distribution of vasopressin receptors in the brains of voles determines aspects of mating behavior.
since marigolds deter asparagus beetles, growing asparagus next to marigolds will lead to lower beetle infestations.
nitrogen availability provided by legume planting increases peat moth growth rates in adjacent bogs.
expression of gcm transcription factor in neuronal progenitors leads to transformation of presumptive neurons into glial cells.

cells, communities, populations, organisms

Explanation:

1. Starch and glycogen are both polymers of glucose. Starch is the storage - form of glucose in plants and glycogen in animals. They don't contain ribose, aren't made in animals only (starch in plants), not for structural purposes (cellulose is for structure), and starch can be digested by humans.
2. Count the carbon atoms in the serotonin molecule structure. There are 10 carbon atoms.
3. A prediction is a statement about what will happen in the future. "Since marigolds deter asparagus beetles, growing asparagus next to marigolds will lead to lower beet infestations" is a prediction as it forecasts a future outcome based on a known relationship.
4. In the biological hierarchy, the order from smallest to largest is organisms, populations, communities, ecosystems. Organisms are individual living beings, populations are groups of the same species, communities are groups of different species in an area, and ecosystems include communities and their non - living environment.

3. Since marigolds deter asparagus beetles, growing asparagus next to marigolds will lead to lower beet infestations.
4. organisms, populations, communities, ecosystems
