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

The given image is showing the interaction of the enzyme and its substrate.
In the first part of the image, the enzyme and substrate are not bind together. They are present in close proximity. The enzyme shown in the picture have a site for the attachment of the substrates.
In the next picture, the interaction of the enzyme and the substrate has occurred, which resulted in the formation of the enzyme substrate complex. Hence, the given picture shows the interaction of an enzyme with the substrates.
I think the answer is most likely be J.
The first (F) one the population of the predator increases hugely while the population of the prey was neutral. And so both population didn’t seem to have any connection. Same goes for H. Graph G doesn’t make sense at all the population of the prey didn’t exist throughout the time in the graph but only exist in one single point of time and then just vanish again so that shouldn’t be the answer either.
In graph J, you can see the correlation between the two populations as the predator goes up and so does the prey.
You can search up on google predator-prey relationship graph to get better understanding.
