Answer the following question given this paragraph: Radioactive decay is the breakdown of unstable elements into stable elements. To understand this process, recall that the atoms of all elements contain the particles protons, neutrons, and electrons. Q: What is the breakdown of unstable elements into stable elements called? Choices: - initial decay - thermal decay - radioactive decrease - radioactive decay A:
radioactive decay
Answer the following question given this paragraph: Q: No chemical process on the planet can match the output of what process? Choices: - sexual reproduction - glycolysis - pollination - photosynthesis A:
photosynthesis
Q: Answer the following question given this paragraph: Approximate colors are shown, along with pKin values and the pH range over which the color changes. It is important to be aware that an indicator does not change color abruptly at a particular pH value; instead, it actually undergoes a pH titration just like any other acid or base. As the concentration of HIn decreases and the concentration of In increases, the color of the solution slowly changes from the characteristic color of HIn to that of In. As we will see in Section 16.6 "Buffers", the [In]/[HIn] ratio changes from 0.1 at a pH one unit below pKin to 10 at a pH one unit above pKin. Thus most indicators change color over a pH range of about two pH units. We have stated that a good indicator should have a pKin value that is close to the expected pH at the equivalence point. For a strong acidstrong base titration, the choice of the indicator is not especially critical due to the very large change in pH that occurs around the equivalence point.

Choices: - phalanges - renal - glandular - plantar A:
A: plantar
Question: Answer the following question given this paragraph: Tides are daily changes in the level of ocean water. They are caused mainly by the pull of the Moon's gravity on Earth and its oceans. The Sun's gravity also influences tides. Q: What are daily changes in the level of ocean water called? Choices: - waves - floods - currents - tides A:
Answer: tides

Answer the following question given this paragraph: Unless an animal cell (such as the red blood cell in the top panel) has an adaptation that allows it to alter the osmotic uptake of water, it will lose too much water and shrivel up in a hypertonic environment. If placed in a hypotonic solution, water molecules will enter the cell, causing it to swell and burst. Plant cells (bottom panel) become plasmolyzed in a hypertonic solution, but tend to do best in a hypotonic environment. Water is stored in the central vacuole of the plant cell. Q: What kind of solution might cause animal cells to burst? Choices: - Acid Solution - monatomic - eutrophic - hypotonic A:
**Answer**
hypotonic
Answer the following question given this paragraph: Breakwaters are structures that protect the coast like barrier islands. Groins are structures that help prevent longshore drift from eroding a beach. Q: What are structures that protect the coast like barrier islands called? Choices: - domes - dunes - fortresses - breakwaters A:
breakwaters
