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
concentration = 4000 cells / cm³
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 )

Shells are the exoskeletons of clams, snails and oysters. Hope that helps
Answer: c. maybe, depending on specific traits at organism in cellular levels of both animals
Explanation:
Evolutionary history has to do with the processes through which living organisms evolve from their ancestors to their present generations.
It's quite possible for the fruit fly and the fruit bat to share a common ancestor based on their evolutionary history depending on specific traits at the organism and cellular levels of both animals.
Therefore, the correct option is C.
Answer:
Soil erosion causes siltation in rivers, dams, etc. In some areas, huge river deltas are formed (such as River Nile delta) because of soil erosion. Such places are good for agriculture but not good for urbanization. However, some people do not care about it, they just want to construct buildings on alluvium type soils.
Answer:
Explanation:
Yes. They both have a cell membrane. They have many organelles that animal cells have and a cell membrane is one of the few similarities.
