(a) The whole structure is made up of stone and marble with
each of them having engraved astronomical scale. It consists of fourteen geometric
devices, used for measuring time, forecasting weather changes, predicting behaviour of planets
and finding extraterrestrial altitudes which attracts architects, historians and scientists
from all over the world.
(b) Iantar Mantar was built by Maharaja Sawai Jai Singh-II
of Jaipur in 1710 AD. Jantar Mantar finally got the status of a national monument in
1948.
(c) Maharaja Jai Singh was a fanatical astronomer who felt
that the tables used by pundits were deceptive and the actual planetary changes and
predictions of eclipses would not be possible through these measuring parameters. He wanted an
improved and efficient means through which exact predictions could be made. So, he
gave shape to such an instrument.
(d) Iantar Mantar consists of 14 geometric devices which are
fixed and point to a specific direction. The largest device or instrument is the ’Samrat
Iantar’ which is 90 feet high and its shadow is plotted in such a manner that it shows the
exact time of the day.
(e) (i) ancient
(ii) devices
(iii) perception
(iv) astronomical

Answer:
Sixteen years old is the age where the biggest difference between the average height of boys and girls can be observed. This is a difference of approximately 5.7 cm.
Explanation:
As we know, for biological reasons, boys and girls have different growths and different development in their bodies. However, the growth and development of boys and girls during childhood is very similar and only starts to look different even from adolescence, where individuals have great structural differences.
At 16 years of age, boys and girls have the greatest mean difference in height. While in previous years this difference was on average 1 centimeter, at 16 years old, girls are 150.8 cm tall on average, while boys are 156.5 cm tall.

One example that is not a behavioral adaptation in plants is tree roots growing downward because of gravity. The correct option is B.
Behavioral adaptation is what creatures do to survive. If we are talking about animals, the behavior can be acquired and carried down over generations, or it can be an innate adaption, which entails adaptions being passed down through generations genetically.
Individual organisms or entire groups can benefit from behavioral adaptations. Behavioral adaptations are actions taken by a plant to increase its chances of survival. Tropisms are an example of a behavioral adaptation in plants. Tropism refers to plant growth toward sunlight.
Roots growing downward due to gravity is not an adaptation because it is a natural cause, adaptations are the ones that save them from extreme conditions.
Therefore, the correct option is B.
