Have you ever watched a caterpillar turn into a butterfly? If so, you're probably familiar with the idea of alife cycle<span>. Butterflies go through some fairly spectacular </span>life cycle<span> transitions—turning from something that looks like a lowly worm into a glorious creature that floats on the breeze. Other organisms, from humans to plants.</span>
Diastole<span> is the part of the cardiac cycle when the heart refills with blood following </span>systole<span>(contraction). Ventricular </span>diastole<span> is the period during which the ventricles are filling and relaxing, while atrial </span>diastole<span> is the period during which the atria are relaxing.</span>
Yes, it is possible that evolution occurs in this case.
At first, the new insecticide is effective against the boll weevil. Spraying the insecticide will kill the boll weevil in a way. The insecticide might attack boll weevil enzyme or any part of its organs.<span>
But some of them might have a mutation that renders the insecticide ineffective. The mutation probably happens to DNA that code the enzyme or protein that targeted by the insecticide, makes the insecticide completely ineffective.
The next spray will kill all old organism, leaving the new resistant organism in less competition area. This will allow the resistant organism to grow fast and eventually replace all the old organism in the area.</span>
ATP? Adenosine TriPhosphate
Answer:
Mutation causes brand new alleles the others just modify the rates at which preexisting alleles appear in the population.
