Problem:OPTIONS:
- choanocyte plants
- vascular plants
- photoreactive plants
- nonvascular plants

Answer the following question given this paragraph: Nonvascular plants include mosses, liverworts, and hornworts. They are the only plants with a life cycle in which the gametophyte generation is dominant. Figure below shows the life cycle of moss. The familiar, green, photosynthetic moss plants are gametophytes. The sporophyte generation is very small and dependent on the gametophyte plant. Q: Mosses, liverworts, and hornworts are examples of what type of plant in which gametophyte generation is dominant? A:
****
A: nonvascular plants

Answer the following question given this paragraph: O 3(g) O(g) + O 2(g) The reactive oxygen atoms recombine with molecular oxygen to complete the ozone cycle. The presence of stratospheric ozone decreases the frequency of skin cancer and other damaging effects of ultraviolet radiation. It has been clearly demonstrated that chlorofluorocarbons, CFCs (known commercially as Freons), which were present as aerosol propellants in spray cans and as refrigerants, caused depletion of ozone in the stratosphere. This occurred because ultraviolet light also causes CFCs to decompose, producing atomic chlorine. The chlorine atoms react with ozone molecules, resulting in a net removal of O3 molecules from stratosphere. This process is explored in detail in our coverage of chemical kinetics. There is a worldwide effort to reduce the amount of CFCs used commercially, and the ozone hole is already beginning to decrease in size as atmospheric concentrations of atomic chlorine decrease. While ozone in the stratosphere helps protect us, ozone in the troposphere is a problem. This ozone is a toxic component of photochemical smog. The uses of ozone depend on its reactivity with other substances. It can be used as a bleaching agent for oils, waxes, fabrics, and starch: It oxidizes the colored compounds in these substances to colorless compounds. It is an alternative to chlorine as a disinfectant for water. Q: The presence of what stratospheric gas layer decreases the frequency of skin cancer and other damaging effects of ultraviolet radiation? A:
OPTIONS:
- plasma
- cumulonimbus
- smog
- ozone
ozone

Answer the following question given this paragraph: During a thunderstorm, some parts of a thunderhead become negatively charged. Other parts become positively charged. The difference in charge creates lightning. Lightning is a huge release of electricity. Lightning can jump between oppositely charged parts of the same cloud, between one cloud and another, or between a cloud and the ground. You can see lightning in Figure below . Lightning blasts the air with energy. The air heats and expands so quickly that it explodes. This creates the loud sound of thunder . Q: What causes lightning during a thunderstorm? A:
OPTIONS:
- difference in wind
- difference in elevation
- difference in temperature
- difference in charge

Answer: difference in charge

Q: What do you call a science that aims to find solutions to practical problems? A:
OPTIONS:
- applied experience
- experimental science
- evolved science
- applied science
Answer: applied science
