A researcher collects data on plant species composition in two habitats (P and Q) by using 10 quadrats each in both habitats. She calculates the average a-diversity and the 13-diversity of each habitat from this data (shown below). Which of the following can be inferred about these habitats? 

A) Q has greater total diversity (γ) and more heterogeneous than P

B) Q has lower total diversity (γ) and less heterogeneous than P

C) P has lower total diversity (γ) and more heterogeneous than Q

D) P has greater total diversity (γ) and more heterogeneous than Q

Precision will be reduced, but yield will be increased

Optimisation of a PCR reaction is often a compromise between the competing demands for precision, efficiency and yield. Although the specific effects may vary, generally, increasing the annealing temperature will increase non-specific primer binding and reduce precision. Increasing the length of the elongation phase will reduce the proportion of incomplete newly-synthesised strands and therefore increase yield. In this case, the potential effect on efficiency is unclear. Increasing the elongation phase would increase the reaction time, but the time taken to ramp down to a lower annealing temperature would be reduced.

Which of the following true about real time PCR?
