True or false? leaves appear green because they absorb green wavelengths of light.

1 answer:

7 0

This statement is false. This is because the green light isn't absorbed. The leaves appear green because the chlorophyll of the leaves, the part that makes food, reflects the green light, which has a medium wave length. While reflecting green light waves, it simultaneously absorbs red waves (long waves) and blue waves (short waves)

Snezhnost [94]

Answer:

The rough endoplasmic reticulum

Explanation:

The rough endoplasmic reticulum (ER) is an organelle that has the main function of producing proteins for the cell.

Antibodies are a type of protein, so they are made by the ER.

Since the immune cell can rapidly produce antibodies, it must have a significant amount of rough ER to make the proteins.

When alcohol intake exceeds the body's ability to metabolize it, excess alcohol __________.

katen-ka-za [31]

Answer:

becomes accumulated in the blood

Explanation:

The processing of alcohol is constant in every individual. The rate at which alcohol stays in someone's body is determined by how much of it is consumed.

Alcohol enters the digestive system once ingested and travels to the stomach and small intestines. The amount of alcohol absorbed in the small intestine enters directly to the bloodstream. Once in the blood, alcohol is circulated with it. The liver is responsible for the metabolic elimination of most (about 95%) of ingested alcohol from the body. If an individual consumes more than this, the system becomes saturated, and the additional alcohol will accumulate in the blood and other tissues until it can be metabolized. If this happens frequently or too fast, damage to the brain and tissues of the body can occur.

Blood Alcohol Concentration (BAC) depends on the amount of alcohol consumed and the rate at which the individual's body metabolizes alcohol. Because the metabolism of alcohol by the body is constant, taking in alcohol at a rate higher than the rate of metabolizing it results in a cumulative effect and increase in the blood alcohol concentration.

It is important to note that, the more one drinks the longer alcohol stays in the system.
