- (C) agriculture
- (D) to move people
- (E) relocation
- (F) aerate soil
- (G) survival
- (H) dry out soil
--
Let's think first: Earthworm burrows help aerate soil, which is also good for plants. Most species construct burrows. Constructions by earthworms help aerate soil which is good for plants.... So the answer is [(F)]

- (A) chemicals
- (B) flavoring
- (C) glucose
- (D) energy
- (E) MSG
- (F) Energy.
- (G) chop sui
- (H) oxygen
--
Let's think first: Vesicle transport requires energy, so it is also a form of active transport. Synaptic vesicles glutamate transporter 5. Glutamate transport requires energy.... So the answer is [(D)]

Options:
- (A) A kernel
- (B) protein
- (C) food
- (D) Energy.
- (E) power
- (F) Joules
- (G) alleles
- (H) Energy
--
Let's think first: Molecules of tRNA bring amino acids to the ribosome in the correct sequence. Ribosome binding site, start and stop codons, protein coding sequence. Molecules of tRNA bring amino acids to the ribosome to create proteins.... So the answer is [(B)]


What is called when plants grow toward the sun or an artificial light?
Options:
- (A) Exfoliation
- (B) Brownian motion
- (C) heat energy
- (D) phototropism
- (E) photovoltaic
- (F) autumn
- (G) peachleaf willow
- (H) mitosis
--
Let's think first: Plants exhibit phototropism, or growing toward a light source. Many light sources such as the sun and most artificial lights produce unpolarized light. Plants exhibit phototropism, or growing toward the sun or artificial light.... So the answer is [(D)]
