Chapter 45, Problem 7TYU
Summary Introduction
To analyze:
The change of runner’s oxygen consumption if runner wore shoes that prevented the arches from changing shape.
Introduction:
Locomotion in animals needs to be effective in a way so as to reduce the cost of energy spent. R. McNeill Alexander studied the cost-effectiveness of locomotion on human foot and discovered that the arch operates like a spring during running. Alexander proposed the hypothesis that there are large tendons in the lower legs of land animals. For example, the Achilles tendon at the back of your ankle works like a spring during running of animals.

Participants will be asked to create a meme regarding a topic relevant to the department of Geography, Geomatics, and Environmental Studies.
Prompt: Using an online art style of your choice, please make a meme related to the study of Geography, Environment, or Geomatics.
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?
What are some medical issues or health trends that may have a direct link to the idea of keeping fat out of diets?
