D.
gas is reactive with the needle.
Ans:
needle exerts more pressure than nail on the balloon.
Explanation :
It is easy to burst a gas-filled balloon with a needle than with a nail because the needle applies more pressure than nail. Besides, the application of the pressure is on a small surface area than in the case of nail. In the case of needle, it is a very tiny area at the tip of the needle, so only a little force gives a lot of pressure (pressure = force/area).

[44] Allantois of Embryo helps in -
A.
digestion
B.
respiration
C.
excretion
D.
protection
Ans:
excretion
Explanation :
The allantois is the sac-like extra-embryonic membrane that removes waste from the embryo. As the embryo grows, so does the allantois, eventually pressing against the chorion. This allows the allantois to exchange oxygen and car-bon dioxide with the air out-side the e shell. In addition, the allantois also serves as a disposal site for uric acid.

[47] It is easy to burst a gas-filled balloon with a neelde than with a nail. It is because -
A.
nail is more longer than needle.
B.
nail exerts more pressure than needle on the balloon.
C.
needle exerts more pressure than nail on the balloon.
D.
gas is reactive with the needle.
Ans:
needle exerts more pressure than nail on the balloon.
Explanation :
It is easy to burst a gas-filled balloon with a needle than with a nail because the needle applies more pressure than nail. Besides, the application of the pressure is on a small surface area than in the case of nail. In the case of needle, it is a very tiny area at the tip of the needle, so only a little force gives a lot of pressure (pressure = force/area).

[49] Photoperiodism affects -
A.
All of these
B.
Flowering
C.
Vegetative growth
D.
Fruiting
Ans:
All of these
Explanation :
Photoperiodism is the developmental responses of plants to the relative lengths of light and dark periods. It affects the vegetative growth as well as the time of flowering and fruiting in plants. For example, some annual plan may be made to complete the life cycle twice in a year, with others can be made to take on characteristics of everlasting flowering species and continue to produce flowers and fruits on an indefinite period while in yet other species the plant may continue vegetable development indefinitely without flowering.

[38] The South-East trade winds are attracted towards the Indian subcontinent in the rainy season due to -
A.
the development of cyclone over the equator
B.
the effect of easterlies
C.
the effect of Northern-East trade winds
D.
the presence of low atmospheric pressure over North-West India
Ans:
the presence of low atmospheric pressure over North-West India
Explanation :
During the Rainy Season in India (Mid-June to the end of September), the intense heat that prevails in the Indian subcontinent causes a low pressure region over the Northern Plains in the North-western parts of the country. It is intense enough to attract the moisture; bearing winds from the Indian Ocean. Thus, the south-east trade winds from the Southern Hemi-sphere are attracted towards India. On crossing the equator, they are deflected to their right and blow over the Indian subcontinent as the south-west monsoon winds.
[39] The 'graded profile' of a river course is a -
A.
smooth curve from source to mouth.
B.
smooth curve in the upper course.
C.
smooth curve in the middle course.
D.

Ans:
smooth curve from source to mouth.
Explanation :
The course of a river from its source to its mouth is normally divided into 3 sections, namely upper, middle and lower courses. Action of the river on its valley from source to mouth in relation to the features developed by it is seen in the river valley profile, known as graded profile. Throughout the long profile of a river, deposition and erosion are balanced meaning that, given enough time, the river's long profile would become a. smooth, concave, graded profile from its source to mouth.
[40] Sink hole is a phenomenon of topography.
A.

Sea hares are molluscs. They belong to Phylum Mollusca and Class Gastropoda like snails. Like m y other sea slugs (Subclass Opistobran-chia), sea hares lack external shells as adults. Sea hares belong to Order Anaspidea.
[46] Animal protein is called first, class protein because it is -
A.
easily digestible
B.
delicious in taste
C.
cheaper in the market
D.
rich in essential amino acids.
Ans:
rich in essential amino acids.
Explanation :
Proteins from animals are called 'first class' proteins they provide all the essential amino acids, including those that the body can't make. Proteins from plants are second class' proteins.
[47] It is easy to burst a gas-filled balloon with a neelde than with a nail. It is because -
A.
nail is more longer than needle.
B.
nail exerts more pressure than needle on the balloon.
C.
needle exerts more pressure than nail on the balloon.
D.
gas is reactive with the needle.
Ans:
needle exerts more pressure than nail on the balloon.
Explanation :
It is easy to burst a gas-filled balloon with a needle than with a nail because the needle applies more pressure than nail. Besides, the application of the pressure is on a small surface area than in the case of nail. In the case of needle, it is a very tiny area at the tip of the needle, so only a little force gives a lot of pressure (pressure = force/area).
[48] The longest continental Rail way in the world is –
A.

Explanation :
Trans-Siberian Railway, that connects Moscow with the Russian Far East and the Sea of Japan, is the longest railway line in the world with a length of 9,289 km. There are connecting branch lines into Mongolia, China and North Korea.
[49] Photoperiodism affects -
A.
All of these
B.
Flowering
C.
Vegetative growth
D.
Fruiting
Ans:
All of these
Explanation :
Photoperiodism is the developmental responses of plants to the relative lengths of light and dark periods. It affects the vegetative growth as well as the time of flowering and fruiting in plants. For example, some annual plan may be made to complete the life cycle twice in a year, with others can be made to take on characteristics of everlasting flowering species and continue to produce flowers and fruits on an indefinite period while in yet other species the plant may continue vegetable development indefinitely without flowering.

The Lodi dynasty ruled for seventy five years from 1451-1526 till their last ruler Ibrahim Lodi was defeated and killed by 5-abur in the First battle of Panipat in 1526.
[44] Allantois of Embryo helps in -
A.
digestion
B.
respiration
C.
excretion
D.
protection
Ans:
excretion
Explanation :
The allantois is the sac-like extra-embryonic membrane that removes waste from the embryo. As the embryo grows, so does the allantois, eventually pressing against the chorion. This allows the allantois to exchange oxygen and car-bon dioxide with the air out-side the e shell. In addition, the allantois also serves as a disposal site for uric acid.
