Answers
1
Which of the following is NOT a characteristic of living things?
reproduction
uses materials & energy
movement
genetic code
2
A controlled experiment allows the scientist to isolate and test
a conclusion
a single variable
several variables
a mass of information
3
The building up or breaking down of materials through chemical reactions is called
messenger pathways
cell fractionation
homeostasis
metabolism
4
The work of scientists usually begins with
creating experiments
careful observations
drawing conclusions
testing a hypothesis
5
The process by which organisms keep their internal conditions fairly constant is called
homeostasis
photosynthesis
evolution
metabolism
6
The farther a ball drops, the higher it will bounce. What is the DEPENDENT variable?
how high the ball bounces
the height from which the ball is dropped
the ball
there is none
7
Which characteristic of life explains why birds fly south for the winter?
they are made up of cells
they are based on a universal genetic code
they respond to their environment
they maintain internal balance
8
The process by which an organism maintains internal balance is
fasting
homeostasis
homeopathic
equilibrium
9
Cell specialization allows cells to
reproduce
respond to their environment
be less complex
perform different functions
10
Information that is NOT numbers is called
qualitative data
development
quantitative data
description
11
Biology is the study of
plants
the ocean
insects
life
12
Growth is
a change in size
a change in function
a change in shape
a new part
13
A controlled experiment....
1 group for which the scientist controls all variables
there are at least 2 groups 1 of which is not tested
proceeds at a slow pace to observe reactions
is repeated many times to be sure the results are accurate
14
Two cells unite to form a new cell
respond to environment
homeostasis
sexual reproduction
asexual reproduction
15
When enough experimental data supports a hypothesis, the hypothesis becomes a(n)
conclusion
fact
inference
theory
16
Which of these in an inference?
My car's battery is dead
I lost my car key.
If I turn the key and step on the gas then my car will start
My car won't start.
17
What is a hypothesis?
tentative explanation that can be tested
fact based on data that is testable
fact that is falsifiable
an unproven theory
18
You suggest that the presence of water could accelerate the growth of bread mold. This is a(n)
conclusion
hypothesis
experiment
analysis
19
A control group and an experimental group are identical EXCEPT for one factor -
vector variable
dependent variable
independent variable
control variable
20
When applying the process of science, which is tested?
question
hypothesis
observation
result
21
Why is it important to have a control group?
it provides extra experimental subjects
required for development of an "if/then" statement
it is the one the scientist is in control of
without one there is no basis for comparison
22
The amount of light and temperature are examples of
methods of energy production
factors necessary for life
factors that affect reproduction
factors to which living things respond
23
Type of reproduction in which a cell simply splits into 2
sexual
antisexual
asexual
24
Which example is an activity that fish most likely uses to maintain homeostasis?
using camouflage to avoid predators
exchanging gases through its gills to regulate oxygen levels
feeding at night to regulate body temperature
moving to deeper water to regulate metabolic wastes
25
A theory
is a problem to be solved
may be revised or replaced
is the opening statement of an experiment
is always true
26
Which of the following is NOT a characteristic of living things?
ability to move
ability to reproduce
response to the environment
growth and development
27
A signal from the outside that produces a response is a
stimulus
control variable
dependent variable
equity factor
28
A hypothesis is only useful if
it can be proven incorrect
the explanation is already known
it can be proven correct
it can be tested
29
The ability to reproduce results is an important part of any
theory
experiment
hypothesis
law
30
A hypothesis must be
testable
unable to be repeated
proven beyond doubt
stated after the experiment
31
Information gathered from observing a plant grow 3 cm over a 2 week period results in
hypotheses
data
inferences
variables
