PHYSICS

Which of the following statements is correct about the absorption process in a hydrogen atom?

Absorption occurs when an electron jumps to a higher energy level by absorbing a photon matching the energy difference between levels. This follows from NCERT principle where relation explains outcome clearly for students.

Ref: NCERT Physics Textbook for Class XI and XII, Chapter: Atoms, Topic: Absorption in hydrogen atom, electron excitation to higher energy level by photon absorption. The section explains definitions, governing laws, formulas like μ₀ = 4π × 10⁻⁷ T·m/A, units and illustrative examples.

plant Development -ll

Root hairs emerge in:

Root system zonation comprises protective root cap covering meristematic zone with dividing initials, rapid elongation zone where cells undergo extensive vacuolar expansion increasing length dramatically, and maturation zone where differentiation completes and specialized cells emerge. Root hairs, tubular tip-growing extensions of specialized trichoblast epidermal cells, arise exclusively in maturation zone after cessation of elongation ensuring stable anchorage and efficient water and mineral nutrient absorption. Specification depends on positional signaling from underlying cortex, transcriptional cascade involving WER, GL3/EGL3, GL2, RHD6, and RSL4 dictating hair versus non-hair epidermal fate decisions.

Ref: Dolan & Davies, Plant Cell Monogr; Gilbert Plant Development: root hairs emerge exclusively in maturation/differentiation zone.

The organism belongs to Kingdom Fungi. Fungi are absorptive heterotrophs, their walls contain chitin and other polysaccharides, and their reserve food is stored as glycogen and oil droplets.

Digestive System

Movement of digested products into blood or lymph is called:

Pick B: Absorption. Thinking about Digestive System in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: this is mainly a definition check, and Absorption is the standard term or meaning used in Digestive System. Hence Absorption is correct. Treat this as a building block for the rest of Digestive System; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Absorption.

Ref: Animal physiology is Unit 7 of the CSIR NET Life Science Syllabus, covering core body systems. It accounts for roughly 10% of the total marks in Sections B and C.
