UPDATED ACTUAL Exam Questions and
CORRECT Answers
Biology - CORRECT ANSWER - the scientific study of life
Levels of Organization - CORRECT ANSWER - atoms, molecules and macromolecules,
cells, tissues, organs, organisms, population, community, ecosystem, biosphere
Key Features of Life - CORRECT ANSWER - cells and organization, energy and
metabolism, response to environmental changes, regulation and homeostasis, grown and
developments, reproduction, biological evolution
All Cells - CORRECT ANSWER - enclosed by a membrane and use DNA
Eukaryotic Cell - CORRECT ANSWER - has membrane-enclosed organelles
- plants, animals, fungi
Prokaryotic Cell - CORRECT ANSWER - simpler and smaller, does not contain a nucleus or
other membrane-enclosed organelles
Negative Feedback - CORRECT ANSWER - as more product accumulates, the process that
creates it slows and less of the product is created
Positive Feedback - CORRECT ANSWER - as more of a product accumulates, the process
that creates it speeds up and more of the product is produced
Two Main Types of Scientific Inquiry - CORRECT ANSWER - discovery science,
hypothesis-based science
,Discovery Science - CORRECT ANSWER - describes natural structures and processes, based
on observation and the analysis of data
Hypothesis - CORRECT ANSWER - a tentative answer to a well-framed question
A Theory Is - CORRECT ANSWER - broader in scope than a hypothesis, general and can
lead to new testable hypotheses, supported by a large body of evidence in comparison to a
hypothesis
Matter - CORRECT ANSWER - consists of chemical elements in pure form and in
combinations called compounds
- anything that takes up space and has mass
Element - CORRECT ANSWER - substance that cannot be brown down to there substances
by chemical reactions
Compound - CORRECT ANSWER - substance consisting of two or more elements in a fixed
ratio
- has characteristics different from those of its elements
Essential Elements - CORRECT ANSWER - carbon, hydrogen, oxygen, and nitrogen
- 95% of matter
calcium, phosphorus, potassium, and sulfur
-4%
remaining amount are trace elements
Atom - CORRECT ANSWER - the smallest unit of matter that still retains the properties of
an element
- each element consists of unique atoms
, Neutron - CORRECT ANSWER - no electric charge
Proton - CORRECT ANSWER - positively charged particle
- determines the elements atomic number
Electron - CORRECT ANSWER - negatively charged particle
Mass Number - CORRECT ANSWER - sum of the protons plus neutrons in the nucleus
Isotopes - CORRECT ANSWER - two atoms of an element that differ in number of neutrons
- applications: dating fossils, tracing atoms through metabolic processes, diagnosing medical
disorders

Covalent Bond - CORRECT ANSWER - the sharing of a pair of valence electrons by two
atoms in a covalent bond, the sacred electrons count as part of each atom's valence shell
- atoms are stable when their outermost shell is full
- can form between atoms of the same or different elements
Valence - CORRECT ANSWER - bonding capacity
- the number of unpaired shared electors required to complete the valence shell
