Answer the following question given this paragraph: Neither positive ions nor negative ions are attracted to a nonpolar molecule. In fact, the alkanes undergo so few reactions that they are sometimes called paraffins, from the Latin parum affinis, meaning "little affinity. " Two important reactions that the alkanes do undergo are combustion and halogenation. Nothing happens when alkanes are merely mixed with oxygen (O2) at room temperature, but when a flame or spark provides the activation energy, a highly exothermic combustion reaction proceeds vigorously. For methane (CH4), the reaction is as follows:. Q: What happens when alkanes are mixed with oxygen at room temperature? A:

OPTIONS:
- single replacement
- redox
- combustion
- no reaction

Answer: no reaction

Problem: OPTIONS:
- watt
- rads
- decibel
- hertz
Q: Answer the following question given this paragraph: The frequency of sound waves is measured in hertz (Hz), or the number of waves that pass a fixed point in a second. Human beings can normally hear sounds with a frequency between about 20 Hz and 20,000 Hz. Sounds with frequencies below 20 hertz are called infrasound . Infrasound is too low-pitched for humans to hear. Sounds with frequencies above 20,000 hertz are called ultrasound . Ultrasound is too high-pitched for humans to hear. Q: The frequency of sound waves is measured in what unit? A:
Answer: hertz

Problem:OPTIONS:
- aerial species
- amphibious species
- terrestrial species
- aquatic species

Answer the following question given this paragraph: Overharvesting Overharvesting is a serious threat to many species, but particularly to aquatic species. There are many examples of regulated fisheries (including hunting of marine mammals and harvesting of crustaceans and other species) monitored by fisheries. Q: Overharvesting is a serious threat particularly to which species? A:
****
A: aquatic species

OPTIONS:
- photon
- quark
- isotope
- ion
ion

Answer the following question given this paragraph: Parasitism is a symbiotic relationship in which one species (the parasite ) benefits while the other species (the host ) is harmed. Many species of animals are parasites, at least during some stage of their life. Most species are also hosts to one or more parasites. Q: What is the term for a symbiotic relationship in which the parasite benefits while the host is harmed? A:
OPTIONS:
- infection
- reciprocity
- pathology
- parasitism

Answer: parasitism
