Here is data from a study on second-hand smoke and lung cancer: Ten thousand (10,000) people that have lived with smokers for at least 10 years were studied. Seven hundred and forty (740) of
these people got lung cancer. Therefore, 7.4% of these people got lung cancer. Their conclusion is
second-hand smoke causes lung cancer. Do you agree or disagree with their conclusion? Explain
your answer by using ONLY the data provided in this question.

I disagree

Explanation:

The data doesn't give enough info, were the people who lived with smokers, smokers as well? or were they clean off nicotine.  Also the data presents itself stating the fact that second hand smoke will defiantly cause Lung cancer when in reality (as the data shows with only 7.4%) only a small percentage is affected by the smoke.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
