There are equal amounts of immigration and emigration. D. The frequency of each phenotype does not change.
The gene pool gets smaller in each generation, which is the characteristic of a population that is in Hardy- Weinberg equilibrium. The correct option is A.
What is a gene pool?The gene pool encompasses all of a species' genetic diversity. The gene pool's size can change. When organisms have mutations that are passed down to the next generation, the gene pool expands.
When all of the organisms carrying a particular allele die before having offspring, the gene pool shrinks.

Explain why the biodegradation of plastic might be more hazardous to the environment than the presence of plastic as marine debris.
Answer:
they generate a large amount of macrobiotic flora which can cause diseases to humans as well as animals
Answer:
While plastic is not generally considered biodegradable, it can be broken down by the action of photodegradation and certain microbes. The breakdown products of plastic, however, are extremely toxic to marine life and once the plastic breaks down they are free to enter into the food chain. Therefore, while plastic marine debris is hazardous and dangerous to marine organisms, the toxic breakdown products of plastics have the potential to do even more damage.

Saturn is close to Polaris during some years
true or false
Saturn is not close to polaris
Polaris disappears into the horizon as seen from the equator, and is not visible from the south of the equator. Finding Polaris in the Northern Hemisphere indicates that you are aware of the direction north.
What is the importance of Polaris?Directly above Earth's North Pole is the Pole Star, or Polaris. Due to its location over the North Pole, the pole star is aligned with the earth's axis. As the sole star that is stationary, it is crucial for orientation.
It makes a fairly small circle over the course of a day since it is so close to the celestial equator. As a result, Polaris is a trustworthy indicator of north, since it always remains in nearly the same location in the sky.
Therefore, it is false that Saturn is close to Polaris during some years.
