The endosymbiont theory explains the origin of the eukaryotic cell organelles where the cells were engulfed but not digested by the larger prokaryotic cells and in the process developed into the chloroplast, mitochondria and other organelles.
(A) The theory was trying to explain the evolutionary origin of the various cell organelles and,
also explains the dependence of cells on one another.
(B) The evidences that supported the Endosymbiotic theory includes;
-The photosynthetic bacteria; This bacteria utilize the sun's energy to make energy hence the oxygen released from the process accumulated in the atmosphere thereby leading to the death of the anaerobic cells.
-Organelles have their own DNA and divide independently, therefore Margulis predicted that if the organelles were really prokaryotic symbionts, then they would have their own DNA.
- The study of fossils showed the aerobic cells in it, therefore the cells could use the toxic oxygen and convert it into ATP(energy) and water. Organisms that could thrive in aerobic environments were now best suited to the environment.
Answer:
The Answer is Small Intestine
Explanation:
A small intestine is attached to the stomach and goes all the way to the anus. Despite it's name it is not really small. It was average size. 20 feet long and about one inch thick in diameter. However, the size can greatly vary in some people from as small as 10 feet to as large as 34 feet.
As our food passes through the small intestine, small fibers start to absorb as much nutrients and minerals it can from the food.
Along with humans it is found in every four-limbed animal and is particular large in herbivors.
That the birds are named after the color of there feathers
The chloroplasts carry out photosynthesis
