Seven obligate ranks in order, the plant suffixes (-phyta, -aceae...) and which categories are NOT obligate?
Checklist time again, my favourite part. I'm making a one-pager for taxonomic categories in The Living World and I want the "obligate" ones to be crystal clear. What I have: there are seven obligate categories, in order

Priestley, Ingenhousz, Sachs, Engelmann, van Niel: kaun kya prove kiya? Mixing them up
Bhai photosynthesis ke early experiments wala part mere liye pure confusion hai. NCERT ke paragraph mein 5-6 names hain aur sab ne kuch alag prove kiya, mujhse sab mix ho jaata hai. Writing in English for the post so eve

I sketched for 10 minutes a day for 30 days. Here is my very organised list of what happened
Bad drawings, a lot of pencil dust, and the surprising things a boring daily rule taught me.

Zwitterion confusion: what is the charge of an amino acid at different pH, and how are amino acids classified?
I'm doing the amino acids part of Biomolecules with four colours of pens 😅 and my notes on zwitterion are a mess. This is how I wrote it. Structure: amino acids are "substituted methanes" with four groups on the α-carbon

Is it okay to rewatch the same comfort series every exam season?
Hi everyone, careful question, I've been thinking about this for a week and feel a bit silly asking. Every time my unit tests start, I rewatch the same comedy series. The same one, since class 9. This is the fourth time.

Flatworms vs roundworms: digestive system, flame cells and sexes, I keep swapping them in my table
I have been marking these two phyla in my notes in two colours and still swapped a row in a chapter test. It was a silly loss and I'd like to understand what exactly I confused. What I have for Platyhelminthes: dorsovent

Pluto "hasn't cleared its orbit", but Earth shares its orbit with asteroids too. What does "cleared" mean?
We did the solar system in class today and sir mentioned the 2006 rules for what counts as a planet. I wrote them in my notes in three colours of course , but one of them doesn't make sense to me and I don't want to just

Thermodynamics: delta U = q + w ya q - w? bhai sign hi samajh nahi aata
Bhai ek problem hai. Chemistry teacher ne bataya ΔU = q + w. Physics wale sir ne bola Q = ΔU + W, matlab ΔU = Q − W. Dono ek hi cheez hai ya mere dimaag ka bug hai? Aur ye bhi nahi samajh aa raha ki gas expand karti hai

Why is the RQ of fats about 0.7? And how is the respiratory pathway "amphibolic"?
Making a checklist of RQ for tomorrow's test and I got stuck on the reason part, not the numbers. NCERT: RQ = volume of CO2 evolved / volume of O2 consumed. Glucose: C 6H {12}O 6 + 6O 2 \rightarrow 6CO 2 + 6H 2O , so RQ

Does friction always do negative work? Also why is work zero when I hold a heavy bag still?
Work, Energy and Power. I made a table of "who does positive / negative / zero work" and several rows don't feel right to me. W = \vec F\cdot\vec d = Fd\cos\theta . I get: - Lifting a book at constant speed by h : work d
