The first reason was that his theory of continental drift was just too weak for most geologists to accept. Even though he believed the supercontinent that broke up into different continents moved, he did not have a clear explanation to how the continents moved. The other reason is that some of his explanation clashed with ideas that were widely accepted in the science communities. He used similar fossils from different continents to back up his theory of continental drift. However, at that time, many scientists that had observed similarities in fossils in places like South America and Africa believed there were similar fossils in different continents because of a land bridge that were formed by two continents.
Many science communities believe that land bridges allowed migration of many different species and even people to one place to another by large bodies of water frozen by low temperature known as ice age.
Answer:
Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. ... When humans burn fossil fuels, most of the carbon quickly enters the atmosphere as carbon dioxide. Carbon dioxide is a greenhouse gas and traps heat in the atmosphere.
Explanation:
Prokaryotes are defined by their lack of membrane bound organelles, so the reason prokaryotes don’t have them is that any cell that does have membrane-bound organelles would, by definition, not be called a prokaryote, because that is what humans have arbitrarily defined a prokaryote to be.
A more interesting question might be why cells with membrane-bound organelles evolved on earth, as far as we know, only once, among the eukaryotes, and why no other group among either the bacteria or the archaea, the two great prokaryotic groups who together make up over 2/3 of all life on earth, ever evolved membrane bound organelles.
That question takes us all the way back to the origin of eukaryotes themselves in an endosymbiotic merger between a bacteria and an archaean, and is a topic that would fill multiple books.
A very simplified answer is that, in order to support membrane-bound organelles a cell requires an active cytoskeleton and an internal membrane system, and supporting those two features requires a lot if energy, which eukaryotic cells produce using multiple mitochondria. Prokaryotic cells lack mitochondria and cannot produce energy at a fast enough rate to support such “expensive” adaptions.
