NVS Lab Attendant Mock Test - 1 - NVS TGT/PGT MCQ

As 'Indolence' and 'Work' are opposite to each other in the same way 'Taciturn' and 'speak' are opposite to each other.

From the final arrangement, we get V sits second to the right of S.
Hence, Option B is correct.
References:
Q sits second to the right of P.
Inferences:
From the above reference, we get two different cases:
In case 1, P sits at the corner or in the middle of the side of the table.

References:
R is not an immediate neighbor of P.
R faces inside.
R sits third to the left of W.
Inferences:
From the above references, we get different cases for R, in case 1(a) in which R faces P and in case 1(b) R faces Q.

References:
T sits third to the left of U.
V sits second to the left of U.
Inferences:
So, from this case 1(b) and case 2 will be eliminated as there is no possible place for V in these cases after placing U and T. Hence, we get our final arrangement in which S sits on the immediate left of P and V sits on the immediate right of R.
Final arrangement:

From Statement 1:

No one has exam after S.

Three people has exam between S and R.

N has exam before R.

M has exam after Thursday.

W has exam before B.

From, this statement, we get:

 So, from this statement, N has exam immediately after B.

From Statement 2:

Two people have exam before R, who has exam immediately after S.

B has exam after R but not on Saturday.

N has exam immediately after H.

From this statement, M has exam immediately after B.

So, either statement 1 or statement 2 alone is sufficient to answer the question.

Hence option C is correct.

From Statement 1:

N is the son of L, who is married to O.

L has only one child.

H is the father-in-law of N.

O is the mother-in-law of Q.

From, this statement, we can arrange the family tree as possible-

So, from this statement, we determine that L is father-in-law of Q.

From Statement 2:

H has only one son and one daughter, one of which is N.

Q is the sister of N, who is the son of M.

M is the mother-in-law of O, who is the mother of L.

From this statement, we can draw the family tree as follow:

So, from this statement, we cannot determine how L is related to Q, because here we don’t know the gender of L.

Hence option A is correct.

The Danish World No.1 Viktor Axelsen clinched victory in the Japan Open final after defeating Jonatan Christie of Indonesia.
In women’s singles, world number two An Se-Young of South Korea beat He Bing Jiao of China to clinch the title. She also replaced replacing Japan’s reigning world champion Akane Yamaguchi to bag the World No. 1 spot.

The walls of the Vaikunda Perumal Temple in Uttaramerur are inscribed with details revealing systems of local governance from the 10th century CE.

The correct answer is the Quasi-Judicial Procedure.

Important Points

• The procedure of Impeachment of the President of India is the Quasi-Judicial Procedure.
• The procedure begins with the introduction of a bill in either house of Parliament.
• The only condition for the initiation of the impeachment of the Indian president is the ‘violation of the constitution.
• None of the presidents of India has faced impeachment so far.
• A quasi-judicial body is an organ of Government other than a Court or Legislature, which affects the rights of private parties either through adjudication or rulemaking”.
• It is not mandatory that a Quasi-Judicial Body has to necessarily be an organization resembling a Court of Law.
  • For example, the Election Commission of India is also a Quasi-Judicial Body but does not have its core functions as a Court of Law.
• Some examples of Quasi-Judicial Bodies in India are the Election Commission of India, the National Green Tribunal, and the Central Information Commission (CIC).

Key Points

• Process of Impeachment of the President of India:
  • When a President is to be impeached for violation of the Constitution, the charge shall be preferred by either House of Parliament.
  • For the motion to be valid, it must be signed by at least one-fourth of the total members of the house where it is introduced
  • In the case of the Lok Sabha, this means that the motion must be signed by at least one-fourth of the total Lok Sabha members.
  • A 14-day notice is given to the President of India.
  • Then, Lok Sabha passes the impeachment charges with a two-thirds majority and sends it to Rajya Sabha.
  • Then, the Rajya Sabha investigates the charges.
  • While Rajya Sabha is investigating the charges, the President has the right to sit in the proceedings.
  • Rajya Sabha agrees to the charges and passes it with a two-thirds majority and the President is removed.

