Question

BIOLOGY LAB QUESTIONS=- HELP ME

i converted the absorbance values into CELL CULTURE by multiplying each absorbance values by 1E10.

I need help with this. PLEASE SOLVE PART B. thanks. its says N= (log Nt- log No)/ log 2

b. How many generations of cells have been produced in Cuhure X and Culture Y within 120 minutes (1.25 points)? NOTE: # of generations in Culture A: N = (log N1 - log N0)/log 2 N = Number of generations in a given amount of tune log N0 = number of ccl Is at a early time point in the exponential phase log N1 = number of cells at a later time point in the # of generations in Culture B: exponential phase t = time in minutes between N0 and N1

Explanation / Answer

Based on the given data, culture X:

Time

Culture X

0

100000000

20

2.700000000

40

4.500000000

60

5.500000000

80

1000000000

120

2100000000

The doubling time is 27.3

Growth rate is 0.0253

Equation: amount=147940134.1348*e0.0224*time

At t=0, calculated cell concentration = 147940134.1348

For culture Y is:

Doubling Time: 21.37

Growth rate is 0.0324

Equation : amount=64638668771.589*e-0.0162*time

At t=0, calculated cell concentration = 64638668771.589
