Answer: b. through the stomach

Explanation:

A drug is a substance which is capable of bringing the physical and physiological change in an organism when taken either orally, intravenously, subcutaneously, smoked or inhaled.

The drug which is taken orally or ingested enters the elementary canal. It is dissolved inside by the fluids in stomach, then absorbed by the bloodstream through the linings of the stomach and later by the intestine.

Active Immunity is natural.

Passive Immunity is maternal.

Active Immunity from Vaccination.

Passive Immunity is Artificial.

Passive Immunity:

Does not require previous exposure to a disease agent

Takes effect immediately

Does not last long (up to a few months)

Active Immunity is produced inside of the body, whereas passive immunity is introduced from outside of the body.

Active Immunity is from direct infection and vaccination.

Passive Immunity is from Breast milk, Injection, Mother to baby through the placenta.

Active Immunity takes effect over time (typically several weeks).

Passive Immunity takes effect immediately.

Active Immunity's length of efficacy is Long-term to lifelong.

Passive Immunity is short-term.

Active Immunity is produced by memory cells, Passive Immunity is not.

Hope this was insightful and enough information.

The atoms found in living tissues all have complete outer electron shells and are therefore quite stable on their own.

What would be the best explanation for why myelinated fibers conduct signals faster than unmyelinated fibers?

Sliva [168]

Answer: The diffusion of ions along the axoplasm is faster,in myelinated compare to unmyelinated,

Neurons are the structural and functioning units of nervous system.They are the vehicles for transmission of impulses as electrical signals from one part of the cells,and from one part of the body to another.

The basic structural components of a typical neuron are the cellbody, the axon, and the dendrites.

Based on structure neurons are classified as myelinated and unmyelinated.This is based on the the surrounding layer of myelin sheath around the axon. The myelin provides the insulating layer for the axon.And ensures fast movement of impluses.

In myelinated neurons the myelin sheath are interrupted at intervals by gaps along the length of the axon called Nodes of Ranvier. These gaps contains more Na-K channels for influx and out-flux of K and Na+ ions for transmission of impulses.

The cytoplasm of axon is called axoplasm,Since this is surrounded by myelin sheath which contains Na-K+ channels,The rate of diffusion of ions along these channels is faster for depolarization to take place than in unmyelinated neurons. Inaddtion as these ions diffusion increases,its jump faster at the nodes of Ranvier (saltatory conduction) to the next axoplasm which further speed up the rate of transmission.

Unmyeinated lacks myelin sheath,therefore the exchange and the rate of diffusion of ions along the axons is low.
