It has been proposed that mitochondria and chloroplast are modern descents of early prokaryotic cell that begin to reside and gradually evolve within primitive cells. which statement supports this view? a. mitochondria and chloroplasts both have prokaryotic ribosomes. b. mitochondria and chloroplasts cannot conduct protein synthesis. c. prokaryotic cells, mitochondria, and chloroplasts are a void of any dna. d. mitochondria and chloroplasts are found in all modern prokaryotic cells.

The correct answer is option A, that is, mitochondria and chloroplasts both have prokaryotic ribosomes.  

Both the chloroplasts and mitochondria are the contemporary progenies of the initial prokaryotic cells. They have vested within the primitive cells, and then have developed with them as a component of them. The hypothesis is encouraged by the fact that both the chloroplasts and mitochondria comprise their own primitive ribosomes, that is, both these organelles exhibits 70s ribosomes.  

answer: glucoamylase presented optimum activity at temperature of 55â°c, and, in the glycosidic bonds from the non-reducing ends of starch, resulting in the production of glucose. source and type of fermentation can affect the enzyme's properties
