See if the Mnemonics that i have wrote for myself works for you!

DONBAS region has been already asked but thing to remember is that it is rich in coal and below it is the sea of AZOV which is connected to BLACK sea via straight of KERCH and which is a chok point under Russian control.

In my understanding the highly probable question from map section is the border of Turkiye also called Turkey. Especially remember that Azerbaijan borders it.

Many map miss this. Once popular maps used to omit/simplify the part of the map where North Korea meets Russia and UPSC asked about it which prompted all the maps in market to be corrected!

HPV Virus does not use reverse transcription and is not a retrovirus. It is from Papollomaviridae family. It has double stranded DNA (dsDNA).

Phthalates and Oligomers are endocrine disruptors and linked to hormonal imbalances. They also bioaccumulates. These are found in soft plastic. Its very job is to make plastic soft and slippery. Thinner the plastic more leachate will be there.
Note - Food, that directly consumed, are main source of these substabces such as pouched milk than that can be peeled or cooked such as fruits and vegetable. Avoid pouched milk, curd and buttermilk if you want!
THALATES are important for exam, rest info are for general purpose!

Micro Plastics (MP) carry adsorbed toxins, crossing gut barriers to blood/brain. In high temperature region such as India and rough handling amplify leachate of mocriplastics and substances like thalates and oligomers.

Energy Pyramid is always uprught.
Number Pyramid could be upright (Grassland) or inverted (Trees).
Buomass Pyramid can also be upright (Usually on land) or inverted (Usually in aquatic system).
Decomposers are depicted outside or in the side of the pyramid.

Animal cell lacks cell wall.
Plant cell have cell wall made up of cellulose.
Fungi have cell wall of Chitin.
Diatoms have cell walls of Silica.

✳️Normal Smog: SO2 + Fog
✳️Photochemcal Smog: Sunlight + NOx + VOC --> Ground Ozone + PAN + Nitric Acid + Aldehydes.

In ants, bees, and wasps, females develop from fertilized eggs (diploid) and males from unfertilized eggs (haploid).
Worker ants and bees are exclusively unfertilised females while in termites workers could be sterile males or females.

Water vapor is actually the single most potent greenhouse gas on Earth, responsible for about 60% of the natural greenhouse effect. Yet, it is not a primary cause of global warming. It is classified strictly as a Climate Feedback.

Chambal River has only viable population.
CITES I
WPA I
IUCN CR

Attention: If an indigenous Indian species is already listed in Schedule I of the Wildlife (Protection) Act (WPA), 1972, and is later added to a CITES Appendix, it does not leave Schedule I to become just a "Schedule IV" species. Thus this turtle is WPA I species and not WPA IV species.

Two problems with Biofuel (in addition to other)
1. NOx emmission Is higher than fossil fuel, generally speaking.
2. Cold flow
Fossil fuel -5°C to -15°C
Biodiesel (B100) 0°C to 15°C
The fuel start to crystalise at this temperature range

I am sure, you already know that biofuel are less energy dense than fossil fuel and you already know that biofuels emmit less GHG gasses and adds to ebergy security to fuel import dependent countries.
