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:
A nerve is actually a long threadlike bundle of dendrites that conduct electrical impulses. Dendrite word derived from the Greek word 'dendron' which means tree. They carry messages in the form of electrical impulses to cell body, there are also wire like nerves called axon.

Answer:
A mountain chain of sedimentary rock may form as a result of a convergent boundary of two continental crusts
Explanation:
B - They both use protein channels (I think so at least) they differ because active transports use a pump to leave the cell and it uses atp (cell energy).
