32. An electronic diode using a semi-conductor nanoparticle material synthesised by microorganisms has been recently fabricated by Indian scientists for the first time, having utility in device miniaturization. The organism used is a/an — [U.P.P.C.S. (Mains) 2002]

Correct Answer: (c) Yeast
Solution:An electronic diode using a semiconductor nanoparticle material (cadmium sulphide) synthesized by microorganisms has been recently fabricated by Indian scientists for the first time with the help of yeast Schizosaccharomyces pombe having utility in device miniaturization. The diode was created by using this cadmium sulphide with phenylene vinylene.

3. Helium

4. Carbon dioxide

Select the correct answer using the codes given below :

Correct Answer: (a) 1 and 2
Solution:

Anaesthetic substances are mainly used for decreasing the sensation or awareness. William Mortan has used it for the first time in 1846 in the form of di-ethyl ether. In 1847, Jams Sampson used chloroform as an anaesthetic. Chloroform, Nitrous oxide, pentothal sodium, halothien, chloropropane, cocaine etc. are used as an anaesthetic.

36. Which one of the following pairs is correctly matched? [U.P. Lower Sub. (Mains) 2015]

Correct Answer: (d) Neurology - Nervous System
Solution:

Neurology is a branch of medicine dealing with the disorders of the nervous system. Cardiology is a branch of medicine dealing with the disorders of the heart as well as parts of the circulatory system.

Gastroenterology is the branch of medicine focused on the digestive system and its disorders. Urology is the branch of medicine that focuses on surgical and medical diseases of the male and female urinary tract system and male reproductive organs.

37. Which one of the following is not banned for use as performance enhancing substance by the athletes : [U.P.P.C.S. (Mains) 2003]

Correct Answer: (d) Colostrum
Solution:

Colostrum has been marked as a safe dietary supplement by the International Olympic Committee and it can be used as performance enhancing substance by the athletes. The other options are banned for use by the athletes.

38. Which one of the following pairs is not correctly matched? [U.P.P.C.S. (GIC) 2017]

CompoundClassification
(a) SaccharinCarbohydrate
(b) AdrenalineHormone
(c) ThiamineVitamin
(d) KeratinProtein
Correct Answer: (a)
Solution:

Saccharin is a white crystalline, slightly water-soluble powder, produced synthetically, which is used as an artificial sweetener. It is about 300-400 times as sweet as sucrose. It is unrelated to the carbohydrates. Pairs of other options are correctly matched.

39. Which one of the following pairs is not correctly matched? [U.P.P.C.S. (Mains) 2003]

Correct Answer: (d) Antiseptic - Phenolphthalein
Solution:Phenolphthalein is often used as an indicator in acid-base titrations. It is also used as laxative, not as antiseptic. So option (d) is not correctly matched.
