It is the proteins present underneath the cells of the biceps brachii, which slide past each other lengthwise, thus shortening the muscle.
The biceps crosses both the elbow and shoulder joints, its prime role is at the elbow where it flexes the forearm and supinates the forearm. The biceps brachii refers to a bi-articular muscle, that is, it assists in monitoring the movement of two different joints, the elbow, and the shoulder.
<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.
<span>Variations in asexual organisms are rather rare since they occur as a result of mistake of mitosis during DNA copying. On the other hand, variations in sexual organisms are a result of fusion of two different gametes that carry different traits. Thus, the offspring carries characteristics of both parents, resulting in greater genetic variation within the next generation. Consequently, sexual organism obtain greater genetic variation than asexuallt reproducing species.</span>
The majority of mutations have neither negative nor positive effects on the organism in which they occur.
Answer:
Mutation rate is not a difference between a population showing exponential growth and a population showing logistic growth. Hope this helped :D
