Answer the following question given this paragraph: Pollution that enters water at just one point is called point source pollution . For example, chemicals from a factory might empty into a stream through a pipe or set of pipes (see Figure below ). Pollution that enters in many places is called non-point source pollution . This means that the pollution is from multiple sources. With non-point source pollution, runoff may carry the pollution into a body of water. Which type of pollution do you think is harder to control?. Q: What is pollution that enters water at just one point called? Choices: - entry point pollution - point supply pollution - point supply pollution - point source pollution A:
point source pollution
Answer the following question given this paragraph: Pressure is defined as the amount of force acting on a given area. It measures how concentrated a force is. Q: What is defined as the amount of force acting on a given area? Choices: - resistance - density - power - pressure A:
pressure
Q: Answer the following question given this paragraph: Nitrogen oxides form when nitrogen and oxygen combine at high temperatures. This occurs in hot exhausts from vehicles, factories, and power plants. Q: What forms when nitrogen and oxygen combine at high temperatures? Choices: - oxygen oxide - ammonia oxide - carbon dioxide - nitrogen oxide A:
A: nitrogen oxide
Question: Answer the following question given this paragraph: Feldspar and quartz are the two most common silicates. In beryl, the silicate pyramids join together as rings. Biotite is mica. The silicate pyramids come together to create thin, flexible sheets. Compare the beryl and the biotite pictured below ( Figure below ). Q: What are the two most common silicates? Choices: - Analcime and Feldspar - Petalite and Quartz - Petalite and Analcime - feldspar and quartz A:
Answer: feldspar and quartz

Answer the following question given this paragraph: For molecules with more than two atoms, the molecular geometry must also be taken into account when determining if the molecule is polar or nonpolar. The Figure below shows a comparison between carbon dioxide and water. Carbon dioxide (CO 2 ) is a linear molecule. The oxygen atoms are more electronegative than the carbon atom, so there are two individual dipoles pointing outward from the C atom to each O atom. However, since the dipoles are of equal strength and are oriented in this way, they cancel each other out and the overall molecular polarity of CO 2 is zero. Q: What type of molecule is carbon dioxide (co2)? Choices: - non-linear - planar - filter - linear A:
**Answer**
linear
Q: Answer the following question given this paragraph: Q: Name the process that produces many copies of a certain gene. Choices: - gene diversion - gene multiplication - gene addition - gene cloning A:
A: gene cloning
