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.

Between ________ degrees fahrenheit, bacteria will multiply the most rapidly.
Damm [24]

Bacteria will multiply so fast between 41-135 degrees Fahrenheit. Bacteria can grow rapidly in the TDZ, also known as the Temperature Danger Zone, which is 41f - 140f. Generally 37 degrees - body temperature. However some, such as fungi, prefer lower temperatures as they are found on the outside of the body. Similar some bacteria.

The symptoms of tetanus are caused by the neurotoxin ________.
seropon [69]

Answer:

The correct answer is the neurotoxin known as tetanospasmin toxin.

Explanation:

Tetanus is a disease caused by a bacteria known as clostridium. The bacteria are found in soil, manure, dust, and saliva. It can enter the host body by a cut or rusted or dusty nail or burn. It causes muscle spasm or jaw locking or bone locking.

It releases the neurotoxin that is tetanospasmin toxin that inhibits the secretion of γ-aminobutyric acid (GABA) and results in a variety of symptoms associated with tetanus.

Thus, the correct answer is the neurotoxin known as tetanospasmin toxin.
