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