Cumulative Problem 1
Marrrta [24]

Answer:

Volume, V=696.55\ \mu m^3

Explanation:

Given that,

The diameter of a human cell is 11 μm

It is enclosed by a membrane that is 4,4 nm thick.

We need to find the volume of the cell. The cell is spherical in shape. The volume of a sphere is given by the formula as follows :

V=\dfrac{4}{3}\pi r^3

r is the radius of the sphere, r = 5.5 μm

So,

V=\dfrac{4}{3}\times 3.14\times (5.5)^3\\\\V=696.55\ \mu m^3

So, the volume of the cell is 696.55\ \mu m^3.

Which best defines transparent and provides an example of a material that is transparent to light?
Crank
<span>Answer: option B. The ability to transmit light; for example water. The transparency is due to the pass of the light. The pass of light is what is called transmission of light. Light may be reflected, refracted or transmitted. Remember light is combination of several waves with different frequencies. When light falls upon an object the interaction may be some frequencies are reflected and other transmitted. Transparent objects are those that permit tha pass of (transmit) most light waves and so let the eyes and instruments to see through them.</span>
