If a concentration of 10 fluorescent molecules per μm2of cell membrane is needed to visualize a cell under the microscope, how many molecules of dye would be needed to visualize a single egg? enter your answer in scientific notation rounded to two significant figures.

Answer : 78500 molecules of dye would be needed to visualize a single egg.

Explanation : An single egg cell has an diameter of 100 μm which is an approximate value.

To calculate the area of the cell membrane we can use this formula.

A = π ;

Therefore, A = 3.14 X

So, A =  7850 μ

Now. to calculate the amount of dye molecules needed for 10 fluorescent molecules / μ

will be;

as 1 μ = 7850 μ dye molecules.

Then 10 fluorescent molecules will need;

7850 X 10 = 78500 molecules of dye.

Therefore, the answer is 78500 molecules of dye.

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
