Explanation

Motor neurons carry impulses away from the central nervous system to effectors like muscles or glands.

They are responsible for triggering responses such as muscle movement.

Explanation

Neurons transmit messages through electrical impulses (action potentials) and chemical signals (neurotransmitters), forming an electrochemical wave.

These signals travel across the neurons and synapses to communicate information throughout the body.

Explanation

Sea caves are formed when sea waves erode the base of a cliff, creating deep depressions in the rock.

These caves are typically shaped by the continuous action of water eroding the rock over time.

Explanation

A mirage occurs when light bends due to varying air temperatures, causing total internal reflection.

This makes distant objects appear as if they are reflected in water, commonly seen in deserts.

Explanation

Distillation is a technique used to separate a volatile substance (which evaporates easily) from a non-volatile substance by heating the mixture and condensing the vapor.

It is commonly used to purify liquids or separate components based on their boiling points.

Explanation

بنیادی طور پر شہری اور صنعتی علاقوں میں ہوائی آلودگی زیادہ ہوتی ہے کیونکہ ان علاقوں میں گاڑیوں، فیکٹریوں اور دیگر صنعتی سرگرمیوں سے زہریلے گیسوں کا اخراج ہوتا ہے۔

یہ آلودگی فضا میں موجود ہوتی ہے اور انسانوں اور ماحول کے لیے نقصان دہ ثابت ہو سکتی ہے۔

Explanation

A solution is a homogeneous mixture where two or more substances are evenly distributed.

It consists of a solute (dissolved substance) and a solvent (the substance in which the solute dissolves).

Explanation

Explanation

Animals are biotic components of the environment because they are living organisms.

Soil, Sun, Water, and Temperature are abiotic components as they are non-living factors that influence ecosystems.

Explanation

The state of inactivity in animals during summer or dry season is called aestivation (or estivation).

Purpose: To conserve energy and prevent water loss during arid, high-temperature conditions.

Duration: Lasts for the duration of the hot/dry season, ranging from weeks to months, or even years in some cases.
