Answer:HIV attacks a specific type of immune system cell in the body. It's known as the CD4 helper cell or T cell. When HIV destroys this cell, it becomes harder for the body to fight off other infections. When HIV is left untreated, even a minor infection such as a cold can be much more severe.

-4. The angle of the earth affects the amount of energy an area receives
-5.More sunlight reaches the Earth at the equator
-6.Topics(near the equator) have warm air that rises,creating areas of high pressure.
-7.North and South poles have low air that sinks,creating areas of high pressure.

D. They both help organisms to move.
Answer:
<em>Water will move out of a cell.</em>
Explanation:
A hypertonic solution will have higher solute concentration and lesser solvent concentration. If a cell is placed in such a solution, then the concentration of the solvent will be more inside of the cell as compared to outside of the cell. As a result, the solvent will move out of the cell. If an excess of solvent is lost, the cell might shrink to dangerous levels.
Hence, from the above description we can justify that water will move out of a cell which is placed in a hypertonic solution.
