Answers
1
A signal from the outside that produces a response is a
stimulus
equity factor
dependent variable
control variable
2
The building up or breaking down of materials through chemical reactions is called
messenger pathways
homeostasis
cell fractionation
metabolism
3
Biology is the study of
life
plants
the ocean
insects
4
Which of the following is NOT a characteristic of living things?
uses materials & energy
movement
genetic code
reproduction
5
The process by which organisms keep their internal conditions fairly constant is called
homeostasis
evolution
metabolism
photosynthesis
6
The work of scientists usually begins with
drawing conclusions
careful observations
creating experiments
testing a hypothesis
7
Type of reproduction in which a cell simply splits into 2
asexual
antisexual
sexual
8
Regulating body temperature is an example of what characteristic of living organisms?
reproduction
homeostasis
response to stimulus
cell theory
9
A hypothesis must be
proven beyond doubt
testable
unable to be repeated
stated after the experiment
10
Growth is
a change in shape
a change in function
a change in size
a new part
11
What is a hypothesis?
tentative explanation that can be tested
an unproven theory
fact that is falsifiable
fact based on data that is testable
12
Two cells unite to form a new cell
asexual reproduction
homeostasis
respond to environment
sexual reproduction
13
Which characteristic of life is more important to the GROUP than to an INDIVIDUAL?
reproduction
respond to environment
evolution
growth and development
14
A controlled experiment....
there are at least 2 groups 1 of which is not tested
1 group for which the scientist controls all variables
is repeated many times to be sure the results are accurate
proceeds at a slow pace to observe reactions
15
Which characteristic is shared by all cells?
contains DNA
ability to move
use of photosynthesis to produce energy
live in colonies of more cells
16
Cell specialization allows cells to
be less complex
perform different functions
respond to their environment
reproduce
17
The amount of light and temperature are examples of
factors to which living things respond
factors that affect reproduction
factors necessary for life
methods of energy production
18
Why is it important to have a control group?
it provides extra experimental subjects
it is the one the scientist is in control of
without one there is no basis for comparison
required for development of an "if/then" statement
19
Cell specialization (differentiation) in an organism allows cells to
perform different functions.
respond to their environment.
be less complex.
reproduce
20
Which of the following is NOT a way that science influences society?
Advances useful technology to society.
Help society’s undersand how people affect the environment.
Provides answers to society’s practical problems.
Gives society answers to difficult ethical issues.
21
The ability to reproduce results is an important part of any
hypothesis
law
experiment
theory
22
You suggest that the presence of water could accelerate the growth of bread mold. This is a(n)
analysis
hypothesis
conclusion
experiment
23
Which of the following is NOT a characteristic of living things?
ability to reproduce
response to the environment
growth and development
ability to move
24
Information gathered from observing a plant grow 3 cm over a 2 week period results in
inferences
data
variables
hypotheses
25
Which characteristic of life explains why birds fly south for the winter?
they respond to their environment
they are made up of cells
they are based on a universal genetic code
they maintain internal balance
26
Viruses contain which of the following characterstics of life?
Have metabolism
Made of cells
Maintain homeostasis
Evolve
27
The picture illustrates which characteristic of living things?
Are made up of cells.
Need material and energy.
Grow and develop
Reproduce.
