Q1. A farmer planted a field of BT 123 corn and wants to estimate the yield in terms of bushels per acre. He counts 35 ears in 1/1000 of an acre. He determines that each ear has about 500 kernels on average. He also knows that a bushel contains about 97,000 kernels on average. What is the farmer’s approximation of yield in bushels/acre?

Q2. In metabolic processes of cell respiration and photosynthesis, prosthetic groups as in heme and iron-sulfur complexes are encountered. What do they do?
