Answer the following question given this paragraph: Some of the pollutants from fossil fuels can be filtered out of exhaust before it is released into the air ( Figure below ). Other pollutants can be changed to harmless compounds before they are released. Two widely used technologies are scrubbers and catalytic converters. Q: Scrubbers and catalytic converters are examples of technologies that change what into harmless compounds? Choices: - contaminants - toxins - mutations - pollutants A:
pollutants
Answer the following question given this paragraph: Normally blood needs to flow freely through our arteries. Plaque in an artery can restrict the flow of blood. As you can probably imagine, this is not an ideal situation. And eating right, exercising, and not smoking can help keep your arteries healthy.

Q: Answer the following question given this paragraph: Mollusks reproduce sexually. Most species have separate male and female sexes. Gametes are released into the mantle cavity. Fertilization may be internal or external, depending on the species. Fertilized eggs develop into larvae. There may be one or more larval stages. Each one is different from the adult stage. Mollusks (and annelids) have a unique larval form called a trochophore. It is a tiny organism with cilia for swimming. Q: The trochophre, a unique larval form, is found in the life cycle of which animal classification. Choices: - eels - coral - sharks - mollusks A:
A: mollusks
Question: Answer the following question given this paragraph: Any organic material can be made into electricity. But some materials are better than others. Wastes can be used, like almond shells. Biomass power is a great use of wastes. It's hard to use wastes as a consistent large scale source of energy though. Q: What kind of material that might otherwise go to a landfill can serve as the source of biomass power? Choices: - mechanical waste - microscopic waste - reactive waste - organic waste A:
Answer: organic waste

Answer the following question given this paragraph: Mutations are the key to species evolving. Lets say an organism "mutates" due to a new allele for a gene that determines coat color. There are, theoretically, only three outcomes of that mutation:. Q: What are the key to species evolving? Choices: - microbes - parasites - radiation - mutations A:
(Answer)
mutations
