<span>Nitrogen and phosphorous are the most prevalent aquatic pollution and contribute heavily to the excessive growth of algae in aquatic environments called algae blooms. The nitrogen from the fertilizers is found in molecules called nitrates which are compounds of both oxygen and nitrogen. Phosphorous helps algae to absorb carbon dioxide. So when the phosphorous levels are high the algae absorbs more carbon dioxide, which allows for faster photosynthesis and faster glucose production which leads to faster growth. Although algae need both nitrogen and phosphorous to grow, when the levels are too high the algae grows faster than the ecosystem can sustain leading to oxygen deprivation for the other aquatic organisms.</span>

Carbohydrates glycaemic index (GI)
Glycemic index estimates
carbohydrates containing food based on how they increase the glucose in the
body. Foods are rated by comparing them to a reference food. Foods with high glycaemic
index increases blood glucose than foods with average or low glyceamic index. When taking foods with high GI, low GI foods
should be combined with it in order to balance the meal. Examples of low GI
foods are corn, most fruits, and yam. Medium GI foods include pita bread and
whole wheat. Puffed rice, instant oatmeals are examples of foods with high GI.

Answer:
b. The rigid cell walls limit how far plant cells can expand and exert a back pressure to limit further water uptake.
Explanation:
Plant cells have a rigid cell wall made of cellulose. Animal cells lack a cell wall.
When the plant cells are placed in a hypotonic solution, water enters into the cells and the cells expand. However, after a certain limit, the cell wall exerts wall pressure on the contents of the cell and does not allow it to take more water in. The wall pressure from the cell wall of plant cells protects them against bursting when placed in a hypotonic solution.
Animal cells burst out due to intake of water by osmosis when placed in a hypotonic solution. They do not have a cell wall to protect them from bursting.
