CO binds haemoglobin (biology slogan, get medical help, not a note-book treatment). CO2 greenhouse. Complete vs incomplete burn: enough air vs not. Blue vs…
Collaborative Tools are software applications designed to facilitate teamwork and communication among individuals who may be working remotely or across…
Acid or alkali, heat. Products: carboxylic piece + nitrogen piece. Protein peptide bonds are amides (biology link). Nylon hydrolyse named as a slogan. Proteins…
For decay y=y0e(-kt); half-life satisfies e(-kT)=12.
Cell Division: Cell division is the process by which a parent cell divides to produce two or more daughter cells. In simple words: Cell division is how…
Cell specialization is the process by which cells develop specific structures and functions to perform particular roles in a multicellular organism. Through…
Mole A mole is an amount of a substance that contains 6.022 × 10²³ particles of that substance. Simple explanation: A mole is just a counting…
Translation: mRNA -> polypeptide at a ribosome. tRNA carries an amino acid; anticodon pairs with codon. A site, P site named. Start: Met-tRNA at AUG. Peptide…
Six Electron Pairs (AX₆): A molecule in which the central atom is surrounded by six bonding pairs of electrons and no lone pairs.
Typical tasks: classify 1/2/3; oxidation products + orange/green; distil vs reflux; iodoform; ester name; dehydration to alkene; carbonate vs carboxylic.…
