Hello there!!!
I'm inclined to think that the answer is A. These are products, so they can't really be reactants (unless the equation is reversible, which this is not). Cellular respiration is the process of the cells releasing the waste that they do not need. So A seems to be the logical choice.
Does this help you?
Wood will break down into peat, then will be compressed underground to make coal. Adding more compression will make diamonds.
Because a hypothesis is different from the research question, research is usually required before you make a hypothesis. A hypothesis is a prediction of the test that is about to incur. Without the research the people doing the test would not know what to be looking for or how to setup the test. Because of the reason;
I assume the answer is, after generating an idea from an observation.
Examples of nonrenewable resources include crude oil, natural gas, coal, and uranium. These are all resources that are processed into products that can be used commercially. For example, the fossil fuel industry extracts crude oil from the ground and converts it to gasoline.
I wasn't technically sure so i looked it up and found this "In a money summary, each word costs a
certain amount. Students are told how
much money they have to spend and how
much words will cost." So I would say that it is a the cost you have to pay for each word you use ( usally It would not apply to the words a, the and an) if you to write a certain type of paper. I hope this is of any help.
