Answer: Comparing the rates of predation on whitefly nymphs coated with a nontoxic dye versus the undyed whitefly nymphs.
Explanation:
A hypothesis refers to an assumption, which is proposed for the sake of an argument which is tested to ascertain if it's true.
The hypothesis can be tested by comparing the rates of predation on whitefly nymphs coated with a nontoxic dye versus the undyed whitefly nymphs.
Answer: depolarization; hyperpolarization
Explanation:
At resting potential (absence of stimulus), the cell membrane of a neuron is said to be polarized with a net negative charge within due to more potassium (K+) ions present than sodium (Na+) ions.
However, an impressed stimuli reverses the ions content as K+ ions flows out and quickly replaced by Na+ ions, resulting in a decrease in membrane potential and a more positive cell membrane. Thus, depolarization occurs.
An increase in the membrane potential (so that it becomes more negative) is called hyperpolarization.

Answer:
This outcome in a hybrid zone is known as <u><em>fusion</em></u>.
Explanation:
In the field of biology, hybrid zone can be described as the area where closely-related species can interbreed and produce hybrid organisms. Reinforcement can be described as the phenomenon by which a hybrid zone develops between full species barriers. Hybrid speciation can be described as the phenomenon by which a new species forms as the direct result of mating between members of two existing species.
No, stereopsis is the perception of depth produced by the reception in the brain of visual stimuli from both eyes in combination. So it's false
