Q: Answer the following question given this paragraph: Consumers are organisms that depend on other organisms for food. They take in organic molecules by essentially "eating" other living things. They include all animals and fungi. (Fungi don't really "eat"; they absorb nutrients from other organisms. ) They also include many bacteria and even a few plants, such as the pitcher plant in Figure below . Consumers are also called heterotrophs. Heterotrophs are classified by what they eat:. Q: Consumers are organisms that depend on other organisms for what? Choices: - knowledge - reproduction - shelter - food A:
A: food
Question: Answer the following question given this paragraph: Blood from the lungs enters the left atrium of the heart. The left atrium pumps the blood to the left ventricle, which pumps it to the body. This loop is represented by the red arrows in Figure above . Q: Which side of the heart does blood from the lungs enter into? Choices: - right ventricle - left ventricle - right atrium - left atrium A:
Answer: left atrium

It includes all sounds with wave frequencies higher than 20,000 waves per second, or 20,000 hertz (Hz). Q: What do you call sound that has a wave frequency higher than the human ear can detect? Choices: - dynamic sound - supersonic sound - hypersonic sound - ultrasound A:
**Answer**
ultrasound
Answer the following question given this paragraph: Suppose that you wanted to know how many hydrogen atoms were in a mole of water molecules. First, you would need to know the chemical formula for water, which is H 2 O. There are two atoms of hydrogen in each molecule of water. How many atoms of hydrogen would there be in two water molecules? There would be 2 2 = 4 hydrogen atoms. How about in a dozen? In that case a dozen is 12 so 12 2 = 24 hydrogen atoms in a dozen water molecules. To get the answers, (4 and 24) you had to multiply the given number of molecules by two atoms of hydrogen per molecule. So to find the number of hydrogen atoms in a mole of water molecules, the problem could be solved using conversion factors. Q: H2o is the chemical formula for what? Choices: - glass - smog - salt - water A:
water
