1. which term best describes an organism that is warm-blooded?

a. ectotherm
b. exotherm
c. endotherm

Explanation:

Question 2 (Which term best describes an organism that is cold - blooded?)

Ectotherms are organisms that rely on external sources of heat to regulate their body temperature, which is characteristic of cold - blooded organisms. Exotherm is not the correct term for cold - blooded organisms (it is more related to chemical reactions that release heat). Endotherms are warm - blooded organisms that generate their own body heat. So the term for a cold - blooded organism is ectotherm.

Endotherms are organisms that can maintain a relatively constant body temperature by generating heat internally, which is the definition of warm - blooded organisms. Ectotherms are cold - blooded, and exotherm is not the correct term for warm - blooded organisms (it is related to heat - releasing reactions). So the term for a warm - blooded organism is endotherm.

Answer:

a. ectotherm
