What does “Semi-conservative replication” actually mean in Molecular Basis of Inheritance, and why does it matter for NEET?
each new DNA molecule keeps one original strand and one newly made strand.
What does “Variation and adaptation” actually mean in Evolution, and why does it matter for NEET?
inherited differences among individuals provide the raw material selection acts on.
What does “Active vs passive immunity” actually mean in Human Health & Disease, and why does it matter for NEET?
active immunity is when the body makes its own antibodies; passive immunity is receiving ready-made ones.
What does “Menstrual cycle” actually mean in Human Reproduction & Reproductive Health, and why does it matter for NEET?
a ~28-day hormonal cycle in which ovulation occurs around day 14, driven by FSH, LH, estrogen and progesterone.
What does “Restriction enzymes” actually mean in Biotechnology & its Applications, and why does it matter for NEET?
molecular scissors that cut DNA only at specific palindromic recognition sequences.
What does “Ten percent law” actually mean in Ecosystem & Ecology, and why does it matter for NEET?
only about 10% of the energy at one trophic level passes to the next.
I keep getting “Prokaryotic cell” questions wrong in Cell: The Unit of Life. What's the trap?
thinking prokaryotes have no DNA at all.
I keep getting “Enzyme specificity” questions wrong in Biomolecules. What's the trap?
assuming one enzyme can catalyse many unrelated reactions.
I keep getting “Mitosis” questions wrong in Cell Cycle & Cell Division. What's the trap?
expecting variation from mitosis.
I keep getting “Calvin cycle (dark reaction)” questions wrong in Photosynthesis in Higher Plants. What's the trap?
thinking the 'dark reaction' happens only at night.
I keep getting “Aerobic respiration” questions wrong in Respiration in Plants. What's the trap?
thinking Krebs cycle occurs in the cytoplasm.
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.
