1. Even though the weather is cold, the
squirrel maintains a constant body
temperature. What is this trait called?
A.
B.
C.
D.
biogenesis
homeostasis
hypothesis
metamorphosis
constant = homeostasis
2. After the last step of mitosis, the next
thing a cell does is
A.
B.
C.
D.
Mitosis goes from 1 cell to 2 cells
make a copy of its DNA
split into two identical cells
condense its DNA into chromosomes
line up its chromosomes in the middle of
the cell
3. The heart helps circulate blood. The
heart is a type of
a. organ
b. organelle
c. organism
The heart is an organ in what organ system?
d. organ system
CIRCULATORY
4. The pharynx, larynx, and trachea are
all components of which system?
It doesn’t matter if you are not sure about
the pharynx and larynx…
we have studied
the two tubes in the throat:
A. Digestive
the
B. esophagus
Circulatory= digestion,
therefore
the trachea = respiratory!
C. Endocrine
D. Respiratory
5. The alveoli in our lungs help us by
A. carrying oxygen =toblood,
the brain
aka circulatory
B. storing oxygen until
it is needed
= storing
happensbyinthe
cells
body
C. diffusing oxygen from the lungs into the
blood
D. breaking down oxygen into more useful
chemicals = chemical stuff happens in cells
6. Amoebas cannot produce their own
food, whereas diatoms can, because
diatoms contain
A.
B.
C.
D.
chlorophyll
cilia = movement
cytoplasm = jelly in cell
flagella = movement
7. Which of the following does NOT
belong to either the plant or the animal
kingdom?
ANIMALIA
A.
bacteria
PLANTAE
B.
gymnosperms
FUNGI
C.
sponges
PROTISTA
D.
vertebrates
EUBACTERIA
ARCHAEBACTERIA
8. Which of the following is NOT a
defining characteristic of animals?
A.
B.
C.
D.
ability to move
multicellular organisms
radial or bilateral symmetry
ability to produce their own food
9. New cells are formed when existing
cells
A.
B.
C.
D.
die
divide
grow
mutate
mitosis = cell division =
makes new cells = growth
10. Which of the following is true,
according to cell theory?
A.
B.
C.
D.
All cells come from other cells.
Each cell has a central nucleus.
All cells can make their own food.= plant
Each cell has a cell wall. = plant
11. A tree’s bark is most similar in
function to a
A.
B.
C.
D.
bull’s horns
clam’s shell
cat’s whiskers
zebra’s stripes
Tree bark = clam shell = cell wall
12. Some plant cells contain chloroplasts, but
animal cells do not. Which statement best
explains why animal cells are able to function
without chloroplasts?
A. Animal cells do not need outside energy.
B. Animals obtain energy by consuming other organisms.
C. Photosynthesis occurs in other organelles
in animal cells.
D. Animal cells have circulatory systems,
but plant cells do not.
13. Which of
these word
equations
represents the
process of
respiration?
= opposite of
photosynthesis
A. H2O + oxygen →
sugar + CO2
B. CO2 + oxygen →
sugar + H2O
C. CO2 + H2O →
sugar + oxygen
D. sugar + oxygen →
CO2 + H2O
14. Which of the following is a biotic
factor in an aquatic ecosystem?
Biotic = living
A.
B.
C.
D.
freshwater
dissolved nitrates
dissolved oxygen
photosynthetic algae
15. Which of the following is an abiotic
factor in a forest ecosystem?
Abiotic = not living
A.
B.
C.
D.
deer
fungus
moss
sunlight
16. Which type of organism is a
heterotroph?
heterotroph=
cannot make
A.
its own food
B.
C.
D.
Then find similarity
in the answers!
oak trees = plant
slime mold
green algae = plants are green
photosynthetic =bacteria
plants
do that!
17. Chromosomes are cell structures that
A.
B.
C.
D.
release energy
protect the cell
Store genetic information
kill microorganisms
chromosome = DNA = genes or
genetics = heredity
18. Which process results in a decrease in
the number of chromosomes?
A. mitosis
Hmmm… what
B. meiosis
can we mark
C. Fertilization
fertilization = joins egg
& sperm
out?
D. asexual reproduction
mitosis = asexual reproduction
19. Which of the following are
formed by meiosis?
A.
B.
C.
D.
egg cells only
sperm cells only
both egg and sperm cells
neither egg nor sperm cells
meiosis = reproductive cells
= egg & sperm
20. The process of an organism passing
on traits to its offspring is called
A.
B.
C.
D.
heredity
a pedigree
phenotyping
a Punnett square
traits = heredity
