Answer:
performing a controled experiment
Explanation:
this is because they can experience it themselcves, without having risk of external disturbance that would change tha outcome
<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
Answer:
Tt and tt
Explanation:
To solve this just work backwards. The first box has Tt so one parent has to have T and the other t. Since the tall plant is on the top, it is T_ and t_. Next use the second box (tt). They are both t so the final answer is Tt x tt.
Answer:
go for the second answer idk may be right i think
