A Correct answer
Explanation

Excessive burning of fossil fuels is a major cause of "GLOBAL WARMING".

Explanation :
Carbon dioxide (CO2), which, while not  the most potent greenhouse gas, 

is nevertheless the main driver of the greenhouse effect. When fossil fuels - coal, oil and natural gas - are burnt they release CO2 into the atmosphere. Because of this, the layer of greenhouse gas is getting thicker, which is, in turn, making the Earth warmer. Thus the ongoing unlimited burning of fossil fuels is the cause of climate change and global warming.

B Correct answer
Explanation

The intoxicating substance in tobacco is Nicotine.
Nicotine abuse is unique because the drug’s intoxicating effects are less intense than most other substances. Although it is a stimulant, nicotine doesn’t produce the high levels of energy or euphoria that drugs like cocaine do. Nicotine does, however, stimulate adrenal glands, which causes a rise in blood pressure and respiration.

Car wax is prepared from

  1. Vegetable wax

  2. Animal wax

  3. Mineral wax

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A traditional car wax formula usually consists of a blend of carnauba wax, mixed with other waxes, such as beeswax, natural oils, and will sometimes also include petroleum distillates. Carnauba wax is a hard wax obtained from the leaves of a Brazilian palm tree which produces a glassy shine. Carnauba based waxes must be reapplied frequently in order to maintain shine. Beeswax is a durable wax found in honeycombs and used in car wax formulas to provide a protective barrier. Natural oils, such as linseed oil, are emollients use to provide added shine, luster, and protection, to the painted surface. Petroleum distillates are solvents derived from crude oil that make the wax easier to spread and to clean the paint.

So, the correct answer is option D.
