Biology Chapter 1: The Study of Life – Flashcards

the science that studies living organisms

anything that possesses all the characteristics of life; have an orderly structure, produce offspring, grow, develop, and adjust to changes in the environment

orderly structure shown by living things

the process of change that occurs during an organism's life to produce a more complex organism

increase in the amount of living material and formation of new structures in an organism; a characteristic of all living things

the process of producing offspring

a reaction to a stimulus

group of similar organisms that can breed and produce fertile offspring

a change in an organism's surroundings that causes the organism to react

inherited characteristic that improves an organism's ability to survive and reproduce in a particular environment

regulation of an organism's internal environment to maintain conditions needed for life

organized way of using evidence to learn about the natural world; also, the body of knowledge that scientists have built up after years of using this process

Summarizing statement of observed experimental facts that has been tested many times and is generally accepted as true

well-tested explanation that makes sense of a great variety of scientific observations

a process in which the procedures used during an experiment may be repeated and the results are evaluated by scientists who are in the same field or are conducting similar research

the moral principles and values held by humans

assumption based on prior experience

orderly, direct information gathering about a natural phenomenon

a series of steps followed to solve problems, including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions

a procedure that is carried out under controlled conditions to discover, demonstrate, or test a fact, theory, or general truth

a testable prediction

variable that is not changed in an experiment

the group that does not receive the experimental treatment.

information gathered from observations

in an experiment, the factor that is being measured and that may change in response to manipulations of the independent variable

Factor in an experiment that researchers manipulate so that they can determine its effect

in an experiment, the group that is exposed to the treatment, that is, to one version of the independent variable

A decimal system of measurement whose units are based on certain physical standards and are scaled on multiples of 10

Le Système International d'Unités, or the International System of Units, which is the measurement system that is accepted worldwide
