velocity= distance / time
your distance is 180 miles
your time is 3 hours
180 divided by 3 = 60
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.
While states have been relatively effective in stopping <u>The depletion of the ozone layer </u> they have been less successful at stopping <u>Global climate change.</u>
Countries all across the globe decided to stop using ozone-diminishing compounds in order to protect the ozone layer from depleting.
The Vienna Convention for the Protection of the Ozone Layer in 1985 and the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987 formalized this accord.
Ozone shields the Earth from the Sun's damaging ultraviolet (UV) radiation. Life on Earth would be extremely difficult without the Ozone layer in the atmosphere.
Plants and planktons, which provide sustenance for the majority of ocean life, cannot survive and thrive in high UV exposure.
