Answer:
Option (c) is the correct answer.
Explanation:
It is known that if we have to convert temperature from kelvin to degree celsius then we have to subtract 273 from the given value of temperature.
Whereas when we have to convert temperature from degree celsius to kelvin then we have to add 273 in the given value of temperature.
Therefore, convert value of 200 Kelvin in the Celsius scale of temperature as follows.
Temperature = (200 - 273) degree celsius
= - 73 degree celsius
Thus, we can conclude that value of 200 Kelvin in the Celsius scale of temperature is - 73^{o}C.
To find the number of neutrons in an atom, you subtract the atomic number (number of protons) from the atomic mass (aproximate weight of an atom = neutrons + protons). Therefore the number of neutrons is:
166 - 46 = 120

Answer:
The major structural difference between chromatin and chromosomes is that the latter are more organized and condensed.
Explanation:
Chromatin is genetic material packaged into a complex by special proteins (histones). That complex is in the form of uncoiled structures, so chromatin fibers are long and thin. Chromatin structure is permissive to DNA replication, transcription and recombination events.
On the other hand, chromosomes are highly condensed structures of genetic material that are formed just before the cell division.
