Answer:
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.
The earth is made up of many interacting system which are quite dynamic in nature. The earth is sub divided into four components which are THE ATMOSPHERE, THE HYDROSPHERE, THE BIOSPHERE AND THE GEOSPHERE. These are the separate systems that made up the earth system.
The hydrosphere is make up of all the water components on the earth surface and how the water cycle through nature. The atmosphere refers to the layers of gases that surround the planet earth while the biosphere refers to the living components on the earth surface. All these systems interact together to keep life existing on earth.
Answer:
Cold weather triggers the underfur to grow each winter.
Explanation:
this is because they would freeze in the cold water in the winter.
Answer:
The answer is the accessory nerve.
Explanation:
We have 12 pairs of cranial nerves, the accessory nerve is the XI pair. This is responsible for the innervation of the sternocleidomastoid and trapezius muscles.
The fibers of the accessory nerve originate from neurons that are located in the upper spinal cord. These fibers join together forming roots and once the nerve is constituted, it enters the skull through the great hole that is located at the base of the skull.
Then, the nerve continues its path along the inside of the skull in the direction of the jugular hole and then leaves the skull next to the glossopharyngeal nerve (IX) and the vagus (X).
Thus, the accessory nerve enters and leaves the skull again, characterized by being the only cranial nerve which has this behavior.
