Answer the following question given this paragraph: The fuel that burns in a combustion reaction is often a substance called a hydrocarbon. A hydrocarbon is a compound that contains only carbon (C) and hydrogen (H). Fossil fuels, such as natural gas, consist of hydrocarbons. Natural gas is a fuel that is commonly used in home furnaces and gas stoves (see Figure below ). The main component of natural gas is the hydrocarbon called methane (CH 4 ). The combustion of methane is represented by the equation:. Q: The fuel that burns in a combustion reaction in many fossil fuels such as natural gas that consists of carbon hydrogen is known as what? A:
OPTIONS:
- helium
- catalyst
- fossil
- hydrocarbon

Answer: hydrocarbon

Q: Answer the following question given this paragraph: The arthropod exoskeleton consists of several layers of cuticle. The exoskeleton prevents water loss and gives support and protection. It also acts as a counterforce for the contraction of muscles. The exoskeleton doesn't grow as the animal grows. Therefore, it must be shed and replaced with a new one periodically through life. This is called molting . Q: What part of an animal helps to prevent water loss and gives support and protection? A:

OPTIONS:
- membrane
- cuticle
- backbone
- exoskeleton

A: exoskeleton

Answer the following question given this paragraph: Steps in Glycolysis The 10 reactions of glycolysis, summarized in Figure 20.16 "Glycolysis", can be divided into two phases. In the first 5 reactionsphase Iglucose is broken down into two molecules of glyceraldehyde 3-phosphate. In the last five reactionsphase IIeach glyceraldehyde 3-phosphate is converted into pyruvate, and ATP is generated. Notice that all the intermediates in glycolysis are phosphorylated and contain either six or three carbon atoms. Figure 20.16 Glycolysis. Q: What does glycolysis generate in phase ii? A:
OPTIONS:
- amino acids
- dna
- adp
- atp
atp
