River Pascal with a volume flow rate of 3.3×105 joins with River Archimedes, which carries 1.09×106 , to form the Bernoulli River. The Bernoulli River is 120 wide and 20 deep.
A student runs an enzyme assay using the anaerobic glycolytic enzyme, lactate dehydrogenase (LDH). Their 1 ml assay is: 900 μl 200 mM Tris, pH 7.335 μl 30 mM pyruvate (in H2O)35 μl 6.6 mM NADH (in H2O) 30 μl of their LDH solution, in 200 mM Tris, pH 7.3They mix everything gently together in a cuvette and then measure the ΔA340/Δtime using a spectrophotometer. Their measured ΔA340/30 sec. was “-0.0311”.question : d) Let’s say that the total time of your LDH assay was 2 minutes. Did the pH of the assay change much during that time? Show a calculation. (Model your calculation after questions #40 and #41 on page 93 of Biochemical Calculations). The pKaof Tris is 8.21. No, the pH remained at 7.3. Use two HendersonHasselbalch equations.
Mass of Earth=5.97 x 10 ^ 24 KG Mas of Moon=0.073 x 10 ^ 24 KG.
It comes tha t mass of Moon is 1.2 % of only. .073 divide by 5.97 x 100= 1.2%.

You must provide examples for your explanation.
In the Olympics and other major athletic competitions, a GC-MS is used to screen athletes for their use of banned substances such as steroids. If an analytical method has been developed and the retention time for a particular anabolic steroid has been determined, how might you use this method to determine the possibility of the use of anabolic steroids by an athlete?
Research the functions, importance, and role of fat- and water-soluble vitamins.

Explain the difference between changes in internal energy, delta E (also called delta U), and changes in enthalpy, delta H?
A wave traveling along the x axis is described mathematically by the equation y = 0.17sin(3.1πt + 0.55πx), where y is the displacement (in meters), t is in seconds, and x is in meters. What is the speed of the wave?
d) What is the magnitude of the tension in the cable supporting the package? Carefully show all steps in your work.A helicopter flies to the right (in the +x direction) at a constant speed of 12 m/s, parallel to the surface of the ocean. A 1350 kg package of supplies is suspended below the helicopter by a cable as shown in the figure: the package is also traveling to the right in a straight line, at a constant speed of 12 m/s.
