It will cause vasodilation of blood vessels in the brain.
CO2 is one of the metabolic end products that can alter the
tone of the blood vessels in the brain. High CO2 levels cause vasodilation,
which may cause headache, whereas low CO2 levels cause vasoconstriction, which
may cause lightheadedness. The statements included in the other options are
incorrect effects.
Answer:
The correct answer is 4,960,000
Explanation:
If a yeast cell divides into two yeast cells in 120 minutes that means a yeast cell needs 2 hours to get double. So according to the question 2 hours ago a yeast colony consisted of 310,000 cells that means the present colony should have 620,000 cells.
So after six hours from now, this population will divide three times in six hours because the generation time of yeast cell is 2 hour and each time the number of cells will double.
Therefore, in first time the number will increase to 1,240,000(620000*2), the second time the number will increase to 2,480,000(1240000*2) and after final division, the number will be 4,960,000(2480000*2).
Therefore after 6 hours from now, the approximate number of yeast cells will be 4,960,000.
