Answer the following question given this paragraph: Because of human activities, there is more carbon dioxide in the atmosphere today than in the past hundreds of thousands of years. Burning fossil fuels and has released great quantities of carbon dioxide into the atmosphere. Cutting forests and clearing land has also increased carbon dioxide into the atmosphere because these activities reduce the number of autotrophic organisms that use up carbon dioxide in photosynthesis. In addition, clearing often involves burning, which releases carbon dioxide that was previously stored in autotrophs. Q: Cutting forests and clearing land has also increased the amount of what in the atmosphere? A:

OPTIONS:
- oxygen
- smog
- pesticides
- carbon dioxide

Answer: carbon dioxide

Problem: OPTIONS:
- blood
- sodium
- plasma
- water
Q: Answer the following question given this paragraph: When HCl is dissolved into water, it is called hydrochloric acid. Ionic compounds and some polar compounds are completely broken apart into ions and thus conduct a current very well. A strong electrolyte is a solution in which a large fraction of the dissolved solute exists as ions. Q: Hydrochloric acid is formed when hcl is dissolved into what? A:
Answer: water

Problem:OPTIONS:
- rust
- copper alloy
- iron oxide
- copper oxide

Answer the following question given this paragraph: A: Another example of matter changing color is a penny changing from reddish brown to greenish brown as it becomes tarnished. The color change indicates that a new chemical substance has been produced. Copper on the surface of the penny has combined with oxygen in the air to produce a different substance called copper oxide. Q: What substance is created when a copper turns from reddish brown to greenish brown? A:
****
A: copper oxide

Problem:OPTIONS:
- b cells
- natural killer cells
- control cells
- memory cells

Answer the following question given this paragraph: After an infection has been brought under control, most cytotoxic T cells die off. However, a few remain as memory cells. If the same pathogen enters the body again, the memory cells mount a rapid immune response. They quickly produce many copies of cytotoxic T cells specific to the antigen of that pathogen. Q: After an infection has been brought under control and most cytotoxic t cells die off, a few remain as what? A:
****
A:
memory cells
