The pancreas is responsible for the elimination of 95% of ingested alcohol from the body through metabolism.

Answers

Answer:

False

Explanation:

The human body mechanisms try to excrete out the ethanol from the body before it gets circulated in the body through blood. The body does so by converting the ethanol to certain metabolic products which get filtered and excreted out through urine.

The metabolism of alcohol takes place in the liver in two steps- Ethanol is converted to acetaldehyde by the alcohol dehydrogenase enzyme. The acetaldehyde is toxic to cells and is the compound responsible for the hangover after drinking.

The acetaldehyde is then converted to acetic acid by an enzyme called acetaldehyde dehydrogenase. The acetic acid through respiration gets converted to water and carbon dioxide and rest is excreted out through urine.

Thus, the liver is the organ responsible for the metabolism of ethanol and not pancreas.

A population of mice is evenly divided into two groups, and each group is placed on an isolated island with no existing mouse population. Which statement best explains the difference in the mouse populations on Island A and Island B at the end of the 20 years?

Answers

The differences in the mouse populations on Island A and Island B after 20 years will likely be due to genetic drift.

What is genetic drift?

Genetic drift is a mechanism of evolution that refers to random fluctuations in the frequency of alleles (versions of genes) in a population. These fluctuations occur due to chance events such as the random segregation of alleles during meiosis, the random distribution of gametes during fertilization, or the random occurrence of mutations.

Therefore, if the two groups of mice have similar genetic diversity and are placed in isolated environments with no mouse populations, the differences in the mouse populations on Island A and Island B after 20 years will likely be due to genetic drift.

Chemical composition describes? A. The types of atoms that make up a sample of matter B. The arrangement in a sample of matter c. All of the above

Answers

The right answer is A.

Since matter is generally composed of several pure bodies (chemical compounds and simple bodies), the chemical composition of a product furnishes the quantity or proportion of each of the pure substances which compose it; they are generically called components.

For answer B it is rather the definition of a chemical structure, it refers to both its molecular topology, its geometry (molecular geometry or space group for a crystal) and its electronic structure.
C.) All of the above ............
