Directions: In each of the questions given below, there are two statements labelled as Assertion (A) and Reason (R). Mark your answer as per the codes provided below:

Reason (R): When we swallow, the back portion of our tongue covers the opening of the windpipe.

Detailed Solution for MCQ: Assertion and Reason - 2 - Question 4

Assertion (A) states that no food material normally enters the windpipe during swallowing, which is true because the process of swallowing involves the epiglottis covering the opening of the windpipe to prevent food or liquid from entering it.

Reason (R) explains this by highlighting that during swallowing, the back portion of our tongue covers the opening of the windpipe with the epiglottis, ensuring that food or drink is directed towards the esophagus rather than entering the windpipe.

Option (a) affirms that both A and R are true, and R provides the correct explanation for A, as the action of the tongue and epiglottis working together helps prevent food from entering the windpipe during swallowing.

Directions: In each of the questions given below, there are two statements labelled as Assertion (A) and Reason (R). Mark your answer as per the codes provided below:
Assertion (A): On the equinoxes, the day and night are equal all over the globe.
Reason (R): On the equinoxes, the position of the earth with respect to the sun is such that neither pole is inclined towards the sun.

Detailed Solution for MCQ: Assertion and Reason - 2 - Question 11

Assertion (A) is true. On the equinoxes, which occur twice a year (around March 20th and September 22nd), the day and night are approximately equal in duration all over the globe. This is because the Earth's axis is neither inclined toward nor away from the Sun, resulting in nearly equal sunlight distribution across the Earth.

Reason (R) is also true. During the equinoxes, the position of the Earth with respect to the Sun is such that neither pole is inclined toward the Sun. This lack of inclination is why the sunlight falls almost equally on both hemispheres, resulting in the equal length of day and night across the globe.

MCQ: Assertion and Reason - 2 - Question 14

Directions: In each of the questions given below, there are two statements labelled as Assertion (A) and Reason (R). Mark your answer as per the codes provided below:
Assertion (A): Areas near the Equator receive rainfall throughout the year.
Reason (R): High temperatures and high humidity cause conventional rain in most afternoons near the Equator.

Detailed Solution for MCQ: Assertion and Reason - 2 - Question 14

Assertion (A) is true. Areas near the Equator typically experience rainfall throughout the year. This region often encounters a consistent amount of precipitation due to its proximity to the Intertropical Convergence Zone (ITCZ), where air masses converge, leading to consistent upward motion and subsequent rainfall.

Reason (R) is also true. High temperatures and high humidity near the Equator create conditions favorable for the formation of conventional or convective rainfall. This happens when the warm air rises, cools, condenses, and forms clouds, often resulting in afternoon showers or thunderstorms.

Therefore, both assertions are accurate, and the reason (R) effectively explains why areas near the Equator receive rainfall throughout the year due to the prevailing weather conditions and the mechanisms behind rainfall in those regions.
