The bacteria have an initial concentration of 1000 cells/cm3 . Each cell divides once every 30 minutes. Calculate how long it wi
Levart [38]

It will take <u>120 minutes</u> for the concentration to become > 15000 cells/cm³

<u>Given data:</u>

Initial concentration ( density ) = 1000 cells / cm³

Target/final concentration = > 15,000 cells /cm³

<h3 /><h3>Calculating the concentration every 30 minutes </h3><h3 />

<em>note</em><em> : Given that each cell divides every 30 minutes </em>

  • <u>After the first 30 minutes </u>

Concentration = 2000 cells / cm³

  • <u>After 60 minutes </u>

concentration = 4000 cells / cm³

  • <u>After 90 minutes </u>

concentration = 8000 cells / cm³

  • <u>After 120 minutes </u>

concentration = 16000 cells / cm³

Therefore after 120 minutes the concentration of the cells will be greater than 15000 cells/cm³ ( i.e. 16000 cells/cm³ )

AnnyKZ [126]

Answer:

The correct answer would be - functions.

Explanation:

The structure of the skin cells and muscle cells are different and have a different number of cell organelles on their role in the body. Skin cells are a special type of cells that keep on shedding and replaced by new ones therefore they need less energy and have many mitochondria.

In contrast, muscle cells have different structures as they need a high amount of energy to make movements and therefore have lots of mitochondria in the cell.
