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.
When warmed by the sun, water on the surface of oceans and freshwater bodies evaporates, forming a vapor. Water vapor rises into the atmosphere, where it condenses, forming clouds. It then falls back to the ground as precipitation. Moisture can also enter the atmosphere directly from ice or snow.
I'm pretty sure that it is polarity I hope I am right and good luck, but I am pretty sure it's polarity
Answer:
The correct answer is option C. up-regulation.
Explanation:
When the body requires the increased level of the hormone, target cells increase the synthesis of more receptors on the cell surface of the target organ. This process is known as the up-regulation of the receptors for the hormone.
Up-regulation is an increase in the receptors present on the cell surface of target cells so that cells can easily bind to the hormone. Up-regulation makes the cells increase the sensitivity to a hormone.
Thus, the correct answer is option C up-regulation.
Sorry but there is no image lol
