Question 1

Question

The process by which cells get a small amount of energy without using oxygen is called anaerobic cellular respiration.

True
False
Question 2
The picture shows a leaf found on an autotrophic plant.

The cells in this leaf are making their own energy by the process of

a
photosynthesis, where carbon dioxide and sunlight at Q and R are taken in and then converted into glucose and oxygen at S and T.
b
respiration, where oxygen and sunlight at Q and R are taken in and then converted into carbon dioxide and glucose at S and T.
c
respiration, where carbon dioxide and oxygen at Q and R are taken in and then converted into thermal energy and methane gas at S and T.
d
photosynthesis, where glucose and oxygen at Q and R are taken in and then converted into water vapor and thermal energy at S and T.
Question 3
A farmer is breeding two different types of plants with varying patterns of inheritance. For Plant Type A, the allele for red petals is (R) and the allele for white petals is (r). The farmer crosses a homozygous red plant with a homozygous white plant. For Plant Type B, the alleles for both red (R) and white (W) petal color are dominant. The farmer crosses a homozygous dominant red plant with a homozygous dominant white plant. The results of the farmer's crosses are shown in the Punnett squares.

What are the inheritance patterns for each of the plant types?

a
Plant Type A shows a recessive pattern of inheritance, and Plant Type B shows a complete dominance pattern of inheritance.
b
Plant Type A shows an incomplete dominance pattern of inheritance, and Plant Type B shows a codominance pattern of inheritance.
c
Plant Type A shows a complete dominance pattern of inheritance, and Plant Type B shows a recessive pattern of inheritance.
d
Plant Type A shows a codominance pattern of inheritance, and Plant Type B shows an incomplete dominance pattern of inheritance.
Question 4


This picture is an example of which ecological relationship?

a
producer/primary consumer
b
predator/prey
c
autotroph/heterotroph
d
primary consumer/secondary consumer
Question 5
Directions: The table below shows several organisms and their food sources. Use the table to answer any questions that follow.

Organism Food Source
Wolf Beavers and moose
Moose Trees (leaves)
Beaver Trees (bark)
Earthworm Organic matter
Tree Makes its own food
Which of the following would initially occur if all the trees disappeared?

a
The number of beaver would increase, as they would no longer compete with moose for food resources.
b
The number of earthworms would decline as the total amount of available organic matter would increase.
c
The number of beavers would decline due to the loss of their primary food source.
d
The number of wolves would immediately decline, as trees are their primary shelter.
Question 6
The images below represent four populations in a food chain.

Which sequence best represents the transfer of energy between these organisms?

a
Toads → Predatory insects → Herbivorous insects → Plants
b
Predatory insects → Herbivorous insects → Plants → Toads
c
Plants → Herbivorous insects → Toads → Predatory insects
d
Plants → Herbivorous insects → Predatory insects → Toads
Question 7
Which of the following examples would most likely exhibit primary succession?

a
clear-cutting a forest to use the lumber to make paper
b
new lava flow from the Cumbre Vieja volcano on the Canary Islands
c
field left fallow by a sugar beet farmer
d
forest fire in a national park
Question 8
In highly populated regions, large amounts of runoff, caused by development, can run into nearby streams. This runoff can be warmer than the existing water in the stream. This warm runoff will most likely

a
increase the amount of oxygen available to organisms in the water.
b
decrease the amount of nitrogen for plants in the soil under the water.
c
kill some species of fish as they cannot handle the higher temperature of water.
d
cause the stream to become cleaner by killing bacteria with the heated water.
Question 9
Which of the following best describes how the Greenhouse effect leads to climate change?

What is the greenhouse effect? | Global Ideas on Make a GIF

a
Mining and burning fossil fuels, like coal and natural gas which were buried deep underground, releases carbon dioxide and other greenhouse gases into the air
b
Warmer temperatures lead to more ice melt, which allows more energy from the sun to be absorbed by the ground
c
Excess amounts of greenhouse gases trap more heat in the atmosphere
d
All of the above
Question 10
The drawings below show a young sunflower plant at different times of the day.

Which of the following describes the plant's movement?

a
It bends away from the pull of gravity.
b
It bends away from light.
c
It bends toward light.
d
It bends toward water.
