The Scientific Spirit Trivia Quiz

Answer: Thomas Morgan

Answer: both

I needn't tell about the uses of ultrasound in engineering, you would already know this. In medicine, ultrasound is used to shatter kidney stones while the tissue reamains undamaged. Also it is used by doctors to examine the growing fetus in the womb.

Answer: fractals

Fractals are self-similar geometric figures, small parts of which look like the whole. Koch Curve is a linearly self-similar fractal - meaning it looks the same when magnified. The 2 sets are infinitely irregular. The Sierspinski Sponge is such an unusual figure that it is considered to be between 2-dimensional and 3-dimensional! It has infinite surface area but zero volume!

Answer: B, P

A typical solar cell is a 'pn' semiconductor junction based on silicon. The n-type material is doped with phosphorus and the p-type material, with boron. Sunlight produces pairs of electrons and holes, which are then split by the electric field created by the junction. The free electrons and holes can then move, creating an electrical current.

Answer: light

Answer: white

Answer: Amines

Most amines have a fishy smell, and many are important starting materials for producing everything from medicines to the chemical fertilizers used by farmers.

Answer: Cryogenics

The chief branches of Cryogenics include Superconductivty and Superfluidity.

Answer: Sucrose

Sucrose is common sugar. It is made of one unit of glucose and fructose(so totally - 2 units). Its molecular formula is C12 H22 O11. Other disaccharides include Maltose and Lactose. Glucose and Fructose are monosaccharides(1 unit). Starch and Cellulose are polysaccharides(many units).

Answer: Baboon

Apes (gorillas, chimpanzees, orangutans, gibbons, and humans) are known as hominoids. Hominoids have large, well-developed brains,which help them to adapt their behavior to changes in their environment.

Answer: K

Green vegetables and liver are its best sources. It is also synthesized in the body by intestinal bacteria although it cannot be used by the body.

Answer: Giraffe

Hoofed mammals are called ungulates. Hooves are in fact enlarged toenails, and ungulates are grouped according to whether they have an odd or even number of toes on each foot. Odd-toed ungulates include horses and zebras, which have a one-toed hoof. Even-toed ungulates include cattle, deer, and giraffes, which have two-toed hooves. Most two-toed ungulates are ruminants.

Answer: nucleotides

Answer: 6

They are 1) Plantae, 2) Animalia, 3) Bacteria (called Monera in the UK), 4) Fungi, 5) Protista and 6) Archaea. The latter two are not separate in the UK system.

Answer: Red Giant

The order of life cycle of stars is- 1)Nebula, 2)Protostar, 3)T Tauri Type, 4)Main Sequence, 5)Red Giant and after this phase the stars' fate depends on its mass.So, 6a) White Dwarf, 6b) Supernova . After white dwarf, it fades away into a black dwark. After a supernova, the fate of the core depends on its mass. So, 6b(i)) Neutron star, 6b(ii)) Black Hole.

Answer: 84 km

Answer: cathode

The cathode is the negative electrode. Metal ions move to it and are coated on the object.

Answer: Relative Density

The Specific Gravity of a material is its density divided by the density of water. Since it is a ratio, it has no units.

Answer: 14

pH stands for 'Potential for Hydrogen' also called 'Power of Hydrogen'. If the pH is below 7, the substance is acidic. If the pH is higher than 7, it is basic. Pure water has a pH of 7.

Answer: protista

If you typed 'Protozoa', it is wrong. To know why, see the Interesting Info in Q.14.

Answer: Photoelectric effect

Quantum theory suggests that light, UV Rays, Gamma Rays, Radio waves and other similar forms of radiation are composed of tiny packets of energy, called quanta (one packet is called a quantum), that behave like particles(in this case - the photon). The quantum theory explains the photoelectric effect like this - when metal surfaces are struck by electromagnetic radiation, they emit electrons. Each electron emitted has had energy transferred to it from an individual quantum of radiation(photon). Photoelectric effect If electromagnetic radiation hits a metal plate, electrons are emitted, provided the quanta hitting the plate have enough energy.

The energy of quanta depends on the frequency of the radiation.

Answer: Hydrargyrum

Hence the symbol - Hg. Aurum and Argentum are the Latin names of Gold and Silver, respectively. There is no such thing as Mercurium!

Answer: tone

Answer: Rayon

Answer: Lead and Tin

This alloy is called so because it is used in soldering joints.
