Answer:
Stabilizing Variation.
Explanation:
This is the type of variation that occurs when genetic diversity decreases as the population of organism in a particular population based on a specific trait.
Organisms with varied or specific traits within the population are selected against by the selection pressure, with little chances of reproduction, while organisms in between, ( with least variation of this particular traits) which are within the narrow range, survive to reproduce.Thus, this gives rise to narrow population of these particular organisms,(stabilizing variation) which are therefore naturally selected.
Therefore, the variation of the organisms in this population is kept close to the centre of the same mean value.
Answer:
Most bacteria growth best within certain range of condition. By manipulating temperature and time, air, the proper amount of water acid and salt, you can eliminate, control, or reduce the rate at which bacteria grow.
Explanation:
Like all living things, bacteria need food, water and the proper environment to live and grow. The food product itself supplies the food and water needed for bacterial growth.he exact environmental requirements can vary from one type of bacteria to another. Most bacteria grow best within certain ranges of temperature, and have specific requirements related to their need for air, the proper amount of water, acid and salt. By controlling nutrients, water, temperature and time, air, acidity, and salt, you can eliminate, control, or reduce the rate at which bacteria grow.
Bacterias need following optimum conditions to grow
1. Food (nutrients)
2. Water (moisture)
3. Proper temperature
4. Time
5. Air, no air, minimal air
6. Proper acidity (pH)
7. Salt levels
By altering anyone of them we can restrict or reduce the rate at which the bacteria grow.
