bears hibernate during the winter.
B)
the base of the food chain is seasonal.
C)
available energy is lost from one trophic level to the next.
D)
light that supports photosynthesis is limited during certain times of the year.
Answer:
The correct answer would be C) available energy is lost from one trophic level to the next.
It is the universal law that the energy is lost when transferred from one trophic level to the next.
It is because most of the energy present at any trophic level is used by the organisms for their biological processes such as locomotion, reproduction et cetera. Due to this, most of the energy is lost as heat in the surrounding environment.
In the given food chain, the bears are present at the highest trophic level and thus they would get minimum energy.
Thus, the ecosystem can provide only a limited amount of energy to the bears due to which the ecosystem can support a limited number of bears.

B) amino acids
C) nucleic acids
D) monosaccharides
Biology
Answer:
B) Proteins are linear polymers formed by linking the α-
carboxyl group of one amino acid to the α-amino group
of another amino acid with a peptide bond (also called
an amide bond )
Proteins are composed of chains of B) amino acids which are joined together with peptide bonds.
Proteins, the workhorses of biology, consist of long chains of amino acids linked by peptide bonds. These complex molecules play vital roles in nearly all biological processes. Amino acids, the building blocks of proteins, feature a central carbon atom connected to an amino group, a carboxyl group, a hydrogen atom, and a distinct side chain.
During protein synthesis, amino acids are linked via peptide bonds, a covalent connection between the carboxyl group of one amino acid and the amino group of another. The specific sequence of amino acids in a protein, known as its primary structure, dictates its unique three-dimensional shape and, consequently, its function within living organisms.

Answer:
chemicals
Explanation:
Answer:D: all the above
Explanation:
(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
