In order to increase the rate of diffusion of materials in and out of the cell, the following modification can be done to the cell:
1. the shape of the cell can be changed to one that has high surface area to volume ration, for example sphere.
2.The cell can also divide into two in order to increase the surface area to volume ratio.
Definition. The hypothesis accepted to be true if the null hypothesis is rejected based on statistical evidence. Supplement. In the statistical testing of hypothesis, the two rival hypotheses are the null hypothesis and the alternative hypothesis.
Answer:
0 mya, 175mya, 250mya, 400mya
Explanation:
The substance which highest million year ago should be more in-depth in the soil hence 400mpa should occupy the highest depth below the ground.
During the S phase in the cell cycle, the chromosomes are replicated so that there are two copies. These copies are necessary so that each daughter cell created during the M phase will have an identical copy of the DNA.
Therefore, the answer is A: The DNA must be replicated.
The chromosomes joining, cell membrane expanding, and cytoplasm separating all happen during the M phase (mitosis).
