Options:
- (A) organs
- (B) Glial cells
- (C) nerves
- (D) Structural units
- (E) voltage
- (F) Storage units
- (G) Critical care
- (H) A computer
--
Let's think first: Neurons are the structural and functional units of the nervous system. Glial cells perform critical functions in the nervous system. Neurons are the structural and functional units of where the glial cells perform critical functions.... So the answer is [(B)]


What occurs in gametes?
Options:
- (A) offspring
- (B) pollen
- (C) resistance
- (D) Energy
- (E) Energy.
- (F) heat
- (G) syngamy
- (H) glucose
--
Let's think first: Gametes then unite in fertilization and form a diploid zygote. Syngamy produces a diploid zygote. Syngamy occurs in gametes.... So the answer is [(G)]
