Damped and forced oscillations: does amplitude really go infinite at resonance, and which frequency does the system oscillate at?
I made a colour-coded summary but the resonance part doesn't add up.

Nephron confusion: if the descending limb loses water and the ascending limb loses salt, who exactly concentrates the urine?
Doing excretory products in class 11 and I made a colour-coded flowchart green for reabsorption, red for secretion but now I'm stuck on the loop of Henle and my flowchart doesn't help. What I understood: filtrate goes PC

Krebs cycle products: per turn or per glucose? My diagram and my MCQ answer key disagree
I colour-code everything blue for NADH, orange for FADH2, green for ATP and in my Krebs cycle diagram I wrote per turn: 3 NADH, 1 FADH2, 1 ATP, 2 CO2. But in the summary table for "one glucose molecule" I copied 6 NADH,

NCERT says steel is more elastic than rubber, but rubber stretches so much and returns. What am I missing?
I'm colour-coding the Mechanical Properties of Solids chapter and I hit a statement I can't reconcile: "steel is more elastic than rubber". But rubber stretches a lot and comes back, while steel hardly stretches at all.

Vernier zero error sign confusion + is parallax angle for a star the full shift or half?
Two small things from the measurement section that keep tripping me in my colour-coded notes I have a whole pink page for "zero error" and it still isn't clear . 1. Vernier calipers. Main scale smallest division is 1 mm

Why do oxides go from basic to acidic across a period, and why are CO and NO called neutral oxides?
I colour-coded the oxide trend for period 3 in my notes: blue for basic Na2O, MgO , green for amphoteric Al2O3 , red for acidic SiO2, P4O10, SO3, Cl2O7 . NCERT states the trend but I want to understand the reason, becaus

Where exactly are root hairs vs meristem vs root cap, and why is a monocot root system "fibrous"?
I just finished colour-coding the root chapter in Morphology of Flowering Plants and then looked at my own diagram and I have no idea whether I drew it correctly. What I wrote from NCERT: four regions in the root tip. Ro

Easy 10-minute dinners for a hostel where I only get a kettle?
Next month I'm shifting to a hostel for my class 12 year because my parents think the commute is eating into my study time. I'm excited and nervous in equal parts, and one of my nervous parts is food. The mess serves din

Bark vs periderm, and which part of the wood is heartwood, annual rings confusing me
I colour coded the secondary growth section blue for xylem, pink for phloem, green for cambium and now I realised the colour code is useless because I'm not sure what some of the terms even mean. 1. Periderm = cork cambi

Competitive vs non-competitive inhibition: what happens to Vmax and Km? I keep flipping them
I made a colour-coded table for enzyme inhibition green for competitive, orange for the other one and I still get the Km/Vmax part wrong every single time. What I understood from NCERT: the enzyme has an active site, the

Hydrogen sits in group 1 but behaves like a halogen too, so where does it actually belong? Also which isotope is radioactive?
I've been colour coding the Hydrogen chapter and the very first heading has me stuck. Hydrogen's configuration is 1s^1 so it looks like an alkali metal, it loses one electron to give H^+ , and it's placed in group 1. But
