Which is the best explanation for how air masses move across the United States

Warm air rises, expands, then cools. As cool air sinks it may cause precipitation. Some air masses such as the MT which originate in warm environments carry humid air and cause heavy precipitation in some areas.

Explain what type of logging would most likely necessitate reforestation afterwards.

Clear-cutting logging would be more likely to necessitate reforestation afterwards than selective cutting. Clear-cutting removes all trees in an area and results in more significant environmental damage, making it more difficult for the trees to regrow naturally. With selective cutting only some of the trees are harvested, so the overall ecosystem is preserved which makes it more likely that trees will be able to regrow naturally.

Plants need nitrogen in order to form amino acids and absorb this in the form of nitrates from the soil. They do this with the help of their roots. In a waterlogged environment, roots start to decompose due to the lack of oxygen. This affects their nitrate absorption capacity and plant growth is stalled.

Marine science help!! 15 points! Cesium is a radioactive element which was released into the ocean after the Fu kushima nuclear power plant meltdown in 2011. Cesium's half-life is 30 years, which means that for every unit of cesium, half of it will decay over 30 years. How does this affect the human populations that eat fish from this area? A: Cesium's half-life is relatively long, so biomagnification could become a concern. B: All of the cesium will decay in approximately thirty years; therefore, humans can just avoid eating the contaminated fish for thirty years. C: Cesium levels will be acceptable in a short time, so biomagnification is not a concern and humans can eat fish as normal. D: Cesium will only decay by half in fifteen years, so human populations should avoid eating fish in this area and avoid contamination. I'm stuck between A or D... :/

Answer:

A is correct

Explanation:

Since the half-life of Cesium is 30 years, that mean that passing this period of time there is going to be the half of mass of this element in ocean. Of course since day 1 until year 30, there will be plenty of generations of the marine living things, so what is going to happen is that this element can be absorb by the algae or plants from the ocean, Cesium is going to fixed in tissues, so when small fish are going to eat, they are going to accumulate Cesium in their tissues (but a bigger concentration than the producer), when another animal eat this small animal is going to repeat the process, in that way biomagnification will be a concern to humankind.

Explain what happens to the human body if one of the body systems is not functioning properly. Make sure to include the idea of homeostasis in your evidence and reasoning.

If one body part is not working properly, it affects others also. The direct influence of any such abnormality can be seen of the homeostasis of the body. If an infection occurs, it leads to release of the signals which also increase the body temperature, and homeostasis is disturbed. Similar is the case of the nervous system. If it is not working properly, hormones related to maintenance of homeostasis are affected and ultimately, other body systems including excretory and endocrine are directly affected. If circulatory system is affected, then plasma, which acts as a buffer system is hampered and a direct influence can be seen on heart and kidneys also.
