$\text{Metabolic rate} \propto m^{3/4}$

Question 1

Which of the following best explains how long legs help the desert ant survive in its environment?

Accepted Answer

Long legs elevate the ant's body above the hot sand, reducing heat absorption and preventing overheating.

Which equation correctly relates the rate of exchange of materials to the surface area and volume of a cell?

Accepted Answer

Rate of exchange $\propto$ cell surface area

Question 3

Which adaptation allows complex multicellular animals to efficiently exchange materials with their environment?

Accepted Answer

Developing specialized, extensively branched or folded internal structures

Question 4

Which of the following is NOT a function of epithelial tissue?

Accepted Answer

Question 5

Which connective tissue type is primarily responsible for binding epithelia to underlying tissues and holding organs in place?

Accepted Answer

Loose connective tissue

Question 6

Which muscle tissue type is responsible for voluntary movement in vertebrates?

Accepted Answer
