Artemon [7]

Answer:B). Cell membranes are composed of a lipid bilayer.

Explanation: A membrane is a lipid bilayer that surrounds the cell. Lipids have two parts: the fatty acid chain (the tail) and the phosphate group (the head).

The phosphate head groups are polar, face outward and interact with the outside environment of the cell. The fatty acid chain is hydrophobic and nonpolar, face each other in the bilayer thus forming a hydrophobic fluid interior.

The hydrophobic nature of the bilayer interior makes the membrane to permit only nonpolar and hydrophobic molecules to pass through the cell membrane. This is the reason the membrane allows only molecules that dissolve in the lipid bilayer to pass through to enter or leave the cell.

Which is a dominant genetic disorder?
ikadub [295]

Answer:

<em>The correct option is A) achondroplasia</em>

Explanation:

Achondroplasia is a genetic disorder which is caused in an autosomal dominant pattern. This means that an individual who even has a single allele for the gene will have the disorder. This is because a dominant allele masks the effect of the recessive allele.

Achondroplasia is a disorder in which the cartilage of the long bones of the arms and legs does not get converted into bones. It is a type of dwarfism.
