Ascientist found two different sizes of a same protein obtained from plants and animals. this size difference in same type of protein doing identical function could be due to

Deletion and glycosylation.

Explanation:

Proteins is polymers of the alpha amino acids that are directly linked together through the peptide bond. Proteins plays an important role in the metabolic pathways as most enzymes are made of protein.

The same protein can exist in two different size. This might occur due to the deletion of the particular amino acids sequence in one organism and normal in other organisms. The glycosylation of the same protein at different position in the proteins may also leads to the difference in the protein size.

Thus, the correct answer is deletion and glycosylation.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
