Answer:
Number of nucleosomes in
bp is equal to 
Explanation:
For wounding one nucleosome, total length of DNA required is equal to
bp
The length of linker DNA in mammals is equal to
bp
Thus , the total length of DNA that confides between two nucleosome is equal to the sum of wounding length of DNA and the linker length
bp
Thus, in
bp length of DNA, the total number of nucleosomes is equal to 
Thus, number of nucleosomes in
bp is equal to

Air pressure (inside the lungs) is lowest when lung volume is highest, so the answer is B. when you breathe in your lungs expand, which makes the air molecules spread out, therefore the pressure is lower.
Heat from the air will move into the ice cream
