Q: Answer the following question given this paragraph: We can also consider the reverse reaction in the above equation. In that reaction, the ammonium ion donates a proton to the hydroxide ion. The ammonium ion is a Brnsted-Lowry acid, while the hydroxide ion is a Brnsted-Lowry base. Most Brnsted-Lowry acid-base reactions can be analyzed in this way. There is one acid and one base as reactants, and one acid and one base as products. Q: The ammonium ion is what type of acid? A: | OPTIONS:
- normal -lowry
- kaon - lowry
- oxidized - lowry
- brnsted-lowry
A: brnsted-lowry

Q: Answer the following question given this paragraph: Q: What two microorganisms have different membrane lipids? A: | OPTIONS:
- microsporidia and bacteria
- mesozoic and bacteria
- algae and bacteria
- archaea and bacteria
A: archaea and bacteria

Q: Answer the following question given this paragraph: Plants are complex organisms with tissues organized into organs. Q: Plants are complex organisms with tissues organized into what? A: | OPTIONS:
- carbons
- systems
- families
- organs
A: organs

Q: Answer the following question given this paragraph: Lakes, ponds, streams, springs, and wetlands are fresh water bodies. The organisms that live in them are part of freshwater ecosystems. These ecosystems vary by temperature, pressure (in lakes), and the amount of light that penetrates. The type of plants that grow in these ecosystems varies. Q: Lakes, ponds, streams, springs, and wetlands are? A: | OPTIONS:
- salt water bodies
- man-made structures
- land formations
- fresh water bodies
A: fresh water bodies
