Quiz Answer Key and Fun Facts

1. Who finally proved the chromosome theory of heredity?

Answer: Thomas Morgan

2. In which field(s) can humans make use of ultrasound?

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.

3. What are the following called - Koch Curve, Sierspinski Sponge, Mandelbrot Set, Julia Set?

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!

4. The elements which are doped in Solar Cells are -

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.

5. According to relativity theory, only what has an absolute velocity?

Answer: light

6. A waterfall produces an even spread of all frequencies, making a hissing sound called _____ noise.

Answer: white

7. Organic compounds containing an amino group are called what?

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.

8. The study of materials at very low temperatures is called?

Answer: Cryogenics

The chief branches of Cryogenics include Superconductivty and Superfluidity.

9. Which of the following is a disaccharide?

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).

10. Which of the following is not a hominoid?

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.

11. Which vitamin is known as phylloquinone?

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.

12. Which of the following is an ungulate?

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.

13. DNA molecules are polymers because they consist of chains of similar units linked together. What are these units called?

Answer: nucleotides

14. How many kingdoms of living things are there according to US classification? (Hint: The UK uses one fewer)

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.

15. Which of the following stages in the life cycle of a star comes after the Main Sequence Period?

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.

16. What is the length of Tycho Crater on the moon?

Answer: 84 km

17. In electroplating, the substance to be coated is made the _____.

Answer: cathode

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

18. Specific Gravity is also known as -

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.

19. How many whole numbers are there in the pH scale (not counting zero)?

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.

20. To which kingdom of living things do amoeba and paramoecium belong?

Answer: protista

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

21. The Quantum Theory explains which effect?

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.

22. What is the Latin name of mercury?

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!

23. A sound with definite frequency is called which of these?

Answer: tone

24. Which of the following is a semisynthetic polymer?

Answer: Rayon

25. Solder is an alloy of -

Answer: Lead and Tin

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