<u>Answer</u>:
1. Type of medium - the nutrient availability is one of the vital factors for the growth of a bacterial colony. Thus, the used growth medium will fulfill this requirement.
2. Incubation temperature - all bacteria have an optimal temperature range in which maximum growth is achieved. Any variations from this will result in negative effects on the amount of bacteria that are produced.
3. Moisture - bacteria thrive in moist or wet environments. Thus, the availability of moisture is another vital factor for the growth of the colony.
60 percent of the biodiversity is in coral reefs
Answer:
between c. 95,000 and c. 20,000 years
Explanation:
I believe it is behavioural isolation. When there are changes within a certain species, e.g. new birdcalls are formed in certain individuals in a species, "traditional" birds may not like such mating calls and only choose to mate with the more common birdcalls from majority of the birds. There are also some birds that may like the new birdcalls, and choose to mate with birds with those birdcalls. They become genetically isolated as they continue such behavior. Eventually, through genetic drift and other mutations, different species form from a single specie.
Hope this helps! :)
