Bio 100 First Exam UPDATED Exam
Questions and CORRECT Answers
Biology - CORRECT ANSWER - the scientific study of life
Seven properties associated with life - CORRECT ANSWER - Order, regulation, growth
& development, energy processing, response to the environment , reproduction, evolution.
The smallest level of biological organization that can display all the characteristics of life -
CORRECT ANSWER - a cell
Biosphere - CORRECT ANSWER - Consists of all the environments on Earth that support
life-including soil; oceans, lakes, and other bodies of water and the lower atmosphere.
Ecosystem - CORRECT ANSWER - All the living factors with which they interact.
Prokaryotic cell - CORRECT ANSWER - A type of cell lacking a nucleus and other
organelles. Only found in the domains Bacteria and Archaea
Eukaryotic cell - CORRECT ANSWER - A type of cell that has a membrane-enclosed
nucleus and other membrane-enclosed organelles. All organisms minus Bacteria and Archaea
Gene - CORRECT ANSWER - A unit of inheritance in DNA consisting of a specific
nucleotide sequence that programs the amino acid sequence that programs the amino acid
sequence of a polypeptide. Most of the genes of a eukaryote are located in its chromosomal
DNA; a few are carried by the DNA of mitochondria and chloroplasts.
Three domains of life - CORRECT ANSWER - Bacteria, Archaea, and Eukarya.
, Natural selection - CORRECT ANSWER - A process in which organisms with certain
inherited characteristics are more likely to survive and reproduce than are organisms with other
characteristics; unequal reproductive success.
Science - CORRECT ANSWER - a way of knowing, an approach to understanding the
natural world that is based on inquiry-a search for information, explanations, and answers to
specific questions.
Discovery science - CORRECT ANSWER - The process of scientific inquiry that focuses
on using observations to describe nature
Scientific method - CORRECT ANSWER - Scientific investigation involving the
observation of phenomena, the formulation of a hypothesis concerning the phenomena,
experimentation to demonstrate the truth or falseness of the hypothesis, and the results that
validate or modify the hypothesis.
Hypothesis-driven science - CORRECT ANSWER - The process of scientific inquiry that
uses the steps of the scientific method to answer questions about nature.
Controlled experiment - CORRECT ANSWER - A component of the process of science
whereby a scientist carries out two parallel tests, an experiment test and a control test. The
experimental test differs from the control by one factor, the variable.
Theory - CORRECT ANSWER - A widely accepted explanatory idea that is broad in
scope and supported by a large body of evidence
Ecology - CORRECT ANSWER - the scientific study of the interactions between
organisms and their environments, offers a different perspective on life.
Abiotic factor - CORRECT ANSWER - A nonliving component of an ecosystem, such as
air, water, light, minerals, or temperature.
