Answer the following question given this paragraph: Most nonmetals are poor conductors of heat. In fact, they are such poor conductors of heat that they are often used for insulation. For example, the down filling in this sleeping bag is full of air, which consists primarily of the nonmetal gases oxygen and nitrogen. These gases prevent body heat from escaping to the cold outside air. Q: What are the three most common elements in the air we breathe? A:
****
A: nitrogen, oxygen and argon

Answer the following question given this paragraph: Cellulose is a compound found in plants. The chief component of cellulose is carbon. Cellulose is one of many carbon-based compounds that make up living things. In fact, carbon-based compounds are the most common type of compound on Earth. More than 90 percent of all known compounds contain carbon. Do you know why carbon is found in so many compounds? Read on to find out. Q: What are the most common types of compounds found on earth? A:
OPTIONS:
- sodium - based compounds
- ionic compounds
- hydrogen-based compounds
- carbon-based compounds
carbon-based compounds

Answer the following question given this paragraph: Pillow lava is created from lava that enters the water. The volcanic vent may be underwater. The lava may flow over land and enter the water ( Figure below ). Once in the water, the lava cools very quickly. The lava forms round rocks that resemble pillows. Pillow lava is particularly common along mid-ocean ridges. Q: Lava that enters the water is called what? A:
OPTIONS:
- lava flow
- magma runoff
- saltwater lava
- pillow lava

Answer: pillow lava

Question: Answer the following question given this paragraph: 2.2 Water Water has many properties that are critical to maintaining life. It is polar, allowing for the formation of hydrogen bonds, which allow ions and other polar molecules to dissolve in water. Therefore, water is an excellent solvent. The hydrogen bonds between water molecules give water the ability to hold heat better than many other substances. As the temperature rises, the hydrogen bonds between water continually break and reform, allowing for the overall temperature to remain stable, although increased energy is added to the system. Water's cohesive forces allow for the property of surface tension. All of these unique properties of water are important in the chemistry of living organisms. The pH of a solution is a measure of the concentration of hydrogen ions in the solution. A solution with a high number of hydrogen ions is acidic and has a low pH value. A solution with a high number of hydroxide ions is basic and has a high pH value. The pH scale ranges from 0 to 14, with a pH of 7 being neutral. Buffers are solutions that moderate pH changes when an acid or base is added to the buffer system. Buffers are important in biological systems because of their ability to maintain constant pH conditions. Q: An excellent solvent that holds heat well and allows hydrogen bonds, what substance has many properties critical to life? A:
OPTIONS:
- liquid
- blood
- plasma
- water
Answer: water

input with options: Answer the following question given this paragraph: The sympathetic division controls internal organs and glands during emergencies. It prepares the body for fight or flight ( Figure below ). For example, it increases the heart rate and the flow of blood to the legs, so you can run away from danger. Q: What prepares the body for fight or flight during emergencies? A:
OPTIONS:
- abnormal division
- metabolic response
- adrenal mechanism
- sympathetic division
output: sympathetic division

Problem: OPTIONS:
- gaseous
- ovarian
- uterine
- fallopian
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? A:
Answer:
fallopian
