I need help with a question in Introduction to programming using VISUAL BASIC 10th edition, ch 7 PP8, I am lost on how to write the code. How is the code written in VISUAL BASIC and why? Below is the question I am referring to. Airline Reservations: Write a reservation system for an airline flight. Assume the airplane has 10 rows with 4 seats in each row. See Fig 7.90. Use a two-dimensional array of strings to maintain a seating chart. In addition, create an array to be used as a waiting list in case the plane is full. The waiting list should “first come, first served,” that is, people who are added early to list get priority over those added later. Allow the user the following three options. (a) Add a passenger to the flight or waiting list. 1. Request the passenger’s name. 2. Display a chart of the seats in the airplane in tabular form. 3. If seats are available, let the passenger choose a seat. Add the passenger to the seating chart. 4. If no seats are available, place the passenger on the waiting list. (b) Remove a passenger from the flight. 1. Request the passenger’s name 2. Search the seating chart for the passenger’s name and delete it. 3. If the waiting list is empty update the array so the seat is available. 4. If the waiting list is not empty, remove the first person from the list, and give him or her the newly vacated seat (c) Quit seating Chart Nome Sest (TA 1B, 1C. 1D, 2A10D) Add Passenger Delete Passenger Quit Waiting ist FIGURE 7.90 Possible outcome of Programming Project 8

What evidence supports the conclusion that the SLC24A5 gene contributes to the production of melanin in humans in the same way it does in fish? Select all that apply. Hint: Review the section of the paper entitled “Conservation of golden gene structure and function in vertebrate evolution.” A)Injection of golden zebrafish larva with human SLC24A5 messenger RNA (mRNA) restores the fish’s ability to make melanin. B.)The slc24a5 protein produced by the gene in the zebrafish is 68 – 69% similar to the SLC24A5 protein in humans. C)At least 93% of East Asians share the same G allele of the SLC24A5 gene with Africans, yet East Asians are usually light skinned. D)The zebrafish slc24a5 gene and the human SLC24A5 gene are both expressed at high levels in skin and eyes.

(1 point) Determine the average rate of change of the following function between the given values of the variable: f(x) = x4 - - X; x = -2, x = 3 Average rate of change = .

Question Suppose three point masses are placed in the xy-plane as follows (assume coordinates are given in meters): mi = 5 kg, placed at (-2, -3) m2 = 3 kg, placed at (2,3) 'm3 = 2 kg, placed at (-3, -2) Find the center of mass of the system. Write your answer as an ordered pair Provide your answer below:

let f(x)= x^2-5, g(x)= 2x^3+x and p(x)= f(x)g(x). a) computedp/dx b) compute f'(x)g'(x)
