Answer:
The correct answer is: Hydrophobic, Hydrophobic.
Explanation:
- Proteins are made up of polypeptide chains which are formed by the polymerization of amino acid molecules, linked together by peptide bonds.
- The amino acids can be broadly classified into non-polar and polar.
- The non-polar amino acids can be defined as those amino acids whose side chains possess hydrocarbon molecules only. They do not possess any charge and are incapable of forming hydrogen bonds with water molecules. They tend to avoid water and so they tend to remain buried into the interior of a protein. Examples can be illustrated as Leucine, Valine, Isoleucine, Phenylalanine, etc.
- The polar amino acids can be defined as those amino acids whose side chains either possess a charge (positive or negative) or a hydroxyl group which is capable of forming hydrogen bonds with water molecules. As they tend to form hydrogen bonds with water molecules they are usually found on the surface of the proteins. Examples can be illustrated as Lysine, Arginine, Serine, Asparagine, etc.

The use of skin graft is necessary for a number of reasons. Some treatments use this procedure temporarily, just to prevent infection or the like, while other treatments use it permanently to replace a completely lost area of the skin.
One of the functions, in both cases, is to protect the area from possible infections.

Answer:
Grow the seedlings of oats for Avena coleoptile test in a petri plate and let them germinate in light, so that the coleoptile forms with leaves.Cut the coleoptile stem and add agar block of auxin with different concentrations in all different oat seedlings and expose them to sunlight.Then observe the amount of bending of coleoptile stem towards the light in different samples added with different amount of auxin in the agar slab.
