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 )

DRIs is the general term for a set of reference values or guidelines that are used to plan and asses nutrient intakes of healthy people. These values which vary by age and gender include:
- Recommended Dietary allowance (RDA): average daily level of intake sufficient to meet nutrient requirements of about 97 - 98% of healthy people.
-Adequate intake (AI): established when evidence is not sufficient to develop an RDA and is set at a level assumed to ensure nutritional adequacy.
- Tolerable Upper Intake (UL): Maximum daily intake unlikely to cause adverse health effects.
DRIs are not necessarily found on labels because there is no law requiring that they must be placed there.

An angiosperm is a group of plants that consists of herbs, shrubs and trees. The angiosperms bear flowers and fruit. Its' seeds are not naked as they are covered by the fruit wall.
</span>
All angiosperms produce flowers at some stage in their life. Flowers are important to the angiosperms because they serve as the reproductive organ for the plant, providing a means for the plant to propagate itself.
Angiosperms are the largest group of plants on earth. They account for approximately 80% of all known living plants. There are about 270,000 known species of angiosperms that live on the earth today.
