Campbell Essential Biology by Eric Simon Jean Dickey Jane Reece Included Study Materials | Correct Answers Included [Ch 1] Biology - answer - The scientific study of life. [Ch 1] What is the smallest unit that can perform all activities required for life? - answer - The cell. [Ch 1] Order - answer - All living things have complex but organized structures. [Ch 1] Regulation - answer - Living organisms regulate their internal conditions to maintain life. [Ch 1] Growth and development - answer - Living organisms grow and develop according to information contained in their DNA. [Ch 1] Energy processing - answer - Organisms obtain and use energy to carry out life's activities. [Ch 1] Response to the environment - answer - Living organisms sense and respond to changes in their surroundings. [Ch 1] Reproduction - answer - Living organisms reproduce their own kind. [Ch 1] Evolutionary adaptation - answer - Populations can change over generations in ways that improve survival and reproduction. [Ch 1] Hypothesis - answer - A testable proposed explanation for an observation. [Ch 1] Scientific theory - answer - A broad explanation supported by a large amount of evidence. [Ch 1] Controlled experiment - answer - An experiment that compares an experimental group with a control group while changing one factor. [Ch 1] Independent variable - answer - The factor deliberately changed by the researcher. [Ch 1] Dependent variable - answer - The factor that is measured in response to the independent variable. [Ch 1] Control group - answer - The group used as a standard for comparison and not exposed to the experimental treatment. [Ch 1] Experimental group - answer - The group exposed to the factor being tested. [Ch 1] Structure and function - answer - Biological structures are shaped in ways that allow them to perform particular functions. [Ch 1] Information flow - answer - DNA contains genetic information that directs cellular activities and can be passed to offspring. [Ch 1] Energy flow through ecosystems - answer - Energy enters ecosystems, usually as sunlight, passes through organisms, and eventually leaves as heat. [Ch 1] Nutrient cycling - answer - Matter such as carbon and nitrogen is recycled through organisms and the environment. [Ch 1] Evolution - answer - Descent with modification; populations change genetically over generations. [Ch 1] Natural selection - answer - Individuals with inherited traits that improve survival or reproduction tend to leave more offspring. [Ch 1] What three conditions are needed for natural selection? - answer - Variation, inheritance of traits, and unequal reproductive success. [Ch 1] Artificial selection - answer - Humans selectively breed organisms for desired inherited traits. [Ch 1] Common ancestry - answer - The idea that different species are related through shared ancestors. [Ch 2] Matter - answer - Anything that occupies space and has mass. [Ch 2] Element - answer - A pure substance that cannot be broken down into simpler substances by ordinary chemical means. [Ch 2] Compound - answer - A substance consisting of two or more different elements combined in a fixed ratio. [Ch 2] Four major elements in living organisms - answer - Carbon, hydrogen, oxygen, and nitrogen. [Ch 2] Atom - answer - The smallest unit of an element that retains the properties of that element. [Ch 2] Proton - answer - A positively charged particle located in the nucleus of an atom. [Ch 2] Neutron - answer - A particle with no electrical charge located in the atomic nucleus. [Ch 2] Electron - answer - A negatively charged particle found outside the atomic nucleus. [Ch 2] Atomic number - answer - The number of protons in an atom's nucleus. [Ch 2] Mass number - answer - The total number of protons plus neutrons in an atom. [Ch 2] Isotope - answer - One of several forms of an element having the same number of protons but different numbers of neutrons. [Ch 2] Radioactive isotope - answer - An unstable is
