To determine: The different ways by which an athlete could boost oxygen-delivering capacity and whether all methods shall be considered as ‘cheating’ and be banned.
Introduction: The cardiorespiratory system in the body plays an important role in delivering oxygen to muscles. Red blood corpuscles present in the blood contains a protein containing pigment that is hemoglobin. The hemoglobin has the capacity to carry oxygen and carbon dioxide. The hemoglobin carries oxygen to tissues and cells for oxidative phosphorylation at the end of which ATP is produced. The ATP produced in muscles will aid the athletes to make better use of their muscles in the sport they are competing in.
To determine: The appropriate punishment for an athlete who is caught blood doping.

- "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?arrow_forwardIf four babies are born on a given day What is the chance all four will be girls?

- Plekhg5 functions in bottle cell formation, and Shroom3 functions in neural plate closure, yet the phenotype of injecting mRNA of each into the animal pole of a fertilized egg is very similar. 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_forwardwhat did charles darwin do in sciencearrow_forward
