Explain how the movement of NaCl and water in the ascending and
descending limbs of the loop of Henle work as a countercurrent
system. Use a diagram to help explain this.

A descending grade of 4.2% intersects an ascending grade of 3%
at sta. 12+325 at elevation 14.2 m. These two grades are to be
connected by a 260 m vertical parabolic curve. A reinforced
concrete culvert pipe is to be constructed with its top 30 cm below
the subgrade (or the lowest point of the curve)
What will be the invert elevation of the culvert?
An ascending grade of
4% and a descending grade of 2% intersect at STA 12+598 whose
elevation is at 518.99m. The two grades are to be connected by a
parabolic curve, 160 long. Find the elevation of the first quarter
point on the tangent and the summit of the curve.
a.)Determine the
elevation of the summit.
b.)Determine the
station of the summit.
c.)Determine the
elevation of the first quarter point on the tangent.
d.)Determine the
elevation of the midpoint on...
2. Explain how the directional movement of phosphates from ATP
to water can be used to turn on and off proteins, power active
transport, and power the directional movement of “walking
proteins”. In what way is the powering of walking proteins
distinctly different than the other two?
Describe how you would prepare 2 mL of solution containing NaCl,
MES buffer, and water. NaCl stock solution is 1M and the working
concentration required is 5mM. MES buffer stock solution is 100 M
and the working concentrations required is 20 mM. To make 2 mL of
solution calcualte the amount of water you would add.
