Makovka662 [10]

Answer:

Alanine to lysine.

Explanation:

Mutation may be defined as the sudden, heritable change in the genome sequence of an organism. Two main types of mutation are chromosomal mutation and point mutation.

The mutation has occurred in which the arginine is replaced by alanine. The mutation that can restore to wild type is the conversion of alanine with lysine.    Since both arginine and lysine are basic amino acids. They both shows almost similar function and the replacement of lysine with alanine shows the wild type activity.

Thus, the answer is alanine to lysine.

suter [353]

B) It is a fluid mosaic model, with proteins interspaced in the phospholipids, both of which can freely move laterally.

Explanation:

The fluid mosaic model proposed by Singer and Nicolson describes the plasma membrane’s structure as a mosaic pattern of components consisting of phospholipids, proteins, cholesterol, and carbohydrates; all of which provides the unique fluid character of the membrane.  

According to this model, the phospholipids constitute the main fabric, cholesterol attaches between the phospholipids in between the layers, integral proteins embedded within the bilayers of the phospholipids, peripheral proteins along the peripheries of the layers and carbohydrates outside the membranous layers.
