I'm pretty sure 2 and 5 are right, but I'm not 100% on 1.
Have a nice day!
A list of non-pathogenic bacteria is an outline of the types of bacteria that do not cause illnesses in humans. They include:
staphylococcus
lactobacillus
Escherichia coli
bifidobacteria
bacteroides
Brevibacterium linens
In Short, it's A. Bacteria
<span> You need to use this formula to solve this exercise: P(t)=Ae^(k.t)
P(t) is the p</span><span>opulation of bacteria
A is the number of bacteria at the beginning of the experiment: 71
K is the growth rate
20 min= 1/3 hours
P(0)=71
P(1/3)= 71 ⇔ P= 71 x 2 ⇔142
142= 71 x e^k/3
2= </span><span>e^k/3
ln 2 = k/3
3ln 2=k
ln(2³)=k
</span>k=ln8
D is what I would put because it looks right
