Epithelial cells are mainly used for protection; in the urinary tract, these tissue cells are used to protect the bladder from toxic urine. The tissue can also expand to hold larger quantities of urine.
The correct answer is A. maintaining homeostasis.
Homeostasis is a term referring to an organisms continuous process of maintaining and auto-regulating the conditions of its internal environment. Variables such as pH, temperature, and fluid balance need to be at optimal conditions in order for the organism to function properly.
In this example, the phosphate buffer system permits the organisms to maintain a constant pH in their intracellular fluid. This is one of the organism's homeostatic mechanisms.
The anterior ventral rootlets carry MOTOR NEURONS impulses to the spinal nerves.
The anterior ventral rootlet is the one responsible for carrying motor neurons impulses from the spinal cord to the periphery. The cell bodies of the motor neurons are located in the gray matter of the spinal cord.
The environment that will have a negative impact on both cells with a cell wall and cells without a cell wall is the hypertonic environment.
<h3>What is a cell wall?</h3>
A cell wall is defined as the flexible outer layer of the cell that provides protection for the cell from any physical or chemical stress.
A hypertonic fluid environment is the type of fluid that is highly concentrated than the cell.
Therefore, when a clear is placed in a hypertonic environment, through the process of osmosis, water moves out of the cell.
This affects also cells that do not possess cell wall.
Therefore, the environment that will have a negative impact on both cells with a cell wall and cells without a cell wall is the hypertonic environment.
