What does “Cloning vector” actually mean in Biotechnology - Principles and Processes, and why does it matter for NEET?
a carrier, usually a bacterial plasmid, that ferries recombinant DNA into a host cell.
What does “Active vs passive immunity” actually mean in Human Health and Disease, and why does it matter for NEET?
active immunity is made by your own body after infection or a vaccine (lasting); passive immunity is ready-made antibodies given from outside (quick but short-lived).
I keep getting “Mitochondria” questions wrong in Cell: The Unit of Life. What's the trap?
assuming all cellular energy is made in mitochondria (glycolysis is in the cytoplasm).
I keep getting “Proteins” questions wrong in Biomolecules. What's the trap?
thinking every protein is an enzyme.
I keep getting “Meiosis” questions wrong in Cell Cycle & Cell Division. What's the trap?
thinking meiosis gives identical cells like mitosis.
I keep getting “Chlorophyll” questions wrong in Photosynthesis in Higher Plants. What's the trap?
thinking plants absorb green light for photosynthesis.
I keep getting “Fermentation” questions wrong in Respiration in Plants. What's the trap?
thinking fermentation gives a lot of energy.
I keep getting “Bile” questions wrong in Digestion & Absorption. What's the trap?
calling bile a digestive enzyme.
I keep getting “Carbon dioxide transport” questions wrong in Breathing & Exchange of Gases. What's the trap?
thinking CO₂ is carried mainly by haemoglobin like oxygen.
I keep getting “Blood components” questions wrong in Body Fluids & Circulation. What's the trap?
thinking white cells carry oxygen.
I keep getting “Nitrogenous waste” questions wrong in Excretory Products & Elimination. What's the trap?
thinking humans excrete ammonia directly.
I keep getting “Reflex arc” questions wrong in Neural Control & Coordination. What's the trap?
thinking every response goes through the brain first.
I keep getting “Thyroxine” questions wrong in Chemical Coordination (Endocrine System). What's the trap?
thinking thyroid problems don't relate to diet.
I keep getting “Incomplete dominance” questions wrong in Principles of Inheritance & Variation. What's the trap?
confusing incomplete dominance with codominance.
I keep getting “Transcription” questions wrong in Molecular Basis of Inheritance. What's the trap?
confusing transcription (DNA→RNA) with translation (RNA→protein).
I keep getting “Hardy–Weinberg principle” questions wrong in Evolution. What's the trap?
thinking allele frequencies always drift over time.
I keep getting “Antibodies” questions wrong in Human Health & Disease. What's the trap?
thinking antibodies and antigens are the same thing.
I keep getting “Fertilisation” questions wrong in Human Reproduction & Reproductive Health. What's the trap?
thinking fertilisation occurs in the uterus.
I keep getting “PCR (polymerase chain reaction)” questions wrong in Biotechnology & its Applications. What's the trap?
confusing PCR (which amplifies DNA) with gel electrophoresis (which separates it).
I keep getting “Trophic levels” questions wrong in Ecosystem & Ecology. What's the trap?
forgetting decomposers, which recycle nutrients back to producers.
I keep getting “Five-kingdom system” questions wrong in Biological Classification. What's the trap?
thinking classification is based on size or habitat rather than cell type and nutrition.
I keep getting “Modifications of organs” questions wrong in Morphology of Flowering Plants. What's the trap?
identifying a modified organ by where it grows rather than its structure.
I keep getting “Xylem and phloem” questions wrong in Anatomy of Flowering Plants. What's the trap?
thinking both tissues move water.
I keep getting “Transpiration pull” questions wrong in Transport in Plants. What's the trap?
thinking the roots push all the water up by themselves.
