The answer is genetic drift (bottleneck effect)
<span>There are 4 basic mechanisms of evolution - mutation, genetic drift, natural selection, and gene flow (migration). Genetic drift is a change in the frequency of alleles in a population as a result of random sampling of organisms. One of the examples of genetic drift is the bottleneck event. </span>The bottleneck event means drastic reduction of the population size because of environment changes. The consequence of this is the reduction of genetic variation. This is what happened to the population of worms after tree falling.
<span>The correct statement is letter C. All arteries except the pulmonary artery carry oxygen-rich blood. Most arteries are responsible for the delivery of oxygen and nutrients to all cells and the pulmonary veins are the one who transfer oxygenated blood from the lungs to the heart.</span>

Ithe insect eats the plant
Explanation:
Usually, as the chain goes on, more energy is lost. So, the first organism would have the most energy.

Answer
Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Hormones help buds form and grow in the winter.
Explanation:
Auxins exert various effects including elongation growth. The basic effect of auxin involves regulation of stem growth. This occurs by stimulation of cell growth in the direction of elongation.Auxin inhibits the growth of axillary buds.
Answer:
This planet contains an atmosphere and ocean, so it would be A im guessing.
