Answer:Even in a simple flower, a great variety of diverse forms occur in nature. When flowers are arranged linearly on a stem, each flower can have a stem or they can each be stemless. If they are stemless, the flowers are said to be sessile, and the whole structure, or inflorescence, is called a spike. So yes it has a complex stucture
Explanation:
a green coloration since grass is green
Answer:
The correct answer is <em>A. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.</em>
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.
