Hi Ishika

The correct option is 1) 'Na+ reabsorption requires energy'.

Explanation

The nephron is  composed of Bowman's capsule, proximal convoluted tubule, Loop of Henle and distal convoluted tubule . In distal convolutes tubule reabsorption of Na+ and water takes place which is active process i.e requires energy.

Thus, the

Hi Ishika,

Option 3. Less is correct.

Glomerular filtrate contains less glucose in comparison to plasma because most of the glucose is readily reabsorbed in the proximal convolutes tubule (PCT) part of the nephron.

So, Glomerular filtrate contains 'Less' glucose in comparison to plasma.

Thankyou

Hi

The correct option is 3) SA Node.

Explanation :- SA node i.e Sino-atrial node generates action potentials   and therefore, it sets the pace of the activities of the heart. Hence, it is generates heartbeat and thus also called as the cardiac pacemaker
