VashaNatasha [74]

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.

Why was the advent of the amniotic egg so important in the evolution of terrestrial vertebrates?
Fynjy0 [20]

Explanation:

The evolution of egg was the most important evolutionary incident which allowed the evolution of the terrestrial animals. The amnion is the layer inside the chorion of the egg which keeps the embryo from drying out.

The formation of this layer completely removed the dependency of the organism to lay their eggs in the water to keep them wet.

This layer allowed the reptiles to lay their eggs on the land as the amnion can protect the embryo from drying out. The other layer of eggs protects the egg from the predators and the pathogens.

Thus, the evolution of the amniotic egg is very important from the evolutionary perspective.
