Answer:

d . a and b are correct

Explanation:

The law of superposition allows us to determine the age of rock layers and also that of the fossils within them.

The law of superposition states that "in an undeformed sequence of strata, the oldest rock layer is at the bottom and the youngest is on top".

Using this law, geochronologists can determine the relative ages of rock layers.
The youngest layer will be found on top.
The oldest at the bottom of the sequence.
The arrangement of the layers and the fossils there in can also tell us about the ages of the fossils themselves.

Explanation:

In space, there is only vacuum hence no any medium for sound wave travel.

Since sound waves are mechanical waves, they require a material medium such as air, hence no sound transmission.

If a concentration of 10 fluorescent molecules per μm2of cell membrane is needed to visualize a cell under the microscope, how m

lara [203]

Answer : Total molecules that will be needed to visualize a single egg will be 78500 molecules of dye.

Explanation : As a single egg cell has an approximately diameter of 100 μm.

We can use this formula to calculate area of the cell membrane;

A = π $(100)^{2} / 4$ ;

We can take π as 3.14 and we get;

A = 3.14 X $(100)^{2} / 4$

Soving we get;

A = 7850 μ $m^{2}$

Here we have to calculate the amount of dye molecules which will be needed for 10 fluorescent molecules / μ $m^{2}$ but;

here 1 μ $m^{2}$ = 7850 μ $m^{2}$ dye molecules.

Therefore, 10 fluorescent molecules will need;

7850 X 10 = 78500 molecules of dye.

Therefore, the answer is 78500 molecules of dye.
