Answer 1

Question

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.

Summary Introduction

Introduction:

Breathing is a mechanical process where the gases are exchanged between the lungs and the atmosphere. Breathing is the first step of respiration. Breathing occurs due to the changes in the pressure in the thorax or chest cavity of the body.

Expert Solution & Answer

Answer to Problem 1MCQ

Correct answer:

The main purpose of breathing in human beings is to exchange gases and to support the cellular aerobic respiration taking place in mitochondria.

Therefore, option (d) is correct.

Explanation of Solution

Reason for correct statement:

Breathing is the process of exchange of gases that is inhalation of oxygen gas and exhalation of carbon dioxide. The oxygen gas taken in by the breathing process is used in the aerobic respiration that takes place in mitochondria of the cell.

Option (d) is given as “Both a and b are correct”.

As, “breathing helps in the elimination of CO2 , and also supports the cellular aerobic respiration occurring in the mitochondria” is the right answer.

Hence, option (d) is correct.

Reasons for the incorrect statements:

Option (a), is given as “To eliminate CO2 ”.

The breathing process helps in the exhalation of the carbon dioxide gas from the body. As other statements given are also correct, Hence, it is a wrong answer.

Option (b), is given as “To support aerobic respiration in mitochondria”.

Breathing process helps in the intake of oxygen in the body that helped in the aerobic respiration occurring in the mitochondria. As other statements given are also correct, Hence, it is a wrong answer.

Option (c), is given as “To keep the respiratory surface dry”.

Breathing process does not play any role in the drying of the respiratory surface. Hence, it is a wrong answer.

Hence, options (a), (b), and (c), are incorrect.

Conclusion

Breath in means the inhaling of the oxygen gas while breath out means the exhaling of the carbon dioxide gas.

Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out. What type of bias is there in this study? If the company who makes the medication funds this research, what type of bias might exist in this research work?
