be beneficial or harmful.
Illegal fishing is thought to account for what percent of fish caught?
A. 10-20
B. 15-40
C. 20-50
D. 50-70
Thank you!
Illegal fishing accounts for a substantial portion of global fish catches, likely falling within the range of 15-40% based on studies and reports on under-reporting and the proportion of illegally caught seafood entering the United States.
Illegal fishing is a significant problem that affects marine ecosystems and economies around the world. According to research, the percentage of fish caught through illegal, unreported, and undocumented (IUU) fishing is substantial, contributing to over-exploitation and depletion of fish stocks. Considering the report by Agnew et al. in 2009 and the data on the under-reporting of global marine fish catches, it is reasonable to deduce that the percentage of fish caught through illegal means could be on the higher end of the provided options.
Additionally, taking into account that 25-30% of wild-caught seafood imported into the United States is illegally caught, as stated by Pramod et al. in 2014, and the significant under-reporting by as much as 50%, the range of illegal catch is likely considerable. Hence, the answer to the question of what percent of fish caught are due to illegal fishing is option B. 15-40%.

Which of these definitions have been paired with the correct type of cell?
Different types of cells in the human body are specialized for specific functions, such as B cells and T cells in the immune system, and natural killer cells targeting virus-infected or cancerous cells.
The question pertains to the functions of different types of cells in the human body. For example, B cells and T cells are types of lymphocytes which play crucial roles in the immune system. B cells are responsible for producing antibodies that bind to antigens and neutralize or mark them for destruction. T cells can be subdivided into helper T cells that aid in immune response coordination and cytotoxic T cells that destroy virus-infected cells and cancer cells.
Natural killer cells are also part of the immune system, and they specialize in recognizing and attacking cells that are infected with viruses or have become cancerous, without the need for prior exposure to the pathogen.
In the case of cell division, the process could be either mitosis or meiosis, depending on whether the context is growth and repair or sexual reproduction, respectively.
Which statement accurately describes reproduction in animals
All animals can reproduce asexually, and some can reproduce sexually
All animals can reproduce sexually, and some can reproduce asexually
Animals only reproduce sexually
Animals only reproduce asexually.
Answer:
B
Explanation:
it just is trusttttttt
Animals can use both sexual as well asexual means for their reproduction. Some animals reproduce asexually through budding while others can reproduce through both sexual as well as asexual modes. Higher animals reproduce through the sexual mode of reproduction. So the correct answer is Option B.
Which animals reproduce asexually?Oligochaetes, planarians, sea stars, starfish, sharks, Crayfish, wasps, snakes like pythons, etc. are some of the animals that reproduce asexually. In the asexual mode of reproduction fusion of gametes does not occur and there is no change in the number of chromosomes of an individual. The same set of genes is passed on from the parent to the offspring and the newly formed offspring is an identical copy of its parent.
Some animals show an alteration between the sexual and asexual modes of reproduction. This is known as heterogamy. Examples of heterogamy include insects and rotifer.

A scientist discovers a new body between the orbit of Neptune and the Kuiper Belt. The object is round and travels in an orbit around Neptune with other space objects. The scientist claims that she has found a new dwarf planet. Where is the scientist’s error?
The error is that an object orbiting Neptune would not be classified as a dwarf planet because it does not orbit the Sun directly, which is a requirement for dwarf planet status.
Explanation:The scientist's error lies in identifying an object that orbits around Neptune as a dwarf planet. By definition, a dwarf planet must directly orbit the Sun, not another planet. According to the International Astronomical Union (IAU), a dwarf planet must satisfy certain criteria, including orbiting the Sun and having sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a near-spherical shape. However, a key feature is that while a dwarf planet must have cleared the neighbourhood around its orbit, an object that is gravitationally dominanted by and in orbital resonance with a planet, as described in the scenario, would likely be considered a moon or satellite of that planet rather than a dwarf planet. The Kuiper Belt is a region beyond Neptune that includes trans-Neptunian objects (TNOs) and is replete with potential dwarf planets, like Pluto and Eris, which are in direct orbit around the Sun and not tethered to another planet's orbit.

In humans, freckles (F) on the skin are dominant to no freckles (f). If two parents are heterozygous for the trait, which statement below best describes their chances of having a child with no freckles?
a
It would be extremely rare for the freckled parents to have a child without freckles because freckles are dominant.
b
The parents will most likely have three children with freckles before having a child without freckles.
c
Every time they reproduce, the parents have a one in four chance of having a child without freckles.
d
If the parents already have three children with freckles, then they are more likely to have a child without freckles.
Answer:
It might be C but sorry if I'm wrong
Two heterozygous parents for the dominant freckle trait (Ff) have a one in four chance of having a child with no freckles (ff) using a Punnett square to determine the probabilities.
Explanation:When considering whether two heterozygous parents can have a child with no freckles, we utilize a Punnett square to determine the possible genetic outcomes. Since freckles (F) are dominant over no freckles (f), a heterozygous individual will have one of each allele (Ff). When these parents have children, each parent has a 50% chance of passing on either the F or f allele.
Using a Punnett square to illustrate this, we would see that there are four possible genetic combinations for their child:
FF - Child with frecklesFf - Child with freckles (heterozygous like the parents)fF - Child with freckles (heterozygous like the parents)ff - Child with no frecklesThus, the correct answer is that every time they reproduce, the parents have a one in four chance of having a child without freckles (option c). This is because the chance for each genotype (FF, Ff, fF, or ff) is equal when both parents are heterozygous (Ff).

HELP ASAP!!!!Question 44 is an open-response question. Wild red 6 poin
wolves were once common in the southeastern United
States. As this area became more developed, the number
of wild red wolves was drastically reduced to about 20
individuals by 1967. These remaining wolves were
captured and bred. In 1987, some captive-born red wolves
were released into an area of North Carolina. Today, there
are more than 50 wild red wolves living in North Carolina.
a. Identify two ways development in the southeastern
United States most likely contributed to the decline of the
red wolf population. Explain each of your answers. b.
Compare the red wolf's genetic diversity before the
southeastern United States became more developed to the
red wolf's genetic diversity in 1967. Explain your answer. c.
Describe one other action, besides capturing and breeding,
that could increase the number of red wolves in the
southeastern United States. Explain how this action could
increase the number of red wolves.
a. The development of the southeastern part of the United States affected many species of animals, including the red wolves. The red wolves were seen as a species that is not useful and not wanted, and on top of that dangerous. Apart from the fact that the development led to destruction of the habitat of the wolves, so lot of them died out because of loss of habitat, the hunting played an even bigger role. As there were more and more people, and the encounters were becoming more often, and the wolves also had less food and started to attack the domestic animals, the hunters got activated and they almost killed the wolves to extinction, with only 20 individuals left.
b. Before the development of the southeastern apart of the United States, the red wolves were in relatively large number. This also meant that the genetic diversity was much greater among the red wolf population, resulting in healthy, stable, and strong population of this predator. When the situation came that only 20 individuals were left, then the genetic diversity shrinking to a very low level. Those 20 wolves did not had any other choice then to breed between each other, so in only couple of generations the genetic diversity become extremely low. That is very dangerous for a population, as if some of the individuals have some bad mutation or disease carrying with them, they can affect all the rest and the population may die out easily.
c. Apart from the capturing and breeding of the red wolves, the other method to increase their population is to reintroduce them into the areas where they once lived, under condition that it is a protected area. By reintroducing enough individuals so that the population can reproduce in a healthy manner, the red wolves population can easily and quickly reestablish itself in a natural manner, also contributing to restoring the natural order in their former habitat.
