Biology 111 Chapters Exam Questions with Latest Update

How does biology unify much of natural science? - ANSWER-Biology unifies much of natural science by incorporating elements of natural sciences. Energy exchanges associated with physics are used in every level of exchange between living organisms. Chemical elements from chemistry make up the structure of living things. Biology builds on already known information by exploring the wonders of life. What are the seven characteristics of life? - ANSWER-1) Cellular organization 2) Ordered complexity 3) Sensitivity 4) Growth, development, and reproduction 5) Energy utilization 6) Homeostasis 7) Evolutionary adaptation Describe cellular organization. - ANSWER-All organisms consist of one or more cells. Cells carry out the basic activities of living. Each cell is bound by a membrane that separates itself from its surroundings. Describe ordered complexity. - ANSWER-All living things are both complex and highly ordered. The body is composed of many different kinds of cells, each with their own function. Describe sensitivity. - ANSWER-All organisms respond to stimuli. Examples include plants growing toward light and eyes dilating when in the dark. Describe growth, development, and reproduction. - ANSWER-All organisms are capable of growing, reproducing, and they all possess hereditary molecules that are passed to their offspring, ensuring the offspring are of the same species. Describe energy utilization. - ANSWER-All organisms take in energy and use it to perform many kinds of work. Every muscle in the body is powered with energy obtained from diet. Describe homeostasis. - ANSWER-All organisms maintain relatively constant internal conditions that are different from their environment. For example, internal body temperature stays the same despite the weather outside. Describe evolutionary adaptation. - ANSWER-All organisms interact with other organisms and the nonliving environment in ways that influence their survival, and as a consequence, organisms evolve adaptions to their environment.
