Answer to Question 1

ANS: A
Active transport is able to reverse passive diffusion. It does require energy to perform because it is not
a passive process like diffusion. Information can be found in the section Environmental Factors
Influence the Success of Marine Organisms.



Answer to Question 2

ANS: A
Humans have a high internal temperature relative to our surroundings. It remains constant despite
changes in the environment, making us endothermic. Information can be found in the section
Environmental Factors Influence the Success of Marine Organisms
