The surface of a skeletal muscle cell is specialized for strength and to conduct action potentials.  This is why it technically called the ______, rather than just the “plasma membrane”.

The torque in a shaft rotating at 200 radians/second is 550 ft lbs.  What is the power delivery in horsepower?  Do not include units in your answer.

A student isolates, purifies, and combines in a test tube a variety of molecules needed for DNA replication. When she adds some DNA to the mixture, replication occurs, but each DNA molecule consists of a normal strand paired with numerous segments of DNA a few hundred nucleotides long. What has she probably left out of the mixture? 

These are the only immune cells that have access to the central nervous system. Type the best answer in the text box below:

This question requires uploaded work.  You will upload the work for this question after completing the test to the assignment in Canvas called “Test 3 Uploaded Work”.  TYPE YOUR FINAL ANSWER HERE using the equation editor if needed (it is accessed using the button that has a square root of x on it).  Your typed answer must match your uploaded work to receive credit for the question.   I’m working on decorating my island in the game Animal Crossing.  I want to create a rectangular enclosure that has an area of 13.5 square units by using  a flower border around the outside.  I also want to divide it in half with a  a line of flowers down the middle of the enclosure and parallel to one of the sides.  If the flowers are exactly one unit long and  cost 5 Bells (that is the unit for money in Animal Crossing), what is the minimum amount the flower border (including the line of flowers down the middle) will cost?

Given the free body diagram of the mated gears shown in Question 3, what is the actual direction of torque acting on gear B (TB)?

When sympathetic activity increases around the body, all arterioles and veins will constrict to help increase blood pressure.

Given the free body diagram of the mated gears shown in Question 3, what is the magnitude of the gear B torque (TB)? Pitch diameter of gear A is 2.0 inches and pitch diameter of gear B is 4.0 inches.  Provide your answer in units of lb in, but do not include units in your submittal.

Given the free body diagram of the mated gears, what is the resultant magnitude of the tooth force (Ftooth)?  Pitch diameter of gear A is 2.0 inches and pitch diameter of gear B is 4.0 inches.  Provide your answer in lbs, but do not include units in your answer.

When this general category of skeletal muscle contracts, it brings the centers of two bones closer together.
