I think the correct answer from the choices listed above is option B. Keratin is the protein in mammals which shows only a primary and secondary structure. Keratin is a fibrous protein forming the structural constituent of hair, feathers, hoofs, claws and many others.
The connective tissue that surrounds and separates individual skeletal muscle fibers (cells) is called epimysium.
The thick connective tissue that encircles the entire muscle tissue is called the epimysium. Typically, the epimysium is made up of several bundles (fascicles) of muscle fibers. It is a thick coating of wavy, uneven connective tissue that covers the entire muscle and shields it from contact with bones and other muscles. The endomysium and perimysium, as well as other connective tissue wrappings of the muscle, are all continuous with it. It continues with tendons as well, where it thickens and becomes collagenous. On tendons, the epimysium is regular, but it is uneven on muscles.
The layer of perimysium connective tissue separates the bundles from one another. Muscle bundles can include 50 to 300 muscle fibres per bundle, depending on their size.

Answer:
B
Explanation:
Ribosenucleic acid (RNA) and Deoxyribosenucleic acid (DNA) are the two nucleic acids formed from building blocks called nucleotides. Although, they are formed from the same building blocks, but have structural differences.
One of the differences between RNA and DNA is that unlike DNA that is a double-stranded molecule formed by the complementary base pairing of two nitogenous bases (nucleotides), RNA is a single-stranded molecule made up of shorter nucleotides.
Answer: All you have to do is add up all the sides
