Answer:

A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.

It uses a reflex arc because a reflex controls the brain and makes you think quick to do a fast movement that is known as a reflex, a example is something falling and your instinct is to catch it.

b- amino acids

c- eicosanoids

d- carbohydrates

Answer:

Explanation:

Eicosanoids behave like hormones, but they did not desire to move. Eicosanoids sometimes seem on cells nearby to their locality of composition. Eicosanoids also swiftly split down, so they are incapable of progress quite notably. Most eicosanoids are created from arachidonic acid.

Hen, eggs, burgers are samples of meals that render arachidonic acid. The eicosanoids obtained from certain fatty acids possess a diversity of consequences on your body. They also modify the insusceptible rejoinder and several respiratory and generative processes.

Which statement BEST characterizes the general relationship between air pressure and elevation?

Ad libitum [116K]

Both have an inverse relationship.

Explanation:

The two have an inverse relationship, that is, when elevation increases, atmospheric pressure decreases.

This is due to the amount of air on top of you at your current elevation.

At lower elevations, you have more air above you, and thus more pressure.

At higher elevations, you have less air above you, and thus less pressure.

At high elevation food takes longer time too cook due to low pressure, so at high altitude pressure cooker is used to cook food.

OK, :)
