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.
The answer to this question is Autotrophic.

Answer:
The North produced 17 times more cotton and woolen textiles than the South, 30 times more leather goods, 20 times more pig iron, and 32 times more firearms. The North produced 3,200 firearms to every 100 produced in the South.

Answer:
7
Explanation:
The number of distinct shades of fruit color would be 7. It is given that the color is dominated by a group of three QTL(quantitative traits) with each trait having two alleles(A,a). Out of these two alleles, one represented by a capital letter(A) generates a single dose of yellow pigment while the latter represented by a smaller case letter(a) does not generate any pigment. Since <u>there is no environmental effect, the number of various yellow shades would be 7 through the combinations of yellow and colorless pigments(A/a, A/a, A/a, A)</u>.
