Endoplasmic reticulum is situated close to the nucleus and is involved
in protein synthesis. Rough ER has lysosomes around the edges.
Lysosomes - The cleaner of the cell. Small and numerous, increases
surface area and increases the rate at which waste products are removed
from the cell.
Chloroplasts - Made up of Grana, stacked up to increase surface area.
This allows more Chlorophyll to be made to increase the rate of
photosynthesis.
Nucleus - Information point of the cell</span>
The monomer must be able to form stable covalent chemical bonds between units in order to polymerize.
Answer is b. Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic.
Burning of fossil fuels release carbon dioxide and other harmful gases in the atmosphere. Carbon dioxide gets dissolves in the ocean to form carbonic acid. Due to formation carbonic acid, the pH of ocean water changes slightly. The average pH of ocean water was 8.2 slightly basic. Now it 8.1, it means there is 25 % increase in acidity of ocean water.
