A trout exposed to acid mine drainage experiences an increase in mucus production along the gills. According to Fick’s law of diffusion, how would that affect the movement of oxygen through the gill capillaries?

1. Is this statement correct or incorrect? Explain.  During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right. This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 onto hemoglobin in the lungs. 2. Is this statement correct or incorrect? Explain.  Compared to hemoglobin, myoglobin has a lower binding affinity for O2 and a higher O2 binding capacity, two characteristics that allow myoglobin to efficiently provide skeletal muscle cells with a readily-accessible reservoir of O2.

1.What are the functions of the following structures? Nebulin: Troponin: Tropomyosin: Draw and label these components on the thin filament.What is the physical relationship between the 2 types of filaments?

Ventilators are often used for individuals with COVID-19 to increase the rate of diffusion of gases across the alveoli. Ventilators could increase the rate of diffusion by impacting which factor of Fick’s law of membrane diffusion: a   decreasing the diffusion coefficient (D) b   decreasing surface area (A) c   increasing the partial pressure difference (P1-P2) d   increasing the diffusion distance  e   all of the above
