Question Discussion & Solution

The correct answer is 98.4° F,

Key Points

• The normal temperature of the human body is 37 °C (98.4° F). 
• A temperature above 100.4 °F(38°C) most often means you have a fever.
• Normal body temperature is also called the normal or core body temperature, which is based on Homeostasis.
• ​Homeostasis is a phenomenon in which the body regulates its functions to keep the internal conditions as stable as possible.
• The normal human body temperature border is typically stated as 36.5–37 °C (97.7–98.6 °F).
• Human body temperature depends on gender, age, time of day, exertion level, health status
  • Also in what part of the body the measurement is taken at.
• Body temperature is kept in the normal range by thermoregulation, in which adaptation of temperature is triggered by the central nervous system.

Thus, the Body temperature of a normal human being is 98.4° F.

The correct answer is Cancer.

Concept: 

Infectious diseases:

• Infectious disease are diseases caused by bacteria, fungi, viruses, or parasites.
• Infectious diseases are transmitted by infectious agents.
• Infectious disease is spread by humans, plants, and insects. 
• Agents that spread pathogens or pass them on are known as vectors or disease intermediaries.

Explanation:

• Cancer is not an infectious disease. 
• Cancer cannot be passed from one person to another by breathing the same air, sharing a toothbrush, touching.
• Cancer is a disorder in which cell growth is uncontrolled.
• Changes in genes that control how our cells function, particularly how they grow and divide, cause cancer.
• Accelerating cell division rates or inhibiting normal control can result in gene mutations. 
• Cancer is sometimes caused by the genes we inherit from our parents.
• Cancer's Causes
  • Carcinogens such as tobacco, chemicals, alcohol, and ultraviolet radiation from the sun are among the leading causes of cancer.

Additional Information

• Cholera:
  • Cholera is a severe diarrheal infectious disease caused by Vibrio cholerae bacteria.
  • People who consume cholera-contaminated food or water may become ill.
  • The infection is frequently mild or without symptoms, but it can also be severe and life-threatening.
  • The disease's deadly effects are caused by a toxin produced by bacteria in the small intestine.
• TB (Tuberculosis):
  • Tuberculosis (TB) is an infectious disease caused by a Mycobacterium tuberculosis bacteria.
  • It was transmitted from person to person via microscopic droplets released into the air.
  • Usually bacteria attack the lungs, but tuberculosis bacteria can attack any part of the body, including the brain, kidney, and spine.
• Conjunctivitis: 
  • Conjunctivitis or pink eye is a viral disease that is caused by allergies or bacterial or viral infection.
  • It is the Inflammation or infection of the eyeball's outer membrane and the inner eyelid.
  • Conjunctivitis is highly contagious and is spread through contact with infected people's eye secretions

The correct answer is Camel.

Key Points

• The state animal of Rajasthan is Camel.
• Camel was adopted as the state animal of Rajasthan to control the decreasing number of camels in the state. 
• It was adopted in 2014 by the Rajasthan state government.

Additional Information

• State Bird: Great Indian Bustard.
• State Animal (Wildlife) - Chinkara
• State Flower: Rohida.
• Chinkara is also the official animal of Rajasthan.
• National Park: Sariska National Park, Ranthambore National Park, Desert National Park, and Keoladeo Ghana National Park.
• Geographical indication: Kota Doria, Kathputlis, Blue pottery, Molela, clay work, Sanganeri Hand Block Printing, Phulkari, Bikaneri Bhujia, Bagru hand block print, Thewa artwork, Makrana marble.

The logic followed here is :

Given expression is : 789 ÷ 689 + 13 – 25 × 1489

Replacing the signs as per the given directions and using the BODMAS rule:

789 - 689 ÷ 13 × 25 + 1489

789 - 53 × 25 + 1489

789 - 1325 + 1489

2278 - 1325

953

Hence, the correct answer is "953".

The correct answer is Gold.

Key Points

• Gold is the most malleable metal as it can be hammered to a thickness of 0.0025 mm.
• 1 gram of gold can be beaten into a sheet that spreads across an area of 1 m².
• Malleability, as a physical property of metals, is used to describe a given metal’s reaction to compressive forces.
• A metal with low malleability, like tungsten, will shatter when exposed to compression.
• A metal with high malleability, like lead, will deform when compressed.
