1A. (200 words or less) The article states “Both Monsanto’s
Vistive Gold soybeans and DuPont Pioneer’s Plenish soybeans are
engineered to silence the gene for an enzyme that converts oleic
fatty acid into linoleic acid.” These products were developed 10
years ago. Describe in conceptual detail :
1) how the gene silenced soybean was likely produced (100
words).
2) how the gene silenced...

IGNORE (i)
(ii) The procedure of finding series solutions to a homogeneous
linear second-order ODEs could be accurately described as the
“method of undetermined series coefficients”.
(iii) The underlying idea behind the method of undetermined
coefficients is a conjecture about the form of a particular
solution that is motivated by the right-hand side of the equation.
The method of undetermined coefficients is limited to second-order
linear ODEs with constant coefficients and the right-hand side of
the ODE cannot be an...

Draw two bar graphs, one
representing the ratio of saturated to unsaturated fatty acids
present in the cell membrane and the other representing the amount
of cholesterol present in the cell membrane. Each graph should
include a bar for each of the following groups of organisms. The
objective is to correctly represent what we would expect to see in
the cell membranes of organisms adapted to different temperatures.

Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...
