1
The building up or breaking down of materials through chemical reactions is called
homeostasis
messenger pathways
cell fractionation
metabolism
2
The amount of light and temperature are examples of
factors necessary for life
factors that affect reproduction
methods of energy production
factors to which living things respond
3
The process by which organisms keep their internal conditions fairly constant is called
metabolism
evolution
homeostasis
photosynthesis
4
Growth is
a new part
a change in function
a change in size
a change in shape
5
The process by which an organism maintains internal balance is
fasting
homeopathic
equilibrium
homeostasis
6
When applying the process of science, which is tested?
question
result
hypothesis
observation
7
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
moving to deeper water to regulate metabolic wastes
feeding at night to regulate body temperature
8
Information that is NOT numbers is called
qualitative data
quantitative data
development
description
9
The ability to reproduce results is an important part of any
experiment
hypothesis
theory
law
10
Cell specialization allows cells to
reproduce
respond to their environment
be less complex
perform different functions
11
Which of the following is NOT a characteristic of living things?
genetic code
uses materials & energy
reproduction
movement
12
A controlled experiment allows the scientist to isolate and test
a single variable
a mass of information
several variables
a conclusion
13
Which characteristic of life is more important to the GROUP than to an INDIVIDUAL?
evolution
growth and development
reproduction
respond to environment
14
A signal from the outside that produces a response is a
equity factor
stimulus
control variable
dependent variable
15
Which characteristic of life explains why birds fly south for the winter?
they respond to their environment
they are based on a universal genetic code
they maintain internal balance
they are made up of cells
16
The farther a ball drops, the higher it will bounce. What is the DEPENDENT variable?
the ball
how high the ball bounces
there is none
the height from which the ball is dropped
17
Which characterisitc is shared by all prokayotes and eukaryotes?
contains DNA
contains nucleus and organelles
ability to move
use of photosynthesis to produce energy
18
A controlled experiment....
1 group for which the scientist controls all variables
is repeated many times to be sure the results are accurate
there are at least 2 groups 1 of which is not tested
proceeds at a slow pace to observe reactions
19
A control group and an experimental group are identical EXCEPT for one factor -
control variable
vector variable
independent variable
dependent variable
20
Biology is the study of
the ocean
life
insects
plants
21
Biology is the study of
the environment
the living world
the land, water, and air on Earth
animals and plants only
22
Which of these in an inference?
My car won't start.
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
23
Two cells unite to form a new cell
sexual reproduction
homeostasis
asexual reproduction
respond to environment
24
A hypothesis must be
unable to be repeated
testable
proven beyond doubt
stated after the experiment
25
You suggest that the presence of water could accelerate the growth of bread mold. This is a(n)
experiment
conclusion
analysis
hypothesis
26
Type of reproduction in which a cell simply splits into 2
antisexual
asexual
sexual
27
Information gathered from observing a plant grow 3 cm over a 2 week period results in
variables
hypotheses
inferences
data
28
The work of scientists usually begins with
testing a hypothesis
careful observations
creating experiments
drawing conclusions
29
Which of the following is NOT a characteristic of living things?
growth and development
ability to move
response to the environment
ability to reproduce
30
A hypothesis is only useful if
the explanation is already known
it can be proven incorrect
it can be proven correct
it can be tested
31
Why is it important to have a control group?
required for development of an "if/then" statement
without one there is no basis for comparison
it is the one the scientist is in control of
it provides extra experimental subjects
32
What is a hypothesis?
fact that is falsifiable
fact based on data that is testable
an unproven theory
tentative explanation that can be tested
