Assertion and Reasoning
Assertion (A): Earth is the only planet known to have life.
Reasoning (R): Earth has no atmosphere which is a mixture of oxygen, nitrogen, and carbon dioxide.
Explanation:
This is an assertion and reasoning type question. Let's analyze the given statements one by one.
Assertion (A): Earth is the only planet known to have life.
The assertion is correct. To date, no other planet has been discovered that has life on it. Earth is unique in that it has the right combination of factors such as the right distance from the sun, a suitable atmosphere, and a magnetic field that protects it from solar winds, which makes it capable of sustaining life.
Reasoning (R): Earth has no atmosphere which is a mixture of oxygen, nitrogen, and carbon dioxide.
The reasoning is incorrect. Earth's atmosphere is a mixture of several gases including oxygen, nitrogen, and carbon dioxide. These gases provide the necessary conditions for life to exist on Earth. Oxygen, for instance, is essential for respiration, while nitrogen is needed for the synthesis of amino acids, the building blocks of proteins, which are essential for life.
Therefore, both the assertion and reasoning are true, but the reasoning does not explain the assertion. The correct answer is option (A).
