Although seemingly diverse, living things, or organisms, share certain essential characteristics. The most recent classification system agreed upon by the scientific community places all living things intosix kingdoms of life, ranging from the simplest bacteria to modern-day human beings. With recent in...
Living things need food to grow, they move, respire, reproduce, excrete wastes from the body, respond to stimuli in the environment and have a definite life span. Water, sun, moon and stars do not show any of the above characteristics of living things. Hence, they arenon-living things. ...
Which of the following statements does not describe a characteristic of living organisms? a) All living organisms require energy. b) Living organisms can reproduce. c) All living organisms can sense their environment and respond to it. d) All living organ ...
