Which statement correctly describes amphipathic (or amphiphilic) helices and sheets?Helices are typically hydrophilic on one sur

face, whereas sheets usually have both hydrophilic and hydrophobic residues evenly distributed throughout their structure.Sheets are typically hydrophilic on one surface, whereas helices usually have both hydrophilic and hydrophobic residues evenly distributed throughout their structure.Amphipathic helices and sheets have hydrophilic and hydrophobic residues evenly distributed throughout their structure.Amphipathic helices and sheets have predominantly hydrophilic (or hydrophobic) residues on one face.

Answer:

The correct answer is the last statement.

Explanation:

Amphipathic refers to a substance that comprises both hydrophobic and hydrophilic surfaces. Thus, the given first three statements are incorrect. The amphipathic helices are witnessed on the proteins surfaces in which the hydrophilic region associates with the aqueous phase and the hydrophobic regions associate with the hydrophobic component of the protein.  

Both the amphipathic sheets and helices exhibit primarily the hydrophobic or hydrophilic residues on one face. Thus, the correct answer is the last statement.

If you used a slingshot to launch a bowling ball and a baseball with the same force, which would go further? Explain your reason
Alex Ar [27]

Answer: The baseball will go farther because of Newton's law. The more mass an object as, the more force needed to move it. The bowling ball has more mass than a baseball so more force is needed to move it.

Sickle-cell trait is caused by a single defective allele, but sickle-cell disease only occurs in individuals that are homozygous
Pavel [41]

Answer:

6,25%

Explanation:

Considering that the couple has a trait of sickle cell anemia, we know that both are heterozygous for the disease (Aa) and therefore can have children with the following genotypes:

Parents: Aa X Aa

Children: AA(A x A), Aa(A x a), Aa (a x A) and aa(a x a)

Knowing that sickle cell anemia only occurs in homozygous individuals, the probability for children to have the disease according to each crossing is:

A x A = 1/4 = 25%

A x a = 1/4 = 25%

a x A = 1/4 = 25%

a x a = 1/4 = 25%

The probability of forming each homozygous child (aa) is 1/4 or 25%. Since they are two children, the probability of both having sickle cell anemia is calculated by multiplying the probability of each, so:

1/4 × 1/4 = 1/16 = 0.0625 = 6.25%

It is concluded that the probability of a heterozygous couple for sickle cell anemia to have two children with the disease is 6.25%.
