Summary Introduction

To analyze:

Whether switching from phase 1 to phase 2, that is, nonorganic to organic, lowers the amount of pesticides secreted in the urine of the children or not in the following experiment.

Levels of metabolites (breakdown products) of malathion and chlorpyrifos in the urine of children taking part in a study of effects of an organic diet:

Malathion metabolite Chlorpyrifos metabolite
Study phase No. of samples Mean (µg/L) Maximum (µg/L) Mean (µg/L) Maximum (µg/L)
Nonorganic 87 2.9 96.5 7.2 31.1
Organic 116 0.3 7.4 1.7 17.1
Nonorganic 156 4.4 263.1 5.8 25.3

Introduction:

Organic foods are produced using methods that meet the standards of the organic farming. The organic food tends to limit the accumulation of the toxic compounds, which one might be consuming along with the nonorganic food substances.

"One of the symmetry breaking events in mouse gastrulation requires the amplification of Nodal on the side of the embryo opposite to the Anterior Visceral Endoderm (AVE). Describe one way by which Nodal gets amplified in this region." My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE.  1. pronodal cleaved by protease -> active nodal 2. Nodal -> BMP4 -> Wnt-> nodal 3. Nodal-> Nodal, Fox1 binding site  4. BMP4 on outside-> nodal  Are all of these occuring opposite to AVE?
