Answer the following question given this paragraph: Water is the main ingredient of many solutions. A solution is a mixture of two or more substances that has the same composition throughout. Some solutions are acids and some are bases. To understand acids and bases, you need to know more about pure water. In pure water (such as distilled water), a tiny fraction of water molecules naturally breaks down to form ions. An ion is an electrically charged atom or molecule. The breakdown of water is represented by the chemical equation. Q: What is the term for a mixture of two or more substances that has the same composition throughout? Choices: - fluid - simple liquid - structure - solution A:
solution
Answer the following question given this paragraph: Cellulose is another complex carbohydrate that is a polymer of glucose. However, glucose molecules are bonded together differently in cellulose than they are in starches. Cellulose molecules bundle together to form long, tough fibers, as you can see in the Figure below . Have you ever eaten raw celery? If you have, then you probably noticed that the stalks contain long, stringy fibers. The fibers are mostly cellulose. Cellulose is the most abundant biochemical compound. It makes up the cell walls of plants and gives support to stems and tree trunks. Cellulose also provides needed fiber in the human diet. We can't digest cellulose, but it helps keep food wastes moving through the digestive tract. Q: What human bodily function does cellulose help with? Choices: - stops food wastes - sleep - reproduction - moves food wastes A:
moves food wastes
Q: Answer the following question given this paragraph: A day or two after an ovary releases an egg, the egg may unite with a sperm. Sperm are deposited in the vagina during sexual intercourse. They propel themselves through secretions in the uterus and enter a fallopian tube. This is where fertilization normally takes place. Q: Sperm propel themselves through secretions in the uterus and enter what tube? Choices: - gaseous - ovarian - uterine - fallopian A:
A: fallopian
Question: Answer the following question given this paragraph: Physical science is the study of matter and energy. It includes the sciences of chemistry and physics. Most careers in physical science require a 4-year college degree in one of these fields. Some careers require more advanced education as well. For example, an astronaut might have a master's degree or even a doctoral degree. Q: What branch of science is the study of matter and energy? Choices: - environmental science - Chemistry - Thermodynamics - physical science A:
Answer: physical science

Answer the following question given this paragraph: Long Bones A long bone is one that is cylindrical in shape, being longer than it is wide. Keep in mind, however, that the term describes the shape of a bone, not its size. Long bones are found in the arms (humerus, ulna, radius) and legs (femur, tibia, fibula), as well as in the fingers (metacarpals, phalanges) and toes (metatarsals, phalanges). Long bones function as levers; they move when muscles contract. Q: What type of function does the long bone perform? Choices: - acts as pivot - works as piston - acts as pulley - work as lever A:
**Answer**
work as lever
