Biology ACTUAL Exam
#1 LATEST 2026-2027
WITH QUESTIONS AND
CORRECT VERIFIED ANSWERS
GRADED A+
prediction-ANSWERS-a guess of what might happen based on observation-- the
outcome you would observe if your hypothesis was supported
theory-ANSWERS-a sound explanation of the world supported through continued
observation and experiments over a long period of time
3 components of a controlled experiment-ANSWERS-1. variable
2. test group
3. control group
variable-ANSWERS-feature of an experiment that is changed from one treatment to
the next
test group-ANSWERS-exposed to variable in an experiment
control group-ANSWERS-not exposed to the variable in an experiment
, importance of test group & control group-ANSWERS-they allow researchers to
determine whether the variable in an experiment has an effect
independent variable-ANSWERS-manipulation performed on the test group
(ex. hours of tutoring)
which axis is the independent variable found on a graph?-ANSWERS-x-axis
dependent variable-ANSWERS-effect that is being measured
(ex. test score)
which axis is the dependent variable found on a graph?-ANSWERS-y-axis
theory of evolution-ANSWERS-set of hypotheses that provide a powerful explanation
for both biological observations & the diversity of life
why do we learn that the theory of evolution is the single most important theory in all of
biology?-ANSWERS-there's lots of evidence from asking/testing good scientific
questions
(ex. anatomy, fossil record, biogeography, molecular biology)
7 ways living organisms are different from non-living organisms-ANSWERS-1.
organization - complex organization
2. response - ability to change in response to the environment
3. reproduction - ability to reproduce
4. evolution - capacity to evolve
5. metabolism - chemical rxns that sustain life
6. homeostasis - maintenance of stable internal environment
7. growth - regulated growth/cell division
1st law of thermodynamics-ANSWERS-energy can neither be created nor destroyed; it
can only be transformed from one form into another
how does the 1st law of thermodynamics apply to living organisms?-ANSWERS-- living
organisms transform energy from sunlight --> chemical energy
- cells convert energy by expending it & giving off heat as a by product
2nd law of thermodynamics-ANSWERS-the amount of entropy in the universe is
constantly increasing
entropy-ANSWERS-amount of disorder in a system
disorder-ANSWERS-# of states that a system can take on
