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