The structures that are in the body are In a complex environment, animals learn from their responses to stimuli and events. Appropriate response to reward and punishment can promote survival, reproduction and increase evolutionary fitness.
Answer:
An enzyme refers to a kind of protein found inside a cell. The enzymes result in the chemical reactions within the body. The function to accelerate the rate of chemical reaction in order to support life. The enzymes in the body assist in performing very essential functions. These comprise eradicating toxins, building muscle, and dissociating particles of food at the time of digestion.
Enzymes are needed for performing the proper function of the digestive system. Digestive enzymes are primarily produced in the stomach, pancreas, and small intestine. However, even salivary glands generate digestive enzymes in order to dissociate the molecules of food at the time of chewing.
There are three prime kinds of digestive enzymes, which are classified on the basis of the reactions they catalyze. These are protease, amylase, and lipase.
The group in which a star is classified according to its spectrum, especially using the Harvard classification.
Because if we're simultaneously moving/manipulating two different variables it can be very hard to determine why one variable is changing and why the other is changing. While this can be done with more complicated experimental designs, it usually is the case that scientists will only manipulate one variable and not two different ones.
