nikitadnepr [17]
<h3>Your answer is D.</h3>

The insects are the same species.

<h3>Explanation:</h3>

A species is a group of similar organisms able to reproduce (to exchange genes and interbreed) only within the group. That means that organisms from different species could not exchange genes. Since mentioned insect groups are able to reproduce and produce offspring that could also breed, these groups belong to the same species. If they could not reproduce and produce offspring that could also breed, these groups would belong to the different species.

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
