(a)
To determine: The width of the A band if a muscle is contracted and shortened.
Concept introduction: Myofilaments within the myofibrils are organized in a continuous manner with cylindrical units called sarcomeres. Inside the skeletal muscle fibers, there are several repeating sarcomeres arranged within a section of myofibril. Overlapping of thick and thin filaments constitutes each sarcomere.
(b)
To determine: The width of the H zone if a muscle is contracted and shortened.
Concept introduction: Myofilaments within the myofibrils are organized in a continuous manner with cylindrical units called sarcomeres. Inside the skeletal muscle fibers, there are several repeating sarcomeres arranged within a section of myofibril. Overlapping of thick and thin filaments constitutes each sarcomere.
(c)
To determine: The relationship of the Z disks if a muscle is contracted and shortened.
Concept introduction: Myofilaments within the myofibrils are organized in a continuous manner with cylindrical units called sarcomeres. Inside the skeletal muscle fibers, there are several repeating sarcomeres arranged within a section of a myofibril. Overlapping of thick and thin filaments constitutes each sarcomere.
(d)
To determine: The width of the I band if a muscle is contracted.
Concept introduction: Myofilaments within the myofibrils are organized in a continuous manner with cylindrical units called sarcomeres. Inside the skeletal muscle fibers, there are several repeating sarcomeres arranged within a section of myofibril. Overlapping of thick and thin filaments constitutes each sarcomere.

- 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.arrow_forwardPlekhg5 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_forward

Your instructor will give you 2 amino acids during the activity session (video 2-7. A. First color all the polar and non-polar covalent bonds in the R groups of your 2 amino acids using the same colors as in #7. Do not color the bonds in the backbone of each amino acid. B. Next, color where all the hydrogen bonds, hydrophobic interactions and ionic bonds could occur in the R group of each amino acid. Use the same colors as in #7. Do not color the bonds in the backbone of each amino acid. C. Position the two amino acids on the page below in an orientation where the two R groups could bond together. Once you are satisfied, staple or tape the amino acids in place and label the bond that you formed between the two R groups. - Polar covalent Bond - Red - Non polar Covalent boND- yellow - Ionic BonD - PINK Hydrogen Bonn - Purple Hydrophobic interaction-green O=C-N H I.
