KAS GK Questions and Answers

GENERAL SCIENCE

Tips For Cracking Science:

Hi learners,

One of the hallmarks of science is the ability to ask the question,"why?" and find a rational conclusion to things around us.For KAS we can expect questions around why a common phenomenon like oil rising up the wick occurs or why silica gels are used in packaging.Further a through revision of 10th standard physics,chemistry,and biology is necessary to answer the factual questions.A few current affairs related technology questions and answers, as well as questions related to Nobel prizes can also expected.

1. The lens used to rectify the disease,"Myopia" :
A. Convex lens
B. Concave lens
C. Biconcave lens
D. Biconvex lens
Ans : B. Concave lens

• Near -sightedness,also known as short-slightness and myopia,is a condition of the eye where light focuses in front of instead of on the retina.This causes distant objects to be blurry while close objects appear normal.A concave lens (minus powered) is placed in front of a myopic eye,moving the image back to the retina and clarifying the image.

2.Which of the following are assigned geographic indicator tag ?
i) Kerala's Nendran Banana
ii) Karnataka's rose onion
iii) Arunachal orange
iv) Tezpur Lichi
A. Only ii
B. ii,iii and iv
C. i and iv only
D. all of these
Ans : D. all of these

• Changalikodan nendran Banana of famously known as Changalikodan is a banana variety originated and cultivated in Chengazhikodu village of Thrissur district, Kerala. 
• Bangalore rose onion,locally called gulabi eerulli,is a variety of onion grown in and around Bangalore in Karnataka. it got the geographical indicationtag in 2015.Bangalore rose onions are grown in the districts of Bangalore Urban, Banglore Rural,Chikkaballapur and Kolar.
• Arunachal wakro orange has been registered under geographical indication registration along with eight other products from the North-East.Tezpur litchi is characterised by its distinct size,shape,color,flavor,taste, and juicy pulp and got GI tag in 2015.

3. A high Biological Oxygen Demand (BOD) indicates that ;

A. water is pure

B. Absence of microbial action

C. There is low level of microbial pollution

D. There is high level of microbial pollution

Ans : D. There is high level of microbial pollution

• Biochemical oxygen demand (BOD, also called biological oxygen demand) is the amount of dissolved oxygen needed (i.e.., demanded) by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period. So higher the biological oxygen demand,higher is the microbial pollution in the water.

4. "Dendrology" is associated with:

A. Animals

B. Trees

C. Man

D. Fish

Ans : B. Trees

• Dendrology is the study of wood plants; typically trees but there are other things such as shrubs and vines that bear similarities to trees, so they are studied as well. Dendrology is a science that studies,identifies,and even names plants that have woody structural systems.

5. Sodium bicarbonate is useful as a fire extinguisher because

A. it serves as a blanket for fire

B. it releases water which extinguishes fire.

C. it emits a foam which extinguishes fire

D. it decomposes on heating to give carbon dioxide,which extinguishes fire.

Ans : D. it decomposes on heating to give carbon dioxide,which extinguishes fire.

• Sodium bicarbonate ,regular or ordinary used on class B and C fires,was the first of the dry chemical agents developed.In the heat of a fire ,it releases a cloud of carbon dioxide that smothers the fire .That is,the gas drives oxygen away from the fire,thus stopping the chemical reaction.

6. Oil rises up the wick in a lamp,because of :

A. the liquid state of oil

B. the diffusion of oil through the wick

C. capillary action

D. volatility of oil

Ans : C. capillary action

• Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of,or even in opposition to,external forces like gravity.It occurs because of intermolecular forces between the liquid and surrounding solid surfaces.if the diameter of the tube is sufficiently small,then the combination of surface tension (which is caused by cohesion within the liquid) and adhesive forces between the liquid and container wall act to propel the liquid.Wicking is the absorption of a liquid by a material in the manner of a candle wick.

7. Which of the following is a wrong statement ?

A. All the minerals - are not ores

B. All the ores are not minerals

C. All the ores are minerals

D. From ores,metals can be extracted economically

Ans: B. All the ores are not minerals

• Minerals are naturally occuring incorganic solids with a crystalline structure and a definite range of chemical formula.Ores are concentrations of minerals in rock that are high enough to be economically extracted for use. Example Aluminium metal is found in two minerals: clay and bauxite.Aluminium metal is extracted only from bauxite in a convenient way.So,bauxite is an ore of aluminium.

8.A person climbing a hill bends forwards so as to

A. Increase stability

B. move faster

C. reduce chances of slipping

D. conserve stamina

Ans: A. Increase stability

• The person always bends forward when walking up the hill just to maintain  himself in stable equilibrium. By bending forward,the person tries to increase his base of support,so that the vertical line passing through his centre of gravity may still fall within the base.

iv) Across the placenta

A. i and iii are correct

B. i,ii and iv are correct
