Bacteria can reproduce through asexual or sexual reproduction. Environmental conditions for a particular bacteria species are good and the bacteria are thriving. Which form of reproduction will the bacteria most likely use?
A. The bacteria will most likely reproduce through asexual reproduction to maintain genetic continuity.
B. The bacteria will most likely reproduce thual reproduction to maintain genetic continuity.
C. The bacteria will most likely reproduce through asexual reproduction to increase genetic diversity.
D. The bacteria will most likely reproduce thual reproduction to increase genetic diversity.
Is the answer A?
1. C) Organisms must reproduce to continue the species.
2. D) Sexual reproduction is shown because the offspring received half its genetic material from one parent and half from the other parent.
3. A) The bacteria will most likely reproduce through asexual reproduction to maintain genetic continuity.
4. A) If the offspring inherits a genetic combination that includes a harmful trait, it could decrease the organism’s chance of survival.
5. B) If gametes were not haploid, the offspring would have double the number of chromosomes it is supposed to have.
Correct.

Which statement is most supportive of the claim that genetic diversity is an advantage of sexual reproduction?(1 point)
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?(1 point)
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.**********

Hydras are animals related to coral and jellyfish. Hydras can reproduce sexually or asexually. Why would hydras avoid reproducing asexually when conditions are difficult? (1 point)
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.
