Division of labor is essentially when tasks are divided and carried out by specific parts. This occurs in cells, where different tasks are distributed among different parts, referred to as the organelles. For example, the mitochondria in the cell produce energy to carry out cellular activities. The nucleus is involved in cellular division and other genetic functions. In such a manner, the "labor" that a cell has to perform is divided among its organelles.
The answer that makes the most sense is number one or two. Number 3 and number four both makes no sense in that context. Most of the time an animal will not die or mutate due to a parasite in its body.
G0 phase cells
The mitotic cycle of somatic, or body, cells is responsible for the production of copies of those cells. The mitotic cycle has different phases, each of which involves a different set of physiological changes to the cell. The G0 phase is described as the resting phase of a cell, where no activities relating to cell division are taking place. G0 phase cells remain in this phase their entire lives, so they do not divide. Another example of such a cell is found in red blood cells.
It causes soil pore spaces to become smaller, and it reduces water infiltration rate into soil, and decreases the rate that water will penetrate into the soil root zone and subsoil.
Cancer is the disease that results in uncontrolled cell growth.
