I am making a super neat comparison table colours, arrows, stickers, all that! for sperm and ovum, but I got stuck on two rows and I hate leaving blanks! Sperm: head haploid nucleus + acrosome , neck, middle piece mitoch
Boards + NEET so I need this clean. NCERT gives e = NBA\omega\sin\omega t for a coil of N turns, area A, rotating at angular speed ω in a field B. I did a numerical: coil 50 turns, area 0.02 m², B = 0.4 T, rotating at 30
Boards are around the corner and I am still losing marks on amine classification, which is honestly embarrassing for a "toppers' list" student 🙃 Today's confusion: CH 3 3C-NH 2 . The carbon attached to N has three other
I have been reading the transgenic animals part of the biotechnology applications chapter for two days and somehow every use sounds like the same thing to me, "they put a gene in a mouse and study it". NCERT lists a few
Naming haloalkanes drove me slightly mad today and I need a clean rule set. Here is where I keep losing marks. 1. Numbering: when the chain has a halogen and a methyl, which one decides the direction of numbering? For CH
I was reading the opening part of Microbes in Human Welfare slowly this morning, because I realised I have been skipping the "easy" intro parts and just memorising the lists. The text says microbes are present everywhere
I study from NCERT and a few free videos, so I want to be sure of the basic logic. Megasporogenesis is giving me trouble. What I know: ovule has nucellus, integuments, micropyle, funicle, chalaza. One cell in the nucellu
Okay drama alert 🎭 this chapter has betrayed me. Capacitors, combinations and energy. Setup from a question I did: a 2\ \mu\text{F} capacitor is charged to 100 V and then connected positive plate to positive plate to an
I am revising Human Reproduction slowly, one section a day, because I get overwhelmed when I read the whole chapter in one go. Today was the male reproductive system, and my diagram has so many labels that I started to f
I have been staring at this one for almost an hour and I would like to understand it properly rather than memorise a formula. The problem: a 2 M aqueous solution of glucose M = 180 g/mol has a density of 1.2 g/mL. Find i
I'm making my lanthanoid vs actinoid comparison table obviously with colours!! and I got stuck on the oxidation state row. NCERT says lanthanoids mostly show +3, with +2 and +4 only in a few cases, while actinoids show a
ok so I'm stuck on gene mapping in the linkage part of Principles of Inheritance. NCERT says Sturtevant used the frequency of recombination between gene pairs on the same chromosome as a measure of the distance between t
