The correct answer is "thoracic duct".
The thoracic duct (also called as the left lymphatic duct or the alimentary duct) is the structure wherein most of the lymph in the drained from the lymphatic vessels goes to this structure. In the thoracic duct, lymph flows up to the level of the brachiocephalic vein where lymph returns to the venous circulation.
The statement that correctly describes the relation in the question is ; ( A ) As wavelength decreases, frequency increases, energy increases and the speed remains the same.
The Frequency of a wave travelling in a medium is directly proportional to the energy produced by the wave and inversely proportional to the wavelength of the wave.
Changes in the wavelength and frequency of a wave has no effect on the wave speed. but has an effect on the energy produced by the wave. therefore the wave speed remains constant regardless of the changes in wavelength and frequency
Hence we can conclude that As wavelength decreases, frequency increases, energy increases and the speed remains the same.

Answer: Sympathetic Nervous System.
Explanation:
The sympathetic nervous system is part of the autonomic nervous system. The sympathetic nervous system activates what is often termed the fight or flight response. The sympathetic nervous system directs the body's rapid involuntary response to dangerous or stressful situations. A flash flood of hormones boosts the body's alertness and heart rate, sending extra blood to the muscles. Breathing quickens, delivering fresh oxygen to the brain, and an infusion of glucose is shot into the bloodstream for a quick energy boost. The sympathetic nervous system allows animals to make quick internal adjustments and react without having to think about it.
"Bedding is the separation of sediments into layers that differ from one another in texture, composition, color, or weathering characteristics".
Option (b);
<u>EXPLANATION: </u>
Sediments mean the matter that gets accumulated in one place. Sedimentary rocks are the results of the rock due to the accumulation of small particles that get weathered from rocks or erosion over time. They get accumulated either on the bottom of the sea level or earth's surface and thus the sediment rocks are formed.
These layers of sediments that are created based on difference in their shape, size, color and composition results it in bedding.The size of rocks in bedding ranges from several millimetres to centimetres and it sometimes results in a meter thick.
