There are so many microbes in a single mL of culture, it is very difficult to perform one dilution to produce countable cells. M
icrobiologists need to perform a dilution series, where multiple dilutions are performed in sequence to arrive at the correct dilution. Dilutions are cumulative. Multiply the series of dilutions together to find the final dilution value. If 6 serial dilutions are performed, each with a dilution of 0.1, what is the cumulative dilution
A serial dilution is a stepwise kind of dilution repeated a certain number of times, in which the concentration reduces exponentially each time.
The cumulative dilution is the final dilution gotten depending on the number of times dilution has been done and the dilution factor. The formula is given as:
Explanation: It serves to produce lipids and steroid hormones, to rebuild plasma membranes, and to serve as a pathway for molecules to move along. These processes are essential to life for all eukaryotic cells.
The Sun, like others stars, is a ball of gas. In terms of the number of atoms, it is made of 91.0% hydrogen and 8.9% helium. By mass, the Sun is about 70.6% hydrogen and 27.4% helium.
