Overfishing occurs when more fish are removed from an ecosystem than can be maintained by the population,
Overfishing can lead to significant population declines in economically important species. The passage describes
additional impacts of overfishing on populations.

According to the passage, which mechanism explains the observed changes in fish size over time?
A. Smaller fish produce fewer eggs than larger fish do, so they contribute fewer offspring to the next
generation.
B. Fish that are small enough to escape fishing nets are more likely to survive than larger fish.
C. Scientists found that Atlantic silversides exhibited changes in feeding and foraging rates after four
generations of selection,
D. The average size of pink salmon returning to spawn decreased from 6.0 pounds to approximately 4.5
pounds.
Because there are not strictly green and yellow plants, this means that
the color can be affected by multiple genes. If it was only affected by
one gene then you would see only the two groups for the color, green and
yellow. The answer is D
<span>There are several genes that control the color.

Answer:
Human X and Y chromosomes determine the biological sex of a person, with XX specifying female and XY specifying male. Although the Y chromosome contains a small region of similarity to the X chromosome so that they can pair during meiosis, the Y chromosome is much shorter and contains many fewer genes.
Explanation:
The correct answer is option d - branch-like fiber extending in clusters from a neuron's cell body.
Axons are regions that extend from neuron cell membrane. The axon starts from a cell body portion called axon hillock. Then it extends to form a terminal towards the end that is adjacent to the target cell.
Axons are considered the primary transmission lines in the nervous system. They can be quite long. Some can extend to over a meter long, for example those of the sciatic nerve.
