Question

The following question is worth up to 10 extra points added to the lowest of the 4 lecture test grades that I keep at the end of the semester. Please note that this assignment is untimed so take your time answering the questions prior to submission. In general, locomotion on land will require more energy than locomotion in water. By integrating what you have learned about animal form and function in this course, discuss at least 3 evolutionary adaptations of mammals that support the high energy requirements for moving on land. Your answer should be in complete sentences in paragraph format. HTML Editor BIUA- A IE x x, Vx AT T 12pt ED

Answer 1

The animals in land needs more energy for moving than that of animals in water. The evolutionary adaptation which supports this are following--

a) they have well developed closed circulatory system that means all parts of body is interconnected by blood vessels, artarty, veins. Which makes the oxygen supply in required rate in every part of the body.

b) the heart is divided into 4 chambers. As a result blood filled with oxygen and blood filled with CO_{​​​​​2}​​​​ are not mixed together.

c) they have well functional lungs which is responsible for the oxygen input and carbon dioxide release. More the cellular activity will occur more the Carbon dioxide will produced so it is highly required to remove those from the body.
