Explanation:
food first goes into the small intestine which is part b before the large intestine which is part a
Image shows a lake, a factory, a cloud in the sky, a cow, dead organisms, a tree, and the sun. An arrow from the sun to the tree is labeled A. An arrow from the sky to the tree is labeled B. The sky is labeled C above the cloud. The letter D is in the air and an arrow points from it down to dead organisms. An arrow points from dead organisms to the ground labeled E. An arrow points from the cow into to the sky labeled F. An arrow points from the factory to the sky labeled G. An arrow from the sky to the lake is labeled H above the lake.
Using the diagram above, match the description to the corresponding location in the carbon cycle model. Provide the letter only.
Carbon dioxide is converted to sugar used for food.
Carbon trapped in fossil fuels is converted to carbon dioxide.
Organic carbon is converted to fossil fuels.
Carbon dioxide is converted to carbonates.
Sugar is broken down and converted to carbon dioxide.

Part Two
Images shows a lake labeled carbonates in water, a cow labeled animal respiration, a tree labeled photosynthesis, a factory labeled factory emissions, the sun labeled sunlight, a cloud labeled carbon dioxide in atmosphere, another tree labeled plant respiration, an arrow from organic carbon to dead organism, and fossils and fossil fuels. Arrows are labeled as follows: A from the sunlight to photosynthesis, B from carbon dioxide in atmosphere to photosynthesis, C from factory emissions to carbon dioxide in atmosphere, D from carbon dioxide in atmosphere to carbonates in water, E from dead organisms to fossils and fossil fuels, and F from plant respiration to the sky.
Using the diagram above, answer the following questions:
True or False. The arrow labeled C represents a transfer of chemical energy to mechanical energy. Explain why this is true or false.
True or False. The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false.
Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected?
Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected.
Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.
Answer:
A - 1. Carbon dioxide is converted to sugar used for food (this is process of phosynthesis).
G - 2. Carbon trapped in fossil fuels is converted to carbon dioxide (this is combustion of fuel).
E - 3. Organic carbon is converted to fossil fuels.
H - 4. Carbon dioxide is converted to carbonates.
F - 5. Sugar is broken down and converted to carbon dioxide (this is breathing).

Which statement accurately describes in terms of energy what happens when water turns to steam?
The water releases energy which causes chemical bonds to break, changing water to steam.
The water releases energy which causes the water molecules to have less kinetic and potential energy, changing their configuration from liquid to gas.
The water absorbs energy which causes the water molecules to have more kinetic and potential energy, changing their configuration from a liquid to a gas.
The water absorbs energy which causes chemical bonds to break, changing water to steam.

Evan sees a lunar eclipse one night. When he briefly observes the Moon, about half of it is bright and the other half is dark. He wonders what phase the Moon is in during this event.
Evan decides to use a model of the Sun-Earth-Moon system to determine the Moon's phase during a lunar eclipse. He uses a light bulb to represent the Sun and its light, a softball to represent the Earth, and a golf ball to represent the Moon.
Which diagram shows how Evan should arrange his model to investigate a lunar eclipse?
Answer:
the top right picture
Explanation:
the moon is behind the earth when a lunar eclipse happens

(GIVING BRAINLYIST) Jenna notices that the speed of the wind has increased throughout the day. What is causing the faster wind?
There has been no precipitation.
The difference in air pressure has decreased.
The difference in air pressure has increased.
The direction of the wind has changed to the south.
Answer: C. The difference in air pressure has increased.
The gases that move from high-pressure areas to low-pressure areas cause the high winds that we experience today. The bigger the difference between the pressures, the faster the air will move from the high to the low pressure.
Explanation:
Hope this helps =)

Explanation:
The contents of the left side have moved down, this is able to be told because the "a" used to be in the same position all the way across. The left side moved down, and the right side moved up to create what is seen on the chart.
Physical science studies the relationships between __________, ___________, and ___________.
How does the ozone "hole" affect humans?
a. Some humans are exposed to lower levels of ultraviolet radiation.
b. Humans aren't affected by the "hole" in the ozone layer.
c. Some humans are exposed to higher levels of ultraviolet radiation.
d. Some of the ultraviolet radiation on Earth goes back into space, so humans aren't exposed to as much.
Answer:
A
Explanation:
Some humans below the hole are exposed to more UV due to the missing ozone (which absorbs UV)

What action-reaction forces are involved when a rocket engine fires? Why doesn't a rocket need air to push on?
Answer:
The action force is the rocket pushing out the "hot" gases produced by the engine. The reaction force is the hot gas pushing back on the rocket propelling it into outer space.
And....
The reaction force is the hot gas pushing back on the rocket propelling it into outer space. There is no need for air to push on because the hot gases produced by the rocket allow the action and reaction forces to operate. These two forces are equal and opposite (action-reaction) forces.

The diagram shows the process of photosynthesis. Which part represents an autotroph?
Answer:
A and B
Explanation:
The Sun's Energy is stored in the chemical bonds that make up food. Some forms of life make their own food. These are the Autotrophs.
Plants are autotrophs, which means they produce their own food.
For most activities, the ________ makes a handy frame of reference.
