2. Complete the following statements concerning smooth muscle characteristics by inserting the correct terms in the answer blanks. Endomysium 1. Whereas skeletal muscle exhibits elaborate connective tissue coverings, smooth muscle has a scant connective tissue_(1) smooth muscle 2. which is secreted by the_(2)_cells. The most common variety of smooth muscle, called_(3) smooth muscle, is arranged in unitary 3. opposing layers in the walls of hollow organs. Most often, there are (4)_ such layers, one running_(5)__and the other running (6) 4....
2) Draw and label a diagram of the carbon cycle. See Figure 4-3 for an example. Show the important reservoirs and indicate an approximate size (give units) of the reservoirs. Label arrows to depict the pathways that carbon takes through the various reservoirs (I don't expect you to list or memorize all the flux rates, but you should know which ones are important at different time scales). Then, below your diagram, list the carbon pathways that are most involved in...
3- (Bonus +15) There is a one-way narrow bridge on a public highway. Traffic may only cross the bridge in one direction at a time. The bridge can tolerate the weight of at most 5 vehicles. Each car which arrives the bridge calls the following OneVehicle thread: OneVehicle (Direction direc) { ArriveBridge(direc); CrossBridge(direc); ExitBridge(direc); In the code above, direc can be East or West which gives the direction of vehicle on the bridge. Using a Monitor, write the procedures ArriveBridge...

1. For the insertFirst method, create a diagram which shows how an existing list (you have to draw it) with 3 elements must be modified by this method. Label the modification steps in the order in which they must be coded. 2. For the removeFirst method, create a diagram which shows how an existing list (you have to draw it) with 3 elements must be modified by this method.

Question 23 & 24 36,4 A 4 [10123 The figure shows a cross section of a long solid cylindrical conductor whose radius is 25.3 mm. The conductor carries a uniform current of 36.4 A. Using Ampere's Law, determine the magnetic field at a distance of 7.04 mm from the center. Answer: Direction: (Magnitude) 9 [5124. Determine the net electric flux through the surface shown by the broken line at the right 4.-58, 4.-+65e - +50e, 4.-360, and q.44. Answer:

The diagram of the leg shows the femur (I) and tibia (2). The quadriceps muscle (3) applies a force to the lower leg via a tendon (4) that is embedded with the kneecap (5). If the force applied by the muscle to the tendon is Fm 500 N. what is the force of the femur on the kneecap, if the leg is in equilibrium? A simplified model of the leg is shown next to the diagram. The leg bones are...
