2.3 - Metabolic Rate

Question 1

How can metabolic rate be measured?

Answer 1

-Respirometers
-Oxygen probes
-Carbon dioxide probes
-Calorimeters

Question 2

What do organisms with high metabolic rates require?

Answer 2

More efficient delivery of oxygen to cells

Question 3

What type of circulatory system do birds and mammals have?

Answer 3

Complete double consisting of 2 atria and 2 ventricles

Question 4

What type of circulatory system do amphibians have?

Answer 4

Double incomplete consisting of 1 atria and 2 ventricles

Question 5

What type of circulatory system do fish have?

Answer 5

Single circulatory system consisting of 1 atria and 1 ventricle

Question 6

What do complete double circulatory systems enable?

Answer 6

They enable higher metabolic rates to be maintained

Question 7

What happens when oxygenated and deoxygenated blood are mixed together?

Answer 7

The oxygenated blood will be able to be pumped out at a higher pressure, enabling more efficient oxygen delivery to cells.
