1. a. Usage of groundwater efficiently

2. d. All of the above

3. b. NO

4. d. All of the above

5. d. All of the above

Correct option is D) Hailes

1. The average weather pattern taken over a long time, say 25 years, is called climate of that place. 

2. Broadly, the same patterns of temperature, rainfall, humidity wind speed that have been generally continuing for a long time, say the last 25 years, at a place gives the climate of that place. 

3. If we find that temperature at a place is generally high for large part of the year, we say the climate of that place is hot.

Correct option is D) Thunder stroms

Increasing the harvest yields, improving soil structure, better water relation, economical, eco – friendly and more efficient farms are due importance of biofertilizer.

Correct option is A) wetness of the soil
 

1. Farmers estimate the rainfall based on the wetness of the soil after the rain. 

2. They call-it as “PADUNU”. 

3. This much of rainfall is sufficient to start agriculture activities like ploughing. 

4. This is an approximate measure.

Choosing of rulers in ‘janapadas’ – Men were chosen ‘rajas’ by performing big sacrifices. The ‘Ashwamedha was one such ritual that was used to identify a ‘raja’. The ‘raja’ chosen by this sacrifice was considered very powerful.

Electing rulers today – Today, we have a democratic system of government. Each citizen has a right to cast his vote and to form the government through his elected representative.

Correct option is A) Rain gauge

1. hunter-gatherers

2. the skin of animals and leaves

3. the skin of animals and leaves

4. water

5. sacred

6. hunter-gatherers

7. archaeologists

8. bamboo

9. Neolithic stone tools

10. Neolithic period

The given pair of equations is 

12x + 17y = 53 ……..(i) 

17x + 12y = 63 …….(ii) 

Adding (i) and (ii), we get 

29x + 29y = 116 

⇒ x + y = 4 (Dividing by 4) 

Hence, the value of x + y is 4.

(B) Rabindranath Tagore

The hunter-gatherers got their name from the way in which they lived. They used to gather food either by hunting animals or gathering food from the forests.

C) Both A & B are correct

B) 1 – A, 2 – E, 3 – D, 4 – B, 5 – C

Answer is (A) West

The hunter-gatherers spent their leisure time paintings. They painted pictures of humans, animals and hunting scenes on the walls of the caves and on rock shelters. Different colour stones were used and mixed with animal fat to prepare colours. They used bamboo brushes to paint on rocks and walls.

1. The rock shelters which have the paintings of the early people are called rock art sites.

2. Srikakulam, Vizianagaram, Visakhapatnam, East Godavari and Krishna districts have no rock sites.

3. Kurnool district

A) Only A is correct

(B) Visakhapatnam District

D) Deciduous forests grow in the areas which receive more and less rains.

(D) Both A & B are wrong

(A) Andhra Pradesh

D) Both A and B are wrong

Chintakanta is in Muddunur Mandal of Y.S.R. Kadapa District. There are ten rock shelters near it that have paintings of early people. There are more than 200 paintings in white and red colour. But there are only ten white paintings. In the red colour paintings, humped oxen are found in only one cave, which is locally called Eddula  Aavula Gundu. In the remaining paintings, we can see pictures of deer, stag, fox, rabbits, birds, human beings, etc.

(B) C and D are wrong

(B) 1 – c, 2 – e. 3 – a, 4 – b, 5 – d

(D) Lambasingi

Answer is (D) East

In Andhra Pradesh state majority of high landforms are hills

(C) Both A and B are correct

Answer is (B) Cold

C) Both A and B are correct

The value of cos1 + Cos2 + cos3 = 0

Explanation:

Sin1 +Sin2 + Sin3 =3
The maximum value of sin(x) is 1. The value of 3 can only be obtained if all the sin angle takes the value of 1.

So, Sin1 = Sin2 = Sin3 = 1

We can conclude that

1 ~ 2 ~ 3 ~ 90°

So, cos1 + Cos2 + cos3 = cos90° + Cos90° + cos90°= 0 + 0 + 0 = 0

Organic horizon is generally absent in deserts because of low content of organic matter due to scarcity of plant and animal remains or excreta.

Soil formation is initiated by the biological weathering process. Biological weathering takes place when organisms like bacteria, fungi, lichens and plants help in the breakdown of rocks through the production of acids and certain chemical substances.

Mutualism is an interaction between two species of organisms in which both are benefitted from the obligate association. 

E.g: Lichens (alga with fungus).

Sandy soil has a high porosity leading to decreased water retention hence unfit for cultivation.

1. Mutualism – E.g: Lichen 

2. Commensalism – E.g: Orchids.

The interaction between organisms, when continues for generations, involves reciprocal changes in genetic and morphological characters of both organisms. This type of evolution is called Co-evolution. It is a kind of co-adaptation and mutual change among interactive species.

Examples:

• Corolla length and proboscis length of butterflies and moths (Habenaria and Moth). 
• Bird’s beak shape and flower shape and size.

The plants which are found growing on other plants without harming them are called epiphytes. They are commonly found in tropical rain forest The epiphytic higher plant (Orchids) gets its nutrients and water from the atmosphere with the help of their hygroscopic roots which contain special type of spongy tissue called Velamen. So it prepares its own food and does not depend on the host. They use the host plant only for support and does not harm.
