they are made up of cells
they are based on a universal genetic code
they respond to their environment
they maintain internal balance
5

If I turn the key and step on the gas then my car will start
I lost my car key.
My car won't start.
6
Growth is
a change in size
a change in shape
a change in function
a new part
7
A signal from the outside that produces a response is a
control variable
dependent variable
equity factor
stimulus
8
A hypothesis must be
testable
stated after the experiment
unable to be repeated
proven beyond doubt
9
When enough experimental data supports a hypothesis, the hypothesis becomes a(n)
inference
fact
conclusion
theory
10
Biology is the study of
insects
life
plants
the ocean
11
Type of reproduction in which a cell simply splits into 2
antisexual
asexual
sexual
12
Which characteristic of life is more important to the GROUP than to an INDIVIDUAL?
reproduction
respond to environment
growth and development
evolution
13
Which of the following is NOT a characteristic of living things?
genetic code
uses materials & energy
movement
reproduction
14
The process by which an organism maintains internal balance is
equilibrium
homeopathic
fasting
homeostasis
15
Which example is an activity that fish most likely uses to maintain homeostasis?
exchanging gases through its gills to regulate oxygen levels
using camouflage to avoid predators
moving to deeper water to regulate metabolic wastes
feeding at night to regulate body temperature
16
What is a hypothesis?
tentative explanation that can be tested
fact based on data that is testable
fact that is falsifiable
an unproven theory
17
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
18
The process by which organisms keep their internal conditions fairly constant is called
evolution
metabolism
photosynthesis
homeostasis
19
Information gathered from observing a plant grow 3 cm over a 2 week period results in
inferences
variables
data
hypotheses
20
A controlled experiment allows the scientist to isolate and test
a conclusion
several variables
a mass of information
a single variable
21
Which characterisitc is shared by all prokayotes and eukaryotes?
contains DNA
use of photosynthesis to produce energy
ability to move
contains nucleus and organelles
22
The building up or breaking down of materials through chemical reactions is called
messenger pathways
homeostasis
cell fractionation
metabolism
23
Which of the following is NOT a characteristic of living things?
ability to reproduce
ability to move
response to the environment
growth and development
24
A hypothesis is only useful if
it can be proven incorrect
it can be proven correct
the explanation is already known
it can be tested
25
Cell specialization allows cells to
reproduce
be less complex
respond to their environment
perform different functions
26
Information that is NOT numbers is called
qualitative data
quantitative data
description
development
27
When applying the process of science, which is tested?
result
question
hypothesis
observation
28
A control group and an experimental group are identical EXCEPT for one factor -
control variable
dependent variable
vector variable
independent variable
29
The farther a ball drops, the higher it will bounce. What is the DEPENDENT variable?
how high the ball bounces
there is none
the height from which the ball is dropped
the ball
30
Two cells unite to form a new cell
homeostasis
asexual reproduction
sexual reproduction
respond to environment
31
Why is it important to have a control group?
without one there is no basis for comparison
it provides extra experimental subjects
it is the one the scientist is in control of
required for development of an "if/then" statement
32
The amount of light and temperature are examples of
factors necessary for life
methods of energy production
factors that affect reproduction
factors to which living things respond
33
The work of scientists usually begins with
testing a hypothesis
drawing conclusions
careful observations
creating experiments
