Biology 1111 FINAL EXAM REVIEW
AND 100% ACTUAL ANSWERS 2025
UPDATE.
Because scientists are in the business of investigating nature, scientists function as: - Answer
society's eyes and ears on the natural world.
Which of the following is true? - Answer A scientific theory explains what we know to this date
about a natural event.
Choose the answer that best describes the sequence of the scientific method. - Answer
observation, hypothesis, experiment, conclusion
A scientific explanation that is tentative and testable is termed a/an" - Answer hypothesis
Which of the following is a theory? - Answer There is molecular and biochemical evidence that
all organisms are related.
The difference between a theory and a hypothesis is that a: - Answer theory must be
supported by evidence.
Which scientist disproved the theory of spontaneous generation? - Answer Pasteur
If you flip the light switch in your living room and nothing happens, what might be a hypothesis
to explain the absence of light? - Answer The circuit breaker for the living room might be in
the "off" position.
Which one of the following is true about scientific knowledge? - Answer Scientific knowledge
is not absolute, because the possibility is always held open that new experiments may one day
prove it wrong.
When Pasteur tested the hypothesis of spontaneous generation, he compared the ability of a
sterilized growth medium (meat broth) to produce a population of bacteria in two different
types of flasks. One had a simple neck open to the outside, and the other had a "goose neck"
bend that also was open to the environment. In this experiment, the standard neck flask served
,Living things inherit information from their parents encoded in: - Answer DNA
The liver releases glucose into the bloodstream if you don't eat for a long time. This represents
an example of a characteristic possessed by all living things. Which is it? - Answer maintaining
a relatively constant internal environment
Which of the following is the correct order or complexity, going from least to most complex? -
Answer atom, molecule, organelle, cell, tissue, organ
Which of the following is an example of how living things assimilate energy? - Answer eating a
meal
Biology developed as a science later than physics because: - Answer the living world is
tremendously diverse compared to the non-living world.
Evolution allows us to explain: - Answer both the diversity of life and how all living things are
related.
A measure of the quantity of matter in an object is know as: - Answer mass.
If a neutral atom has an atomic number of 10, then we know that is has: - Answer 10 protons
and 10 electrons.
An atom whose atomic number is 10 has how many electrons in its outermost energy level? -
Answer eight
Isotopes are atoms of the same element that differ in their: - Answer number of neutrons.
Which of the following are found in the nucleus of an atom? - Answer protons and neutrons
An element with 22 protons, 22 neutrons, and 22 electrons would have an atomic number of: -
Answer 22.
, You have a substance and begin a set of experiments in which you break it down into other
substances through chemical reactions. After a few successive reactions, you discover a set of
products that can't be broken down further, no matter what type of chemical reaction you
attempt. Theses substances are: - Answer elements.
Atoms with eight electrons in their outer shells tend to: - Answer be stable and unreactive.
Which of the following results from the making of a bond? - Answer Atoms become more
stable.
An atom will react with other atoms only until: - Answer it has completely filled its outermost
energy level.
The number of atoms coming out of a chemical reaction must equal the number of atoms going
into a chemical reaction. This follows the principle of: - Answer the law of conservation of
mass.
The naturally occurring helium atom is chemically inert because: - Answer its outermost shell
is filled with electrons.
Which of the following is true of chemical bonds? - Answer Electrons can be shared or
completely transferred.
Atoms form bonds to: - Answer fill their outer shells with electrons.
Two hydrogen atoms (atomic number 1) form a covalent bond. Which of the following is true? -
Answer Both hydrogen atoms now have two electrons in their outer shell.
Oxygen has six electrons in its second outer shell, and hydrogen has one. With how many
hydrogen atoms will oxygen form covalent bonds? - Answer two
Water is a polar molecule because: - Answer oxygen is more electronegative than hydrogen.
What is the difference between an ionic and covalent bond? - Answer In an ionic bond, one
atom accepts electrons from the other; in a covalent bond, a pair of atoms share electrons.
