bacteria culture starts with 400 bacteria and grows at a rate proportional to its size. After 4 hours, there are 9000 bacteria.
yawa3891 [41]

Answer:

A) P = P_0 e^{rt}

B) 19564

C) 5.5 or 6 hours

Explanation:

A) The formula that can be used for bacteria after "t" hours is

P = P_0 e^{rt}

Where ,

P represents the population after "t" hours

P_0 represents the initial population.

r represents the rate of growth of population

t represents the time taken by the population to grow

B) Here let us first find the rate of population growth.

9000 = 400 * e^{r*4}\\3.11 = r* 4\\r = 0.778

Thus, the population of bacteria after 5 hours

P = 400 * e^{0.778 * 5} \\P = 400* 48.91\\P =  19564\\

C)

30000 = 400 * e^{0.778 * t) \\\\4.317 = 0.778 * t\\t = 5.549\\or t= 5.5 or 6

How do i start making research for animal biology?
Luda [366]
From what I got to study the biology of animals you must:
1. Only pictures are not sufficient to know about the internal structures of animals. The anatomy describes about the internal morphology of the organisms.
2. So, for better understanding of the internal structures of animals, the student biology dissect the animals in the laboratory.
3. Dissection is an important practical for biology students.
Now this is what I got but it's somehow similar to this subject but, I hope this helped a bit.
