CHEMISTRY

The hormone that promotes sodium reabsorption in the kidneys is:

Aldosterone, a mineralocorticoid from the adrenal cortex, enhances sodium reabsorption in the distal tubules. This follows from latest NCERT 2026-27 principle explaining the concept clearly for NEET students in simple steps as per rationalized syllabus.

Digestive System

The semi-liquid food formed in stomach is called:

Pick B: Chyme. Thinking about Digestive System in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: this is mainly a definition check, and Chyme is the standard term or meaning used in Digestive System. Hence Chyme is correct. Treat this as a building block for the rest of Digestive System; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Chyme.

Digestive System

Bacteria in colon synthesize which vitamins?

Vitamin B and K (B) is the right choice. This sits at the heart of Digestive System: the wording points straight to what is happening in the tissue or organ system. A useful study habit is to ask what the structure or process is for: Vitamin B and K is the option that correctly names the structure, process, or principle asked for in Digestive System. That reasoning supports Vitamin B and K. One solid sentence about why this works is enough for recall — you do not need a long essay for every MCQ. When you practise, cover the choices first, write Vitamin B and K from memory, then reveal the letter — that habit builds real recall for Digestive System.
