Like DNA, RNA is made up of nucleotides. There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
after the evolution of the first living cells, fermentation wasn't needed, because aerobic respiration was now doable, since there was more oxygen in the air now. also, as the temperature increases, it becomes more energy consuming to conduct fermentation over aerobic respiration.
Hope this helps :)
The cytoplasmic streaming can be defined as the movement of the cytoplasm inside the cell. This movement of the cytoplasm helps in the delivery of the metabolites, organelles, and nutrients to all the parts of a cell. The cytoplasmic streaming, which is also known as cyclosis, occurs at the same rate throughout the cell and moves in the direction of the light.
Hence, the answer is 'moves at same rate and towards light'.
