Hello! Your answer is the bottleneck effect.
Speaking more broadly, genetic drift is when a population becomes smaller, and there are fewer genotypes in the gene pool. There are two types of genetic drift: the bottleneck effect and the founder effect.
The bottleneck effect is when an environmental change / human activity causes many members of the population to die, which means that the gene pool is now represented by just a few organisms. This is correct in this scenario, as an environmental change caused the gene pool to be reduced.
The founder effect is when a new colony is established elsewhere, so only alleles in the smaller founder group will be reproduced.
Hope this helps!
I don’t really understand the question but i’m assuming that’s there’s a chemical reaction happening when the bicyclist is eating the food to get energy to bike?
Microscopes
Before the development of microscopes, the existence of cellular life was unknown. By examining a piece of cork, Robert Hooke first saw and named cells. Antony van Leeuwenhoek was the first person to see living cells.
All eukaryotic cells have membrane covered compartment called organelles. They include the nucleus, the Golgi, mitochondria, endoplasmic reticulum and many others. So the answer is- organelles. ;)
A certain gene is only used for certain functions, and if that gene is always going, your body cant turn certain functions on and off, which can ultimately lead to a lot of health problems.
