Question

You have the following known facts: Smoking causes accumulation of materials in the lungs, thereby decreasing oxygen-absorbing capability of the lungs. Long-term smoking causes more accumulation of materials in the lungs. Decreased lung capacity increases the workload of the heart. Which of the following hypotheses can you make from these observations_.

Answer 1

Answer:

B) long-term smokers have poorer health than non-smokers

Explanation:

The complete question is given below:

Smoking causes accumulation of materials in the lungs, thereby decreasing oxygen-absorbing capability of the lungs. Long term smoking causes more accumulation of materials in the lungs. Decreased lung capacity increases the workload of the heart. Which of the following hypothesis can you make form these observations?

A) people who never smoke will never develop lung problems

B) long-term smokers have poorer health than non-smokers

C) new smokers have poorer heart health than long-term smokers

D) people who occasionally smoke will never develop heart problems

E) stopping smoking eliminates lung problems within 2 years

• A hypothesis is a prediction that is made by observing a few things, however there are no existing scientific proof.
• A hypothesis proposes an explanation for an observed phenomena which could further b proved or rejected by using scientific methods.
• In the question, the facts are given from which it can be observed that smoking leads to poor functioning of the lungs and this further leads to increase of the workload of the heart, this implies that smoking has a negative health effect.
• From these observations, the hypothesis that can be made is long term smokers would have a poor health as compared to non smokers.
