Answer the following question given this paragraph: Why does the pressure of a gas increase as it gets warmer? Particles of a gas are constantly moving and bumping into things. The force of the collisions is measured by pressure. Pressure is the amount of force exerted on a given area, such as pounds of force per square inch. When gas particles heat up and gain energy, they move faster. This causes more collisions and greater pressure. Therefore, heating particles of gas in a closed space causes the pressure of the gas to increase. Explore the behavior of gas particles at different temperatures at the following URL. Change the temperature of the gas and watch what happens to its particles. Q: If everything else stays the same in a system with a gas in it, and the gas gets warmer, what will happen to its pressure, generally? A:
****
A: it increases

Answer the following question given this paragraph: Lipids are one of four classes of biochemical compounds, which are compounds that make up living things and carry out life processes. (The other three classes of biochemical compounds are carbohydrates, proteins, and nucleic acids. ) Living things use lipids to store energy. Lipids are also the major components of cell membranes in living things. Types of lipids include fats and oils. Q: Name the missing call of biochemical compound: carbohydrates, proteins, nucleic acids. A:
OPTIONS:
- enzymes
- microorganisms
- tissues
- lipids
lipids

Answer the following question given this paragraph: Q: What are responsible for the bending movements of the organelle? A:
OPTIONS:
- sporozoans
- muscles
- pores
- dyneins

Answer: dyneins

Question: Answer the following question given this paragraph: Although the idea that Earth is a magnet is centuries old, the discovery of why Earth is a magnet is a relatively new. In the early 1900s, scientists started using seismographic data to learn about Earth's inner structure. A seismograph detects and measure earthquake waves. Evidence from earthquakes showed that Earth has a solid inner core and a liquid outer core (see the Figure below ). The outer core consists of molten metals, mainly iron and nickel. Scientists think that Earth's magnetic field is generated by the movement of charged particles through these molten metals in the outer core. The particles move as Earth spins on its axis. The video at the URL below takes a closer look at how this occurs. Q: What device detects and measuresee earthquake waves? A:
OPTIONS:
- stenograph
- polygraph
- sphygmomanometer
- seismograph
Answer: seismograph

input with options: Answer the following question given this paragraph: Electrons have virtually no mass, but protons and neutrons have a lot of mass for their size. As a result, the nucleus has virtually all the mass of an atom. Given its great mass and tiny size, the nucleus is very dense. If an object the size of a penny had the same density as the nucleus of an atom, its mass would be greater than 30 million tons! You can learn more about the size and mass of the nucleus at this URL:. Q: Where does most of the mass for an atom reside? A:
OPTIONS:
- electrons
- neutrons
- protons
- nucleus
output: nucleus

Problem: OPTIONS:
- carbonite
- copper
- lead
- graphite
Q: Answer the following question given this paragraph: Graphite is a form of carbon in which carbon atoms are arranged in layers. Bonds are strong between carbon atoms within each layer but relatively weak between atoms in different layers. The weak bonds between layers allow the layers to slide over one another. This makes graphite relatively soft and slippery. It is used as a lubricant. It also makes up the "lead" in pencils. Q: What layered form of carbon is used as a lubricant and in pencils? A:
Answer:
graphite
