Answer: For most of the life the chromosomes exists in a loose noodle like structure. They become compact to fit into a very small space.
Explanation: The chromosomes consists of a very long DNA that is linear. The liner DNA also has many proteins associated with it which is called as histone proteins.
These proteins fold and gets packed into a compact form from loose noodle or thread like structure.
This is necessary to get into a compact structure because being in linear form would require much space which is not possible. So as to manage the space and many processes like replication, repair and gene expression it is necessary for the chromosomes to get compact.
The statement that best describes the graph of the relationship between the volume and temperature is; "It is a straight line with a positive slope showing that an increase in temperature results in an increase in volume."
The graph of volume against temperature is used to demonstrate Charles law. This law states that, the volume of a given mass of gas is directly proportional to its absolute temperature at constant pressure.
According to this law, the volume increases as temperature increases. This is the meaning of the positive slope of the straight line graph.
Hence, the statement that best describes the graph of the relationship between the volume and temperature of an enclosed gas is "It is a straight line with a positive slope showing that an increase in temperature results in an increase in volume."

Answer:
[H⁺] = 1.8 ×10⁻⁴ mol/L
Explanation:
Given data:
pH of HNO₃ = 3.75
[H⁺] = ?
Solution:
Formula:
pH = -log [H⁺]
Now we will put the values.
3.75 = -log [H⁺]
[H⁺] = 10⁻³°⁷⁵
[H⁺] = 1.8 ×10⁻⁴ mol/L
