Write a program that prints inverted trapezoids using the character '-'. The user will enter the number of '-' characters on the first row and then the number of rows forming the trapezoid. For instance, an inverted trapezoid with 7 '-' characters in the first row and 3 rows forming the inverted trapezoid looks like: --- No row is allowed to have less than two '-' characters. You will write code to check for this. Determine the appropriate loop(s) to use (while loop or for loop) when a task requires looping. Study the tests below to help you understand program behavior. Use the following tests and your own tests to run against your solution in Develop mode. These are the same tests that your solution will be executed against when you submit your work in Submit mode. User input is in bold:

Which best describes the role or restriction enzymes in the analysis of edna a. to break dna into fragments that vary in size so they can be sorted and analyzed b. to amplify small amounts of dna and generate large amounts of dna for analysis c. to purify samples of dna obtained from the environment so they can be analyzed d. to sort different sizes of dna fragments into a banding pattern that can be analyzed

5.a fishing rod is formed from a composite material of 0.5 kg of glass fibers embedded in a matrix of 0.5 kg of epoxy resin. the glass fibers are assumed to be long, continuous and unidirectional. to achieve a greater stiffness it is proposed to use a different composite that is comprised of long continuous carbon fibers that will be embedded in a matrix of 0.5 kg of epoxy resin. if the modulus of elasticity of the carbon fiber composite is 10% greater than the elastic modulus of the glass fiber composite, estimate the mass of carbon fibers that will be used to make the carbon fiber composite. assume the applied tensile stress is parallel to the direction of the long axis of the fibers. the epoxy resin, glass fiber, and carbon fiber have an elastic modulus of 5, 86, and 350 gpa respectively and a density of 1100, 2500, and 1800 respectively.
