<span>In the "all or none" law of muscle contraction, it states that when the stimulus applied exceeds threshold then the the nerve sending signals to a few muscle fibers will give a complete response; contraction. Graded response is dependent on how many motor units have been recruited. The more motor units, the greater the force in the contraction.</span>
When the capture starts to increase, the fish population
from 50 capture start to 100 capture start upsurges. At 200 capture start, though,
the population augmented in the beginning up until it touched 300 months where
it significantly dropped.
Numerous environmental factors can affect the populace of
fish. First, when there is a hurricane, the fish population will be affected
because the water will move and change.
Second, pollution. When individuals pollute the ocean, it
affects the fishes’ ability to live.
Lastly, when there is a lot of hunters that feed on fish. This
may cause many fishes to be consumed and their population will be reduced.

thats dirty bruh but you could filter all the dirty stuff out and reuse the water
Answer;
-Allele frequency change
In single-gene traits, natural selection can lead to allele frequency change.
Explanation;
-Allele frequencies can change over time within a single population, and frequently differ between populations. This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift.
-Random forces lead to genetic drift. Sometimes, there can be random fluctuations in the numbers of alleles in a population. These changes in relative allele frequency, called genetic drift, can either increase or decrease by chance over time.
