Biology

polet [3.4K]3 years ago
4 0

Answer:

Stephen Stearns states that natural selection doesn't mean the survival of the fittest organisms, but rather this mechanism is illustrated by the selective reproduction of the fittest. Natural selection can be classified into distinct types, including directional, disruptive and stabilizing selection, which are in turn based on sexual selection. These types of selection are driven by different outcomes that have different dynamics.

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.

Why is it important that scientists haven’t identified a Lokiarchaeota cell yet?
WARRIOR [948]
It's important because we need the scientists to discover where it is. The Lokiarchaeota is a main cause for infections, and diseases, and if we identify it, and study it, we may know how to cure certain diseases, and how to prevent them.
