Answer:a,b,c,d
Explanation:
Cell-cell interaction occurs in multicellular organisms. When two cells are in close approximation they form a tight junction which are multiprotein complexes that provide contact between neighboring cells. This tight junction permit calcium and other small molecules to pass through from one cell to another.
Transmembrane protein serves as ion channels for transport of ions between extracellular and intracellular fluid.
Integral proteins are deeply embedded in the bilayers and are attached by hydrophobic bonds. They contribute to the structural stability of the cell.
Carbohydrates are found on the cell surface bindings to proteins to form glycoprotein. This glycoprotein are excellent in providing an immune response, protection of cell and cell-cell recognition.
The pectoral girdle articulates with the axial skeleton only at the Sternoclavicular ligament<span>. The pectoral girdle connects the upper limbs to the axial skeleton and serves as the attachment site for the muscles of the upper back, chest and neck. The clavicle is the only long bone that lies in a horizontal position in the body. it has three regions; the medial end, the lateral end, and the shaft. The medial end has a triangular shape and articulates with the manubrium portion of the sternum. This forms sternoclavicular joint, which is the only bony articulation between the pectoral girdle of the upper limb and the axial skeleton. </span>
Answer: increase life expectancy
It consists of the following six muscles: Piriformis, gemellus superior, obturator internus, gemellus inferior, quadratus femoris and the obturator externus.
