1
The process by which organisms keep their internal conditions fairly constant is called
photosynthesis
metabolism
homeostasis
evolution
2
Which example is an activity that fish most likely uses to maintain homeostasis?
feeding at night to regulate body temperature
exchanging gases through its gills to regulate oxygen levels
using camouflage to avoid predators
moving to deeper water to regulate metabolic wastes
3
Information gathered from observing a plant grow 3 cm over a 2 week period results in
inferences
data
variables
hypotheses
4
The building up or breaking down of materials through chemical reactions is called
messenger pathways
metabolism
homeostasis
cell fractionation
5
Two cells unite to form a new cell
homeostasis
sexual reproduction
asexual reproduction
respond to environment
6
A control group and an experimental group are identical EXCEPT for one factor -
vector variable
control variable
independent variable
dependent variable
7
Which of the following is NOT a characteristic of living things?
genetic code
movement
uses materials & energy
reproduction
8
The metric system is easy to use because
it is scaled on fractions
allows scientists to be safe
not used in the United States
Based on units of 10
9
A hypothesis must be
stated after the experiment
unable to be repeated
testable
proven beyond doubt
10
A controlled experiment....
1 group for which the scientist controls all variables
proceeds at a slow pace to observe reactions
is repeated many times to be sure the results are accurate
there are at least 2 groups, 1 of which is not altered
11
Biology is the study of
the ocean
life
plants
insects
12
Type of reproduction in which a cell simply splits into 2
sexual
antisexual
asexual
13
When applying the process of science, which is tested?
result
hypothesis
observation
question
14
A signal from the outside that produces a response is a
equity factor
stimulus
dependent variable
control variable
15
A personal point of view which is not scientific is known as a
conclusion
bias
model
hypothesis
16
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
17
Which of the following is NOT a characteristic of living things?
growth and development
response to the environment
ability to move
ability to reproduce
18
1000 milliliters equals 1
meter
liter
centiliter
microliter
19
The ability to reproduce results is an important part of any
law
hypothesis
theory
experiment
20
Which of these in an inference?
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
My car won't start.
21
The process by which an organism maintains internal balance is
homeopathic
fasting
equilibrium
homeostasis
22
Which characterisitc is shared by all prokayotes and eukaryotes?
contains DNA
contains nucleus and organelles
use of photosynthesis to produce energy
ability to move
23
The farther a ball drops, the higher it will bounce. What is the DEPENDENT variable?
the height from which the ball is dropped
the ball
there is none
how high the ball bounces
24
A theory is
a hypothesis
an observation that defines a problem
just a guess
a tested highly reliable explanation of events in the natural world
25
Cell specialization allows cells to
be less complex
perform different functions
respond to their environment
reproduce
26
You suggest that the presence of water could accelerate the growth of bread mold. This is a(n)
conclusion
analysis
hypothesis
experiment
27
Why is it important to have a control group?
it provides extra experimental subjects
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
28
Growth is
a change in size
a change in shape
a new part
a change in function
29
Biology is the study of
the living world
the environment
animals and plants only
the land, water, and air on Earth
30
The amount of light and temperature are examples of
factors to which living things respond
methods of energy production
factors that affect reproduction
factors necessary for life
31
What is a hypothesis?
fact that is falsifiable
fact based on data that is testable
an unproven theory
tentative explanation that can be tested
32
A controlled experiment allows the scientist to isolate and test
a mass of information
a single variable
several variables
a conclusion
33
Information that is NOT numbers is called
development
description
qualitative data
quantitative data
34
The best way for a scientist to communicate results of their work is
write an editorial for a newspaper
hold a press conference
write an article for a national magazine like "Time"
publish in a peer review journal
35
A hypothesis is only useful if
it can be proven incorrect
it can be tested
the explanation is already known
it can be proven correct
