50% because both are the same Genotyle dominant wise and recessive wise so it will have a fifty fifty chance of having wrinkled seeds

The faster a cheetah can run, the more likely it is to capture its prey. Cheetahs with longer legs are able to run faster than t

stealth61 [152]

Answer:

D

Explanation:

This is the more likely explanation, as there must be a limit to leg length in an animal that has to run very fast and strain their muscles and bones to the limit to do so.

As for the other options, there is no evidence to conclude that the genes that are involved in cheetahs leg length do not undergo mutation because the population exhibits a variety of leg lengths. Neither can we conclude that there are any isolated subgroups in the pupulation. Natural selection does act upon the traits involved in predation, as the question starts by saying that the faster a cheetah can run the more likely it is to capture its prey.

If cancer occurs only in dividing cells, how can the brain develop cancer even though all brain cells are differentiated and don

Makovka662 [10]

Explanation:

Cancer occurs in dividing cells only because genetic materials divide into two equal portions during division. This process may be interrupted by carcinogenes or mutagenes to make mutate cells and then render them as cancer cells. In the brain, the cells are differentiated and there is no chance to start division, then how can cancer be found in the brain.

Answer:

The options

A. A

B. B

C. C

D. E

The CORRECT ANSWER IS D.

E.

Explanation:

It is a regular occurrence for dialysis bags or dialysis tubing to be employed in permitting smooth movement of molecules when having to do with a fluid. These bags are normally evaluated to ensure that the client has adequate amount in th bag so as to be able to achieve the goal at hand.

If we have five dialysis bags being formed from a semi-permeable membrane which is impermeable to sucrose, they may be saturated with different concentrations of the sucrose with each of these bags being positioned in different beakers that have an initial amount of 0.6 M of a sucrose solution.

At ten minute intervals, the bags were massed and the weight was calculated to look for changes in the level of concentration. In this situation, the bag with the lowest initial concentration of sucrose is be the one that has its mass reducing over time and that is E.

The attached image confirms our answer as from the graph, option E shows the lowest initial concentration of sucrose.
