Answer the following question given this paragraph: Like other arthropods, insects have three body segments and many jointed appendages. The abdomen contains most of the internal organs. Six legs are attached to the thorax. There are several appendages on the insect's head:. Q: Where are most of the organs contained in insects? A:
OPTIONS:
- head
- appendages

Answer: light

Question: Answer the following question given this paragraph: dissociated ions. It is a dynamic equilibrium because acid and base molecules are constantly dissociating into ions and reassociating into neutral molecules. The pH scale is a scale used to express the concentration of hydrogen ions in solution. A neutral solution, neither acidic nor basic, has a pH of 7. Acidic solutions have a pH lower than 7, while basic solutions have a pH higher than 7. Buffers are solutions that resist dramatic changes in pH when an acid or a base is added to them. They contain a weak acid and a salt of that weak acid, or a weak base and a salt of that weak base. When a buffer is present, any strong acid reacts with the anion of the salt, forming a weak acid and minimizing the presence of hydrogen ions in solution. Any strong base reacts with the weak acid, minimizing the amount of additional hydroxide ions in solution. However, buffers only have limited capacity; there is a limit to the amount of strong acid or strong base any given amount of buffer will react with. Q: The ph scale is a scale used to express the concentration of hydrogen ions in solution. a neutral solution, neither acidic nor basic, has a ph of what? A:
OPTIONS:
- 6
- 0
- 8
- 7
Answer: 7

Q: Answer the following question given this paragraph: Physical changes are changes in the physical properties of matter but not in the makeup of matter. An example of a physical change is glass breaking. Q: Glass breaking is an example of what type of change that doesn't affect the makeup of matter? A:

OPTIONS:
- reversible

A: physical

Answer the following question given this paragraph: Figure 41.2 Cells placed in a hypertonic environment tend to shrink due to loss of water. In a hypotonic environment, cells tend to swell due to intake of water. The blood maintains an isotonic environment so that cells neither shrink nor swell. (credit: Mariana Ruiz Villareal). Q: An environment in which cells neither sink nor swell is known as what? A:
OPTIONS:
- pressured environment
- electrolyte environment
- exothermic environment
- isotonic environment
isotonic environment
