Question Discussion & Solution

The Correct Answer is Option (2) i.e Pancreas.

Key Points

• In humans, the kidney is one of the main organs of the excretory system.
• The kidney's function is the filtration of the blood and removing waste(toxic) products.
• Waste products and excess fluid are removed through the urine.
• If the kidney fails person needs to undergo dialysis.
• Dialysis is a treatment that filters and purifies the blood using a machine
• The human excretory system includes certain organs that eliminate the wastes such as salts, carbon dioxide, urea, uric acid and water produced by the body.
• The path of the urine in the human excretory system is -
• After filtering from the kidney → The urine through Ureter → Stored in the Urinary bladder → Exits through the urethra.

Important Points

• The Pancreas is an organ located in the abdomen. It is not a part of the human excretory system.
• The Pancreas plays an important role in converting the food we eat into fuel for the body's cell.
• It helps in the process of digestion. It also regulates blood sugar.
• The body system that removes metabolic wastes from the body is known as the 'Excretory System'.

The correct answer is Musca domestica.

• The scientific name of Housefly is Musca domestica.

Additional Information 

The logic is:

In the first letter E is added six then we get K similarly in the second letter F is added six the

we get L.

Similarly, in the first letter T is added six then we get Z and in the second letter U is added six then we get A.

Key Points

• Protection of Women from Domestic Violence Act, 2005:
  • Domestic Violence means:
    • “Physical abuse" includes hurt of any kind. Assault, criminal intimidation and criminal force. Hence statement 1 is correct.
    • “Sexual abuse" such as the conduct of a sexual nature such as forced sexual intercourse, forcing the aggrieved person to watch pornography or other obscene material
    • “Verbal and emotional abuse" such as Accusation/aspersion on character or conduct. An insult for not bringing dowry, Insult for not having a male child. Hence statement 2 is Correct.
    • "Economic abuse" such as not providing money for maintaining a woman or her children. Not providing food, clothes, medicine. etc, Forcing woman out of the house. Hence statement 4 is Correct.
  • Non-sharing of household work, noncaring attitude for children, unhealthy habits of living. late coming etc. (of the male partner) is not directly covered under this act. Hence Statement 3 is Incorrect.

CONCEPT:

• Power: The rate of work done is called power.
  • It is denoted by P.
  • Mathematically it is written as

\(Power\;\left( P \right) = \frac{{\;W}}{{t}}\)

CALCULATION:

Given - mass of 1^st person (m₁) = 80 kg, mass of 2^nd person (m2) = 60 kg, time (t₁) = 12 sec, and time (t2) = 11 sec​

• The power to take an object to a certain height in 12 sec by 1^st person is 

\(\Rightarrow P_1 = \frac{mgh}{t}=\frac{80gh}{12}\)       ----(1)

• The power to take an object to a certain height in 11 sec by 2^nd person is 

\(\Rightarrow P_1 = \frac{mgh}{t}=\frac{60gh}{11}\)       ----(2)

On dividing equations 1 and 2, we get

\(\Rightarrow \frac{P_1}{P_2} =\frac{\frac{80gh}{12}}{\frac{60gh}{11}}=\frac{11}{9}\)
