The reabsorption of glucose occurs primarily through the walls of the

A. glomerular capsule.

B. nephron loop.

C. proximal convoluted tubule.

D. distal convoluted tubule.

E. renal duct.

Answer:

C. proximal convoluted tubule.

Explanation:

Reabposrtion of glucose is supported by the nephron present in the kidney which mainatain body fluid homeostasis. It maintains extracellular body fluid volume stable  and also maintains the minerals and salts which are essential for body functioning. So, glucose reabsorption is a part of homeostasis.

The process of glucose reabsorption primarily starts through the walls of the  proximal convoluted tubule. proximal convoluted tubule are covered in microvillii and are extensive in length which increases the surface area for absorption. it also contain densly packed mitochndria which provide energy for efficient reabsorption. and then they are tranposrted to proximal straight tuble fo rfurther filteration.

Hence, the correct otpion is C.

Winds in our atmosphere are created as a result of which of the following processes?
shusha [124]

Answer:

<em>The correct option is D) Uneven heating of the air in the atmosphere</em>

Explanation:

Wind can simply be described as air which is moving or which is in motion. The uneven heating of the Earth's surface caused by the sun is the reason why winds occur. The difference in pressure of one area to another area causes the air to move and cause wind. The air tends to move from an area of higher pressure to an area of lower pressure and such is the movement of the wind.
