because of the smoke, the light colored moths were easily spotted and eaten. but they changed color over time to account for that, turning black to make them harder to spot and eat.
Answer:
a.Many mitochondrial genes resemble proteobacteria genes, while the genes in the chloroplast resemble genes found in some photosynthetic bacteria.
c.Mitochondria and chloroplasts both have their own circular DNA and 70S ribosomes that are similar to those found in bacteria.
d.Mitochondria and chloroplasts replicate by a process similar to mitosis.
Explanation:
Endosymbiotic theory states that mitochondria and chloroplast which are organelles of eukaryotic cells were once independently living micro-organisms but with due course of time eukaryotic cells engulfed them and they become an integral part of these eukaryotic cells.
The resemblance between mitochondrial genes with those of proteobacteria and chloroplast genes with photosynthetic bacteria strongly support endosymbiotic theory. Apart from this, the presence of their own DNA that too circular just like prokaryotic microbes and 70 S ribosomes also support this theory. Also just like prokaryotic cells, before cell division mitochondria and chloroplasts undergo replication by means of a process known as binary fission.
E Coli bacterium are about 2.0 micrometers in length and .25 to 1 micrometer in diameter. In comparison, a red blood cell is about 6 to 8 micrometers in diameter and a thickness that ranges from .8 to 1 micrometer in the center to 2 to 2.5 micrometers at the thickest point.
