Free trade refers to the unrestricted exchange of goods and services between countries without artificial barriers like tariffs, quotas, or import licenses. It is based on the principle of comparative advantage and promotes efficiency through competition. The term 'free' means absence of government restrictions, not that goods are cost-free or duty-free.

Neonatology is the branch of medicine concerned with the care and treatment of newborn infants. The other terms refer to different fields like shell study or worm study.

Jupiter is the largest planet in our solar system, with a mass more than twice that of all the other planets combined.

The term 'gene' was coined by the Danish botanist Wilhelm Johannsen in 1909 to describe the fundamental physical and functional unit of heredity.

GM food stands for Genetically Modified food, which refers to organisms whose genetic material has been altered using genetic engineering techniques.

Snakes possess a very high number of ribs, often ranging from 200 to 400 pairs, which support their elongated body structure and locomotion.

Proteins are essential for the growth and repair of body tissues, making them the most critical nutrient for children during their rapid growth phase.

The liver produces bile, which emulsifies fats, but bile does not contain digestive enzymes. The other listed organs all secrete specific enzymes for digestion.

The Hoolock Gibbon is the only ape species found in India, specifically in the northeastern states including Assam and Nagaland.

The UN General Assembly declared October 2, Mahatma Gandhi's birthday, as the International Day of Non-Violence to honor his legacy of peaceful resistance.

Bleaching powder (calcium hypochlorite) is widely used to disinfect and sterilize water by releasing chlorine, which kills pathogens.

Carbon dioxide (CO2) is used in fire extinguishers because it is denser than air and displaces oxygen, effectively smothering the fire. It also does not conduct electricity, making it safe for electrical fires. Carbon monoxide is flammable, carbon suboxide is not used in extinguishers, and sulfur dioxide is not a standard extinguishing agent.

Lead-acid batteries, commonly used in vehicles, utilize sulphuric acid as the electrolyte.

LPG (Liquefied Petroleum Gas) is primarily composed of propane and butane, which are easily liquefied under moderate pressure for storage.

A wound-up watch spring stores energy due to its position or configuration, which is the definition of potential energy (specifically elastic potential energy).

Nitrogen makes up approximately 78% of Earth's atmosphere, making it the most abundant gas.

Weightlessness in orbit occurs because the spacecraft and everything inside it are in a state of continuous free fall, meaning they are accelerating toward Earth at the same rate as gravity.

A 'therm' is a unit of heat energy, equivalent to 100,000 British thermal units (BTUs).

Radiation is the transfer of energy through electromagnetic waves, which is how the Sun's energy travels through the vacuum of space to reach Earth.

Newton's first law, also known as the law of inertia, states that an object will remain at rest or in uniform motion unless acted upon by an external force. Inertia is the inherent property of matter that resists changes in its state of motion.

Refraction is the bending of light as it passes from one medium to another, such as from water to air. This change in direction causes objects submerged in water to appear at a shallower depth than they actually are.

Silviculture is the branch of forestry concerned with the cultivation, development, and care of forest trees. It focuses on managing the establishment and growth of forest crops.
