Overfishing occurs when more fish are removed from an ecosystem than can be maintained by the population,
Overfishing can lead to significant population declines in economically important species. The passage describes
additional impacts of overfishing on populations.

According to the passage, which mechanism explains the observed changes in fish size over time?
A. Smaller fish produce fewer eggs than larger fish do, so they contribute fewer offspring to the next
generation.
B. Fish that are small enough to escape fishing nets are more likely to survive than larger fish.
C. Scientists found that Atlantic silversides exhibited changes in feeding and foraging rates after four
generations of selection,
D. The average size of pink salmon returning to spawn decreased from 6.0 pounds to approximately 4.5
pounds.
Answer:
The correct answer is "exchange of genetic information between parental chromosomes".
Explanation:
Homologous recombination is a genetic recombination that occurs when two similar or identical molecules of DNA exchange some of its nucleotide sequences. This type of recombination is most widely used for DNA repair purposes, however this is not distinctive of eukaryotes as prokaryotes use it as well. Therefore the most significant an unique role of homologous recombination in eukaryotes is the exchange of genetic information between parental chromosomes. This particular function is known as chromosomal crossover and it is only found in eukaryotes.
There will be more acid particles to interact with the limestone at higher concentrations hence the rate of reaction increases.
The question is incomplete but I will try to help you the much I can. If you have carried out the experiment properly, you will notice that the rate of reaction increases as the concentration of the acid increases.
This is because, if the amount of limestone is held constant and the concentration of acid is increased, there will be more acid particles to interact with the limestone at higher concentrations hence the reaction proceeds faster.
