Soil aeration is caused by CHANGE IN PRESSURE ASSOCIATED WITH WEATHER EVENTS.
Soil aeration is the process of rapid exchange of oxygen and carbon dioxide between the pores in the soil and the atmosphere. The movement of air through the soil is dependent on the change in pressure associated with weather events; the change in pressure enable the soil to release gas to the outside when low pressure system pass over and to take in air when high pressure returns. <span />
A mitotic inhibitor chemotherapy drug would cause the DNA to break during the early stages of cell division. Mitotic inhibitors are drugs derived from natural plant sources, and work by inhibiting cell division or mitosis, where a single cell divides into two genetically identical daughter cells. They may bind to tubulin and inhibit its polemerization into microtubules.

Sperm cells inside the pollen grain travel down the pollen tube and into the ovary which contains the ovules. Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule
Convergent evolution in my understanding is the independent evolution of similar features in species of different lineages.
