Question Discussion & Solution

The pattern here is as follows:

Hence, RENT is the correct answer. 

Concept:

• Force: Force is a push or pull on an object. A force can cause an object to accelerate, slow down, remain in place, or change shape.

Force exerted = mass x acceleration

F = m × a

Acceleration = (Final velocity(v) - Initial velocity(u))/ time

\(a = \frac{{v - u}}{t}\)

Where F is the force exerted on the body, m is mass of the body, a is the acceleration of the body, v is final velocity, u is initial velocity and t s time.

Calculation:

Given,

Mass of body = 6 kg.

Change in velocity = (18 - 6) = 12 m/s

Time= 3 sec

Acceleration = 12/ 3 = 4m/s² 

Force = mass × acceleration

Force = 6 × 4 = 24 Newton.

Hence the correct option is 24 Newton

The correct answer is Sitamata Wildlife Sanctuary.

• The 'Flying Squirrel' is found in Sitamata Wildlife Sanctuary located in Pratapgarh and Chittaurgarh districts.

Important Points

• It does not actually fly: It glides from one tree to another around sunset in the Arampura forest,
• It's nocturnal and therefore it hides during the daytime in its hollow in a Mahua tree.
• Flying Squirrel: 

Key Points

• Sita Mata Wildlife Sanctuary was declared as a protected forest area by the Government of Rajasthan in 1979.
  • It is a dense forest with about 40% of the total land area of the districts Pratapgarh and Chittorgarh.
  • The confluence of three different formations —
    • Malwa Plateau,
    • Vindhyachal Hills
    • Aravali mountain ranges.

Additional Information

• Mukandara Hills
  • It is a national park in Rajasthan,
  • Established in 2004 and consists of three wildlife sanctuaries:
    • Darrah Wildlife Sanctuary.
    • National Chambal Sanctuary.
    • Jawahar Sagar Wildlife Sanctuary.
• Ranthambore Tiger Reserve
  • ​National Park and Tiger Reserve in Rajasthan
  • It is bounded to the north by the Banas River and to the south by the Chambal River.
  • It is named after the historic Ranthambore Fort, which lies within the park.
• Sariska Tiger Reserve
  • National Park and Tiger Reserve in Alwar district, Rajasthan.
  • Important biodiversity area in the Northern Aravalli leopard and wildlife corridor. 

The correct answer is Liver.

Key Points

• Excessive consumption of alcoholic drinks causes damage to the Liver.
  • Alcohol is readily absorbed from the digestive tract, and up to 98% is metabolised in the liver.
  • Each liver cell contains three pathways for alcohol metabolism.
  • All of these result in the production of a highly toxic metabolite which can contribute to liver cell damage.
  • With regular alcohol use, the regenerative ability of liver cells may be inhibited and lead to sustained liver damage.
  • Long term heavy alcohol use may lead to fat accumulation in the liver, which may progress to alcoholic hepatitis, or liver cirrhosis.
  • Over time, excessive alcohol use can lead to the development of chronic diseases and other serious problems including -
    • High blood pressure, heart disease, stroke, liver disease, and digestive problems. 

Additional Information

• Kidney:
  • Healthy kidneys remove wastes and extra fluid from your blood.
  • But when your kidneys fail, wastes and extra fluid can build up in your blood and make you feel sick. 
  • Kidneys can become damaged from a physical injury or a disease like diabetes, high blood pressure, or other disorders.
  • High blood pressure and diabetes are the two most common causes of kidney failure.
  • Kidney failure does not happen overnight.
• Lungs:
  • Chronic alcohol abuse and heavy drinking can greatly increase the risk of several pulmonary conditions.
    • including lung disease, alcoholic pneumonia, acute lung injury, and acute respiratory distress syndrome.
  • Smokers are more likely than nonsmokers to develop heart disease, stroke, and lung cancer.
    • Smoking can cause lung disease by damaging your airways and the small air sacs (alveoli) found in your lungs.
    • Lung diseases caused by smoking include COPD, which includes emphysema and chronic bronchitis.
• Heart:
  • Smokers are at greater risk for diseases that affect the heart and blood vessels.
  • Increases in your blood pressure can also be caused by weight gain from excessive drinking.
  • Heavy drinking weakens the heart muscle, which means the heart can't pump blood as efficiently.
    • It's is known as cardiomyopathy and can cause death, usually through heart failure.

Concept-

• The stem is the ascending part of the axis bearing branches, leaves, flowers, and fruits.
• It develops from the plumule of the embryo of a germinating seed.
• The stem bears nodes and internodes. 
• The main function of the stem is spreading out branches bearing leaves, flowers, and fruits.
• It conducts water, minerals, and photosynthates. 

Explanation-

• Some stems perform the function of storage of food, support, protection, and of vegetative propagation. 
• The stem may not always be typically like what they are expected to be.
• They are modified to perform different functions.
• Underground stems of potato, ginger, turmeric, zaminkand, Colocasia are modified to store food in them.

Therefore turnip is not the stem.

Additional InformationTurnip

• Roots in some plants change their shape and structure and become modified to perform functions other than absorption and conduction of water and minerals.
• They are modified for support, storage of food, and respiration.
• Taproots of carrot, turnip, and adventitious roots of sweet potato, get swollen and store food.
