If function A calls function B, and function B calls function C, and function C calls function D, when function D finishes, what happens?

String indexes can be negative integers.

Given a string variable named theString, what are the valid indexes for that string? Press provide an answer that will work for any string stored in theString.

A(n) __________ is a variable that receives a value that is passed into a function when it is called.

Write a function that accepts two numeric values and returns the larger of the two. DO NOT use the built-in max function, write the code to determine the larger of the two values.  An example of calling your function could be: a = 10 b = 20 maxValue = myMax (a, b)  #maxValue will be 20

As a rule, functions should be kept relatively small.

(BONUS) A company has sales revenues of $260,000 and expenses of $65,000. What is its net profit margin?

Using the letters corresponding to the stages in the physiology of muscle contraction, write the events of muscle contraction in chronological order in the space provided. Note:  The first step begins somewhere in the neuron as I want to determine if you still understand some of the steps that take place in the neuron from previous notes.     a. Action potentials are conducted in a motor neuron and arrive at the terminal of the axon.     b. Action potentials stop being produced, SR accumulates calcium and the troponin-tropomyosin complex moves again to its inhibitory position.     c. ACh diffuses across cleft and binds to ACh receptors.     d. Action potentials are conducted across the muscle cell membrane (sarcolemma).     e. Shape change in troponin causes tropomyosin to shift position in the actin filament, thus exposing binding sites for the myosin cross-bridges.     f. Attachment of another ATP allows the cross bridge to detach from the actin and repeat the cycle over again as long as Ca2+ remains attached to troponin.     g. Binding of ACh to receptors opens up ion channels on muscle cell membrane that causes EPP’s and a      depolarization of the muscle.     h. Myosin cross-bridges bind ATP, attach to actin, and undergo a power stroke.       i. Voltage-gated Ca2+ channels open in pre-synaptic terminal and Ca2+ enters cell.      j. Ca2+ attaches to troponin, causing a conformational change in its structure.     k. T tubules conduct action potentials deep into the muscle fiber.     l. Ca2+ entry causes the release of ACh at the neuromuscular junction.   m. Action potentials in the T tubule stimulate the release of Ca2+ from the terminal cisternae.

Using the following scheme, fill in the blanks.      Stimulus  Increased blood Ca2+     Endocrine tissue activated   _______ (Include specific cells producing hormone and gland in which you find those cells)     Hormone released _______     A target organ _______     Response of target organ _______ (Also, remember also to say if the response is increased or decreased)
