Overview

If you have a dry, flaking scalp, you may suspect dandruff. But it could be a sign of dry scalp. Dandruff and dry scalp have the same main symptoms, which are falling flakes and an itchy scalp, but they are two different conditions.

In dry scalp, the skin gets irritated and flakes off. With dandruff, the cause is too much oil on the scalp. That excess oil causes skin cells to build up and then shed. Knowing which of these conditions you have can help you get the right treatment and banish those flakes for good.

Answer:

stratum corneum

Explanation:

its the outermost layer which generates dandruff (which is dead skin) skin grows from the inside, so it would make sense that the outermost layer releases dandruff/dead skin flakes

Explain why you know that diuron caused the coral to bleach.​​​​​​​

Answers

When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white. Warmer water temperatures can result in coral bleaching. ... This is called coral bleaching. When a coral bleaches, it is not dead. So basically diuron is stressing the plants.

Diuron will cause the coral to bleach.​​​ when the coral expels the algae that are living in their tissues.

Diuron simply refers to the trade name for DCMU which is an herbicide and algaecide ingredient that's used in controlling grasses and weeds.

It should be noted that diuron affects the salinity of ocean water and this is where coral reefs propagate. This can bring about a long-lasting impact on corals.

The algae which the coral polyps feed on is affected by the diuron and this brings about the bleaching of the coral. In this case, the exposure to higher diuron concentrations will lead to the pale or bleaching of corals.

In conclusion, when the corals' bleach, it'll expel the algae that are living in their tissues and then turn to white.

Finally, near the equator ( 0-30° North and South) the NPP is relatively the same. Why is that?

Once on the ground, the air returns to the equator. This convection cell is called the Hadley Cell and is found between 0 degrees and 30 degrees N. There are two more convection cells in the Northern Hemisphere.The air that rises at the equator does not flow directly to the poles. Due to the rotation of the earth, there is a build up of air at about 30° north latitude.
