The Banjaras were travelling traders and carriers who moved goods across the country on long caravans of pack oxen. Their caravans, called tanda, could have thousands of bullocks carrying grain, salt and other goods from the countryside to towns and markets.

Prokaryotic cells such as bacteria have no membrane-bound organelles, so they lack mitochondria. Prokaryotes have no true nucleus: their DNA lies in a region called the nucleoid, and they have no mitochondria, chloroplasts, endoplasmic reticulum or Golgi body.

From south to north the order is Bhadra (Karnataka), Simlipal (Odisha), Pachmarhi (Madhya Pradesh) and Shikari Devi (Himachal Pradesh). Bhadra lies in the Western Ghats of Chikkamagaluru district, Karnataka, at about 13.5°N, and is a tiger reserve.

Chalk, limestone and marble are all forms of calcium carbonate, CaCO₃. Chalk is a soft, porous rock built from the tiny shells of marine plankton.

The enzyme that makes most of the cell's ATP, ATP synthase, sits in the inner mitochondrial membrane along with the electron transport chain.

The Tropic of Cancer (23.5°N) passes through eight Indian states, and Manipur is not one of them; it lies just to the north.

Leucoplasts are colourless plastids that store food: starch, oils and proteins. Plastids are found only in plant cells and some algae, and they are of three main kinds.

Silver turns black in air because it reacts with sulphur compounds, mainly hydrogen sulphide, to form a thin black coating of silver sulphide (Ag₂S).

In the alkane series the boiling point rises as the carbon chain gets longer, and this order goes from 3 to 4 to 5 to 8 carbons.

An electron's mass is about 1/1836 of a proton's, which is roughly 1/2000. The electron has a mass of about 9.1 × 10⁻³¹ kg, while the proton has about 1.67 × 10⁻²⁷ kg, nearly 1,836 times heavier.

SONAR uses sound waves under water to find the distance and direction of objects. A SONAR set on a ship has a transmitter that sends out pulses of ultrasound and a detector that picks up their echo from the sea bed, a shoal of fish, a wreck or a submarine.

The sulphide ion has 16 + 2 = 18 electrons, and its mass number of 32 is its count of nucleons.

Rutherford's gold foil experiment showed that an atom's positive charge and almost all its mass sit in a tiny central nucleus.

Tendons are made of tightly packed parallel bundles of collagen fibres, which give them great pulling strength. Collagen is the most abundant protein in the human body.

AIDS is caused by HIV, a retrovirus whose genome is two copies of single-stranded RNA. After HIV enters a helper T-cell (CD4 cell), its enzyme reverse transcriptase copies the viral RNA into DNA, which is then built into the host cell's own DNA.

The Shamal is a hot, dry north-westerly wind that blows over Iraq and the Persian Gulf, the old land of Mesopotamia.

Its network of membrane tubes and sheets forms channels that carry materials, especially proteins, between parts of the cytoplasm and the nucleus.
