<span>Although they are both striated muscles, that is the biggest thing they have in common. The skeletal muscle is controlled by the somatic nervous system, while the cardiac muscle is not. In fact, it is involuntary, therefore without a control center. Another difference is where they are located in the body.</span>
<span>Protein tertiary structures
are known to be a three dimensional structure of a protein with a single
polypeptide chain (backbone) and one or more protein secondary structures known as
protein domains.</span>
Tertiary Structure Interactions
1) Hydrophobic Interactions: they are non-
covalent bonds and very important in the formation of tertiary structure.
2) Ionic Bonds: the interaction of both positive
and negative amino acids forms a bond that helps to stabilize the protein molecules.
3) Hydrogen Bonds: this bond exit between the
amino acid with hydrophilic side chain found on the surface of the molecules and
water molecules in a solution.
4) Disulfide Bridges: it is a strong covalent bond commonly found between cysteine residues in close proximity space.
Answer:
1. 1/2
2. 1/2
3. 1/4
Explanation:
Let the allele for freckles be A or a while that of dimples be B or b.
A person without freckles but heterozygous for dimples = aaBb
A person who has freckles (whose mother has no freckles) but no dimples = Aabb
aaBb x Aabb
Offspring
4 AaBb - freckled and dimpled
4 Aabb - freckled and non dimpled
4 aaBb - non freckled and dimpled
4 aabb - non freckled and non dimpled
1. <em>Probability that the parents will have a dimpled child</em> = 8/16 or 1/2
2. <em>Probability that they will have a child with freckles</em> = 8/16 or 1/2
3. <em>Probability that they will have a child with freckles and dimples</em> = 4/16 or 1/4
