Apples are generally wrapped in waxed paper to

  1. Prevent sunlight from changing its colour

  2. Prevent aerobic respiration by checking the entry of oxygen

  3. Prevent ethylene formation that hastens ripening

  4. Make the apples look costly
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ethylene is a plant hormone. It is also called as ripening hormone as it is responsible for ripening of fruits. Fruit ripening is accompanied by increase rate of respiration. Due to increased respiration, complex carbohydrates are broken down into simpler sugars and cell wall becomes soft. Hence, apples are generally wrapped in waxed paper to slow down the ripening process. Wrapped apples have low respiration rate and prevent ethylene formation. 

Thus, the correct answer is option C.

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.

Apples coated with carbomethylchitosan remains fresh for

  1. $1\ month$
  2. $6\ months$
  3. $1\ year$
  4. $1\ year$ and $6\ months$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Carbonmethylchitosan is the wax-like structure present on the apples like a coating structure. This wax coating is very important in apples because this coating maintains the freshness of apple for a long time is near about 6 to 8 months. This type of chitosan is made by treating the chitin shells and shrimps of other crustaceans with an alkaline substance like sodium hydroxide.
So, the correct option is '6 months'.

Pollen grains can be stored in a viable condition for many years in which of the following conditions?

  1. Anaerobic conditions in 0$^o$ C
  2. Liquid nitrogen (-196$^o$ C)
  3. Liquid nitrogen (0$^o$ C)
  4. Liquid hydrogen (196$^o$ C)
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Pollen grains are stored for many years in the liquid nitrogen, having the temperature of -196 degrees of Celsius. This method of saving is called cryopreservation. The low temperature allows storing for a longer period as it reduces the growth rate of cells. The cryoprotective agents delay the aging of the plants and protect the plants from the damages due to cold.
So, the correct answer is 'Liquid nitrogen (-196$^o$ C)'.
