It seems that you have missed the necessary options for us to answer this question, so I had to look for it. Anyway, here is the answer. The two organisms that contain chloroplasts and eyespots are volvox and euglena. Hope this answers your question.
Answer:
D. A population with high genetic biodiversity is better able to respond to environmental stressors.
Explanation:
The genetic biodiversity of a species is the diversity of alleles that it possesses in its genetic pool. For a given gene, a population can have one or more alleles; and the more alleles the population has, it will be more diverse. Under normal conditions (without stress), the alleles that are present in high frequency in a population, are those that best respond to the environment where the population occurs. However, if some environmental condition changes and some type of environmental stress emerge (ie drought), it is possible that these alleles no longer respond equally effectively and then, it is possible that the alleles that on normal conditions occur with low frequency, are more adequate to face the stress. A population with fewer alleles (less genetic diversity) has terefore fewer options to deal with environmental stressors and<u> a population with high genetic biodiversity</u> will do this better.
Antithrombin is a protein molecule that inactivates several enzymes of coagulation system. It is a glycoprotein produced by the liver consisting of 432 amino acids and three disulfide bonds. The antithrombin found in the blood and the cell lining blood vessels function to prevent unwanted formation of clot.
In the earliest stages of development, all four organisms have a knobby head, gill slits, and a tail. These similarities tell us that all four of these organisms have a common ancestor.
