increase movements to find a sunny area. D) bask in a sunny, exposed area. E) begin involuntary
shivering of their skeletal muscles. - ANSWER B Topic: Overview
Knowledge/Comprehension 2) Which choice best describes a reasonable evolutionary mechanism
for animal structures becoming better suited to specific functions? A) Animals that eat the most food
become the most abundant. B) Animals that restrict their food intake will become less abundant. C)
Animals with mutations that give rise to effective structures will become more abundant. D) Animals
with inventions that curtail reproduction will become more abundant. E) Animals with parents that
continually improve their offspringʹs structures will become more abundant. - ANSWER C Topic:
Concept 40.1
Knowledge/Comprehension 3) Evolutionary adaptations that help diverse animals exchange matter
with the environment include A) gastrovascular activity, two-layered body, and torpedo shape. B)
external respiratory surface, small size, and two-layered body. C) large volume, long tubular body,
