Answer:
overpopulation can occur when there are not enough preadators or the food web is out of balance, in some ecosystems overpopulation can really harm it as some organisms increase and decrease which can cause an extintion if it gets too out of hand.
Explanation: period.

<u>Answer:</u>
The<u> autonomic nervous system </u>is the part of the peripheral nervous system that directs the activity of glands, organs, and smooth muscles.
<u>Explanation:</u>
The autonomic nervous system (ANS) is a control mechanism that operates primarily unconsciously and controls body workings like respiratory rate, heart rate, pupil response, digestion, urination and sexual excitement. This method is the primary driving force for regulating the reply to fight or flight.
To regulate physiological functions, it controls involuntary responses. There are also two divisions to the ANS while these two splits have oppositional effects on their internal organs:
- the sympathetic division and
- the parasympathetic division.

IF THIS IS THE COMPLETE QUESTION WITH MULTIPLE CHOICE.
Two genes interact to produce various phenotypic ratios among F2 progeny of a dihybrid cross. Design a different pathway explaining each of the F2 ratios below, using hypothetical genes R and T and assuming that the dominant allele at each locus catalyzes a different reaction or performs an action leading to pigment production. The recessive allele at each locus is null (loss-of-function). Begin each pathway with a colorless precursor that produces a white or albino phenotype if it is unmodified. The ratios are for F2 progeny produced by crossing wild-type F1 organisms with the genotype RrTt.
9/16 Dark Blue 6/16 light blue 1/16 white
A) At least one copy of each dominant allele results in dark blue, at least one copy of either dominant allele produces light blue, and the absence of both dominant allele produces white.
B) If both dominant alleles are present, the result is dark blue. At least one copy of one specific dominant allele is required for light blue. If that dominant allele is not present, the result is white, regardless of whether the other dominant allele is present.
C) At least one copy of both dominant alleles results in dark blue; at least one copy of one of the dominant alleles also results in dark blue, but at least one copy of the other dominant allele produces light blue; and the absence of either dominant allele produces white.
MY ANSWER IS:
A) At least one copy of each dominant allele results in dark blue, at least one copy of either dominant allele produces light blue, and the absence of both dominant allele produces white.
