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.
Answer:
It is a tool for keeping population in equilibrium state.
Explanation:
One female egret represents that she is a tool for the continuity of its breed or species because female egret lays eggs and reared their offspring in order to maintain its generation in that salt marsh area. These female egrets are the essential part of this salt marsh ecosystem due to the ability to control the population of other organisms through feeding behaviour. These female egrets helps in maintaining the equilibrium of the ecosystem by constantly producing baby egrets.
Explanation:
The two main parts of a triglyceride lipid are glycerol and fatty acids.
Answer:
I would rather be a multicellular organism.
Explanation:
I say so because if I were to be a single cell organism, how would my life be? Would I still be able to think and move as I do as a multicellular organism? The answer would be no, I wouldnt. Single celled organisms like bacteria have a nucleus, unlike multicellular organisms. I would like to stay the way I am. (Just my opinion)
It can be classified in the phylum chordata.
Phylum : chordata
Sub-phylum: Vertebrata
Division: Gnathostomata
Superclass: pisces (respiration occurs typically by gills)
