An increase in the greenhouse effect causes an increase in___
andriy [413]

The answer is option B "temperature." Greenhouse effect is the process of trapping the suns heat in the lower atmosphere. A increase of greenhouse effect would cause surface temperatures to rise.  Which then contributes to global warming because of melting the ice bergs in cooler areas on Earth and causing waters to rise and creating storms. It's not option A because the sun gives off heat or harmful radiant waves which doesn't increase carbon dioxide levels. Wouldn't be option D because it would contribute but it wouldn't happen without a increase of temperature. It also wouldn't be option C because oxygen isn't relevant in this case.

Hope this helps.

Which of the following is the best definition of a saturated fatty acid?
Oksi-84 [34.3K]
The best choice would be C.

A saturated fatty acid is a basic unit of lipid that consists of only single carbon to carbon bonds.

Saturated fatty acids have been “saturated” with hydrogen ions and only have single carbon to carbon bonds, unlike unsaturated fatty acids that have both single and double bonds and have kinks and aren’t straight.

Saturated fatty acids are solid in room temperature(animal fats) and unsaturated fatty acids are liquid in room temperature(oils/plant fats).

If a person is normovolemic and consumes a large quantity of a hyperosmotic solution, it will ________. If a person is normovole
Irina-Kira [14]

Answer:

cause cells to shrink due to an increase in the osmolarity of extracellular fluid.

Explanation:

Normovolemic describes the situation in which a living organism maintains a normal volume or amount of blood in the body.

A hyperosmotic solution can be defined as a solution having an increased level of osmotic pressure. Thus, when there's a greater amount of solute with respect to another solution in a membrane with close similarities, it is known as hyperosmotic solution.

Basically, hyperosmotic solution gives rise to higher difference between solutes and similar solutions.

Hence, when a normovolemic person consumes a large quantity of a hyperosmotic solution, it will cause cells to shrink due to an increase in the osmolarity of extracellular fluid i.e the total number of solute particles with respect to the concentration of a solution (Osm/L).
