What role do political parties play in elections?

You are working on a project that involves designing a very large dam. In order to obtain high confidence of the performance of the spillway, you decided to hire a local university to build a physical model of the dam spillway using a 1:25 scale model. According to the principles of similitude, the Froude numbers between the prototype and the model match. If the velocity at a specific point in the model is 6 m/s, what is the corresponding velocity at that point in the full-scale prototype (in SI units)?

There may be multiple correct answers. Please select all that apply.CIDR is:(a) an addressing scheme designed for multicast(b) a method to differentiate classes of service(c) a more efficient way to use the IP address space(d) incompatible with Ethernet(e) a method adopted in the Application layer

For the following acid-base reaction, predict the position of the equilibrium and identify the most acidic compound.  

What is the product of the following elimination?

Which of the following is the correct Newman projection for the following compound as viewed down the indicated bond in the conformation shown?  

In the citric acid cycle, citrate is formed with six carbon atoms: four from oxaloacetate (from the citric acid cycle) and two from acetyl CoA.  At the end of this cycle (just before citrate synthase), oxaloacetate is formed again.  Of the four carbon atoms in oxaloacetate, are from acetyl CoA and are from the original oxaloacetate atom.  The rest of the carbon atoms are transferred into .

What type of enzyme catalyzes the first step of the citric acid cycle (citrate synthase)?

The biochemistry lab class was given some trypsinogen that is synthesized in vitro using cell lysates containing all components necessary for transcription and translation. When they ran the enzyme activity assay, they found the enzyme does not exhibit any protease activity.  Why?

Consider the structure of ATP synthase:
