Answer:
Differences in their boiling points
Explanation:
When crude oil is distilled and separated into categories, the categories are characterized by the differences in their boiling points.
At different boiling points, each of the fraction will separate out.
- Crude oil is made up of different fractions of hydrocarbons.
- As the chain length of the hydrocarbon increases, the volatility reduces and boiling point increases.
- Components with short carbon lengths rises out from the column first and are cooled and extracted.
- The categories are thereby, classified based on differences in their boiling points.

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.
