<u> Genetic bottle neck</u>
Explanation:
Genetic bottle neck is defined as an evolutionary event during which a population is drastically reduced to to a significantly smaller size within a short period of time.
A genetic bottleneck can result from various events such as natural disaster, hunting of a species to a point of extinction or habitat destruction to cause the death of large number of organism.
In the given situation a typhoon which is a type of natural disaster caused the population to reduce to a size of 20 individuals. Then we find that the allele frequencies were greatly changed and the allele for colorblindness became established.Hence, a large population of present day inhabitant are color blind.
So we can say that the population experienced a genetic bottle neck.
This membrane is called a selectively permeable membrane as it only allows for the entry of specific substances and does not allow of others.
Answer:
C.
Explanation:
An ecosystem is a place where living things live.
to make ATP, H+ ions will flow through the ATP synthase. this movement through ATP synthase will create enough energy for ATP to be formed.
