Which of the following is not a piece of molecular evidence supporting the endosymbiotic theory? .a. some organelles divide by fission just like bacteria.
b. the mitochondria and chloroplasts are much different in structure than bacteria.
c. mitochondrial and chloroplast dna is similar to bacterial dna.
d. ribosomes of some organelles are like that of those found in bacteria.

The best answer is B. The endosymbiotic theory states that mitochondria and chloroplasts have striking similarities to bacterial cells: 1. they have their own DNA, which is separate from the DNA found in the nucleus of the cell. 2. Both organelles use their DNA for to produce many proteins and enzymes required for function. 3. They are both surrounded by a double membrane. 4. They reproduce just the way bacteria do, replicating their own DNA and directing their own division.

Glucose, also called grape sugar, blood sugar or corn sugar, is among the simplest and one of the primary naturally occurring sugars. produced naturally by plants as the primary photosynthesis product, it is heavily used by living beings as a main energy source and is necessary for cellular respiration. chemically, it is a monosaccharide carbohydrate and serves as a building block for complex sugars like starch.
