Answer:
The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth.
Explanation:
<u>The water cycle is an illustration of how water continuously moves or circulates between the atmosphere and the various parts of the earth. </u>
<em>Evaporation of water from the surface of the earth by the thermal energy from the sun causes water to leave the surface of the earth into the atmosphere. When the atmospheric water vapor (humidity) at the upper strata of the atmosphere becomes high, the vapor condenses to form clouds which later forms precipitation that falls back to the surface of the earth.</em>
The ocean's tidal energy does not cause water to cycle on earth.

Answer:
D.
Anaphase away. So, this means that The tetrads are pulled apart, while the Sister Chromatids are still together.
Explanation:
Collagen is a substance that is made up of amino acid linked together to form long, branched polypetide (tertiary protein chains). Thus COLLAGEN is the protein.
I believe the answer is B, primary active transport. Root hair cells in plant use active transport to absorb mineral ions such as nitrates from the soil. The concentrations of minerals in the soil are lower in the soil than in within the root hair cell, therefore the transport will be against the concentration gradient which does not favor diffusion, therefore the pant has to use active transport.
