Answer: A (catabolism and Anabolism)
Explanation:
Metabolic pathway are basically divided into two categories.
1. Catabolic
2. Anabolic
Catabolic (degradation) pathways, where energy rich complex macramolecules are degraded into smaller molecules. Energy released during this is trapped as chemical energy, usually as ATP.
Anabolic (biosynthesis) pathways. The cells synthesize complex molecules from simple precursors. This needs energy.
Answer:
C
Explanation:
Many kinds of air pollution can't be seen, which means A is incorrect. Any kind of pollution can be harmful to you, which means B is incorrect too. Air pollution is very harmful but in most cases can't be directly seen, so C is correct. Pollution can be found everywhere, so D is incorrect also.
Explanation:
Since Charles found that the volume is directly proportional to temperature when the mass and pressure remain constant this means that with increase in temperature, there will be increase in volume.
Mathematically, 
at constant Pressure
This equation represents the relationship in Charles' law.
<span>(decreased variation in tail feather color because no form of the trait is advantageous) Due to the fact that the tail color is no longer a necessity, so it will eventually stop being needed and variation will decrease.</span>
Corrosion is when weather weakens and brakes apart rocks. An example would be the rocks at the beach that eventually begin to form holes and loose its mass due to the constant corrosion from the sand, water, and wind.
