When cells make protein from amino-acids, they require energy from ATP. It is also necessary to use ATP to link glucose molecules together to form starch or glycogen. Mitochondria: 1  have a double membrane the inner membrane. 2  the outer membrane; 3  have their own DNA this carries the information to make the enzymes;
In this technique, each member of the population has an equal chance of being selected as subject. The entire process of sampling is done in a single step with each subject selected independently of the other members of the population. There are many methods to proceed with simple random sampling. The most primitive and mechanical would be the lottery method. Each member of the population is assigned a unique number.
Probability Sampling. A probability sampling method is any method of sampling that utilizes some form of random selection. In order to have a random selection method, you must set up some process or procedure that assures that the different units in your population have equal probabilities of being chosen.
