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