Answer: Option D
Explanation:
Apolipoprotein B is a type of apolipoprotein that bind lipids including cholesterol and forming the main organizing protein in lipoproteins such as in the low density lipoprotein. The low density lipoprotein serves as a vehicle to transport cholesterol into the cell through the receptor mediated endocytosis process. This process allows for the movement of larger molecules from the outside of the cell into the cell. Thus apolipoprotein can bind as ligands to the LDL receptors and allow for the transport of fats into the cell..
A muscle on the front of the upper arm is called the biceps. The "short head" and "long head" of the biceps function as a single muscle.The triceps, also known as triceps brachii, is a large muscle on the back of many vertebrates' upper limbs that is known as the "three-headed muscle of the arm" in Latin. The long head, lateral end, and medial end makeup its three components.
Tendons, which are strong connective structures, hold the biceps to the arm bones. The proximal biceps tendons are the tendons that attach the biceps muscle to the shoulder joint twice. The distal biceps tendon is the tendon that connects the biceps muscle to the forearm bones (radius and ulna). When the biceps muscles contract, the forearm is pulled up and rotated outward.
