The correct answer is b. the combination of modern genetics and Darwinism.
Explanation:
Modern synthesis is the experimental and theoretical work that was made by combining the work of two scientist Charles darwin and George Mendel. This term was coined in a book called Evolution: The Modern Synthesis.
New definition of evolution was proposed by it which was focused on the genetic basis of evolution for example allele frequency changes in the population. Gene flow, mutation pressure, natural selection, and random genetic drift were taken as the cause of evolution. So the correct answer is b.
B. the combination of modern genetics and Darwinism.
Explanation:
The modern synthesis refers to the concept which combined the theory of inheritance by Mendel and theory of evolution by Charles Darwin. The theory also used the concept of Theory of germplasm.
The modern synthesis concept came in the early 20th century when the studies were going on Mendel's theory and the evolutionary aspects. The concept led to the formation of new concepts like the macroevolution, microevolution and the evolution affected by mutation of genes.
These areas have anoxic condition means they have very little to zero dissolved oxygen hence cannot support marine/aquatic life. This is as a result of eutrophication caused by algae blooms. This phenomenon is brought about by pollution of these water reservoirs. These algae bloom take up all the oxygen in the water during their mass decomposgion hence leave no dissolved oxygen for the rest of the marine life.
This type of classification used to be used when classifying the protostome organisms. In this type of organism, the oral cavity develops from the blastophore, the initial cavity in the gastrula, an early stage of the development of the embryo.
