Answer:

Mutualism

Commensalism

Parasitism

Explanation:

In mutualism, both organisms benefit.

<em>Ex</em>. Sea anemone and clownfish. Clownfish gives the anemone food, the anemone allows the clownfish to use it as a home.

In commensalism, one organism benefits, while the other is neither harmed nor benefited.

<em>Ex</em>. Sharks or whales and remora fish. The remora rides along the belly of whales or sharks and when it eats, the pieces that float around, the remora eats the excess.

In parasitism, one organism is benefited, while the other is hurt.

<em>Ex. </em>Dogs and fleas. The fleas are constantly biting and feeding off of the dog's skin. The dog gets bitten and itches a lot.

Mutualism and commensalism are similar because at least one organism is benefited.

Parasitism and commensalism are different because instead of one organism not getting hurt, like in commensalism, that happens in parasitism.

Which of these statements about the human sense of touch is NOT true?
Sladkaya [172]

Answer:

The correct answer is There are very few receptors on the soles of a person's feet.

Explanation:

The skin is made up of a layer called the epidermis. The epidermis contains cells that are very sensitive and are responsible for perceiving everything we touch by sending this information to the brain.

All the nerve endings that our body has are in charge of controlling the sense of touch.

All the sensations that we perceive when touching something with any part of the body are linked to the sense of touch.

The most sensitive places on our body are palms, lips, tongue, soles of the feet, fingertips, eyelids and face.

Therefore the correct answer is There are very few receptors on the soles of a person's feet.
