Answer:
how meiosis affects chromosome number
Answer: The new pressure of the gas is (A) 854.46 kPa.
The pressure of a given mass of gas at the absolute temperature 110 degrees K is 400 kPa.
The temperature is raised to 235 degrees K with constant volume.
Therefore,
Initial pressure 
Initial temperature 
Final temperature 
Final pressure
According to pressure law of gas,
( at constant volume)


Thus, the required new pressure of the gas is 854.46 kPa.

Answer:
Regulon
Explanation:
A regulon comprises of a group of operons that are controlled by the same regulatory protein referred to as a regulator which could act as a repressor or activator.
Regulons in bacterial cells are referred to as the fundamental unit of the response system. Regulons are majorly used when referring to prokaryotes that have their genome organized to operons, although this term is not limited to that. The genes that are found in a regulon are arranged into two or more operons at different regions on the chromosome.
