Answer the following question given this paragraph: Potential energy due to the position of an object above Earth is called gravitational potential energy. Like the leaves on trees, anything that is raised up above Earth's surface has the potential to fall because of gravity. You can see examples of people with gravitational potential energy in Figure below . Q: What is the term for potential energy due to the position of an object above earth? Choices: - gravitational pull energy - gravitational indication energy - gravitational recovery energy - gravitational potential energy A:
gravitational potential energy

Answer the following question given this paragraph: An object will not change its state of motion (i. e. , accelerate) unless a net force acts on it. Equal and oppositely directed forces do not produce acceleration. Q: Equal and oppositely directed forces produce what kind of acceleration? Choices: - steady acceleration - greater acceleration - faster acceleration - no acceleration A:
(Answer)
no acceleration
Ques: Answer the following question given this paragraph: The nitrogen cycle moves nitrogen back and forth between the atmosphere and organisms. Bacteria change nitrogen gas from the atmosphere to nitrogen compounds that plants can absorb. Other bacteria change nitrogen compounds back to nitrogen gas, which re-enters the atmosphere. Q: The nitrogen cycle moves nitrogen back and forth between the atmosphere and what? Choices: - Ocean - Ozone Layer - sediments - organisms A:
Ans: organisms
(Q).
Answer the following question given this paragraph: There are billions of bacteria inside the human digestive tract. They help us digest food. They also make vitamins and play other important roles. We use bacteria in many other ways as well. For example, we use them to:. Q: Billions of what inside the human digestive tract help us digest food, make vitamins and play other important roles? Choices: - neurons - viruses - red blood cells - bacteria A:
(A).
bacteria
Ques:Answer the following question given this paragraph: The Sun produces far more energy than humans can use. The Sun is also the source of most of the energy we use. Fossil fuels and wind energy, for example, originate with the Sun. So why don't we get all our energy from the Sun? For one reason, it's not always practical. Q: What is the source of most of the energy used? Choices: - the Earth - fossil fuels - the Moon - the sun A:

Ans:the sun
Question: Answer the following question given this paragraph: Not all diseases are contagious. A disease that is not contagious is called a noninfectious disease. These diseases are not caused by pathogens. Instead, they are likely to have causes such as lifestyle factors, environmental toxins, or gene mutations. Common types of noninfectious diseases include cancer, diabetes, and immune system diseases. Q: What is the term for a disease that is not contagious? Choices: - uncultured disease - common cold - benign - noninfectious disease A:
Answer:
noninfectious disease
