Answer:
0.1 degree per annum
Explanation:
There are 30 years between the years 2020 and 2050. If the average temperatures increase by 3 degrees Fahrenheit in 30 years, then the rate of change of temperature equals the ratio of the total increase in temperature and the number of years.
Rate of change = 3/30 = 0.1
<em>Hence, the rate of temperature change is </em><em>0.1 degree Fahrenheit </em><em>annually.</em>
Answe: The cells in flask B will have grown significantly, but the cells in flask A will have not grown at all.
Explanation:
Conditions for the growth of mammalian cells and non animal Cells are different.
For bacteria cells, shaking will be required which allows oxygen to freely enter the cells and provide more nutrients to promote growth. However, this is not the same for animal cells.
When culturing mammalian cells, a CO2 incubator running at 37° C is required as opposed to non-mammalian cells that can be grown in a non-CO2 or dry incubator.