Explanation : One word substitute is Omnivorous.

Omnipotent: (of a deity) having unlimited power.
Insolvent: unable to pay debts owed.
Omniscient: knowing everything.
Omnivorous: (of an animal or person) feeding on a variety of food of both plant and animal origin.

As we know that ,
Irascible is hot tempered, or someone who easily gets angry, roguish is playful ., it is more clearly an antonym to hot tempered than friendly or even kind. Both words Irascible and roguish concern the temperament of a person, while others are about his nature.
Hence , roguish is antonym of Irascible

Correct Answer:
c) competing for various resources of crops (plants) causing low availability of nutrients

Explanation:

Weeds primarily affect crop plants by competing with them for essential resources such as nutrients, water, and sunlight. This competition can result in the crop plants receiving insufficient resources for optimal growth and development, ultimately reducing their yield.

• Option a: Although weeds may interfere with the growth of crops, the phrase "killing of plants in field before they grow" is not an accurate or common description of how weeds affect crops.

• Option b: The statement "dominating the plants to grow" is ambiguous and does not clearly describe the competitive nature of weeds.

• Option c: This accurately captures the primary mode of interference—competition for resources—which leads to a lower availability of nutrients and other vital resources for the crop plants.

• Option d: Since options a and b are not correct, this option is not applicable.

Thus, the correct answer is c).

The purpose of the menstrual cycle, which takes around 28 days every month, is to prepare the uterus for the potential implantation of a fertilized egg. When fertilization does not occur, the thickened lining of the uterus is shed through the vagina as part of the menstrual flow. This cyclic process helps maintain the health of the reproductive system and is a key aspect of the female reproductive cycle.

It is the only metal that is liquid at room temperature. It has the lowest melting point and boiling point of any other metal. It has low thermal conductivity, and a quite low electrical conductivity. It is the only metal that doesn’t form diatomic molecules in the gaseous phase.

Hydrochloric acid ionises as follows :
HCl→ H⁺ +Cl^- 
H⁺ ions combine with water molecules to form H₃O⁺. Therefore, the ions present in dilute aqueous solution of hydrochloric acid are H₃O⁺ and Cl^-.

Hydroelectricity power stations use the kinetic energy in moving water. But the water comes from behind a dam built across a river valley. The water high up behind the dam contains potential energy.

A nanometer (nm) is a decimal fraction of the base SI unit of length, the meter, which is defined as the length of the path travelled by light in vacuum during a time interval of 1/299,792,458 of a second.

The noble gases are missing from Newlands' octaves because these elements were not known at that time. 

When we touch any hot object without knowing it is hot, we immediately throughout the object to safe our hand from burning. We have a sensory nerve in our brain to detect the heat. The nerves that are connected to the muscles of the hand are also connected with the sensory nerves. This connection of detecting the signal from the nerves to the muscles for immediate action is called Reflex Arc. 

Instant and automatic responses are possible by Reflex Arc. The connection between input and output nerves are connected by Reflex Arc and meets in a bundle in the spinal chord. All the nerves on their way to brain meet in a bundle in the spinal chord to send the information to the brain.

Density of copper = 9 gm/cm^3
Mass of copper  =  90 g
We know;  Density =  mass / volume
⇒ volume  = mass / density
⇒    90 / 9
⇒ Volume  = 10 cm³

The fine water molecules mainly scatter blue light due to its shorter wavelength.

