Answer:
Prophase
Explanation:

Answer:
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.

If your heart beats 70 times per minute, everyday of the year, how many times does it beat in a year?
Answer:
36,792,000
Explanation:
Using some math, if you say that it beats at 70 pm, then you should look for how much it beats in an hour, which is 4200 (60x70). Then you have to take that number and multiply by 24, which is 100,800. In a day it beats about that amount. Then you take that number and multiply by 365, which is 36,792,000.

Explanation:
Without the greenhouse effect, temper on Earth would (F) be too cool or too hot. G) become constant. (H) increase sharply. (I) vary too much.
Answer: (F): Be too cool or too hot.
Explanation: The Greenhouse Effect on Earth is a process of when gases in the atmosphere capture the heat produced by the Sun. Without the Greenhouse Effect, the heat reflected by Earth's surface would be lost in space. The temperature on Earth would drop drastically low and this could lead to oceans/lakes freezing over and some living organisms to die out. This would make most life incapable of living on Earth.
