Answer:
Ethanol is known as a fat solvent, and the cloudy or white color that it acquires when testing fat is due to the fact that this test includes the addition of water, forming an emulsion.
Explanation:
<u>The emulsion test for fats</u> is a test used to show the presence of these in some substances or foods.
Under normal conditions, fats are miscible - they can be dissolved - in ethanol, an alcohol, but not in water.
This test consists of dissolving the substance to be tested in ethanol, and then adding water. The principle by which the emulsion test is governed is that ethanol allows a certain amount of fat to dissolve in water, forming a cloudy or whitish emulsion.

Explanation:
An algal bloom has drained the lake of oxygen.
Explanation:
The possible cause of the fish death in the lake near the park is that an algal bloom has drained the lake of oxygen.
The green slime on top of the lake are the growing algae.
- This condition is caused by eutrophication.
- It occurs when nutrients are enriched in a water body causing the growth of algae.
- Algae bloom causes the depletion of oxygen levels in the ocean.
- They block off plants from producing oxygen and enriching water with it.
- Fishes need oxygen for their life actions.

Answer:
Hexokinase, Phosphofructokinase, Phosphoglycerate kinase and Pyruvate kinase
Explanation:
Coupled reactions are reactions that require energy by one process and is supplied by another; where the energy is transferred from one side of the reaction to the other.
In glycolysis, four (4) reactions undergo coupled reactions
1. Reaction one: which is the phosphorylation of glucose to glucose-6-phosphate coupled to the hydrolysis of ATP to ADP and Pi catalyzed by hexokinase.
2. Reaction three: The phosphorylation of fructose-6-phosphate to fructose-1-6-bisphosphate and the hydrolysis of ATP, catalyzed by phosphofructokinase
3. Reaction seven: Phosphoglycerate kinase catalyzes the conversion of Bisphoglycerate to 3-phoshoglycerate and the production of ATP from ADP
4. Reaction ten: Pyruvate kinase catalyzes the conversion of enol phosphate to the enolic form of pyruvate with the synthesis of ATP.