The correct answer is It is a closed system.
Key Points

• Ecosystem:
  • Ecosystem, a natural resource system, the complex of living organisms, their physical environment, and all their interrelationships in a particular unit of space.
  • An ecosystem is an open system that can be categorized into its abiotic constituents, including minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consisting of all its living members. Hence, statement 3 is incorrect.
  • Linking these constituents together are two major forces: the flow of energy through the ecosystem, and the cycling of nutrients within the ecosystem.
  • The fundamental source of energy in almost all ecosystems is radiant energy from the Sun.
  • The energy of sunlight is used by the ecosystem’s autotrophic, or self-sustaining, organisms. Consisting largely of green vegetation, these organisms are capable of photosynthesis i.e., they can use the energy of sunlight to convert carbon dioxide and water into simple, energy-rich carbohydrates.
  • The autotrophs use the energy stored within the simple carbohydrates to produce the more complex organic compounds, such as proteins, lipids, and starches, that maintain the organisms’ life processes.
  • The autotrophic segment of the ecosystem is commonly referred to as the producer level.

Additional Information

• The organic matter generated by autotrophs directly or indirectly sustains heterotrophic organisms.
• Heterotrophs are the consumers of the ecosystem; they cannot make their own food.
• They use, rearrange, and ultimately decompose the complex organic materials built up by the autotrophs.
• All animals and fungi are heterotrophs, as are most bacteria and many other microorganisms.
• Together, the autotrophs and heterotrophs form various trophic (feeding) levels in the ecosystem: the producer level, composed of those organisms that make their own food; the primary consumer level, composed of those organisms that feed on producers; the secondary consumer level, composed of those organisms that feed on primary consumers; and so on.
• The movement of organic matter and energy from the producer level through various consumer levels makes up a food chain.
• For example, a typical food chain in a grassland might be grass (producer) → mouse (primary consumer) → snake (secondary consumer) → hawk (tertiary consumer).
• Actually, in many cases the food chains of the ecosystem overlap and interconnect, forming what ecologists call a food web.
• The final link in all food chains is made up of decomposers, those heterotrophs that break down dead organisms and organic wastes.
• A food chain in which the primary consumer feeds on living plants is called a grazing pathway; that in which the primary consumer feeds on dead plant matter is known as a detritus pathway.
• Both pathways are important in accounting for the energy budget of the ecosystem.

Surgery to treat cataracts involves removing the clouded lens and replacing it with a synthetic new one. This procedure is safe and very effective.They're researching eye drops that may dissolve cataracts so patients don't have to go to surgery.

The correct answer is Acid rain.

Key Points

• Taj Mahal is getting damaged due to the effects of Acid rain.
• Acid rain is a byproduct of a variety of human activities that emit the oxides of sulphur and nitrogen in the atmosphere.
• Crude-oil refineries situated in nearby Mathura, spew out vast quantities of sulphur dioxide into the atmosphere.
  • It is carried by winds and acid rain to Agra.
  • ​Acid rain-induced marble cancer is the progressive degradation (or eating away) of marble monuments.
  • Tajmahal is made of marble (CaCO3) which reacts with sulphuric acid of the acid rain. It causes pitting, decolourization and lusterless.
• CaCO₃ of Taj Mahal combines with Sulphuric acid to give → CaSO₄ + H₂O+ CO₂.
• To constrain the damage to the Taj Mahal caused by the oxides of sulfur and nitrogen, the government of India announced an action plan in 1995.
• There are two types of acidic deposition- wet and dry.
• Wet deposition refers to any type of precipitation that takes acids from the atmosphere and deposits them on the earth’s surface.
• Dry deposition of harmful particles and gases clings to the ground in the absence of precipitation via dust and smoke.

Metals have 1-3 electrons in their outermost orbit. They are present on the extreme left of the periodic table. They tend to donate electrons and obtain the stable electronic configuration of the nearest noble gas. The valency on metals also ranges from 1-3 .

Due to the atmospheric refraction, we can see the sun 2 minutes before and after actual sunrise and sunset. The rays of light emitted by the sun are refracted towards the ground while travelling through the optically rarer layers of air in the atmosphere; when the Sun is slightly below the horizon. This results in making the sun appear slightly raised above the horizon and hence the sun is visible 2 minutes before and after actual sunrise and sunset.
