1. Question:You have been growing the same variety of corn for over 5 years. In the past two years, you have noticed that the yield has decreased by 10% each year. You grow corn on 10 acres of land and your yield should be 1000 bushels per acre. Growing conditions have been consistent for the past 5 years. You want to identify another variety of corn that will produce 1,000 bushels per acre. You currently grow Variety ZQB. You want to test two new varieties, CAQ and TWX. You hypothesize that an...

Initial Post Instructions Option 1: Your initial post in the discussion this week consists of two parts. First, choose amolecule used in healthcare, industry, or found in a natural source and discuss theimportance of this molecule. Be sure to include at least one outside source and makesure to follow APA citation guidelines.
