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.
Glycolysis takes place in "CYTOPLASM"
Answer:
i dont rlly get what ur asking but basically gasses diffues across the cell membrane from high conc to low concentration.
i dont know what passive transport is but active transport goes against the concentration gradient so im guessing passive is the opposite and goes with the conc gradient
Explanation:
Idk sorry lol lol lol lol
Answer:
5 bases
Explanation:
If there are 17 amino acids and only 2 bases that can be combined in order to make a codon then:
for 4 bases
is 16 and it is not enough combination for all 17 amino acids
for 5 bases
is 25 combinations (meaning that more than one codon could code for the same amino acid).
