How is soil formed ????????????????????????????????????????????
- A.
  
  By cooling of volcanic rocks
- B.
  
  Weathering
- C.
  
  Insects
- D.
  
  Plant
- E.
  
  A and b
Correct Answer
E. A and b

Explanation
Soil is formed through a combination of processes, including weathering and the cooling of volcanic rocks. Weathering refers to the breakdown of rocks into smaller particles through physical, chemical, and biological processes. This process plays a significant role in soil formation as it helps to create the necessary conditions for plants and other organisms to thrive. The cooling of volcanic rocks also contributes to soil formation by providing a source of mineral-rich materials that can mix with organic matter and weathered particles to create fertile soil. Therefore, the correct answer is "a and b."

- D.
  
  5
- E.
  
  7
Correct Answer
C. 3

Explanation
There are three salivary glands in the mouth. These glands, known as the parotid, submandibular, and sublingual glands, are responsible for producing saliva, which helps in the digestion of food and keeps the mouth moist.

What is the theory of quantas called
- A.
  
  Theory of relativity
- B.
  
  Quantam theory
- C.
  
  Crystal theory
- D.
  
  A and b
- E.
  
  None OF THEse
Correct Answer
B. Quantam theory

Explanation
The correct answer is "quantum theory." Quantum theory is a fundamental theory in physics that describes the behavior of particles at the quantum level. It explains the discrete nature of energy and the wave-particle duality of matter and energy. The theory revolutionized our understanding of the microscopic world and is widely accepted in the scientific community. The theory of relativity, on the other hand, deals with the behavior of objects in the presence of strong gravitational fields or at speeds close to the speed of light. Crystal theory is not a recognized scientific theory.

The energy mass conversion is

Correct Answer
e = mc2

Explanation
The equation e = mc^2 represents the energy-mass equivalence in physics, as stated by Albert Einstein's theory of relativity. This equation shows that energy (e) is equal to the mass (m) multiplied by the speed of light (c) squared. It implies that mass can be converted into energy and vice versa. This equation has significant implications in understanding the relationship between mass and energy and has been confirmed through various experiments and observations.

What does c mean in physics
- A.
  
  Light
- B.
  
  Speed of light
- C.
  
  Square
- D.
  
  Cubic
- E.
  
  None
Correct Answer
B. Speed of light

Explanation
In physics, the symbol "c" represents the speed of light. The speed of light in a vacuum is a fundamental constant in physics, denoted by the letter "c". It is approximately equal to 299,792,458 meters per second. The speed of light plays a crucial role in various theories and equations in physics, such as Einstein's theory of relativity.

  4000
- B.
  
  100
- C.
  
  23000
- D.
  
  4500
- E.
  
  None
Correct Answer
D. 4500

Explanation
There are approximately 4,500 known species of mammals. This number includes a wide range of animals such as primates, rodents, carnivores, and marine mammals. Mammals are characterized by their ability to nurse their young with milk and have hair or fur on their bodies. The diversity of mammal species can be found in various habitats around the world, from the rainforests to the oceans.
