The difference between PCR and real-time PCR is thatA. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot. B. real-time PCR can amplify DNA a billion-fold within just a few hours, while standard PCR cannot. C. real-time PCR can determine the DNA sequence, while standard PCR cannot. D. real-time PCR uses DNA polymerase, while standard PCR does not.

The correct answer is A. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.

Explanation:

PCR (Polymerase Chain Reaction) is a molecular biology technique. Conventional PCR and real-time PCR are diferent types of PCR, and are both used to exponentially amplify DNA molecules. In both types, a polimerase enzyme is employed to sinthesize DNA copies. The main difference is that conventional PCR is qualitative whereas real-time PCR is quantitative. So, real-time PCR permits not only to detect and amplify DNA but also permits to perform a quantification of the target DNA. This is accomplished by measuring a fluorescence signal - which is directly the amount of DNA amplified- during the course of the reaction.

b is the correct answer

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
