Suppose the cells of a tumor are idealized as spheres each with a radius of 5 mum (micrometers). The number of cells has a doub

loris [4]

Answer:

1044.3 days

Explanation:

Given,

Radius of sphere shaped cells of tumor $= 5$ micrometer

$1$ centimeter $= 10,000$ micrometers

Thus, radius of sphere in centimeters

$= \frac{5}{10,000} \\$

Volume of a sphere

$= \frac{4}{3} \pi r^{3}$

Volume of one cell of tumor

$\frac{4}{3} *(3.14)*(\frac{5}{10,000})^{3}\\= {5.23 * 10^{-10}$ centimeter cube

As we know ,

$N(t) = N(0) e^{-kt}\\\\k = \frac{ln2}{35}\\ k = 0.0198 day^{-1}\\$

Substituting all the given values in above equation, we get -

$0.2 = 5.23 * 10^{-10} * e^{-0.0198*t}\\t = 1044.3$ days

<h2>Active Transport</h2>

Explanation:

Active transport is the development of a wide range of atoms over a cell layer against its concentration gradient.

In all cells, this is typically worried about collecting high molecule concentration that the cell needs, for example, glucose,amino acids, ions.

On the off chance that the procedure utilizes chemical energy For example, from adenosine triphosphate, it is named Primary active transport. Secondary active transport includes the utilization of an electrochemical grtadient.

Active transport utilizes cell energy in contrast to uninvolved vehicle, which doesn't utilize cell vitality. Example of active transport includes take-up of glucose for the digestive organs in people and the take-up of mineral particles into root hair cells of plants.
