For a fish to be buoyant, or float, it must displace less water or the same amount of water as its own body mass. ... Many fish use swim bladders to help them with quick depth changes. These bladders fill with air to help fish rise or release air so fish can sink, often in conjunction with forward movement.
Answer:
A. carbon dioxide molecules C. glucose molecules
Explanation:
Your answer will be interphase .
The answer to this question would be hypertonic.
If the chloroplast is going to be pushed against the cell wall, probably the water around the cell wall is decreased, causing it to suck up the water inside. Then, the solution must be causing the cell to lose water. The cell will lose water if put in a hypertonic solution. In a hypertonic solution, the osmotic pressure of the solution is higher than the cell, make it attract water from cells.
Answer: 20%
Explanation:
Recall that the sum of all nitrogenous bases is equal to 100%.
Hence: A + C + G + T = 100%
Now, since adenine nucleotides is 30%, then thymine is 30% as well (A = T). Thus, the total of both is 60%.
From 100 remains 40% which is divided equally between guanine and cytosine, so each is 20%.
Thus, the percentage of the same DNA molecule that would be expected to be guanine nucleotides is 20%
