Answer:
increasing extension time
Explanation:
The Polymerase Chain Reaction is a technique widely used in molecular biology laboratories to amplify target DNA regions. The standard steps of a PCR are as follow 1-denaturation, 2-annealing and 3-elongation/extension. These steps are repeated 15-40 times in order to exponentially amplify the linear DNA fragment. It is well known that longer extension times can be used as a strategy to increase the yield of longer PCR products. This is because the extension time depends on the synthesis rate of the DNA polymerase used in PCR technique and the length of the DNA fragment to be amplified.
Answer:
C. 50 drops/hr
Explanation:
As we can see in the description of the graph above, 50 drops/hr was the rate of water fall that was most successful in plant growth. This is because with this rate, the seeds germinated more quickly, the seedlings showed a strong and fast vegetative growth, besides that at the end of 5 days, it was observed that germination of almost 100% of the seeds occurred. These facts cannot be observed with the other waterfall rates, so the correct answer is 50 drops/hr.
Answer:Each of us has the power, through our own choices and actions, to save American lives and rescue the most vulnerable among us.
That’s why we really have to do what we all know is right. Every citizen is being called upon to make sacrifices. Every business is being asked to fulfill its patriotic duty. Every community is making fundamental changes to how we live, work, and interact each and every day, and I wouldn’t be surprised to see this going on long into the future, when this virus is gone and defeated. Some of the things we’re doing now will be very good practice for the future, including for not getting the flu, which is very devastating also. So some of what we’re learning now will live on into the future — I really believe that: shaking hands or not shaking hands; washing hands all the time; staying a little apart.
