In the guppie simulation, what happens to the brightest guppies when there are large numbers of predators? a. their population stays the same b. their population increases in number c. their population decreases in number d. their genes adapt to make them less bright, or duller in color

The correct answer is C. Their population decrease in number .

The population of bright guppies will decrease in number if there is large number of predators.

Guppy in another name it is referred to as rainbow fish. It is a fish which is tropical and it is distributed widely. They adapt in different ecological conditions and environment.

Guppies they feed on benthic algae and larvae of an insect. In the field of behavioural, evolution, and ecology guppies are being used as model organisms.

Some differences between the sympathetic and parasympathetic nervous systems:

Explanation:

- Neurotransmitters: norepinephrine in sympathetic (adrenergic fibers) and acetylcholine in parasympathetic (cholinergic fibers)

-The sympathetic nerves have their origin in the spinal cord (between segments T-1 and L-2) and from there to the paravertebral sympathetic chain, then in tissues and peripheral organs.

- The parasympathetic nerves have their origin in the brain stem, mainly in the cranial nerve nuclei III (oculomotor), VII (facial), IX (glossopharyngeal) and X (vagus) and in the sacral medulla.
