Question 958

Goverment of India had set up BEE, an autonomous Goverment Agency under Ministry of Power. BEE stands for:

ABureau of Energy Efficiency

BBureau of Electrical and Electronics

CBureau of Enhanced Energy

DBureau of Energy Emission

Show answer

A. Bureau of Energy EfficiencyExplanation: The Bureau of Energy Efficiency (BEE) is an autonomous government agency set up by the Government of India under the Ministry of Power in 2002. It was established under the provisions of the Energy Conservation Act, 2001. The primary objective of BEE is to promote policies and programs that increase the efficiency of energy use in various sectors of the economy. BEE also develops energy efficiency standards and labeling programs for appliances and buildings, such as the star-rating system seen on electrical devices.

Question 957

Which of the following will not cause any atmospheric pollution ?

AHydrogen

BSulphur dioxide

CCarbon dioxide

DCarbon monoxide

Show answer

A. HydrogenExplanation: Hydrogen (H₂) is a clean fuel that does not cause atmospheric pollution when burned. It combines with oxygen to produce water vapor (H₂O) as the only by-product, without emitting harmful gases like carbon monoxide (CO), carbon dioxide (CO₂), or sulphur dioxide (SO₂). Because of this, hydrogen is considered an eco-friendly and renewable energy source and is being promoted as the fuel of the future in hydrogen-powered vehicles and fuel cells.

Question 956

Heavy water is :

AIce

BWater at 4 degree Celsius

CDeuterium oxide

DSolution of sugar and water

Show answer

C. Deuterium oxideExplanation: Heavy water is chemically known as Deuterium oxide (D₂O). It is similar to ordinary water (H₂O), but the hydrogen atoms are replaced by deuterium — a heavier isotope of hydrogen containing one proton and one neutron. Heavy water is not suitable for drinking but is used as a moderator and coolant in nuclear reactors because it slows down neutrons, allowing a controlled nuclear fission reaction. It is also used in scientific research and isotope studies.

Question 955

Which of the following diseases is caused by virus ?

ACholera

BTyphoid

CTuberculosis

DSmall Pox

Show answer

D. Small PoxExplanation: Smallpox is a highly contagious and deadly disease caused by the Variola virus. It is characterized by high fever, fatigue, and a distinctive pustular rash on the skin. Smallpox was one of the most devastating diseases in human history, but thanks to the worldwide vaccination campaign led by the World Health Organization (WHO), it was officially eradicated in 1980. The vaccine for smallpox was first developed by Edward Jenner in 1796.

Question 954

Which of the following elements is essential for the transmission of nerve impulses in nerve fibers of human body ?

ACalcium

BIron

CSodium

DZinc

Show answer

C. SodiumExplanation: Sodium (Na⁺) plays a crucial role in the transmission of nerve impulses in the human body. Nerve cells (neurons) transmit signals through an electrochemical process known as the nerve impulse or action potential. During this process, the movement of sodium (Na⁺) and potassium (K⁺) ions across the nerve cell membrane generates an electrical charge. The rapid influx of sodium ions causes depolarization, which allows the nerve impulse to travel along the neuron, ensuring proper communication between the brain, spinal cord, and body.

Question 953

All enzymes are actually

AProtein

BCarbohydrates

CFatty acids

DSteroids

Show answer

A. ProteinExplanation: All enzymes are proteins (except a few RNA-based enzymes called ribozymes). Enzymes act as biological catalysts that speed up chemical reactions in living organisms without being consumed in the process. They work by lowering the activation energy of reactions, ensuring that metabolic processes occur efficiently at normal body temperatures. Each enzyme is specific to a particular substrate, forming an enzyme-substrate complex to carry out its function effectively.

Question 952

The largest gland of human body is :

AThyroid

BKidney

CPancreas

DLiver

Show answer

D. LiverExplanation: The liver is the largest gland in the human body. It is located in the upper right part of the abdomen, just below the diaphragm. The liver performs multiple vital functions, including the secretion of bile (which helps in digestion of fats), detoxification of harmful substances, storage of glycogen (energy reserve), and the synthesis of proteins and cholesterol. It also plays a crucial role in regulating blood sugar levels and metabolism. The average adult human liver weighs about 1.2 to 1.5 kilograms.

Question 951

Growth hormone is produced by :

ABones

BPituitary gland

CThyroid gland

DAdrenal gland

Show answer

B. Pituitary glandExplanation: The Growth Hormone (GH), also known as Somatotropin, is secreted by the anterior lobe of the pituitary gland, which is located at the base of the brain. This hormone stimulates growth, cell reproduction, and regeneration in humans and other animals. It plays a vital role in increasing height during childhood and adolescence, regulating metabolism, and maintaining muscle and bone mass. A deficiency of GH causes dwarfism in children, while excess secretion leads to gigantism or acromegaly.

Question 950

Bronchitis is a disease of :

ABlood

BLiver

CIntenstine

DRespiratory track

Show answer

D. Respiratory trackExplanation: Bronchitis is an inflammation of the bronchial tubes, which are the air passages of the respiratory tract that carry air to and from the lungs. The condition causes coughing, mucus production, chest discomfort, and difficulty in breathing. It can be caused by viral or bacterial infections, long-term exposure to smoke, dust, or air pollutants. Chronic bronchitis is a serious form often associated with smoking and is part of a group of lung diseases known as COPD (Chronic Obstructive Pulmonary Disease).

Question 949

Which of the following adds/add carbon dioxide to the carbon cycle on the planet earth ? 1. Volcanic action 2. Respiration 3. Photosynthesis 4. Decay of organic matter (Select correct answer)

A1, 2 and 4 only

B1 and 3 only

C2 only

D1, 2 and 3 only

Show answer

A. 1, 2 and 4 onlyExplanation: The processes that add carbon dioxide (CO₂) to the carbon cycle on Earth are: 1. Volcanic action: Volcanic eruptions release large amounts of CO₂ and other gases from the Earth’s interior into the atmosphere. 2. Respiration: All living organisms release CO₂ as a by-product of breaking down glucose during cellular respiration. 4. Decay of organic matter: Decomposition of dead plants and animals by microbes produces CO₂ and methane (CH₄). Photosynthesis (option 3), on the other hand, removes CO₂ from the atmosphere as plants use it to produce glucose and release oxygen.
