- (B) Earth orbiting the Sun
- (C) Electrical energy
- (D) faster movement
- (E) scarce resources
- (F) aerobic capacity
- (G) Localized damage
- (H) rapid expansion
--
Let's think first: Cell division is more complex in eukaryotes than prokaryotes. Eukaryotes move much faster than prokaryotes. Cell division is more complex in organisms with faster movement.... So the answer is [(D)]


The trcipes femoris is used to move what?
Options:
- (A) heat
- (B) Mass
