Juan was exposed to extremely cold temperatures for several days. His body is unable to maintain homeostasis, most likely resulting in which dangerous condition?

Answers

Answer: Hypothermia

Explanation:

Hypothermia is the condition which is caused when the body losses heat faster than it produces heat. The person under this condition feels very cold as the body temperature reaches below 95 F (35 C).

It can be adversely dangerous as it is not a normal body temperature at which the body works.

?The person can also get strokes and they can shiver for a longer period of time as the homeostasis of the body is not able to control the temperature of the body.

Since his body cannot bring his temp back to 98.6 and remain in homeostasis, he is risking developing Hypothermia.

Use your understanding of the phosphorus cycle to answer the questions provided.Phosphorus cycles between living things and the ______. ?

Answers

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.

Phosphorus cycles between living things and the environment, particularly the soil. This is the case with many other substances as well such as carbon. The cycling occurs due to the action of organisms which uptake and release phosphorus into the soil. Phosphorus exists in animals in many forms, particularly in the ATP molecule. When the animal dies, its remains are decomposed and the constituent ions are released into the soil, after which they are taken up by plants. Animals consuming these plants gain the phosphorus again, and the cycle continues.
