[A] The level of water will go upo
p
[B] The level of water will go
h
sdown
[C] The level of water will remain unchanged
[D] The level of water will first increase then come to the previous on
Answer: B [The level of water will go down]- There are two dimensions of this experiment.
One is when Ice floats in water and another is as mentioned in the question. When Ice floats in
water, the level of water will remain unchanged when the ice melts away because in this
situation, Ice replaced water which is `equal to its weight`. But when the floating ice is taken
down in the bottom of the bucket and tied over there with a string, and let melt away, the level of
water will come down because now the ice was replacing the water `equal to its volume `and
Ice has a lower density of water. So The answer of this question is -The level of water will go
down.

Answer: C [1 & 3 are correct]- The Resourcesat was launched recently via the PSLV C-16.
The first statement which says that Resourceset-2 will be able to collect data from a wider strip
of the Earth`s surface is correct. The profile page of Resourcesat-2 on ISRO website mentions
that important changes in RESOURCESAT-2 compared to RESOURCESAT-1 are-
Enhancement of LISS-4 multispectral swath from 23 km to 70 km and improved radiometric
accuracy from 7 bits to 10 bits for LISS-3 and LISS-4 and 10 bits to 12 bits for AWIFS. Besides,
suitable changes, including miniaturization in payload electronics, have been made in
RESOURCESAT-2. The Swath width means the strip of the Earth`s surface from which data are
collected by a satellite.
Statement 2 is NOT correct, because Resourcesat-1 was doing the same job and now
Resourcesat-2 extends that.

The three laws of Kepler can be stated as follows:

Law of orbits: All planets move in elliptical orbits with the Sun situated at one of the foci of the
ellipse
Law of areas: The line that joins any planet to the sun sweeps equal areas in equal intervals of
time.
Law of periods: The Square of the time period of revolution of a planet is proportional to the
cube of the semi-major axis of the ellipse traced out by the planet. The law of areas can be
understood as a consequence of conservation of angular momentum which is valid for any
central force

non-polar solvents and is non-resistant to attack by oxidising agents. To improve upon these
physical properties, a process of vulcanisation is carried out. This process consists of heating a
mixture of raw rubber with sulphur and an appropriate additive at a temperature range between
373 K to 415 K. On vulcanisation, sulphur forms cross links at the reactive sites of double
bonds and thus the rubber gets stiffened.
In the manufacture of tyre rubber, 5% of sulphur is used as a crosslinking agent

27. Why do the bacteria develop resistance after slowly being exposed to a particular

Due to mutation in genes s h

Due to Horizontal Gene Transfer
Due to Vertical Gene Transfer
Choose the correct option:
[A] Only 1
[B] Only 1 & 2
[C] Only 2 & 3
[D] 1, 2 & 3
Answer: B [Only 1 & 2]- Antibiotic resistance occurs from random mutations, the first choice
given is correct. The slow exposure to an antibiotic will give more chance for mutations to
occur. Most antibiotics are derived from naturally derived from organisms, penicillin was
derived from the mould Penicillium, other antibiotics have also been extracted from bacteria,
and these bacteria will be resistant to that antibiotic. The Horizontal Gene Transfer is
considered to be the main culprit of the antibiotic resistance. Horizontal gene transfer (HGT),
also lateral gene transfer (LGT), is any process in which an organism incorporates genetic
material from another organism without being the offspring of that organism. By contrast,
vertical transfer occurs when an organism receives genetic material from its ancestor, e.g., its
parent or a species from which it has evolved. Horizontal gene transfer is also the primary
reason for bacterial antibiotic resistance and this often involves plasmids. Genes that are
responsible for antibiotic resistance in one species of bacteria can be transferred to another

118 | P a g e https://sscstudy.com/ shop.ssbcrack.com

shop.ssbcrack.com
MCQs GENERAL SCIENCE MCQs
https://sscstudy.com/

species of bacteria through various mechanisms. The resistance spreads across bacterial
species usually by transfer of genetic material via a vector, this vector tends to be a circular
piece of genetic material known as a plasmid. Operons within the plasmid code for several
genes, a combination of proteins including an enzyme which is able to deactivate antibiotics,
for example beta-lactamase is an enzyme which cleaves beta-lactam rings, deactivating
penicillin and its derivatives (although certain derivatives like methicillin are resistant to beta
lactamases). Sequences within plasmids that can transfer to the cell‘s own genetic material is
known as a transposon.
The third choice ―vertical gene transfer‘ is not correct. Vertical Gene Transfer means
reproduction.

h
s
[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
Answer: A [It reacts with moisture and releases Ethylene]- 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.

30. Which among the following is the edible part in Rice?

[A] Fruit
[B] Cotyledons
[C] Endosperm
[D] Embryo
Answer: C [Endosperm]- 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.
