I keep getting “Absorption” questions wrong in Digestion & Absorption. What's the trap?
thinking most absorption happens in the stomach.
I keep getting “Oxygen transport” questions wrong in Breathing & Exchange of Gases. What's the trap?
thinking oxygen mostly dissolves in the plasma.
I keep getting “Heart chambers” questions wrong in Body Fluids & Circulation. What's the trap?
mixing up which side carries oxygenated blood.
I keep getting “Urine formation” questions wrong in Excretory Products & Elimination. What's the trap?
thinking all the filtered fluid leaves as urine.
I keep getting “Nerve impulse” questions wrong in Neural Control & Coordination. What's the trap?
thinking the impulse jumps the synapse as electricity.
I keep getting “Insulin and glucagon” questions wrong in Chemical Coordination (Endocrine System). What's the trap?
swapping their roles.
I keep getting “Monohybrid ratio” questions wrong in Principles of Inheritance & Variation. What's the trap?
confusing the 3:1 phenotype ratio with the 1:2:1 genotype ratio.
I keep getting “Semi-conservative replication” questions wrong in Molecular Basis of Inheritance. What's the trap?
thinking both strands of the daughter DNA are brand new.
I keep getting “Variation and adaptation” questions wrong in Evolution. What's the trap?
thinking organisms change themselves on purpose to adapt.
I keep getting “Active vs passive immunity” questions wrong in Human Health & Disease. What's the trap?
calling a vaccine passive immunity.
I keep getting “Menstrual cycle” questions wrong in Human Reproduction & Reproductive Health. What's the trap?
thinking ovulation happens at the start of the cycle.
I keep getting “Restriction enzymes” questions wrong in Biotechnology & its Applications. What's the trap?
thinking restriction enzymes cut DNA at random points.
I keep getting “Ten percent law” questions wrong in Ecosystem & Ecology. What's the trap?
thinking most energy is transferred up the food chain.
What does “Mitochondria” actually mean in Cell: The Unit of Life, and why does it matter for NEET?
the powerhouse of the cell, where aerobic respiration makes most of the ATP; it has its own DNA.
What does “Proteins” actually mean in Biomolecules, and why does it matter for NEET?
polymers of amino acids that build tissues, act as enzymes, and transport molecules.
What does “Meiosis” actually mean in Cell Cycle & Cell Division, and why does it matter for NEET?
reductional division producing four genetically different haploid gametes.
What does “Chlorophyll” actually mean in Photosynthesis in Higher Plants, and why does it matter for NEET?
the green pigment that absorbs mainly red and blue light and reflects green.
What does “Fermentation” actually mean in Respiration in Plants, and why does it matter for NEET?
anaerobic breakdown of pyruvate into ethanol or lactic acid, releasing very little ATP.
What does “Bile” actually mean in Digestion & Absorption, and why does it matter for NEET?
a liver secretion (stored in the gall bladder) that emulsifies fats into small droplets.
What does “Carbon dioxide transport” actually mean in Breathing & Exchange of Gases, and why does it matter for NEET?
most CO₂ travels in the blood as bicarbonate ions.
What does “Blood components” actually mean in Body Fluids & Circulation, and why does it matter for NEET?
plasma (fluid), red cells (carry O₂), white cells (defence) and platelets (clotting).
What does “Nitrogenous waste” actually mean in Excretory Products & Elimination, and why does it matter for NEET?
humans mainly excrete urea, so we are ureotelic.
What does “Reflex arc” actually mean in Neural Control & Coordination, and why does it matter for NEET?
a fast, involuntary response routed through the spinal cord without waiting for the brain.
What does “Thyroxine” actually mean in Chemical Coordination (Endocrine System), and why does it matter for NEET?
the thyroid hormone that controls the body's metabolic rate; it needs iodine.
