Answer: Selective breeding
Explanation:
Selective breeding or artificial breeding is a process that allows humans to select parents in plants and animals that have desirable traits. Such parents are bred to produce offspring that have desirable traits from both parents. Humans have bred many species of plants and animals to improve the quality of plant and animal yields in terms of crops, milk, meat, eggs, and other derivatives.

Answer:
If the shape of an enzyme changes then the enzyme will no longer be able to perform its function.
Enzymes can be described as bio-catalysts which usually speed up a chemical reaction. Each enzyme has a particular substrate which fits into the active site of the enzyme. Every enzyme needs a particular temperature and pH for its functioning. If the shape of an enzyme changes, then it will no longer be able to perform its function and will become denatured.
Answer;
Food vacuoles that causes the yeast to turn blue indicates active digestive processes in the cell.The blue represents the mature food vacuoles as some yeast cells have now entered, and beginning the digestive process.
Explanation;
The ingested yeast cells appear red during early stages of being eaten. Later some of the yeast cells will enter into the food vacuoles to which acidosomes have fused, lowering the pH. The yeast cells within the food vacuole will turn blue, indicating active digestive processes in the cell. It is used for yeast uptake in the paramecium food vacuoles.
