Answer: Option (A)

Explanation: The interior of the earth radiates a huge amount of energy due to the presence of molten heavy materials namely iron and nickel. This heat energy drives the plates to move over the mantle.

This radiated energy plays a significant role in increasing the temperature at the lower atmosphere. At the lower atmosphere majority of the air is concentrated due to its high density and are attached to the ground because of gravity.

This radiated heat energy then heats up this air particles that leads to an increasing air pressure and temperature.

The heat from the sun is less significant in warming up the air in the lower atmospheric region.

Thus, the correct answer is option (A).

All of the following contribute to the movement of venous blood EXCEPT A. ventricular systole B. pressure changes in the thorax
AlladinOne [14]

Answer:  B. pressure changes in the thorax

Explanation:

The veins are the blood vessels which returns the deoxygenated blood from all the tissues and cells of the body back to the heart. The ventricular systole, venous valves, activity of the skeletal muscles and neural control over venoconstriction all influence the movement of the blood in the venous.

The pressure changes in the thorax occurs due to inspiration and expiration. During the process of inspiration, the diaphragm below the lungs contracts and moves downward while the muscles of the ribs pulls downward. When the size of the thoracic cavity increase the air pressure inside the cavity decreases and vice-versa. The pressure inside the thoracic cavity is not related with the movement of the venous blood as it regulates the exchange of the gases not the blood.

melamori03 [73]

Explanation:

Chewing, grinding, pressing, salivating

When we chew, the tongue and the cheeks work together to constantly move the food between the teeth so that it can be chewed. The tongue presses the crushed food against the palate and moves this bolus, which is then ready to be swallowed, to the throat.
