Answer:
Ratio = 
Explanation:
Side of a cube, a = 20 µm
The surface area of a cube, A = 6a² (a is side of the cube)
The volume of a cube, V = a³
The ratio of the surface to volume ratio of the cell will be given by :
So, the ratio of the surface to volume ratio of the cell .
Answer:
The researchers were unable to grow the microbe in the laboratory BECAUSE THE PREVAILING ROOM TEMPERATURE IN THE LABORATORY IS UNSUITABLE FOR THE GROWTH OF THE MICROBE.
Explanation:
Microbes that grow near deep sea thermal vent usually have the ability to exist in environment that have abnormally high temperatures. In order for a researcher to grow such microbes in the laboratory, he must be able to reproduce the high temperature that is found in the natural habitat of the micro organisms. Growing the microbes in the laboratory at room temperature will be unsuccessful because the microbes can not survive at that temperature.
