Explanation

A biocatalyst is a protein that speeds up a biochemical reaction in a living organism, and the term "enzyme" specifically refers to a protein with this function. 

Explanation

A scientific theory is a well-substantiated explanation of some aspect of the natural world

Both scientific laws and scientific theories are typically well-supported by observations and/or experimental evidence. 

Additional Information:

Explanation

Knocking in an engine produces a sharp metallic sound due to premature combustion of the air-fuel mixture, which creates abnormal pressure waves.

Explanation

Yeast acts as a leavening agent, causing baked goods like bread to rise.

It feeds on the sugars in bread dough, which results in the release of carbon dioxide as a by-product.

This causes the dough to expand by creating bubbles within it.

Explanation

For a point source in 3D, amplitude is inversely proportional to the distance from the source:  

A ∝ 1/r  

So, if distance doubles (2r), amplitude becomes A/2.

Explanation

The zeroth law of thermodynamics states that if two thermodynamic system are each in thermal equilibrium with a third, then they are in thermal equilibrium with each other.

Explanation

There are four common types of bandages:

• Roller Bandage
• Triangular Bandage
• Tubular Bandage
• Adhesive Bandage

Explanation

 Radon is a radioactive noble gas that is used in radiotherapy for cancer treatment due to its ability to emit alpha particles, which can penetrate and damage cancer cells. 

Explanation

In simple harmonic motion (S.H.M), the restoring force is minimum at Mean position. 

The restoring force is directly proportional to the displacement from the mean position.

At the mean position, the displacement is zero, meaning the restoring force is also zero at that point. 

Explanation

Cartilaginous rings in the respiratory tract, like those in the trachea and bronchi, serve multiple functions: 

Support:

The rings provide structural support to the airways.

They keep the trachea and bronchi open and stable. 

Keep the passage open:

This is directly related to the support function.

Prevent collapsing:

The rings are crucial in preventing the collapse of the airways, especially during exhalation when pressure changes occur.
