Answer:
The correct answer is option b. "20 H1, 40 H2A".
Explanation:
Chromatin is a complex that protects and condenses the genetic material comprised of DNA and proteins. When chromatin is in the form of a 30 nm fibril, nucleosomes have a regular positioning along the DNA. This means that each nucleosome is associated with a single H1 molecule. Therefore a chromatin containing 20 nucleosomes will have 20 copies of H1 and 40 copies of H2A, because each nucleosome has 2 copies of the core histone H2A.

Answer; 
The second cell would not be able to produce as much food because it could not capture sunlight.
Explanation;
The first cell has multiple chloroplasts, and the second cell has very few which means the cell with more chloroplasts would make more food.
Chloroplast is an organelle is the cell where the process of photosynthesis (process in which plants make their own food) takes place.
A cell with multiple chloroplasts would make more food through photosynthesis compared to a cell with few chloroplasts.
