Briefly explain the progression of Duchenne muscular dystrophy.
An important component of blood is the buffer combination of bicarbonate ion and carbonic acid. Consider blood with a pH\mathrm{pH}pH of 7.427.427.42. a. What is the ratio of [H2CO3]\left[\mathrm{H}_2 \mathrm{CO}_3\right][H2CO3] to [HCO3−]\left[\mathrm{HCO}_3{ }^{-}\right][HCO3−]? b.What does the pH\mathrm{pH}pH become if 15%15 \%15% of the bicarbonate ions are converted to carbonic acid? c. What does the pH\mathrm{pH}pH become if 25%25 \%25% of the carbonic acid molecules are converted to bicarbonate ions?.
What is a rumen and how do the digestive processes operate in the ruminant digestive tract? What are the major benefits and disadvantages of a rumen system? How does a cecal animal compare with a ruminant? (Sections 22.6 and 22.7)
The three small spheres, each of mass m, are secured to the light rods to form a rigid unit supported in the vertical plane by the smooth circular surface. The force of constant magnitude P is applied perpendicular to one rod at its midpoint. If the unit starts from rest at θ\thetaθ = 0, determine (a) the minimum force PminP_{min}Pmin which will bring the unit to rest at θ\thetaθ = 60∘^\circ∘ and (b) the common velocity v of spheres 1 and 2 when θ\thetaθ = 60∘^\circ∘ if P = 2P min_{min}min.
