1
Which statement best describes cellular respiration?
It uses carbon dioxide and produces oxygen
It occurs in animal cells but not in plant cells
It converts energy in food into a more usable form (ATP)
It stores energy in food molecules
2
One characteristic of all living things is that they
maintain internal stability (homeostasis).
synthesize only inorganic matter.
produce identical offspring.
develop organ systems.
3
The scientific name for humans, Homo sapiens, indicates the
phylum and genus
genus and species
kingdom and species
kingdom and phylum
4
Which scientist is correctly paired with his contribution to biology?
Linnaeus-devised a binomial system for naming organisms
Miller-first to observe mitosis
Watson-first to observe cells
Darwin-invented the electron microscope
5
Which scientist is correctly paired with his contribution to biolocial science?
Watson-first to observe cells
Miller-first to observe mitotic cell division
Darwin-invented the electron microscope
Linnaeus-devised a binomial system for naming organisms.
6
This life function results in the production of new individuals (ex: asexual or sexual)
reproduction
respiration
regulation
growth
7
Which statement best illustrates the life process of growth?
A bean seed germinates.
Two monosaccharides are formed from a disaccharide.
An amoeba moves away from bright light.
A dog consumes a bowl of food.
8
State the general relationship between water depth and the number of fish species found
The deeper the water, the fewer the fish species found
The deeper the water, the # of fish species stays the same
The deeper the water, the more fish species are found
As water depth increases, the # of fish species increases
9
The life process a plant performs to make a variety of substances such as poisons & drugs is..?
excretion
synthesis
digestion
respiration
10
An increase in the size of cells, the number of cells, & the overall size of the organism is...
metabolism
cyclosis
nutrition
growth
11
In this life process
simple
materials
combine chemically
to form more
complex
materials
...
reproduction
synthesis
respiration
cyclosis
12
This life function involves the circulation & absorption of materials into cells
regulation
respiration
transport
excretion
13
Every single-celled organism is able to survive because it carries out
metabolic activities
autotrophic nutrition
sexual reproduction
heterotrophic nutrition
14
Autotrophs (plants/algae) might survive when heterotrophs cannot, because autotrophs (plants/algae)are able to
reproduce asexually
become dormant
exist without respiration
make their own food
15
Nutrition is the life function whereby organisms
remove cellular waste products
convert energy from food into a usable form (ATP)
obtain and process materials (food) needed for other activities
exchange gases with their environment
16
The independent variable of an experiment is
the factor that the scientist has control over; factor that is being tested
the factor that stays the same
the factor that is measured
the factor that doesn't matter
17
Which statement best describes cellular respiration?
It occurs in animal cells but not in plant cells.
It stores energy in food molecules.
It uses carbon dioxide and produces oxygen.
It converts energy in food into a more usable form.
18
An organism's scientific name indicates the
phylum and species
kingdom and species
kingdom and phylum
genus and species
19
Eliminating metabolic wastes is characteristic of this life process
ingestion
transport
excretion
secretion
20
Which term includes all the activities required to keep an organism alive?
metabolism
growth
respiration
excretion
21
Which statement concerning organism A and B is correct?
Organism A & B have the same organ systems.
Organism A contains tissues while organism B lacks tissues.
A & B have structures that perform life processes.
Organism A and organism B have the same organs.
22
A mushroom belongs to which kingdom ?
Animal
Fungi
Protist
Plant
23
An activity carried on by every living plant and animal is...
transpiration
photosynthesis
reproduction
respiration
24
All
living things
develop organ systems
have the ability to maintain a steady state (homeostasis)
have the ability to synthesize only inorganic matter
produce identical offspring
