You are planning to split a T25 flask of CHO cells that contained 5 ml of media. You removed all of the old media and washed the cells with PBS. The PBS was then removed and 1 ml of trypsin was added to disloge the cells. After 10 minutes, 4 ml of fresh media was added to the flask. 100 ul of cells were removed from the flask and added to 700 ul of fresh media in a microfuge tube. The tube was mixed and then 100 ul of cell suspension was removed and added to 100 ul of trypan blue. Using the countess you received a count of 4.5 x 10^4 cells/ml. What is actual concentration of cells in the T25 flask, after the trypsin and fresh media was added

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
