Which do you think would adapt and survive overtime to a mass extinction? A starfish or an eel?
Harlamova29_29 [7]

Answer:

Starfish

Explanation:

This is an opinion questions, so there really isn't a right or wrong answer.  You could just as easily choose Eel.  Your task is to pick one and defend your reasoning.

I chose starfish because starfish have a long history of demonstrated adaptability to a wide variety of conditions.  Their armored skin protects them from a variety of predators, as does the poison that many of them contain.  They have the ability to regrow limbs, and even regrow entire starfish from certain body parts.  When it comes time to breed, starfish meet together in groups.  Each female releases a few million eggs from the gonads in each of her arms.  Each male then releases billions of sperm from each gonad in each of his arms, thus covering the eggs with sperm to fertilize them.

How might a comparison of the anatomy of two closely related animals such as lizards and snakes provide information about their
jenyasd209 [6]
There are two ways of working out the phylogeny (family tree) of living animals. One is by analyzing their genes; the other is to analyze the extent to which they are similar in form. In either case. the results can then be integrated with the fossil record. In principle, the two approaches should be complementary. Both should lead to a consistent account of how snake and lizard families descended from a single stem. More or less a greater number of shared traits would mean they recently diverged from a common ancestor.
