Answer:
Isolate DNA from all organisms and store at --20ºC.
Explanation:
The first step to be taken, in the case shown in the question above, is to isolate DNA from organisms, as molecular assays will need to be performed and these assays require the presence of the organism's DNA to be performed. Because DNA is a sensitive and unstable molecule, it must be preserved in a refrigerated environment to maintain its integrity and to be studied. Then, after isolating the DNA, technicians must store the DNA in refrigeration. It is best to store the DNA at -20ºC.
Answer:
1 / 10 ; 1 / 5 ; 5 / 12 ; 2 / 5
Explanation:
Experimental probability is defined as the ratio of the total number of times an event occur to the total number of trials.
In the experiment performed, the total number of trials is the number of times a paper was drawn from the lot, which 120 times.
From the experiment, the following observations were recorded :
X ___ number of times drawn
1 ____ 12
2 ____18
3 ____ 13
4 ____ 9
5 ____8
6 ____ 24
7 ____ 9
8 ___ 12
9 ___ 8
10 ___ 7
Experimental probability = number of times an event occur / total number of trials
Experimental probability of :
P(1) = 12 / 120 = 1 / 10
P(6) = 24 /120 = 1 / 5
P(an odd) = p(1) + p(3) + p(5) + p(7) + p(9)
P(odd) = (12 + 13 + 8 + 9 + 8) / 120 = 50 / 120 = 5 / 12
A prime number = P(2) + p(3) + p(5) + p(7)
P(prime number) = (18 + 13 + 8 + 9) / 120 = 48 / 120 = 2 / 5
1. You are wondering what my joke is about
2.you this read wrong
4.You just smiled because you have been fooled
5. You skipped number 3
6. You just checked if there was a number 3
7.you smiled again YOU HAVE BEEN FOOLED! :D
