Hi :D
For question 1 your answer would b C EVAPORATION
The Carbon Cycle goes from the environment through us then into the atmosphere kind of how evaporation does water; water would go to the environment then into us and evaporate into the sky
For question 2 your answer would be A EARTHS ROTATION
The result of Earth's rotation on weather patterns and ocean currents. The Coriolis effect<span> makes storms swirl clockwise in the Southern hemisphere and counterclockwise in the Northern Hemisphere.

For question 3 your answer would be C <span>Identical fossils were found on continents that were far apart.
There were fossil records matched up to continents that were supposed to be side by side at one point. </span><span>Fossils found on the east coast of Brazil match quite nicely with fossils found in western South Africa. Also, he noticed that a lot of the fossilized life found in the rock record didn't fit in the climates they were found in.

Answer:
You mean How does the contractile vacuole in a single celled organism maintain homeostasis?
If that was it then It pumps water out of the cell
Explanation:
· In an open system matter and energy can be transferred
· In a closed system only energy can be exchanged
· In an isolated system neither matter nor energy can be exchanged
· The cell has to be an open system because it needs to exchange matter and energy and the only way to do so is through an open system
· As an open system the cell allows nutrients to enter the cell and waste products to exit the cell
· The cell does this through the use of a semi-permeable membrane
· It needs nutrients in the forms of glucose, ions and many other molecules.
· The nutrients can come into the cell through either passive or active transport
· In passive transport the nutrients naturally move from a higher concentration gradient to a concentration gradient.
· During active transport the particle need to move against the concentration gradient. To do this the cell needs energy to transport the materials. The energy comes in the form of ATP.
