Answer the following question given this paragraph: During the water cycle, water occurs in three different states: gas (water vapor), liquid (water), and solid (ice). Many processes are involved as water changes state in the water cycle. Q: Water in its solid state is commonly known as what? Choices: - carbon dioxide - sea - glass - ice A:
ice
Answer the following question given this paragraph: Schrodinger's work on orbitals is the basis of the modern model of the atom, which scientists call the quantum mechanical model. The modern model is also commonly called the electron cloud model. That's because each orbital around the nucleus of the atom resembles a fuzzy cloud around the nucleus, like the ones shown in the Figure below for a helium atom. The densest area of the cloud is where the electrons have the greatest chances of being. Q: The modern model of the atom, which scientists call the quantum mechanical model, is based on what scientist's work on orbitals? Choices: - Sagan - Bohr - Newton - schrodinger A:
schrodinger
Q: Answer the following question given this paragraph: Ionic compounds contain ions of metals and nonmetals held together by ionic bonds. Ionic compounds do not form molecules. Instead, many positive and negative ions bond together to form a structure called a crystal. You can see an example of a crystal in Figure below . It shows the ionic compound sodium chloride. Positive sodium ions (Na + ) alternate with negative chloride ions (Cl - ). The oppositely charged ions are strongly attracted to each other. Q: What kind of bond doesn't form molecules, but instead forms crystals? Choices: - electron bonds - magnetic bonds - covalent bonds - ionic bonds A:
A: ionic bonds
Question: Answer the following question given this paragraph: Only mammals have hair. Hair is a fiber made mainly of the tough protein keratin. The cells of each hair are filled with keratin and no longer alive. The dead cells overlap each other, almost like shingles on a roof. They work like shingles as well, by helping shed water from hair. Q: What is the only class of animals that has hair? Choices: - reptiles - amphibians - birds - mammals A:
Answer: mammals

Answer the following question given this paragraph: Besides social insects, animals in many other species also cooperate. For example, in meerkat colonies, young female meerkats act as babysitters. They take care of the baby meerkats while their parents are out looking for food. Q: What do young female meerkats act as in colonies? Choices: - predators - defenders - midwives - babysitters A:
**Answer**
babysitters
Answer the following question given this paragraph: The small surface zone that has light is the photic zone. The entire rest of the ocean does not have light and is the aphotic zone. Q: What do you call the lightless part of the ocean? Choices: - Davy Jones' Locker - photic zone - photoreactive zone - aphotic zone A:
aphotic zone
