yes
There is as much DNA in white blood cells as any other cell. There is none in red blood cells.
in any given mm3 of blood, what is the approximate ratio of the number of red blood cells (erythrocytes) to white blood cells (leukocytes)
carbohydrates
In 1cm3 of blood, there are 5,000,000,000 red blood cells and 8,000,000 white blood cells. Meaning a ratio of 5000 to 8.
Very, your brain could impload at any moment, you should probably get that checked..
Due to the limited field of vision of microscopes, it is comparatively easier to count the number of white blood cells in a stained blood smear under low power than under high magnification. Although the individual cells would be smaller and thus more difficult to count, there would be more in view at any given time.
Ther are equal numbers of red and white
White blood cells are the "army" of the circlulatory system-they guard against infection, fight parasites, and attack bacteria. Red blood cells only transport oxygen. White blood cells have more function. There are different kinds as well including phagocytes, allergy attacking cells, and a special class known as lymphocytes which prouce antibodies that are proteins that help destroy pathogens. I hope this helped a little.
Blood cells are predominantly red cells. They outnumber the white cells by a factor of 1000:1 to 2000:1 in normal humans. The composition of blood is 55% plasma and 45% formed elements. The formed elements are mostly red blood cells, which make up 44% of total blood volume. The remaining 1% consists of white blood cells and platelets. Appx. 700:1 Blood consists of formed elements (red blood cells, white blood cells and platelets) and plasma. Red blood cells (erythrocytes) account for 99.9% of cells. Plasma 55%, and Cells 45%.

They last your whole life (not true) red blood cells: die and are made evry 3 weeks white blood cell: you never get more than you have brain cells: you can get any more (if you inhale carbon dinoxid some of the brain cells die, so do do it!)
