with correct answers.
Cell ANS - An organized unit that can survive and reproduce by itself, using energy, necessary raw
materials, and DNA instructions.
homeostasis ANS - A state of overall internal chemical and physical stability that is required for survival
of cells and the body as a whole.
primates ANS - A distinct group of mammals, that includes humans, apes, and their close relatives.
vertebrate ANS - An animal that has a backbone.
biosphere ANS - All parts of the earth's waters, crust, and atmosphere in which organisms live.
control group ANS - In an experiment, a group to which one or more experimental groups can be
compared.
experiment ANS - A test carried out under controlled conditions that the researcher can manipulate.
hypothesis ANS - A proposed explanation for an observation or how a natural process works.
sampling error ANS - Distortion of experimental results, often because the sample size is too small.
