The right option is; B) G0 phase
Neurons are in the G0 phase.
The G0 phase is a stage in the cell cycle in which cells do not divide or prepare for division but continue to carry out its normal functions for the rest of the organism's life. This phase is the resting phase of the cell and it is seen either as an extended G1 phase or a different stage that occurs outside of the cell cycle. Cells in the G0 phase include neurons, liver cells and heart muscle cells.
Phosphorus cycles between living things and the SOIL
Explanation:
Phosphorus flows in a cycle within rocks, water, soil and sediments, and organisms. The phosphorus cycle is the biogeochemical cycle that represents the action of phosphorus within the lithosphere, hydrosphere, and biosphere. Phosphorus is an essential element for all sorts of life. As phosphate (PO4), it delivers up an essential part of the structural core that holds DNA and RNA mutually.

In the movie Finding Nemo, there are several examples of parasitism.
Parasitism is a type of symbiotic relationship in which one organism benefits at the expense of another organism. The organism that benefits is called the parasite, while the organism that is harmed is called the host.
In conclusion, parasitism is a type of symbiotic relationship in which one organism benefits at the expense of another organism.

Every year 20,000 species go extinct. Thus, the correct option for this question is D.
Species may be defined as a cluster of organisms that can significantly reproduce with one another in nature in order to produce fertile offspring. It involves identical organisms that interbreed with one another in order to exchange genes. It is responsible for creating fertile organisms.
Species extinction is the ecological force that derives the mechanism of elimination of species from their native environment. This stimulates due to varieties of external influences like lack of food, space, mating selection, involvement of human activities, the action of predators, etc.
So, due to these external influences, it is found in research that approximately 20,000 species go extinct every year.
Therefore, every year 20,000 species go extinct. Thus, the correct option for this question is D.

Answer;
-Since sunlight is where most of the energy in an ecosystem comes from, there is less sunlight deep in a lake meaning less organisms can survive.
Explanation;
-The reason why many plants don't live deep below a lake's surface is because lakes don't normally have chemical vents. Thus, making it hard for producers to find any sources of energy in the dark, deep waters of the lake.
-Since the deepest parts of a lake receive the least light, the ability of submerged macrophytes (plants larger than algae) to establish colonies is limited.
-The combination of low oxygen levels and low light limits the growth of plant communities at great depths; many plants living in very deep water have adaptations such as elongated stems or long structures so that at least some of the plant is in the water nearer the surface where it can photosynthesis.
