Answer:
The correct answers are 2.23 * 10^8 CFU/ml and 2 colonies.
Explanation:
Based on the given information, 0.1 ml is the amount of bacterial culture plated, 10^-5 is the dilution factor and the number of bacterial colonies produced is 223.
A) 223 is the number of colonies produced when 0.1 ml of the culture is plated. Therefore, the number of colonies produced when 1 milliliter of bacterial culture plated us (223/0.1)*1 = 2230
The calculation of the CFU/ml is done by using the formula,
CFU/ml = Number of colonies per ml plated / dilution factor
Thus, 2230/10^-5
= 2230 * 10^5 or 2.23 * 10^8 CFU/ml
B) The number of colonies, which would grow on a plate, which is inoculated with 0.1 ml volume of 10^-7 dilution from the similar bacterial stock will be calculated as,
CFU/ml = Number of colonies per ml plated/ dilution * volume plated.
2.23 * 10^8 CFU/ml = Number of colonies per ml plated / 10^-7 * 0.1
Number of colonies per ml plated = 2.23 * 10^8 * 0.1 / 10^7 = 2.23 or 2 colonies.
The answer of your question is

The answer: pilates
Pilates are a type of workout that are meant to increase flexibility, build strength, and promote body and mind control through a series of controlled movements. Some useful ways to increase resistance and to keep the body aligned during the exercise, is through equipment like springs and bungee
