Speciation start to take place on a genetic level between two isolated populations by Allele frequencies change in different ways.
<h3><u>
Explanation:</u></h3>
The field of study called the population genetics helps us to understand about the composition of a selected population and the frequencies of alleles and how they get changed over a specific period of time. The mechanism called the adaptation mechanism ,mutation and gene flow determines the allele frequency changes in natural population.
Micro evolution refers to the changes in gene pool from one generation to another. Natural selection, mutation, genetic drift and gene flow are considered as the four forces of this evolution. When the allele frequencies starts to get changed in different ways, the Speciation starts to take place.
The answer would be D. Contain cytoplasm.
bacteria(prokaryotic cells) have a cell membrane, cytoplasm, DNA, ribosomes but lack all membrane bound organelles that eukaryotic cells have.
B. Unbalanced because temperatures are rising
Answer:
Clouds regulate the flow of radiant energy into and out of Earth's climate system
Explanation:
They are unicellular and not a multi-cellular, so your answer would be Option D)<span>They are multicellular.
Hope this helps!</span>
