Question
Chapter 18, Problem 2RQ
Summary Introduction
To review:
The effect of photosynthesis in the subsequent evolution of life on the earth.
Introduction:
After the origin of a living cell, some of them evolved to produce high energy complex molecule (glucose) from the simple molecule [water (H2O), carbon dioxide (CO2)] using sunlight. This process is known as photosynthesis, which gave rise to oxygen.

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?arrow_forwardIf four babies are born on a given day What is the chance all four will be girls? Use genetics lawsarrow_forward

What is the phenotype, and why is the phenotype so similar? Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?arrow_forwardWhat are some medical issues or health trends that may have a direct link to the idea of keeping fat out of diets?arrow_forward
