Explanation

Bioremediation is the use of living organisms like bacteria and plants to remove or neutralize pollutants from the environment.

It is an eco-friendly method to clean up contaminated soil, water, or air.

Explanation

In the equation PV = nRT, R is the Universal Gas Constant, used in the ideal gas law.

Its value is 8.31 J/mol·K.

It links pressure, volume, temperature, and amount of gas.

Explanation

When θ = 0°, the force and displacement are in the same direction, and the work done is maximum.

The formula simplifies to W = F ⋅ d, meaning all the force contributes to the displacement.

Explanation

Explanation

Acetyl Co-A is the first carbon compound that enters the Krebs cycle, combining with oxaloacetate to form citrate.

It is produced from pyruvate during the link reaction before entering the cycle.

Explanation

The common phrase is: "Hard work is the key to success," meaning it is the main factor in achieving success.

"Key" symbolizes access or unlocking success through effort.

Explanation

اس کی بیماری اسے بستر تک محدود کر دیتی ہے۔

Explanation

Approximately means means قریب یا قریب ، عین مطابق نہیں

More or less means کم و بیش

Explanation

In most fungi, the nuclei are haploid (n) during the vegetative and asexual stages.

Diploid phase occurs briefly during sexual reproduction, followed by meiosis to restore haploidy.

Explanation

Friction always acts opposite to the direction of motion, resisting movement.

Since work = force × displacement × cos θ, and θ = 180°, cos 180° = –1, so work is negative.
