Answer: to help in cell division in animals
Explanation:
Photograph 51 is the nickname given to an X-ray diffraction image of crystallized DNA taken by Raymond Gosling in May 1952, working as a PhD student under the supervision of Rosalind Franklin, at King's College London in Sir John Randall's group. It was critical evidence in identifying the structure of DNA.
The right answer is B. Chromosome
In its most scientifically rigorous definition, a chromosome is a fully condensed structure of chromatin.
In optical microscopy, condensed regions formed of heterochromatin and decondensed regions of euchromatin are distinguished on the chromosomes. The genes expressed are located mainly at the level of euchromatin.
When a cell is subject to a solution that is equal in water concentration as inside the cell, the movement of water via a process called osmosis will equalize and the solution is said to be isotonic to the cell. That means the amount of water entering the cell from the solution will equal the water exiting the cell; no net water movement.
Answer:
It has to do with the body. So, B
