Autotrophs (plants/algae) might survive when heterotrophs cannot, because autotrophs (plants/algae)are able to
become dormant
exist without respiration
reproduce asexually
make their own food
2

Watson-first to observe cells
Darwin-invented the electron microscope
Linnaeus-devised a binomial system for naming organisms.
Miller-first to observe mitotic cell division
3
An activity carried on by every living plant and animal is...
reproduction
transpiration
respiration
photosynthesis
4
The independent variable of an experiment is
the factor that doesn't matter
the factor that is measured
the factor that the scientist has control over; factor that is being tested
the factor that stays the same
5
Which statement best illustrates the life process of growth?
A bean seed germinates.
A dog consumes a bowl of food.
Two monosaccharides are formed from a disaccharide.
An amoeba moves away from bright light.
6
Which statement concerning organism A and B is correct?
Organism A contains tissues while organism B lacks tissues.
A & B have structures that perform life processes.
Organism A & B have the same organ systems.
Organism A and organism B have the same organs.
7
One characteristic of all living things is that they
maintain internal stability (homeostasis).
synthesize only inorganic matter.
develop organ systems.
produce identical offspring.

State the general relationship between water depth and the number of fish species found
As water depth increases, the # of fish species increases
The deeper the water, the more fish species are found
The deeper the water, the fewer the fish species found
The deeper the water, the # of fish species stays the same

respiration
reproduction
growth
regulation
19
Nutrition is the life function whereby organisms
convert energy from food into a usable form (ATP)
obtain and process materials (food) needed for other activities
remove cellular waste products
exchange gases with their environment
20
This life function involves the circulation & absorption of materials into cells
regulation
respiration
transport
excretion
21
All
living things
produce identical offspring
