Answer:
Osmosis is the process cells use to move water molecules in and out of the cell through the cell membrane. When cells are put in different environments they will try to maintain an equilibrium with the water concentration outside the cell. Through osmosis the cell will lose or gain water molecules to become equal to the concentration in their environment.

Answer:
The correct answer is- Histone
Explanation:
DNA is approximately 2.2 m long thread which has to be adjusted in a microscopic nucleus so DNA must be in a supercoiled form to be present in the nucleus and this supercoiling of DNA is done on histone protein.
Histone protein is a positively charged protein that is made up of eight proteins so it is called histone octamer. Each histone has 2 copies of each protein that is H2A, H2B, H3, and H4.
DNA is negatively charged and histone protein is positively charged therefore DNA wraps around histone protein which causes the packaging of DNA. So the correct answer is histone protein.
