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.

Clouds are grouped by height and shape into high, middle and low families, but stratus, nimbostratus and stratocumulus are low clouds, not high ones.

The First and Ninth Plans gave top priority to agriculture, and the Seventh Plan's slogan was food, work and productivity.

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.

A nerve impulse is carried by the movement of sodium ions into the nerve cell and potassium ions out of it.

Lemon juice is acidic and rich in vitamin C, which together slow the enzyme reaction that browns cut apple. When an apple is cut, the enzyme polyphenol oxidase in its cells meets oxygen in the air and oxidises the fruit's phenolic compounds into brown pigments (melanins).

The Cabinet resolution that set up the Planning Commission in March 1950 named both aims.

In a micelle it is the long hydrocarbon tail that points into the oil droplet, while the ionic end faces outward into the water, so statement D reverses the real picture.

Light from the bottom bends as it passes from water into air, so the bottom seems nearer than it really is.

The heat given out by 2 g of steam equals the heat taken in by 250 g of water, and that balance gives L = 550 Cal/g. The water warms from 20°C to 25°C, so it absorbs 250 × 1 × 5 = 1250 Cal.

The national conference on AI and Ayurveda was held under this title at ITRA Jamnagar alongside the institute's sixth Foundation Day.
