Animal behavior researchers often refer to an activity associated with punishment or reward as an operant. The basis for training animals is the operant conditioning. It is a learning process where the animal would learn base from its behavior as it responds to its environment. In this type of learning, the behavior is either increased or decreased by the results that follows the action. It uses rewards and punishments in order to associate with the behavior. For instance, you are trying to teach your dog to fetch an object, if he succeeds in fetching the object, then you give your dog a treat. The dog would think that what it is doing is good and that it would get a reward from it so it would start learning the behavior.
They make proteins, synthesis of proteins
Weight is basically the heaviness of a person or thing.
<span>Prokaryotes have magnetite-containing structures, nucleoid (their version of a nucleus), fimbriae.
Animals have lysosomes.
Plant cells have chloroplasts (make the plant cells green, produce energy for plants), photosynthetic membranes (produce energy for plants), cell well.
Flagella can be found in prokaryotes and animal cells but for a simpler biology class, I would put it with prokaryotes.</span>
