Answer/Explanation:

All cells are not the same because not all cells contain membrane-bound organelles.

Prokaryotic cells lack membrane-bound organelles. In contrast, eukaryotic cells contain membrane-bound organelles like an endoplasmic reticulum, lysosomes, and importantly, a nucleus.

The nucleus is where genetic information (DNA) is stored. However, it is only present in eukaryotic cells. Prokaryotic cells do not possess a nucleus, the DNA is found in the cytoplasm.

Individuals without AFS have a glutamic acid at position 487 on the ALDH2 protein, whereas individuals with AFS have a lysine at
azamat

Answer:

Aldehyde Dehydrogenase 2 (ALDH2) is an enzyme required to eliminate toxins such as acetaldehyde and alcohol, thereby mutations in this protein may be associated with the Alcohol flush syndrome (AFS)

Explanation:

ALDH2 is a protein required for ATP generation by catalyzing the oxidation of aldehydes to carboxylic acids (i.e., oxidation of NADH to NAD+). Mutations in the ALDH2 gene have been associated with the inactive form of this enzyme, and this specific mutation at position 487 alters its enzymatic activity associated with the metabolism of acetaldehyde and alcohol. This amino acid substitution may lead to the active site-directed inactivation of the enzyme.

What are two ways in which the value of soil can be reduced?
Dovator [93]

Fertile soil is valuable because there is a limited supply. Less than one eighth of land on Earth has soil that are well suited for farming.

The thick, fertile soil of the prairies took many thousands of years to develop.

The two ways that the value of soil can be reduced is help use soil correctly, peanuts were once a corp to help soil, and still can be. The soil value recycle rocks and bedrock.

The value of soil is reduced when it loses its fertility and when topsoil is lost due to erosion. Soil can be conserved through contour plowing, conservation plowing and crop rotation. The thick mass of tough roots at the surface of the soil.
