How much DNA does a human share with a potato?
Humans share very little with a potato. Chromosomes are a collection of DNA woven around protein. A chromosome may contain as many as 100,000 to billions of nucleotides in one chain. Chimpanzee and humans share a very SIMILAR DNA pattern, where as a potato and a human being don't. So although they both have 48 chromosomes, their DNA STUCTURE is vastly different.
Does a human female carry two Barr bodies?
Sex in humans is determined by the combination of sex chromosomes, X and Y. In males, every cell in their body (except for erythrocytes (red blood cells, which are non-nucleated and do not contain DNA)) and sperm cells (which only contain either a single X or Y chromosome) contains both X and Y chromosomes. In females, every cell (except those previously mentioned in males) contains two X chromosomes, except that one of those (through a process believed to be random) X chromosomes atrophies into what is called a "Barr body". Basically, this is a transcriptionally inactive chromosome (in that there is no gene expression from this chromosome). Only 1 of the 2 X chromosomes in each cell undergoes this. Your question is worded strangely because it sounds like you're asking if the ENTIRE female body contains 2 Barr bodies, when in fact it contains billions and billions of bar bodies...however, I suspect you were asking on the cellular level, and thus every somatic (non-sex) cell in the female body contains a single Barr body and a single functional X chromosome.* *There are genetic anomalies that may be the exception to this, but this is in normal, healthy females.
What was the primary factor missing for billions of years that was necessary for protists to evolve?
The primary factor that was missing for billions of years that was necessary for protists to evolve was oxygen in the atmosphere. Billions of years ago, the atmosphere was mostly made up of carbon dioxide, carbon monoxide, hydrogen, nitrogen, and water vapor.

Why they have identical chromosomes?
Since we all come from a single cell that's multiplied billions pf times to make us - each cell is an exact copy of itself - therefore the chromosomes are identical.

How many DNA molecules are in a chromosomes?
There is one double helix DNA molecule per chromosome.
How many chromosomes exist in your body?
A normal human cell contains 23 pairs of chromosomes, for a total of 46. If you had an average of 40 trillion cells in your body that had 412 chromosomes you would have 4456 trillion chromosomes in your body. Note that some mature cells in your body do not have any chromosomes, some have 26 chromosomes and some cells have 99 chromosomes.
Why do they have identical chromosome?
Since we all come from a single cell that's multiplied billions pf times to make us - each cell is an exact copy of itself - therefore the chromosomes are identical.
