NSO - Mock Test - 1

In the given word PROFESSOR, the following pattern is used:
P – 1 = O
R + 1 = S
O – 1 = N
F + 1 = G
E – 1 = D
S + 1 = T
S – 1 = R
O + 1 = P
R – 1 = Q
Similarly, ALLOWED will be coded as follows:
A – 1 = Z
L + 1 = M
L – 1 = K
O + 1 = P
W – 1 = V
E + 1 = F
D – 1 = C

According to the question,
6 × 8 = 48
And 48 – 1 = 47

Similarly, 8 × 8 = 64
And 64 – 1 = 63

The given pattern is made up of two series:
(i) E, F, G, ?
(ii) M, L, K, ?
Now, in the first series, the pattern is to add 1.
So, E + 1 = F
F + 1 = G
G + 1 = H
In the second series, the pattern is to subtract 1.
So, M - 1 = L
L - 1 = K
K - 1 = J
Therefore, the missing terms are H and J.

According to the question,
ACE : IKM
The pattern followed is as follows:
A + 8 = I
C + 8 = K
E + 8 = M
Now, out of the given options, the same rule is applied for option 2 as follows:
R + 8 = Z
T + 8 = B
V + 8 = D

In this series, each number is repeated, then 13 is subtracted to arrive at the next number.
So, 27 - 13 = 14

A, B and C are siblings.
B is the nephew of D, so it means B is a male.
So, B is the brother of C.

The series is as follows:
1 + 1² = 2
2 + 2² = 6
6 + 3² = 15
15 + 4² = 31
31 + 5² = 56

White colour reflects the most amount of heat and absorbs the least amount of heat.

As the pressure decreases, the air from high pressure area moves toward this low pressure area, hence the speed of wind increases.

Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object.

Holes are made in hanging banners and hoardings in order to tackle the air pressure. The air gets passed through these holes made on the hoardings or banners and thus, reduces the pressure of air on them. Therefore, the hoardings do not get blown away or tear due to air pressure.

Punjab is not prone to cyclone as it is not a coastal state.

A convex lens is used as a magnifying glass. The convex lens bends the parallel rays so that they converge and create a virtual image on our eyes retinas. That virtual image on our retinas appears larger than the real object due to principles of geometry.

All the given options are the best ways to help the neighbours in case of cyclone.

Boiling water is an example of a physical change and not a chemical change because water vapour still has the same molecular structure as liquid water (H2O). Since only the state of the substance has changed and not its chemical nature, it is a physical change.

However, electrolysis of water is a chemical change as the following reaction takes place:
2H2O → 2H2 + O2
Burning of wood and rotting of garbage are also chemical changes as the chemical composition of the substance changes.

Uttar pradesh , Punjab and Haryana lies in north India , While Goa is a coastal state hence it experiences the the see breeze.

Camels have thick fur. Camel excrete very small amount of urine and dry dung which help it to conserve water. There's no evidence, though, that camels can store water for long periods of time anywhere in their bodies. Camels store fat in their humps, not water. They can very efficiently conserve water but not store it. Rather than directly storing water, camels are built for adapting to the scarcity of water.

Rainforest is found generally near the equator. Places near the equator receive more sunshine and, therefore, more rainfall. This makes the place hot and humid. Temperatures vary from 15^oC to 40^oC generally near the equator. Rain forests are also present in some tropical areas.Tropical rainforests are warm and moist; while temperate rainforests are cool. To be a tropical rainforest, forested areas must lie between the Tropic of Cancer and the Tropic of Capricorn. One third of the world's tropical rainforests are in Brazil.

When winds flow from land to ocean, they are called land breeze. During night, the land cools down faster than the ocean surface. The warmer air from the ocean surface rises up and creates an area of low pressure near the surface. This is filled in by cooler air from the land. This gives rise to the land breeze.

Cockroaches and other insects breathe through spiracles and tracheae. There is a network of hollow tubes running through the body of an insect. These hollow tubes are called trachea. Each trachea opens on the body surface in the form of very small pore. These pores are called spiracles.

Rainforest is found generally near the equator. Places near the equator receive more sunshine and, therefore, more rainfall. This makes the place hot and humid. Temperatures vary from 15^oC to 40^oC generally near the equator. Rainforests are also present in some tropical areas. Tropical rainforests are warm and moist.

During intense exercise, there may not be enough oxygen available to complete the process, so a substance called lactate is made. Our body can convert this lactate to energy without using oxygen.

Earthworms breathe through their skin. The skin of an earthworm always remains moist, which helps in breathing.

The breathing is controlled by the movement of diaphragm. Diaphragm is a membrane which is between the chest and abdomen. The movement of diaphragm is controlled by a group of muscles, called intercostal muscles.
When the diaphragm moves down, the rib cage expands. This leads to the expansion inside the lungs. As a result, the air moves into the lungs. This process is called inspiration or inhalation.

Acid rain is caused due to the presence oxides of sulphur and nitrogen in the air which dissolve in the rain water to form acids which react with the marble of the Taj Mahal. This is causing the yellowing of the Taj.

Soil erosion is a naturally occurring process that affects all land forms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water and wind or through forces associated with farming activities such as tillage. Less use of fertilisers, planting grass and shrubs, and step farming all are the ways of preventing the soil erosion.

Water conservation includes all the policies, strategies and activities made to sustainably manage the natural resource fresh water, to protect the water environment, and to meet the current and future human demand. Generation of hydro electricity is a measure of making electricity by running water, it has nothing to do with water conservation.

Optics is the study of light. Optics, a segment of physics, evaluates and analyses the properties and behaviours of light.

Crushing of a can only changes the shape of the object and is a physical change.
Since no new substance is produced, it cannot be a chemical change.

Platelets are responsible for clotting or coagulation of blood. In case of an injury, the blood clots after some time. This prevents excess loss of blood. Clotting of blood is a defence mechanism in the body.

Budding is a method which is used by unicellular plants like yeast for reproduction. Yeast is a fungus and fungi are also known as non-green plants. The yeast cell produces a bud which gets its own nucleus. The bud develops to a certain size and detaches from the mother cell to produce the new yeast.

Spinning is an important process in the processing of wool during which the fibres are straightened, combed and rolled into yarn.
The yarn is then woven or knitted to obtain woollen fabric.

Silk is a natural protein fibre, some forms of which can be woven into textiles.
Silk fibre is composed mainly of fibroin protein which is produced by the larvae (silk worms) to form cocoons.
The other options are plant fibres and are comprised of cellulose.

There are two molars on both sides in both the jaws. They have almost a flat surface with small projections. These teeth are meant for fine grinding of food.
There are total 12 molar teeth including the wisdom teeth in an adult human. Wisdom teeth usually grow between the ages of 18 and 21.

Spoiling of the cooked food is a chemical change.
Food is spoiled when microbes decompose the components by secreting some enzymes.
This is a chemical process.

Step 1: Shearing is the first step in the process of obtaining wool from the sheep. The fleece (hair) of sheep is shaved off along with a thin layer of skin.
Step 2: Scouring - Fleece, after shearing, is washed properly to remove dirt and grease.
Step 3: Sorting - After scouring, fleece is sorted according to texture.
Step 4: Dying - After sorting and picking out of burrs, these are dyed in desired colours.
Step 5: Spinning - The fibres are then straightened, combed and rolled into yarn.
