Units and significant figures Candidates should be aware that misuse of units and/or significant figures, i.e. failure to quote units where necessary, the inclusion of units in quantities defined as ratios or quoting answers to an inappropriate number of significant figures, is liable to be penalised.

Nov 09, · To investigate whether light intensity affects the rate of transpiration Answer. To investigate whether light intensity affects the rate of transpiration.

Hypothesis: The higher the light intensity, the higher the rate of transpiration. Variable-Manipulated variable: Light intensity. Effects of different anti microbials on bacterial growth.

Joseph Lister first introduced aseptic surgery in when he used a spray of carbolic acid (phenol C 6 H 5 OH) as a germicide. He was able to reduce mortality of post operative surgery by up to 45%. Factors controlling the rate of photosynthesis - detailed discussion of typical data graphs.

Graph 1. Light limitation. Light energy is needed for photosynthesis, so as the light intensity increases, the rate of photosynthesis chemical reactions steadily increases in a linear manner - 1st part of the graph is 'light .
