Answer: Ribosomes are the sites in a cell in which protein synthesis takes place.
Explanation: Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins. For example, rapidly growing cells usually have a large number of ribosomes
Anabolic steroids are synthetic forms of the male hormone testosterone that are used to cause muscle hypertrophy.
It is properly knowns as anabolic-androgenic steroids (AAS). They are anabolic in nature and increases the protein found within the cells especially in the skeletal muscles. It also has varying degrees of androgenic and virilizing effect which includes inducing the development and maintenance of male secondary sexual characteristics such as facial and hair body growth.
In the 1930s AAS were synthesized and are recently used as a therapeutic medicine to stimulate muscle growth, increase appetite, induce puberty in males and treat wasting conditions among cancer and AIDS patients. It was also acknowledged by the American College of Sports Medicine that AAS, when joined with an adequate diet, can contribute to increasing the body weight, often as lean mass increases and the gains in muscular strength are achieved by doing high-intensity workout and proper diet.
The correct answer is: A. The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell and the cytoplasm, which is a water-like environment. The hydrophobic tails form an oily layer inside the membrane that keeps water out of the cell.
Plasma membrane of the cell is arranged in a bilayer of phospholipids. Phospholipids are amphipathic molecules which means that they have both hydrophilic and hydrophobic regions. The hydrophilic heads of phospholipids that are faced outward and hydrophobic layer located in the interior of the bilayer together make a good barrier between the interior and exterior of the cell, so the water and other polar or charged substances cannot easily cross the hydrophobic core of the membrane.
The answer is A
