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

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

The most appropriate response to the question of why hydras would avoid reproducing asexually when conditions are difficult is:
**The lack of genetic diversity could mean that all of the hydras die, depending on the situation.**
Asexual reproduction produces genetically identical offspring, which can be detrimental in changing or harsh environmental conditions, as the entire population may be susceptible to the same threats or diseases. By reproducing sexually, hydras can increase genetic diversity, which can enhance survival rates in challenging environments.

The correct response is:
**resistant to**
If a parent bacterial cell is able to survive in the presence of the antibiotic penicillin, it is likely that its subsequent generations will inherit this resistance to penicillin.

The correct response is:
**two**
In binary fission, one cell divides to produce two daughter cells.
**two**
In binary fission, one cell divides to produce two daughter cells.

The correct response is:
**asexually.**
Both potatoes (which can reproduce asexually through methods such as tubers) and bacteria (which typically reproduce asexually through processes like binary fission) can reproduce asexually.
**asexually.**
Both potatoes (which can reproduce asexually through methods such as tubers) and bacteria (which typically reproduce asexually through processes like binary fission) can reproduce asexually.

The correct response is:
**replicates.**
In binary fission, the DNA in the parent cell replicates before the cell divides to produce daughter cells.

The correct response is:
**The trait is recessive, and the child inherited a recessive allele from each parent.**
In this situation, both parents can be carriers of a recessive trait (having one recessive allele and one dominant allele) and yet not exhibit the trait themselves. The child could then inherit the recessive allele from both parents, leading to the expression of the trait.
