Question Discussion & Solution

Concept:

• Electric current is the rate of flow electric charge or free Electrons in a definite direction through any section of wire. Its SI unit is ampere(A).
• The direction of the conventional current corresponds to the direction of positive charge which is from higher potential(positive) to lower potential(negative).

I = Q / t

I is current, Q is charge, t is time

Explanation:

Q = I t

So Charge is the product of current and time.

Unit of current is Ampere, and unit of time is an hour. 

So, Amount of charge or Quantity of electricity is Ampere-hour 

The correct answer is Mr. Bulaki Das Kalla.

Explanation:

• Parenchyma, Sclerenchyma, and Collenchyma are the Simple Permanent Plant tissues.
• Xylem and Phloem are the Complex Permanent Plant tissue.
• Sclerenchyma: supporting tissue in higher plants.
• Parenchyma: makes up most of the cells within leaves, flowers, and fruits.
• Collenchyma: provides support, structure, tensile strength, and flexibility which helps the plant to bend.
• Xylem:
  • It is plant tissue that transports food water and other dissolved minerals from roots to other parts of the plant.
• Phloem:
  • The main function of the phloem is to transport food materials from the leaf to other parts of the plant.

Water Pollution:

• Water pollution occurs when harmful substances often chemicals or microorganisms contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment.
• Water pollution is a major environmental issue in India.
• The largest source of water pollution in India is untreated sewage.
• Other sources of pollution include agricultural runoff and unregulated small-scale industry.
• Most rivers, lakes, and surface water in India are polluted due to industries, untreated sewage, and solid wastes.

Hence, option 1 is the correct answer. 

​

​Untreated Sewage

• A 2007 study found that the discharge of untreated sewage is the single most important source of pollution of surface and groundwater in India.
• There is a large gap between the generation and treatment of domestic wastewater in India.
• The problem is not only that India lacks sufficient treatment capacity but also that the sewage treatment plants that exist do not operate and are not maintained.

1. Agriculture run-off: Farms discharge large quantities of agrochemicals, organic matter, drug residues, sediments, and saline drainage into water bodies. Nevertheless, agricultural pollution, aggravated by increased sediment runoff and groundwater salinization, is also becoming an issue.
2. Unregulated small-scale industries and religious practices comparatively have less contribution to water pollution in major rivers of India.

The correct answer is Rape.

• Section 376 of the Indian Penal Code deals with crimes related to Rape.

Key Points

• Section 376 of the Indian Penal Code:
  • It deals with the punishment related to sexual assault and harassment.

Additional Information

• Section 316 of The Indian Penal Code deals with Foeticide.
• Section 498 of The Indian Penal Code deals with Domestic Violence.
