I believe that last one is true (photosynthesis of plants)

<span>The precision of scientific calculations is limited by the measurement that's the least precise out of all the measurements used in the calculation. When considering significant figures, the last answer should have the least significant figures out of all the measurements that entered into account and were able to be done with the most significant figures that could be directly measured. So, as more precise we are in measurements, more precise can be the final answer to a scientific calculation.</span>
There are so many examples for that in different areas, like TPBA experiment carried out in our lab recently.Here's one link: http://www.alfa-chemistry.com/tpba-cas-172285-72-2-item-294462.htm
False because they don't get anything from the farms
