a.) The cost of batteries and cars would need to be cut.
b.) The batteries would need to powered by gasoline.
c.) More charging stations would have to be built.
d.) Emissions released by electric cars would have to be increased.

a.) obtain energy by eating living plants
b.) release energy to be reused
c.) recycle nutrients from dead plant or animal matter
d.) transform light energy into chemical energy
C.) recycle nutrients from dead plant or animal matter

Why is the gravitational force greater between the objects in row B than row A?
The object on the left in row a has a greater mass giving it a greater gravitational pull.

A male dog and a female dog each weigh 10 pounds. The two dogs have a litter of puppies. Which statement best predicts how much these puppies will weigh when they are full grown?
a.) Each full-grown dog will also weigh exactly 10 pounds because weight is determined by genes.
b.) Each full-grown dog will weigh about 10 pounds weight is influenced by genes and also by diet.
c.) Each full-grown dog will weigh from 5 pounds to 100 pounds because weight is determined entirely by diet.
d.) Each full-grown dog will weigh about 5 pounds, because they inherit half of their genetic material from each parent.
B - Genes and environment will both have an impact on the dog's weight and body composition.

Which can be used as evidence to support a scientist's claim that deforestation is a main contributor to global temperature increases?
a.) Photosynthesis produces oxygen as a waste product.
b.) Plants take in carbon dioxide for use in photosynthesis.
c.) Photosynthesis produces energy, which gives off heat.
d.) Plants produce energy during cellular respiration.
b.) Plants take in carbon dioxide for use in photosynthesis.

Explain why ALL celestial objects in our solar system don't orbit the sun.
Gravitational attraction depends on distance an mass. Some objects may be too small or too far away to be affected by gravity.

Which of the below questions is LEAST important to keep in mind when asking strong scientific questions that help clarify data?
a.) Can the question be answered, and is it relevant to the topic?
b.) Does the question require more than a simple "yes" or "no" response?
c.) How does the question relate to my personal likes and dislikes?
d.) Is the question supported by current data?
C.) Keep your personal beliefs out of it!!

What happens to glucose stored in a plant if the plant were eaten by a deer?
Select TWO answers:
a.) It is broken down in the deer's body and used for energy.
b.) It is combined with other substances and used to repair cells for growth.
c.) It is unavailable to the deer and cycles out of its body.
d.) It is turned into oxygen and muscle.

Evaluate if this model is a good representation of the role that gravity plays in the formation of the Sun and planets.
The model does not represent the gravitational pull towards the center of the dough. There is no object with a large mass in the center to hold in the dough.

Use the table in your packet about Jupiter and its 4 Galilean moons to answer the following question.
A, the table shows the value of the moon's surface gravities.

A student uses a water bottle filled with hot water to warm-up their feet. Explain the how energy is transferred in this situation.
Energy is transferred from the water bottle to the feet causing an increase in kinetic energy of molecules in the feet.

Natural pollinators , particularly bees, have experienced rapid die-offs in recent years. The decline in pollinators is a threat to many native plants.
Which solution would best address this problem?
a.) Identify the causes of the die-off and fix those.
b.) Introduce a new bee to replace lost pollinators.
c.) Plant different crops.
d.) Treat the crops with insecticide.
A.) Identify the cause of the die-off and fix those.

Describe the stages of the solar system formation that are best represented by this model.
The solar system started as a condensed cloud of dust then flattened and expanded into a disk shape. This is similar to the dough as it gets wider and flatter as it spins.

Use the table in your packet about Jupiter and its 4 Galilean moons to answer the following question.
A, Callisto is the furthest of the 4 moons and it has the lowest gravity making it the easiest moon for a probe to be able to leave to return to Earth.

Describe the relationship between the Earth's tilt and the cyclic pattern of the seasons.
The seasons are caused by the tilt of the Earth's axis. For example, in the northern hemisphere when the axis is tilted towards the sun, the NH receives more direct sun rays and this is summer. When the axis is tilted away from the sun, the NH receives less direct sun rays and this is winter.

Explain how organisms produced through sexual reproduction are different from those produced through asexual reproduction.
Each organism produced through sexual reproduction is genetically unique having a different combination of genes from each parent.
Each organism produced through asexual reproduction is identical to their parent.

What is the role of sunlight in photosynthesis?
Sunlight is required for photosynthesis to occur. The energy from the sunlight is captured and turned into glucose.
