6 0

The body uses different muscle groups to generate motion. In running and swimming, your muscles are working to accelerate your body and keep it moving. In weightlifting, your muscles are working to move a weight. Exercise means muscle activity! As you use your muscles, they begin to make demands on the rest of the body. In strenuous exercise, just about every system in your body either focuses its efforts on helping the muscles do their work, or it shuts down.

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>

<h2>Advantage of plant kingdom</h2>

Explanation:

Capacity tissue to sustain development and a defensive coat give seeds their prevalent transformative preferred position.
A few layers of solidified tissue forestall drying up, liberating propagation from the requirement for a steady stock of water.
<em>Flowering plants have a regenerative favorable position </em>over gymnosperms due to various adjustments, for example, having blossoms t consider fertilization and organic product for seed dispersal.
Fertilization can be permitted by wind, or by dust being conveyed by creatures.
Seed and pollen were innovative structures that improvement of the undeveloped organism,to vanquish dry land and permitted seed plants to break their reliance on water for proliferation.
The dust grains are the <em>male gametophytes, which contain the sperm (gametes) of the plant.</em>
