NEET doubts
500 doubts found
What does “Incomplete dominance” actually mean in Principles of Inheritance & Variation, and why does it matter for NEET?
heterozygotes show a blended, intermediate phenotype (red × white → pink).
What does “Transcription” actually mean in Molecular Basis of Inheritance, and why does it matter for NEET?
copying a gene's DNA into messenger RNA in the nucleus.
What does “Hardy–Weinberg principle” actually mean in Evolution, and why does it matter for NEET?
allele frequencies in a large, undisturbed population stay constant — no evolution.
What does “Antibodies” actually mean in Human Health & Disease, and why does it matter for NEET?
protein molecules made by B-lymphocytes that bind and neutralise specific antigens.
What does “Fertilisation” actually mean in Human Reproduction & Reproductive Health, and why does it matter for NEET?
the fusion of sperm and ovum, which happens in the ampulla of the fallopian tube, not the uterus.
What does “PCR (polymerase chain reaction)” actually mean in Biotechnology & its Applications, and why does it matter for NEET?
a technique that makes millions of copies of a DNA segment using primers and heat-stable Taq polymerase.
What does “Trophic levels” actually mean in Ecosystem & Ecology, and why does it matter for NEET?
the feeding positions in a food chain: producers, primary consumers, secondary consumers, and decomposers.
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).
