8. Raoul ate a meal of oats before seeing his doctor. Oats are made of mostly starch molecules. Raoul feels tired, so his doctor gave him a test and found that Raoul's cells contained glucose molecules,
but they did not contain enough oxygen molecules. Does this explain why Raoul feels tired?
a
No, something else must be wrong because his cells have all the molecules they need.
b
Yes, his digestive system is breaking down starch molecules, but his respiratory system may
not be working properly.
С
Yes, his respiratory system is working, but his digestive system is not getting energy from
combining glucose molecules.
d
Yes, his digestive system is working, but his respiratory system is not breaking down
oxygen, so his body stopped making energy.

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.

listen, you cant how young you were.

"you didn't chose the stud life. the stud life chose you."

the right answer is c i just did the question.
