Tina observed a cell under a microscope. She concluded that it was a plant cell instead of an animal cell. Which structure helped her come to this conclusion?
a) She saw a vacuole, which animal cells lack.
b) She saw a nucleus, which animal cells lack.
c) She saw a chloroplast, which animal cells lack.
d) She saw a cell membrane, which animal cells lack.

Which two organisms contain chloroplasts and eyespots?
a) amoeba and paramecium
b) paramecium and volvox
c) volvox and euglena
d) euglena and amoeba

How do a paramecium and an amoeba obtain food to live?
a) A paramecium and an amoeba both use contractile vacuoles to capture food.
b) A paramecium and an amoeba both make their own food through photosynthesis.
c) A paramecium collects food in an oral groove, while an amoeba uses pseudopods to surround food.
d) A paramecium uses pseudopods to capture food, while an amoeba uses chloroplasts to make its food.

Barometric pressure has been dropping all day. What weather conditions will most likely occur?
a) sunny weather
b) stormy weather
c) calm weather
d) hot weather

A sea breeze blows from the ocean toward the shore. Why does this occur?
a) High pressure over the land causes a downdraft to occur.
b) The tide carries the wind to the shore as it moves back and forth.
c) Conduction of heat from the warm water produces wind from the ocean.
d) Air over land heats faster than air over water, which causes convection.

Which explains why most of the rain that falls comes from the ocean?
a) The majority of evaporation takes place over the ocean.
b) The majority of precipitation takes place over the ocean.
c) Most rivers deposit freshwater into the ocean.
d) Most clouds form near or over the ocean.

Why does the troposphere experience the greatest amount of atmospheric pressure compared to the other atmospheric layers?
a) It produces the ozone layer
b) It has the highest temperatures
c) It contains a high concentration of gas particles
d) It is the region in which weather occurs

How do forces act on a dropped object as it is falling?
a) Air resistance is pushing up on the object, while gravity is pulling it down.
b) Air resistance is pulling down on the object, while gravity is pushing it up.
c) Both gravity and air resistance are pulling down on the object.
d) Both gravity and air resistance are pushing up on the object.

How can simple machines make work easier?
a) By decreasing the force needed to complete the task
b) By increasing the friction between the machine and the object
c) By adding more work on the object than originally applied.
d) By removing the force of gravity on the object.

How does the energy of a roller-coaster cart change as it travels from the top of the roller coaster the the bottom?
a) The cart has greater kinetic energy at the top than it does at the bottom.
b) The cart has no energy energy at the top and more energy at the bottom.
c) The cart has less potential energy at the top than it does at the bottom.
d) The cart has potential energy at the top that is transformed to kinetic energy as it moves to the bottom.

Which is a function of the respiratory system?
a) to provide the body with carbon dioxide, which reacts with food to produce energy
b) to provide the body with oxygen, which reacts with food to produce energy
c) to provide the cells with glucose, which is used as a source of energy
d) to provide the cells with water, which is used as a source of energy

Why would the offspring resulting from fertilization have more differences than the offspring resulting from budding?
a) Two parents provide all of their genes to their offspring during budding, unlike during fertilization.
b) Each parent provides half of its genes to its offspring during budding, unlike during fertilization
c) Two parents provide all of their genes to their offspring during fertilization, unlike during budding
d) Each parent provides half of its genes to its offspring during fertilization, unlike during budding.

Two black guinea pigs were crossed and they produced a litter of 4 black and 3 white guinea pigs. Which best explains this occurrence?
a) White fur is dominant to black fur
b) White fur was the result of a mutation
c) Both parents were heterozygous for black fur
d) Both parents were homozygous for black fur

b) Groups of organs form cells, which work together to make up a single tissue.
c) Groups of tissues work together to make up a single organ.
d) Groups of organs work together to make up a single tissue.

How does the cell wall of a plant compare to the plasma membrane of an animal cell?
a) The cell wall controls what enters and leaves the plant cell; the plasma membrane provides mostly structure + support
b) The cell wall converts sunlight into sugars; the plasma membrane controls energy production in the cell.
c) The cell wall provides structure + support; the plasma membrane controls the substances that enter and leave the cell.
d) The cell wall provides structure + support; the plasma membrane is surrounded by a structure that contains genetic informatio

How do forces act on a dropped object as it is falling?
a) Air resistance is pushing up on the object while gravity is pulling it down.
b) Air resistance is pulling down the object while gravity is pushing it up.
c) Both gravity and air resistance are pulling down on the object.
d) Both gravity and air resistance are pushing up on the object.
