A positive charge is created in the cell that travels down it does a nerve

impulse begin in a neuron. Thus, the correct option is A.

<h3>How the neuron get stimulus?</h3>

When a neuron receives a chemical stimulation, a nerve impulse is formed. The electrical action potential of the nerve impulse passes along the axon membrane to the axon terminal. Neurotransmitters are released at the axon terminal, which transfer the nerve impulse to the next cell.

The resting potential of a neuron is the electrical differential across its membrane. The sodium-potassium pump, a transport protein, creates the resting potential. This protein generates a positive charge by moving a high number of sodium ions (Na+) outside the cell.

explain it to the class.

Explanation:

<h3>ANSWERS :</h3>

1- C ( this is an assumption; a hypothesis is always based on an assumption.

2- F ( this states to share the results with other classmates).

3- D (this is a description of an experiment you could conduct; you test a hypothesis (usually) by conducting an experiment.

4- A (this is something you could observe during the experiment, therefore it is an observation).

5- E (this sentence is a conclusion).

6- B (This is an actual question)

sladkih [1.3K]

Answer:

Viruses have to invade the body of a host organism in order to replicate their particles. Therefore, most viruses are pathogenic. The main difference between bacteria and virus is that bacteria are living cells, reproducing independently and viruses are nonliving particles, requiring a host cell for their replication.

What body part breaks down lipids

Yanka [14]

The digestion of certain fats begins in the mouth, where short-chain lipids break down into diglycerides because of lingual lipase. The fat present in the small intestine stimulates the release of lipase from the pancreas, and bile from the liver enables the breakdown of fats into fatty acids.
