Mrs. Jones, who has been caring for her terminally ill mother for a year now, has continued to work at a demanding job, as well as parent three active teenagers. These long-term stressors should <u>decrease</u> the number of NK cells, thereby<u> </u><u>impairing</u> immune system functioning.

<u>Explanation:</u>

In this adaptive cycle, the two major structures at work are the nervous system particularly the brain and the immune system.Prolonged stressful environments reduce cytotoxic potential at NK. There is a component P, which facilitates the improvement in macro-phage cytokine formation under stressful circumstances.

Acute stress improves activation of T cells by means of a beta 2–adrenergically mediated cycle that is blunted throughout chronic stress. Psychological stress affects the ability of the immune system to generate antibodies in reaction to a vaccine and thus renders the organism more susceptible to infection.

Most of the oxygen in the atmosphere is made by algae. Where do most of the algae live?
sveticcg [70]
Coastal Ocean!

Explanation: It’s important to remember that although the ocean produces at least 50 percent of the oxygen on Earth, roughly the same amount is consumed by marine life. Like animals on land, marine animals use oxygen to breathe, and both plants and animals use oxygen for cellular respiration. Oxygen is also consumed when dead plants and animals decay in the ocean.

This is particularly problematic when algal blooms die and the decomposition process uses oxygen faster than it can be replenished. This can create areas of extremely low oxygen concentrations, or hypoxia. These areas are often called dead zones, because the oxygen levels are too low to support most marine life.

NOAA’s National Centers for Coastal Ocean Science conducts extensive research and forecasting on algal blooms and hypoxia to lessen the harm done to the ocean ecosystem and human environment.

Which of these is a difference between DNA and RNA?
vodka [1.7K]

Like DNA, RNA is made up of nucleotides. There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

What is the difference between evaporation and transpiration
Leviafan [203]
Evaporation<span> occurs when water changes from a liquid state to a gaseous state. It can happen anywhere there is water – in the soil, lakes, oceans and plants. When it occurs in plants, water is lost through microscopic pores in the plant's leaves</span>
