Mechanisms of evolution correspond to violations of different Hardy-Weinberg assumptions. They are: mutation, non-random mating, gene flow, finite population size (genetic drift), and natural selection.
Answer:
8 electrons
Explanation:
This gives each hydrogen atom two electrons in its outer energy level, which is full. It also gives oxygen 8 electrons in its outer energy level, which is also full.

Cancer cells are less likely than normal cells to undergo _apoptosis______, or programmed cell death.
Apoptosis is synonymous to programmed cell death
Explanation:
Programed cells death of the cell is required to maintain proper tissue homeostasis. Examples of when apoptosis is necessary are when a cell may have errors in its DNA replication process. Apoptosis ensures the cell does not continue dividing and generating cells with the error. Other forms of damage to a cell that is hard to repair also require that the cell undergo apoptosis.
In cancer cells, apoptosis pathway faulted and even when cells are required to undergo programmed cell death, such as in the case when lethal mutations occur, the cell continues to divide creating many cells that have the defect. This is what creates cancer tumors,
