They can be broken by crossing over
Answer:
A. depend on a concentration gradient
Explanation:
Simple and facilitated diffusion are the two methods of transport of substances down their concentration gradient. In both processes, substances are moved from the region of their higher concentration to that of their lower concentration. Since simple diffusion and facilitated diffusion are passive processes, there is no requirement of energy input to drive them. Both are driven by the concentration gradient of the substances only.
Children can be 1/2 Ai or 1/2 Bi
Answer:
This is an example of adaptation due to a progressive mutation
Explanation:
At the beginning, the bacteria can use the galactose as carbon source for it needs, but since this food is getting out in every new generation. The new generations can be adapted to survive with smaller quantities of galactose until there will be one generation that can survive with any galactose source, when this offspring reach the area of the plate without galactose, then it can be grown in ant area.
