How is the phosphorus cycle different from the oxygen, nitrogen, and carbon cycles?

a.

It occurs at the fastest rate.

b.

It is not essential to life.

c.

It does not occur naturally.

d.

It does not involve the atmosphere.

Answers

Answer:

The cycle only involves the lithosphere, hydrosphere, and biosphere, with no role in the atmosphere. The reason the atmosphere is not involved in that at the natural temperature and pressure of the environment, phosphorus and its compounds are usually in solid or ionic (usually phosphate ion) form. It is also a very slow nutrient cycle, with a major source of the nutrient being determined by tectonic activity that upwells the nutrients from deep in their earth’s core through volcanic activity.

Explanation:

The movement of materials from the plasma membrane, through endosomes, and then to lysosomes describes which type of pathway?.

Answers

Answer:

Below

Explanation:

The routes that lead inward from the cell surface to lysosomes start with the process of endocytosis, by which cells take up macromolecules, particulate substances, and, in specialized cases, even other cells. In this process, the material to be ingested is progressively enclosed by a small portion of the plasma membrane, which first invaginates and then pinches off to form an endocytic vesicle containing the ingested substance or particle. Two main types of endocytosis are distinguished on the basis of the size of the endocytic vesicles formed. One type is called phagocytosis (“cellular eating”), which involves the ingestion of large particles, such as microorganisms or dead cells via large vesicles called phagosomes (generally >250 nm in diameter). The other type is pinocytosis (“cellular drinking”), which involves the ingestion of fluid and solutes via small pinocytic vesicles (about 100 nm in diameter). Most eucaryotic cells are continually ingesting fluid and solutes by pinocytosis; large particles are most efficiently ingested by specialized phagocytic cells.
