Explanation:
Because there's a higher concentration of oxygen molecules outside the cell compared to the cell's cytoplasm, you'll see that oxygen diffuses into the cell along this concentration gradient. ... Because the molecules are moving at random, some will move out of the cell, but most will be moving in in this case.
Density-dependent limiting factors cause a population's per capita growth rate to change—typically, to drop—with increasing population density
<span>Well active transport absolutely moves substances against their concentration gradient (answer C), although I dislike how the other answers could probably be argued for. This seems to be a case of pick the "best" answer</span>
Answer:
0%
Explanation:
Normal female genotype = 
Genotype of a man with hemophilia = 
Crossing the two in marriage:
x
Progeny: 
<em>The two sons from the cross have the genotype </em>
<em> and are therefore free from hemophilia.</em>
Hence, the percentage of their sons that will have hemophilia is zero (0).
