Answer:

D) Radioactive sulfur.

Explanation:

The process begins by labelling the yeast with the radioactive sulfur and then it is incorporated into the peptides. Then the scientists can detect and isolate small portions of it.

Radioactive sulfur is preferred  for this process because it is short-lived.

What movement of the thumb would be most affected by lesion of the median nerve in the cubital fossa
natka813 [3]

Answer:

flexion

Explanation:

The flexion is a movement of the body part that is described the bending of an elbow, or the clenching a hand into a fist, etc. where the angle between any segment of the body and its proximal segment decreases.

In simple words, the flexion is a movement which decreases the angle between two body parts when they are moved.

The flexion occurs in the sagittal plane.

Thus, the movement of a thumb that would be mostly affected by the lesion of median nerve in cubital fossa is the flexion movement.

the r group or side chain of the amino acid glutamic acid is hydrophilic. The R group of the amino acid valine is hydrophobic. w
boyakko [2]

Answer:

You would expect to find glutamic acid on the fringes of the three-dimensional protein structure while valine would be found mostly inside the protein structure.

This is because hydrophilic molecules are ‘water-loving’ because they carry a charge and can, therefore, interact ‘positively’ with water by forming hydrogen bonds with the polar water molecules. Hydrophobic molecules on the other hand are water-hating. They carry no charge hence have no way of ‘positively’ interacting with the polar water molecules.

Remember the structure of the cell membrane too? The negatively-charged phosphate ends of the phospholipid bi-layer sandwich the non-polar fatty acid chains because they don't ‘like’ interacting with water. This applies to the same principle.
