Dropper, NEET · Coimbatore. I write less than I think. Observer by nature. Off-duty: reading, kolam art, bird watching.
I usually don't post questions, but this chapter has defeated my reading-only method. ECG: P wave, QRS complex, T wave. I know the NCERT lines: the P wave represents the electrical excitation depolarisation of the atria,
I read slowly, so I've gone through "Origin and Evolution of Man" three times, and I still muddle the facts. I'm trying to build one table in chronological order and I'd like to check it. My notes: - Dryopithecus and Ram
I don't post much, but this one has been bothering me for days. The noble gas chapter. We were told noble gases are "inert", and then straight away we're told xenon forms fluorides and oxides. Why xenon and not helium or
Second attempt at NEET. Going through post-fertilisation events again, and slowly, because last time I rushed this part and fell for a few options. NCERT says the primary endosperm nucleus PEN divides first, often before
I read the NCERT equilibrium chapter twice and one word keeps bothering me: "dynamic". The book says at equilibrium the rate of forward reaction equals the rate of reverse reaction. And that concentrations stay constant.
I don't post often, but this one has been bothering me for two days. NCERT says the pressure flow hypothesis explains translocation in the phloem. Sugar sucrose is loaded actively into the sieve tubes at the source like
I do not usually post, but this one has been bothering me for a few days. Dynamics of Circular Motion. A car turns on a flat horizontal road. The book says the force that provides the centripetal force is the static fric
I read Huygens' principle: every point on a wavefront is a source of secondary spherical wavelets, and the new wavefront is the forward envelope of them. NCERT then derives Snell's law for a plane wavefront AB hitting a
I redrew the human brain diagram three times and I can label it, but the functions slip away after a day. What I have: the forebrain is the cerebrum, thalamus and hypothalamus. The midbrain sits between the forebrain's t
Early morning revision, so forgive me if this is basic. NCERT says the radius of a nucleus is R = R 0A^{1/3}, \qquad R 0 = 1.2\text{ fm} and then it says the nuclear density is roughly the same for all nuclei, around 10^
