List The Differences Between The Hearts Of Vertebrates That Live In Water And The Hearts Of Vertebrates

Answers

Answer 1

Answer: All vertebrates have circulatory systems based on a common plan, and so vertebrate systems show much less variety than do those of invertebrates. Although it is impossible to trace the evolution of the circulatory system by using fossils (because blood vessels do not fossilize as do bones and teeth), it is possible to theorize on its evolution by studying different groups of vertebrates and their developing embryos. Many of the variations from the common plan are related to the different requirements of living in water and on land.

Explanation:

Answer 2
Since all the vertebrae‘s are in different environments they have to adapt to there surrounding so a cougar won’t have a heart in the same place as a fish

If you were asked to create an organizational scheme of your family members, how would you go about doing it? When you stop and think about it, there are several ways to accomplish this. You could outline how relatives are related to each other, or maybe you would sort them based on where they lived. You might even organize them based on characteristics that they have in common, such as hair colour, eye colour, and height.
