Answer:
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom. A good comparison of the nucleus to the atom is like a pea in the middle of a racetrack. (10-15 m is typical for the smaller nuclei; larger ones go up to about 10 times that.)
the answer should be b) molecules because molecules are what creates a amino acid
Answer: 266.67 s
Explanation:
Average velocity is the rate of change of displacement.
Bird flies 2400 m due west at an average velocity of 9.0 m/s.
Given, average velocity, v = 9.0 m/s
Displacement, d = 2400 m
Thus, bird was in flight for 266.67 s to fly from nest to land in a tree 2400 m due west.
