by Sandi Ackerman. .A rabbit's diet should be made up of good quality pellets, fresh hay, (alfalfa, timothy or oat), water, and fresh vegetables. Anything beyond that is a treat and should be given in limited quantities. Pellets should be fresh, and should be relatively high in fiber (18% minimum fiber).
Supplement. In scientific experiments, the use of controls allows to study one variable or factor at a time. It is, however, important that both the control and other (experimental) group(s) are exposed to the same conditions apart from the one variable under study.
In an experiment, the independent variable is altered, and the effect observed is the dependent variable, or outcome. The controlled variable is intended to be kept the same t â¦ hroughout the experiment so that changes in it do not affect the results. 2 people found this useful. Answered.
