Answer:
A.
Explanation:
Predators hunt prey. (Obviously). As such, they help control the population of that particular prey-species. If the predator species is removed from the equation, 2 times are changed.

Answer:
It's an explanation in molecular biology, of the flow of genetic information provided in a biological system.
This is called the G1 phase I'm sure.
Answer:
The temperature is staying the same. In the graph when it shows solid/liquid and liquid/gas, the temperature stays the same until it changes. This is because it reached it's melting point/vaporizing point. For example, a solid gets heated up, it then reaches it's melting point but it can't go higher than that because it isn't fully a liquid yet, once it's a liquid it will then continue to rise in temperature.
I don't think I put enough detail into that explanation but I hope this helps your problem.
