Options:
- (A) ferns
- (B) alpacas
- (C) complex
- (D) three
- (E) cracking
- (F) family
- (G) PDAs
- (H) ligt
--
Let's think first: Macroevolution occurs over geologic time above the level of the species. Few families rival Piperaceae for difficulties at the species level. Macroevolution can occur in the taxonomical level called family.... So the answer is [(F)]

- (D) glucose
- (E) decomposers
- (F) herbivores
- (G) producers
- (H) consumers
--
Let's think first: Consumers take in food by eating producers or other living things. Decomposers produce nutrients for producers. Decomposers make nutrients for organisms that become food for consumers.... So the answer is [(H)]

- (C) aerobic capacity
- (D) food and shelter
- (E) an organism's body
- (F) reproduce
- (G) barnacles
- (H) mixing genes up
--
Let's think first: Arthropods have a life cycle with sexual reproduction. Sexual reproduction mixes the genes up more than is possible with asexual reproduction. Arthropods have a life cycle with mixing genes up.... So the answer is [(H)]
