Explanation

Plastic is primarily made from petrochemicals, including oil and natural gas.

They are processed to create synthetic polymers used in manufacturing.

Explanation

ATP (Adenosine Triphosphate) is a molecule that stores energy in the form of phosphate bonds.

It is often referred to as the "energy currency" of the cell, as it can be easily converted into other forms of energy that are needed by the cell.

Explanation

Necrosis is a type of cell death caused by external factors such as injury, infection, toxins, or lack of blood supply.

It is a premature and uncontrolled death of cells, often resulting in inflammation and tissue damage.

Explanation

A community refers to all the different species living in a specific habitat or area, interacting with each other and their environment.

It includes plants, animals, microorganisms, and even fungi.

While A localized group of organisms that belong to the same species is

called a population.

Explanation

A short circuit is a condition where the resistance of a circuit is zero, or very close to zero.

This occurs when there is a direct connection between two points in a circuit, bypassing any resistance or load.

As a result, the current flows freely, and the voltage across the circuit is zero.

Explanation

Coulomb's Law most closely resembles Newton's Law of Gravitation.

• Both laws deal with forces between objects
• Both forces decrease with distance (inverse-square law)
• Mathematical formulas are similar in structure

F = k × (q1 × q2) / r^2 (Coulomb's Law)

F = G × (m1 × m2) / r^2 (Newton's Law of Gravitation)

Explanation

In simple harmonic motion (SHM), the object's maximum speed occurs when it passes through the equilibrium point, which is the midpoint of its oscillation.

Explanation

Surfactants reduce the surface tension of water, which is the energy required to create a surface between water and air.

By reducing surface tension, surfactants make it easier for water to spread and penetrate surfaces, which is important for cleaning and other applications.

Explanation

During alcoholic fermentation, yeast converts sugars in the dough into carbon dioxide gas (CO2) and ethanol (ethyl alcohol).

The CO2 produced gets trapped in the dough, causing it to expand and rise.

This process is responsible for the light and airy texture of bread.

Explanation

The tricep brachii is a large muscle in the back of the upper arm, responsible for extending (straightening) the elbow joint.

It has three heads (hence the name "tricep"), which originate from the scapula and humerus bones.
