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?

To determine the correct answer to the question "Which statement is most supportive of the claim that genetic diversity is an advantage of sexual reproduction?", we need to evaluate each option and find the one that best supports the claim.
Option 1: "Genetic variation from sexual reproduction ensures that at least some individuals will have advantageous traits that help them survive."
This statement directly supports the claim because genetic diversity resulting from sexual reproduction allows for the emergence of advantageous traits that can enhance survival.
Option 2: "Asexual reproduction results in the same genes being copied, which means the same vulnerabilities in the population."
This statement actually supports the opposite of the claim. Asexual reproduction leads to limited genetic diversity, which can make a population more susceptible to vulnerabilities.
Option 3: "Sexual reproduction creates genetic diversity, which results in a wide range of appearances in a population."
This statement emphasizes the creation of genetic diversity thual reproduction, but it does not explicitly address the advantage of genetic diversity.
Option 4: "Lack of genetic diversity from asexual reproduction results in a diminished ability to survive changes to the environment."
This statement again highlights the disadvantage of limited genetic diversity resulting from asexual reproduction, but it does not directly support the claim of genetic diversity being advantageous in sexual reproduction.
Therefore, the most supportive statement is Option 1: "Genetic variation from sexual reproduction ensures that at least some individuals will have advantageous traits that help them survive."
To determine the correct answer to the question "What is the most likely explanation for a child exhibiting a heritable trait that neither parent exhibits?", we need to analyze each option and select the one that provides a valid explanation.
Option 1: "The trait was passed on by a different biological parent, and one of the child's parents is not biologically related."
This option suggests that the child might have inherited the trait from a biological parent who is not one of the child's actual parents. However, this possibility is not stated or implied in the question.
Option 2: "The trait was inherited from a more distant relative, like a great-grandparent."
This option suggests that the trait might have been inherited from a more distant relative. While this scenario is possible, it is not stated or implied in the question.
Option 3: "The parents carried a second trait that masked the trait of interest."
This option suggests that both parents possess another trait that conceals the trait of interest in the child. This possibility aligns with the concept of dominant and recessive traits.
Option 4: "The trait is recessive, so both parents carry it, and the child inherited each recessive allele."
This option suggests that the trait of interest is recessive, and both parents carry it, leading to the child inheriting two recessive alleles. This scenario explains why neither parent exhibits the trait but the child does.
Therefore, the most likely explanation is Option 4: "The trait is recessive, so both parents carry it, and the child inherited each recessive allele."
To determine the correct answer to the question "Which statement has exceptions?", we need to assess each option and identify the one that contains contradictions or instances where the statement does not hold true.
Option 1: "Sexual reproduction requires two parents, whereas asexual reproduction requires only one parent."
This statement is generally true, as sexual reproduction involves the fusion of genetic material from two parents, while asexual reproduction occurs from a single parent. There are no exceptions mentioned in this statement.
Option 2: "Sexual reproduction produces genetic variation, but asexual reproduction does not."
This statement is also true, as sexual reproduction introduces genetic diversity through the recombination and shuffling of genes, while asexual reproduction produces genetically identical offspring. There are no exceptions stated in this statement.
Option 3: "Sexual reproduction is more complex, while asexual reproduction is a simpler process."
This statement generally holds true, as sexual reproduction involves complex processes such as meiosis and fertilization, while asexual reproduction can be a simpler process like binary fission or budding. There are no exceptions mentioned in this statement.
Option 4: "Sexual reproduction involves parental care, while asexual reproduction does not."
This statement appears to have exceptions because certain instances of asexual reproduction, such as in some reptiles, insects, and plants, can involve some form of parental care. However, the statement does not explicitly mention these exceptions.
Therefore, the statement with exceptions is Option 4: "Sexual reproduction involves parental care, while asexual reproduction does not."
To determine the result of a bacterial cell failing to replicate its DNA before reproducing two daughter cells, we need to assess each option and select the one that accurately describes the outcome.
Option 1: "Neither cell containing DNA."
This option suggests that both daughter cells would not contain any DNA. However, DNA replication is a crucial step in cell reproduction, so it is unlikely for both daughter cells to lack DNA.
Option 2: "Both cells containing DNA."
This option suggests that both daughter cells would contain DNA. DNA replication typically precedes cell division, ensuring that each daughter cell receives a copy of the genetic material.
Option 3: "One cell with DNA and one cell without DNA."
This option is the most accurate description of the outcome. In the scenario presented, if the bacterial cell fails to replicate its DNA before reproducing, one daughter cell would likely contain DNA, while the other daughter cell would lack DNA.
Option 4: "One cell with DNA and one cell with two sets of DNA."
This option does not align with the scenario given. If the bacterial cell fails to replicate its DNA, it would not result in one daughter cell having double the amount of DNA.
Therefore, the most accurate outcome is Option 3: "One cell with DNA and one cell without DNA."
To determine the effect of subsequent generations from a parent bacterial cell in the presence of the antibiotic penicillin, we need to evaluate each option and select the one that accurately describes the relationship between the generations and penicillin.
Option 1: "Resistant to penicillin."
This option suggests that subsequent generations from the parent bacterial cell would be resistant to penicillin. This outcome aligns with natural selection where organisms with advantageous traits survive and reproduce.
Option 2: "Killed by penicillin."
This option suggests that subsequent generations from the parent bacterial cell would be killed by penicillin. This outcome would not be expected if the parent bacterial cell can survive in the presence of penicillin.
Option 3: "Dependent on penicillin."
This option suggests that subsequent generations from the parent bacterial cell would be dependent on penicillin. This scenario is unlikely as dependency on an antibiotic would not confer an advantage in terms of survival or reproduction.
Option 4: "Vulnerable to penicillin."
This option suggests that subsequent generations from the parent bacterial cell would be vulnerable to penicillin. This outcome conflicts with the fact that the parent bacterial cell can survive in the presence of penicillin.
Therefore, the correct answer is Option 1: "Resistant to penicillin."
To understand why hydras would avoid reproducing asexually when conditions are difficult, we need to evaluate each option and select the one that provides the most reasonable explanation.
Option 1: "The lack of genetic diversity could mean that all of the hydras die, depending on the situation."
This option provides a logical explanation. Asexual reproduction results in limited genetic diversity, so if all hydras share the same genetic make-up, they could all be susceptible to the same environmental conditions.
Option 2: "The high genetic diversity could mean that all of the hydras die, depending on the situation."
This option contradicts the concept of genetic diversity being advantageous. High genetic diversity would typically increase the chances of some individuals surviving adverse conditions.
Option 3: "Reproducing more rapidly would be a good way to take advantage of plentiful resources."
This option suggests that rapid reproduction could be beneficial when resources are abundant. However, it does not explain why hydras would avoid asexual reproduction specifically when conditions are difficult.
Option 4: "Reproducing more slowly would be a good way to take advantage of plentiful resources."
This option suggests that slower reproduction could be advantageous when resources are plentiful. Again, it does not specifically address why hydras would avoid asexual reproduction under difficult conditions.
Therefore, the most reasonable explanation is Option 1: "The lack of genetic diversity could mean that all of the hydras die, depending on the situation."
