non-caloric (no-calorie sweetener) :

[A] Aspartame
[B] Saccharin
[C] Sucralose
[D] Cyclamate
Correct Answer: C [Sucralose]
Notes:
Sucralose is an artificial sweetener. The majority of ingested sucralose is not broken down by the body
and therefore it is non-caloric. Sucralose is approximately 600 times as sweet as sucrose (table sugar),
twice as sweet as saccharin, and 3 times as sweet as aspartame. It is stable under heat and over a broad
range of pH conditions. Therefore, it can be used in baking or in products that require a longer shelf life.
The commercial success of sucralose-based products stems from its favorable comparison to other low-
calorie sweeteners in terms of taste, stability, and safety.It is used because it is a no-calorie sweetener,
and does not promote dental cavities, is safe for consumption by diabetics, and does not affect insulin
levels.

[A] It reacts with moisture and releases Ethylene
[B] It reacts with moisture and releases Acetaldehyde, which in turn releases ethylene
[C] It reacts with starch and releases Acetylene
[D] It reacts with moisture and releases Ethyne
Correct Answer: A [It reacts with moisture and releases Ethylene]
Notes:
or reasons of safe transportation of fruits, mangoes, bananas etc are picked before they ripen fully.
Slightly green harvested mangoes are subjected to small containers of calcium carbide (CaC2) with a
plastic covering. CaC2 reacts with the moisture in the air to release acetylene (or ethyne) gas as follows:
CaC2 + 2 H2O → C2H2 + Ca(OH)2
This option may give you slightest confusion if you don’t know the difference between Ethylene and
Ethyne (Acetylene). Both are chemical substances produced by fruits to accelerate the normal process of
fruit maturation — is a ripening hormone. Ethylene is C2H4 and has a carbon-carbon double bond.
Acetylene is C2H2 and has a carbon-carbon triple bind. Acetylene contains more energy and burns
hotter than ethylene. Ethylene is a gaseous compound , Acetylene is the chemical compound , which is
the simplest alkyne and is also a hydrocarbon while Ethylene is the simplest alkene and classified as an

unsaturated hydrocarbon. I hope you will never forget it now.

[A] Fruit
[B] Cotyledons
[C] Endosperm
[D] Embryo
Correct Answer: C [Endosperm]
Notes:
Most of the essential micronutrients are almost exclusively stored in the husk, aleurone and embryo of
rice, which are removed during the polishing process. Polishing of rice is required as the oil-rich
aleurone layer turns the seed rancid upon storage and therefore making rice unsuitable for
consumption. Consequently, the rice endosperm that comprises the edible part of rice for humans lacks
or contains only small amount of key micronutrients (e.g., iron, zinc, protein, provitamin A, and other
vitamins) that are essential for a healthy diet. Considering the facts above and severity of widespread
micronutrient malnutrition, iron biofortification in rice endosperm is a promising strategy to overcome
iron deficiency effectively.

member of the ABO blood group system`s blood (which always contains one or more of A and B and H
antigens), but only from other people who have Bombay phenotype
