Explanation

Scientists estimate that 33% of the Earth’s area should be conserved.

This helps maintain biodiversity and ecological balance.

Protected areas include forests, wetlands, and marine zones.

Explanation

Restriction enzymes (also called restriction endonucleases) recognize specific DNA sequences.

These sequences are usually 4–8 base pairs long.

The enzymes cut DNA at or near these recognition sites.

They are widely used in molecular biology and genetic engineering.

Restriction enzymes allow scientists to manipulate DNA for cloning and analysis.

Explanation

S-waves are transverse seismic waves.

They cause particles to move perpendicular to the direction of wave propagation.

S-waves cannot pass through liquids or gases because these cannot support shear stress.

They only travel through solids, like the Earth’s crust and mantle.

This property helps scientists study the internal structure of Earth.

Explanation

When milk reaches the processing plant, it is poured into silos for storage.

Silos are large containers that keep milk fresh and uncontaminated.

They allow controlled temperature to prevent spoilage.

From silos, milk is later processed for pasteurization, packaging, and distribution.

Using silos ensures efficient storage and handling in the dairy industry.

Explanation

Sedimentation is the process where solid particles settle at the bottom of a liquid.

It is a primary method in water treatment.

Sedimentation removes suspended solids from water.

It helps in clarifying water before filtration.

This process is essential for providing clean drinking water.

Explanation

Drought causes reduced rainfall, drying out soil and plants.

Dry vegetation becomes highly flammable, increasing wildfire risk.

High temperatures further intensify fire outbreaks.

These factors together make wildfires more frequent and severe.

Therefore, drought-induced wildfires occur due to all of these factors

Explanation

The nucleolus is known as the factory of ribosomes.

The nucleolus is a dense region inside the nucleus.

It is responsible for producing ribosomal RNA (rRNA).

Ribosomes are assembled in the nucleolus before entering the cytoplasm.

Ribosomes play a key role in protein synthesis.

Explanation

Steel cans are coated with tin to prevent rusting and corrosion.

Tin provides a protective layer between steel and the beverage.

This ensures the drink remains safe and hygienic.
