Question 464

Rickets is a disease caused by the deficiency of

AVitamin- K

BVitamin- D

CVitamin- B1

DVitamin- A

Show answer

B. Vitamin- DExplanation: Rickets is a bone disease caused by the deficiency of Vitamin D in children. Vitamin D is essential for the proper absorption of calcium and phosphorus from the intestine, which are vital for healthy bone formation. Its deficiency leads to weak and soft bones, resulting in deformities such as bowed legs and knock knees. The adult form of this disease is known as osteomalacia. Vitamin D can be obtained from sunlight, fish oil, eggs, and fortified milk.

Question 463

Which of the following diseases is not caused by bacteria?

ACholera

BTyphoid

CTuberculosis

DChickungunya

Show answer

D. ChickungunyaExplanation: Chikungunya is a viral disease caused by the Chikungunya virus, which belongs to the Togaviridae family. It is transmitted to humans through the bite of infected Aedes aegypti and Aedes albopictus mosquitoes. The disease causes sudden fever, joint pain, headache, and rash. In contrast, cholera (caused by Vibrio cholerae), typhoid (by Salmonella typhi), and tuberculosis (by Mycobacterium tuberculosis) are all bacterial diseases.

Question 462

Thyroid gland is located

Anear the heart

Bat the base of the brain

Cbelow the liver

Din the neck region

Show answer

D. in the neck regionExplanation: The thyroid gland is located in the neck region, just below the larynx (voice box) and in front of the trachea (windpipe). It is a butterfly-shaped endocrine gland that secretes the hormones thyroxine (T₄) and triiodothyronine (T₃). These hormones regulate metabolism, growth, and energy production in the body. The thyroid also produces calcitonin, which helps control calcium levels in the blood. Iodine is essential for the synthesis of thyroid hormones.

Question 461

Decibel is the unit used for

Aintensity of light

Bintensity heat

Cintensity of sound

Dfrequency of radio wave

Show answer

C. intensity of soundExplanation: The decibel (dB) is a unit used to measure the intensity or loudness of sound. It expresses sound level on a logarithmic scale relative to a standard reference intensity of 10-12 watt/m², which is the faintest sound the average human ear can hear. Normal conversation is around 60 dB, city traffic about 80–90 dB, and sounds above 120 dB can cause pain or hearing damage. The decibel scale helps compare very large variations in sound intensity conveniently.

Question 460

Light year is a unit of measurement of

Aspeed of light

Bstellar distances

Cspeed of rockets

Dtime

Show answer

B. stellar distancesExplanation: A light year is a unit used to measure stellar or astronomical distances. It is defined as the distance that light travels in one year in a vacuum. Since light moves at a speed of about 3 × 108 m/s, one light year equals approximately 9.46 × 1012 km. It is commonly used to express distances between stars and galaxies because these distances are too large to be measured in kilometers or miles.

Question 459

Malaria is caused by

Aparasitic infection

Bviral infection

Cbacterial infection

Dfungal infection

Show answer

A. parasitic infectionExplanation: Malaria is caused by a parasitic infection of the genus Plasmodium. The disease spreads to humans through the bite of an infected female Anopheles mosquito. When the mosquito bites, it injects Plasmodium sporozoites into the bloodstream, which travel to the liver, multiply, and infect red blood cells. Common species causing malaria include P. vivax, P. falciparum, P. malariae, and P. ovale. Symptoms include fever, chills, sweating, and anemia. It can be prevented by mosquito control and use of antimalarial drugs.

ABangladesh

BIndia

CJapan

DScotland

Show answer

B. IndiaIndia is the second-largest tea-producing country in the world, following China.

Question 455

Full form of "GPS" is

AGeographic Pointing System

BGlobal Positioning System

CGeographic Photo Sensor

DGlobal Polar Synchronization

Show answer

B. Global Positioning SystemExplanation: The full form of GPS is Global Positioning System. It is a satellite-based navigation system that provides accurate information about the location, speed, and time anywhere on Earth. Developed by the U.S. Department of Defense, GPS uses a network of at least 24 satellites orbiting the Earth. It is widely used in navigation, mapping, military operations, aviation, and smartphone tracking applications.
