WebIn this GCSE Biology quiz we look at the effects of anomalous results, how to go about identifying them and what action we can take when we have found them. Anomalous results are odd results - those which are not in keeping with the rest of the results or which do not follow any correlation you have spotted. If you have repeated your experiment ... WebMar 6, 2024 · Ultimately, the higher the light intensity the less time it takes for the indicator to turn purple. This is because light effects the rate of photosynthesis. Therefore, the more light, the faster the pondweed will photosynthesis. The change in carbon dioxide (due to pondweed photosynthesising) dissolved in the water effects the acidity of the ...
