There are so many combinations of these four letters - A,T,G and C - that every combination creates a unique and distinctive characteristic. We can easily give example of alphabet and words. While English alphabet has 26 letters, there are thousands of possible words and millions of possible sentences, or maybe even more.
Answer:
transitional stage because it has high birth rate and low death rate probably due to war or domestic problems
Answer: Enzymes are proteins that catalyze, or affect the rate, of chemical reactions without themselves being altered in the process. Specific enzymes catalyze each cellular reaction. The main role of enzymes during the respiration reaction is to assist in transferring electrons from one molecule to another.
There are two types of inhibitors; competitive and noncompetitive inhibitors. Competitive inhibitors bind to the active site of the enzyme and prevent substrate from binding.

The Afrikaners are an example of a founder effect that occurs when population and the random decrease in genetic variation is an example of genetic drift.
Explanation:
When some individuals from a population move to form a new colony, this phenomenon is called founder effect as in case of Afrikaners. The small population or group of individuals forming a new colony may not exhibit the full genetic diversity of the population they were once the part.
The alleles would get expressed in different frequencies than it would have in original population.
There are chances that some alleles are lost or missing also. The new colony formed has small population so chances of genetic drift are very strong.
Genetic drift does not depend upon the benefit or harmful effect of the alleles as it occurs merely by chance sampling. The small population of Afrikaners felt the effect of genetic variation hence strong genetic drift is seen in them.
