Nine amino acids are needed to travel through the thickness of the membrane.
Alpha-axial helix's distance between amino acids is 1.5. A
The number of gaps between the 22 amino acids in the helix is equal to (22-1) = 21.
Therefore, the helix's length is (21 X 1.5) = 31.5.
One alpha helix is sufficient to span the membrane's breadth, hence the formula is: span of the helix = thickness of the membrane = 31.5 A
The thickness of the membrane is determined by the formula above to be 31.5 AA.
In the beta-strand, there is 3.5 AA between each amino acid.
Therefore, (31.5/3.5) = 9 amino acids are needed.

Answer:
Identical Twins
Identical twins share all of their genes and are always of the same sex. In contrast, fraternal, or dizygotic, twins result from the fertilization of two separate eggs during the same pregnancy. They share half of their genes, just like any other siblings.
The change that would decrease the pH of a base in a solution at equilibrium is : ( C ) Decreasing the concentration of OH⁻ ions
A base in a solution provides ( OH⁻ ions ) while an acids produces H⁺ ions. therefore an acidic solution ( solution with a lower pH level ) has more H⁺ ions and a decrease in OH⁻ will lead to a corresponding increase in H⁺ ions. so when the concentration of OH⁻ ions is reduced the pH of the base in the solution will be reduced
Hence we can conclude that in order to decrease the pH of a base in a solution at equilibrium decreasing the concentration of OH⁻ ions will help decrease the pH level of the base .

Answer:
Explanation:
a car does not have the ability to reproduce, or maintain homeostasis. Unlike all living things
Answer:
Producers make their own food for energy. The consumers eat the producers and help populations from getting too big. When the consumers die, decomposers break down dead organisms and waste into materials that can be used again
