The Atacama Desert in northern Chile is the driest non-polar desert on Earth; some of its weather stations have recorded almost no rain for years.

In photosynthesis, the oxygen released into the air comes from water molecules that are split using light energy. Photosynthesis takes place in the chloroplasts of green plants.

Pure iron melts at about 1,538°C, so 1,500°C is the only option close to its melting point. Iron is a metal with strong metallic bonds, so a great deal of heat is needed to break up its solid structure.

Blood is a fluid connective tissue, with cells floating in a liquid matrix called plasma. Connective tissues link and support other parts of the body, and they have cells spread out in a matrix.

Tripura shares an international border with only one country, Bangladesh, which surrounds it on three sides. Tripura's border with Bangladesh is about 856 km long, and on its remaining side it touches only the Indian states of Assam and Mizoram.

Current multiplied by resistance gives voltage, by Ohm's law, not electrical power. Electrical power is the rate at which electrical energy is used, and its basic formula is P = VI, where V is the potential difference and I is the current.

The rebel proclamations (ishtahars) recalled Mughal rule as a time when Hindus and Muslims lived together in harmony. During the Revolt of 1857, rebel leaders issued many proclamations and notices.

Potential energy is the energy a body stores because of its position or because its shape has been changed. A body raised to a height h has gravitational potential energy equal to mgh, where m is its mass and g is the acceleration due to gravity.

The Danish East India Company set up its first settlement at Tranquebar, now Tharangambadi, on the Tamil Nadu coast in 1620.

DNA copies itself from loosened chromatin, and chromatin condenses into chromosomes before division, but prokaryotes divide differently from eukaryotes. In a non-dividing eukaryotic cell, DNA lies in the nucleus as a loose network called chromatin.

Bronchioles are the fine branches of the airways in the lungs, and their walls have no cartilage. Cartilage is a firm but flexible connective tissue.

This is false, because most antibiotics, starting with penicillin, come from microbes. Alexander Fleming discovered penicillin in 1928 from the mould Penicillium notatum, which stopped the growth of bacteria around it.

The doldrums are the calm equatorial low-pressure belt, and the chinook is a warm, dry winter wind that raises temperatures quickly.

Oxygen-rich blood from the lungs returns through the pulmonary veins into the left auricle (left atrium) of the heart. The human heart has four chambers: two upper auricles (atria) that receive blood and two lower ventricles that pump it out.

Sound travels through water at about 1,480 metres per second at 20°C, which rounds to 1,500 m/s. Sound is a mechanical wave and needs a medium.

Osmosis is the movement of water from a dilute solution to a more concentrated one across a selectively permeable membrane.

The Krishna Raja Sagara (KRS) dam is built across the Kaveri near Mandya, close to Mysuru in Karnataka. The dam was built between 1911 and 1932 under the Maharaja of Mysore, Krishnaraja Wadiyar IV, after whom it is named.
