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

faust18 [17]

I suppose it's matching?

Answer:

Catabolism: The conversion of nutrients into energy.
Enzyme: A large protein molecule responsible for facilitating biochemical reactions within the body.
Metabolism: The process by which a cell converts nutrients into energy or materials for growth, repair, reproduction, and maintenance.
Nutrition: The proper supply of nutrients essential for growth, reproduction, repair, immunity, and energy.
Anabolism: The process by which the cell uses nutrients to repair or build new tissues.
Nutrients: Chemical substances that are absorbed by the body through the process of digestion.
