Write a small program, in pseudocode or otherwise, that demonstrates a recursive algorithm. Write a small explanation of how recursion is used in your program.

The Fibonacci sequence is defined as: f(n) = f(n-1) + f(n-2)F(0) = 1F(1) = 1 Where n is a positive number. This allows for a recursive algorithm to be written that returns 1 for the two base cases, and retur...

Use your knowledge of the actin and myosin mechanism of muscle contraction to explain how a vesicle might be "walked" along the cytoskeleton of a cell.

ATP binds the myosin head in its resting state. ATP is hydrolysed to ADP + Pi, releasing energy. This changes the conformation of the myosin head, cocking it. The myosin head reattaches to the actin molecule...
