10
The process by which organisms keep everything inside their bodies within certain limits is
homeostasis

11
How do scientific theories compare to hypotheses?
Theories unify a broad range of observations and hypotheses
Hypotheses are the dominant view among scientists
Theories are the same as hypotheses?
Hypotheses combine ideas of several theories
12
The process by which a cell divides into two daughter cells is called
interphase
metaphase
cell division
mitosis
13
A theory
is a problem to be solved
is the opening statement of an experiment
may be revised or replaced
is always true
14
Hypotheses arise from
knowledge, inferences and imagination
prior knowledge
informed, creative imagination
logical inferences
15
Cells fall into two broad categories, depending on whether they have
genetic material
chloroplasts
a nucleus
a cell wall
16
Which means of particle transport requires input of energy from the cell?
facilitated diffusion
active transport
osmosis
diffusion
17
Unlike
photosynthesis, cellular respiration occurs in
all eukaryotic cells
all but plant cells
animal cells only
plant cells only
18
Information gather from watching a plant grow 3 cm over a 2 week period is
hypothesess
data
inferences
variables
19
Which of the following is NOT a goal of science?
to use scientific explanations to make useful predictions
to investigate and understand the natural world
to explain events in the natural world
to use data to support a particular point of view
20
When the body needs to exercise for longer than 90 seconds it makes ATP by doing
cellular respiration
glycolysis
alcoholic fermentation
lactic acid fermentation
21
The two main stages of cell division are
mitosis and cytokinesis
synthesis and cytokinesis
the M phase and S phase
mitosis and interphase
22
During normal mitosis, a cell with 8 chromosomes will produce 2 daughter cells each with
4 chromosomes
8 chromosomes
2 chromosomes
16 chromosomes
23
The gas given off by a plant during photosynthesis is
water
carbon dioxide
ATP
oxygen
24
A controlled experiment allows the scientist to isolate and test
several variables
a conclusion
a single variable
a mass of information
25
The two main types of fermentation are called
alcoholic and aerobic
aerobic and anaerobic
lactic acid and anaerobic
alcoholic and lactic acid
26
Diffusion occurs because
concentration is always the same throughout a solution
concentration is ever the same throughout a solution
molecules constantly move and collide with each other
molecules never move or collide with each other
27
Organisms such as plants that make their own food are called
thylakoids
pigments
autotrophs
heterotrophs
28
The rate at which wastes are produced depends on a cell's
surface area
volume
ratio of surface area to volume
environment
29
Which of the following is NOT a characteristic of all living things?
ability to reproduce
growth and development
response to the environment
ability to move
30
Which of the following is a function of the cell membrane?
breaks down lipids, carbohydrates and proteins from food
regulates which materials enter and leave the cell
keeps the cell wall in place
stores water, salt, proteins and carbohydrates
31
The cell cycle is the
series of events cells go through as they grow and divide
time it takes for one cell to go through mitosis
period of time between the birth and death of a cell
time from prophase to cytokinesis
32
The thin flexible barrier around a cell is called the
cytoplasm
cell membrane
cell envelope
cell wall
33
Diffusion is the movement of molecules from an area of
equilibrium to low concentration
