NEET doubts
500 doubts found
What does “Mendel's laws” actually mean in Principles of Inheritance & Variation, and why does it matter for NEET?
the laws of dominance, segregation, and independent assortment govern how traits pass to offspring.
What does “DNA structure” actually mean in Molecular Basis of Inheritance, and why does it matter for NEET?
a double helix held by complementary base pairing: adenine with thymine, guanine with cytosine.
What does “Natural selection” actually mean in Evolution, and why does it matter for NEET?
individuals best adapted to their environment survive and reproduce more, so their traits spread.
What does “Innate vs acquired immunity” actually mean in Human Health & Disease, and why does it matter for NEET?
innate immunity is the non-specific defence we're born with; acquired immunity is specific and develops after exposure.
What does “Gametogenesis” actually mean in Human Reproduction & Reproductive Health, and why does it matter for NEET?
the formation of gametes — spermatogenesis makes four sperm per cell, oogenesis makes one ovum plus polar bodies.
What does “Recombinant DNA technology” actually mean in Biotechnology & its Applications, and why does it matter for NEET?
inserting a desired gene into a vector and then a host cell to mass-produce a useful product.
What does “Energy flow” actually mean in Ecosystem & Ecology, and why does it matter for NEET?
energy moves one-way through an ecosystem — from the sun to producers to consumers — and is lost as heat at each step.
I keep getting “Cell theory” questions wrong in Cell: The Unit of Life. What's the trap?
forgetting Virchow's addition that cells come only from other cells.
I keep getting “Enzymes” questions wrong in Biomolecules. What's the trap?
thinking enzymes are used up in the reaction.
I keep getting “Phases of the cell cycle” questions wrong in Cell Cycle & Cell Division. What's the trap?
thinking DNA is copied during mitosis.
I keep getting “Light reactions” questions wrong in Photosynthesis in Higher Plants. What's the trap?
thinking the released oxygen comes from carbon dioxide.
I keep getting “Glycolysis” questions wrong in Respiration in Plants. What's the trap?
thinking glycolysis needs oxygen.
I keep getting “Digestive enzymes” questions wrong in Digestion & Absorption. What's the trap?
thinking pepsin works in the mouth.
I keep getting “Gas exchange” questions wrong in Breathing & Exchange of Gases. What's the trap?
thinking gases are actively pumped across the alveoli.
I keep getting “Double circulation” questions wrong in Body Fluids & Circulation. What's the trap?
thinking humans have single circulation like fish.
I keep getting “Nephron” questions wrong in Excretory Products & Elimination. What's the trap?
thinking the whole kidney filters as one unit.
I keep getting “Neuron” questions wrong in Neural Control & Coordination. What's the trap?
thinking the axon receives signals.
I keep getting “Hormones” questions wrong in Chemical Coordination (Endocrine System). What's the trap?
confusing endocrine glands with exocrine glands that use ducts.
I keep getting “Mendel's laws” questions wrong in Principles of Inheritance & Variation. What's the trap?
thinking both alleles blend rather than segregate.
I keep getting “DNA structure” questions wrong in Molecular Basis of Inheritance. What's the trap?
pairing adenine with guanine or cytosine.
I keep getting “Natural selection” questions wrong in Evolution. What's the trap?
reading it as 'survival of the strongest'.
I keep getting “Innate vs acquired immunity” questions wrong in Human Health & Disease. What's the trap?
thinking all immunity is present from birth.
I keep getting “Gametogenesis” questions wrong in Human Reproduction & Reproductive Health. What's the trap?
thinking oogenesis produces four functional eggs like spermatogenesis makes four sperm.
I keep getting “Recombinant DNA technology” questions wrong in Biotechnology & its Applications. What's the trap?
thinking any gene can be expressed without a proper vector and host.
