The larva's form resembles that of the adult.
B.
There are three distinct stages.
C.
During its life cycle, the insect changes its appearance dramatically.

after a plant sperm cell fertilizes
an egg cell?

sweet nectar
C.
a spore
D.
plant nutrients
Which terms are used for cells
that are required for plants to
reproduce sexually?
A.

B.
offspring and clones
C.
antigens and antibodies
D.
eggs and sperm
Which activity distinguishes the
larva stage from the pupa stage
of an insect?
A.
locating shelter
B.
making its own food
C.
reproducing
D.
feeding
In plants, tubes transport nutrients throughout the
plant.
In humans, which parts carry out that function?
A.
blood vessels
B.
small intestines
C.
nerves
D.
alveoli
Which describes a disadvantage of
sexual reproduction?
A.
inherits traits for better survival
B.
is genetically identical to parent
C.
takes longer for new individual to develop
D.
has variation in genetic backgrounds
Which statement best describes the
process of asexual reproduction?
A.
A female bird lays an egg after it is fertilized internally
by a male, but it develops externally.
B.
A seed is produced by a sunflower plant.
C.
After fertilizing an egg, a larva transforms into a
butterfly.
D.
A bacterium splits into two separate organisms.
What happens when the body
cannot differentiate between
pathogens and body cells?
The excretory system will remove the
pathogens.
B. The immune system will target the body’s own
cells.
C. The organism will develop allergies.
D. The digestive system will absorb the
pathogens.
A.
Which part of a sperm cell is
responsible for providing the
cell's energy?
A. flagellum
B.
cell wall
C. mitochondria
D. round
head
section
In a plant, roots absorb water and nutrients. Those materials are then
transported to other parts of the plant.
Which statements describe the system in an animal that functions in a
similar way?
Choose all answers that are correct.
A.
The responsibilities of transporting materials throughout the
animal's body are done by the circulatory system.
B.
An animal's blood moves nutrients throughout the animal's
body like water in a plant's system moves nutrients.
C.
The endocrine system transports materials throughout the
animal's body.
D.
Nutrients are moved in a plant by water, like the hormones
that move nutrients throughout an animal's body.
Which best explains what would
happen to the muscular system if
the digestive system broke down?
A.
No energy would be available to the cells, and the
organism would not be able to move.
B.
Oxygen would not be removed, and the muscles
would not be able to move.
C.
No carbon dioxide would be available to the cells,
and the organism would die.
D.
An increase in wastes would be sent to each cell, and
they would become infected.
Which best describes the life
cycle of an insect that undergoes
complete metamorphosis?
A.
larva → egg → pupa → adult; adult still produces an exoskeleton regularly
B.
egg → larva → pupa → adult; adult still produces a cocoon
C.
egg → larva → pupa → adult; adult is fully formed and capable of reproduction
D.
egg → pupa → larva → adult; adult is fully formed, but is not capable of reproduction
Which statement describes the life
cycle of a grasshopper?
A.
incomplete metamorphosis
B.
stages of adolescence before adulthood
C.
complete metamorphosis
D.
begins with a seed or spore
Why do two giraffes have spots with
different shapes and patterns?
A.
exposure to sunlight
B.
different inherited traits are expressed
C.
different acquired traits
D.
color change based on diet
Through which are wastes,
nutrients, and gases primarily
transported in a plant?
A.
within the seeds and roots
B.
within seeds and spores
C.
within the stem and roots
D.
within spores and flowers
How does the immune system
work together with the circulatory
system to function properly?
A.
White blood cells move through the body (to parts where they
are needed) in the blood vessels of the circulatory system to
destroy pathogens.
B.
The circulatory system's arteries cause the immune system to work
harder by bringing oxygen-depleted blood to the infection site.
C.
Red blood cells released by immune cells cause increased blood
flow to the infection site; this increased blood flow brings other
red blood cells to the area more quickly.
D.
The immune system's red blood cells fight and destroy foreign
antigens.
