NEET/JEE/CET Study Group:
▪️Chemistry Important One Liner ▪️
🔹 The industrial production of aluminum from bauxite is by industrial process - electrical decomposition
🔹 Hydrogen is made up of acids, hydrogen and elements - chlorine.
🔹 The commercial utility of ethylene and styrene is due to their potential – polymerization
🔹 The compound that does not form a clean solution with water is benzoic acid.
🔹 Pure alcohol from Sura can be obtained from this process- Distillation
🔹 The highest amount of substance found in ocean water is- ordinary salt
🔹 The gas produced by the fermentation of a sugar solution is- carbon dioxide.
🔹 The pH of an aqueous solution of acetic acid is 2 What will be added to it will increase its pH value- Aqueous ammonia
🔹 Natural substance, which is made up of only one element and from which energy can be obtained – coal
🔹 Water is often not used to extinguish petrol fires because- water and petrol are inseparable. Petrol forms a layer on the surface of water
🔹 Industrial is a group of substances made by electrical decomposition - caustic soda, chlorine, aluminum
🔹 The gas that pollutes the environment is- sulfur dioxide.
🔹 The most important compounds for plant growth are made of- Nitrogen
🔹 How the compound made by heating caustic soda solution with flaxseed oil is used- soap
🔹 Sulfur dioxide and oxygen are two gases used in the industrial production of sulfuric acid
🔹 Steel contains- 0.1–2 percent carbon
🔹 The component of air used in the respiratory process is- oxygen.
🔹 The main role of salts in food is- to make a small amount of hydrochloric acid which helps in digestion of food.
🔹 The most commonly used metal by humans is iron.
🔹 The main component of cow dung gas is – Methane
🔹 The best fertilizer for plants is- compost
🔹 The pH of aqueous solution of hydrochloric acid can be approximately – 2
🔹 The highest element found in rocks and minerals is- silicon.
🔹 The gas used to extinguish the fire is carbon dioxide.
🔹 The aqueous solution of which gas has a strong acidic property - sulfur dioxide
🔴MENSTRUAL CYCLE 🔴
♣︎ It occurs in monkeys, apes and human beings.
♣︎ Cycle consists of 3 phases-menstrual, proliferative and secretory phase.
♣︎Blood flows in the last few days of the cycle. The broken endometrium is passed out during
menstruation.
♣︎Female does not permit copulation during menstrual phase of the cycle.
🔵OESTROUS CYCLE 🔵
♣︎It occurs in non primates like cow, sheep, rat, deer, dog, tiger etc.
♣︎ It consists of a short period of oestrous or heat. it is 12-24 hours in cow followed by anoestrous or passive period.
♣︎Blood does not flow in this cycle. The broken endometrium is reabsorbed.
♣︎ Female permits copulation only during oestrous period.
♣︎Both in plants and animals, hormones are responsible for the transition between different
phases of life cycle.
★Interaction between hormones and environmental factors regulate the
reproductive processes.
[C]🟠 SENESCENCE PHASE 🟠 -
●It is the end of reproductive phase.
