Answer:
A protein deficiency causes such diverse symptoms because immune, nervous, and muscle system cells require proteins for structure and regulation.
Proteins are the building blocks of bones, muscles, cartilage, skin, and blood. They also help in transporting oxygen, helps in blood clotting during injuries etc.
Explanation:
1) B- brown; b- red hair
Having brown hair is a dominant trait while red hair is recessive.
If the parents had a red-haired child it means they were carriers of the red hair trait, so their genotype is
Bb
2)Getting their genotypes together would result in the possibilities that you see at the image below.
1/4 = 25% BB - brown
2/4 = 50% Bb brown but carrier
1/4 = 25% bb red hair
Answer: 25%
3) The genotype of the child, as i said before would be
bb. By having both alleles being recessive the child will show red-hair. If it was any other genotype( BB or Bb), the child would have brown hair, like their parents.
Leaves change color due to changes in length of daylight and changes in temperatures, the leaves stop their food-making process. The chlorophyll breaks down, the green color disappears, and the yellow to orange colors become visible and give the leaves part of their fall splendor.

Answer:
b. A + G = C + T
Explanation:
Chargaff's rule states that<em> </em><u>a DNA molecule has the same amount of pyrimidines (T and C) as purines (A and G)</u>.
In the DNA, A pairs with T and G pairs with C. For that reason, the number of A bases has to be the same as the number of T bases, and the number of G has to be the same as the number of C.
