USE PYTHON TO SOLVE THIS PROBLEM
A bacteria culture grows exponentially. After 2 hours, the
bacteria count was 400 cells and after 6 hours, the bacteria count
was 20,000 cells.
a) Solve a system of equations to find (approximately) k and y0
(HINT: If will help to assume K is real in the symbols command)
b) Use this to determine when the bacteria count reaches
2,000,000 (exact and approximate).
c) Suppose 400 was the “initial” amount and 20,000 the count...

USE PYTHON TO SOLVE THIS PROBLEM
A bacteria culture grows exponentially. After 2 hours, the
bacteria count was 400 cells and after 6 hours, the bacteria count
was 10,000 cells.
a) Solve a system of equations to find (approximately) k and y0
(HINT: If will help to assume K is real in the symbols command)
b) Use this to determine when the bacteria count reaches
1,000,000 (exact and approximate).

1. There are 300 bacteria in a culture, and the number of
bacteria quadruples every 5 hours.
A. Write a function, N, that gives the number of bacteria t
hours from now.
B. How many will there be in 20 hours?
C. In how many hours will there be 2,000 bacteria?
2. The population of Johnsonville was 900 in 1880 and is known

1. how is gram stain done?
2. What types of bacteria are stained differently in the Gram
stain?
3. What is the key step in the Gram stain that distinguishes
between two different cell types? Explain why.
The laboratory reported gram-negative bacteria arranged inside the
leukocytes of the pus sample. Other tests confirmed the pathogen
was Neisseria gonorrhoeae, indicating Tom had the sexually
transmitted infection gonorrhea.
4. Describe the shape of the gram-negative bacteria shown in the
photo.

(1 point) A bacteria culture starts with 560 bacteria and grows
at a rate proportional to its size. After 3 hours there will be
1680 bacteria.
(a) Express the population after t hours as a function of t
population: (function of t)
(b) What will be the population after 2 hours?
(c) How long will it take for the population to reach 1250
?

Pre-Lab Questions:
What color will endospore negative bacteria be after endospore
staining? What color will mycobacteria bacteria after mycolic acid
staining? (see the endospore and acid fast tables)
What species of bacteria are we going to use to look at
endospores and what species will we use for mycolic acid
staining?
Why do we briefly heat our bacteria on the slide before
staining?
Acid-fast endospore staining

USE R AND SHOW CODES!!
1.a. There is a theorem that the ratios of blood types O, A, B
and AB are 49:38:9:4,
respectively. A research team, investigating a small community
and obtained the following frequencies of blood type.
Blood type
Blood Type O A B AB
Frequency 87 59 20 4
Test the hypothesis that the proportions in this community do
not differ significantly
from those in the general theorem.

Salmonella bacteria can cause two different types of disease.
What is the disease called that is accolated with ingestion of
salmonella from water of food, and where he results often a
systemic infection? Describe methods that can clarify weather
salmonella isolates from a given food suspected of being a source
of outbreak are identical to salmonella from patients who have
become ill as a consequence of the outbreak
