Answer:

<em>Diffusion</em>:

Substances, such as water, ions, and molecules needed for cellular processes, can enter and leave cells by a passive process such as diffusion.Diffusion is a type of substance movement that requires no energy to be expended for the substance to move. Simple diffusion occurs when there is no obstacle to the substance so it can diffuse freely.

<em>Osmosis</em>:

Osmosis is the movement of a solvent across a semipermeable membrane toward a higher concentration of solute (lower concentration of solvent).There are three types of solutions that's determine osmosis-

1) hypotonic solution: in this case the solvent is less and the solution is more(dilute solution).More water is there outside the cell than inside the ell, so the water moves into the cell which causes the cell to swell up

2)hypertonic solution: in this case there is more solute than solvent(concentrated). More water is there inside the cell than outside the cell, so more water will leave the cell than it enters as a result the cell will shrink.

3) Isotonic solution: the amount of water inside the cell is equal to water outside the cell as a result the cell will neither shrink not swell.

<em>Examples of diffusion</em>:

Oxygen and carbon dioxide, dissolved in water, are exchanged by diffusion in the lungs: oxygen moves down a concentration gradient from the air in the alveoli to the blood. carbon dioxide moves down a concentration gradient from the blood to the air in the alveoli.

<em>Examples of osmosis:</em>

Osmosis occurs to recover water from waste material. Kidney dialysis is an example of osmosis. In this process, the dialyzer removes waste products from a patient's blood through a dialyzing membrane(acts as a semi-permeable membrane) and passes them into the dialysis solution tank.

Which of the following is NOT one of the Nervous System Functions?. Single choice.
Neko [114]

Answer:

4. Absorb extra fluid between the cells

Explanation:

The nervous system (SN) is a complex system that acts to receive sensory information through nerves, transmit this information via the spinal cord and finally process it in the brain. The SN has three main roles: sensory input, processing and motor output. The SN can be divided into the central nervous system (composed of the brain and spinal cord), and the peripheral nervous system (composed of those nerves located outside the brain and spinal cord). Moreover, the extracellular fluid between the cells comprises four types of fluids: 1-intravascular fluid (blood), 2-interstitial fluid, 3--transcellular fluid and 4-cerebrospinal fluid. The excess of these fluids is absorbed by the capillaries of the lymphatic system.
