Which statement is most supportive of the claim that genetic diversity is an advantage of sexual reproduction?

Genetic variation from sexual reproduction ensures that at least some individuals will have advantageous traits that help them survive.

Asexual reproduction results in the same genes being copied, which means the same vulnerabilities in the population.*******

Sexual reproduction creates genetic diversity, which results in a wide range of appearances in a population.




Lack of genetic diversity from asexual reproduction results in a diminished ability to survive changes to the environment.


What is the most likely explanation for a child exhibiting a heritable trait that neither parent exhibits?

The trait was passed on by a different biological parent, and one of the child's parents is not biologically related.

The trait was inherited from a more distant relative, like a great-grandparent.




The parents carried a second trait that masked the trait of interest.

The trait is recessive, so both parents carry it, and the child inherited each recessive allele.**********

Which statement has exceptions?

Sexual reproduction requires two parents, whereas asexual reproduction requires only one parent.

Sexual reproduction produces genetic variation, but asexual reproduction does not.

Sexual reproduction is more complex, while asexual reproduction is a simpler process.

Sexual reproduction involves parental care, while asexual reproduction does not.******

Assume a bacterial cell failed to replicate its DNA before it reproduced two daughter cells. The reproduction would result in

neither cell containing DNA.

both cells containing DNA.

one cell with DNA and one cell without DNA.*******

one cell with DNA and one cell with two sets of DNA.

Hydras are animals related to coral and jellyfish. Hydras can reproduce sexually or asexually. Why would hydras avoid reproducing asexually when conditions are difficult?

The lack of genetic diversity could mean that all of the hydras die, depending on the situation. ******

The high genetic diversity could mean that all of the hydras die, depending on the situation.

Reproducing more rapidly would be a good way to take advantage of plentiful resources.

Reproducing more slowly would be a good way to take advantage of plentiful resources.

Answer 1
Answer:

Final answer:

Sexual reproduction creates genetic diversity, allowing some individuals to have advantageous traits. Inheriting a trait that neither parent exhibits suggests it is recessive and both parents carry it. Hydras avoid asexual reproduction when conditions are difficult to prevent a lack of genetic diversity.

Explanation:

The statement that is most supportive of the claim that genetic diversity is an advantage of sexual reproduction is: Genetic variation from sexual reproduction ensures that at least some individuals will have advantageous traits that help them survive. Sexual reproduction creates unique combinations of genetic material through the process of fertilization, resulting in offspring with diverse traits. This genetic diversity increases the likelihood of individuals having advantageous traits that can help them adapt and survive in changing environments.

In the case of a child exhibiting a heritable trait that neither parent exhibits, the most likely explanation is that the trait is recessive and both parents carry it. This means that the child inherited two copies of the recessive allele, one from each parent, which is necessary for the trait to be expressed.

Hydras, despite being capable of reproducing asexually, would avoid doing so when conditions are difficult because asexual reproduction does not create genetic diversity. Without genetic diversity, all hydras in the population would have the same traits, making them vulnerable to changes in the environment.

Compare the behavior of an endotherm and an ectotherm on a hot summer day. How does each organism respond to changes in the environment?

Answers

Endotherms generate most of the heat they need internally. When it's hot outside, they decrease metabolic heat production to keep their body temperature constant. Because of this, the internal body temperature of an endotherm is more or less independent of the temperature of the environment. 
Contrarily, Ectotherms' body temperature primarily depends on external heat sources. That is, ectotherm body temperature rises and falls along with the temperature of the surrounding environment. So if it is hot outside their body temperature rises as well. 

Answer:

sample response: Endotherms are able to maintain a constant body temperature. An endotherm may respond to a hot summer day by sweating or panting. The body temperature of an ectotherm, on the other hand, changes with its surroundings. In order to stay cool, an ectotherm must move somewhere cooler like the shade of a plant or rock or seek cool water to lay in

Where do most organisms that live in water get oxygen from? Give a word, not a formula.

Answers

The organism that live in water get oxygen from the oxygen that is dissolved in water.

What is oxygen?

Oxygen is a gas, that is present 18% in the environment. The oxygen is an important for living beings because all are activities of our body is run by oxygen.

The water also contain oxygen in the dissolved form, which is used by the water organism.

Thus, the oxygen that is dissolved in water.
