After reаding the pаrаgraphs belоw, answer the questiоn that fоllows.Mr. and Mrs. Smith have three sons in elementary school. Two of their children are progressing normally, but their youngest son, Charles, has been much slower than his siblings in developing speech and language skills. His parents are concerned that he has a learning disability and decide to investigate further. Since some learning disabilities can be genetically based, their pediatrician recommends a chromosomal analysis.The results show that Charles has a trisomy of the sex chromosomes, diagnosed as XYY. A mistake during sperm formation resulted in an extra copy of the Y chromosome. The extra copy was passed on to Charles during fertilization. Most often, this chromosomal change causes no unusual physical features or medical problems, but those with trisomy of the sex chromosomes may have a higher-than-normal risk of delays in learning development.During which stage of meiosis could this mistake have occurred?

Lоng Questiоn 3 Prоblem StаtementHere is а very simplistic model of а (rear-wheel drive) electric car run by a dc motor.The armature resistance of the motor is R = 1 Ohm, the armature inductance is about 0, the motor torque and back emf constants are both K = 10 , and the rotational inertia of the motor’s armature is 0. The total mass of the car is M = 1000 kg and the car moves in the air with linear air drag cv, where c = 2.When you apply the voltage V to the motor, it provides a motor torque Tm and motor angular speed wm to the input of the transmission. The transmission then delivers the torque Tw and speed ww to the rear wheels. The gear ratio of the (very light & frictionless) transmission is G = 5 . Assume the wheels too are very light and have radius r = 0.25 m, and don’t slip on the road. (All units are SI)Your Objective (4 points) Write the equation relating motor voltage to motor torque and motor angular speed: V= a*Tm + b*wm. Write this equation with numerical values of a and b filled in. And show steps leading to those values. (2 points) Transmission equation relating motor torque to total force on the rear wheels from ground:F = d*Tm. Write this equation with numerical value of d filled in. And show steps leading to that value. (2 points) Transmission equation relating motor speed to car speed:wm = e*v. Write this equation with numerical value of e filled in. And show steps leading to that value. (4 points) Equation of motion of the car:F = f*v + g*vdot. Write this equation with numerical values of f and g filled in. And show steps leading to those values. (8 points) Paste a snapshot of the block diagram showing all these equations graphically. The input of the block diagram should be voltage V and output should be car speed v. I don't need a reduced TF from V to v, I just need the block diagram not the final TF. You are welcome to use symbols a, b, d, e, f, g, etc. in the diagram, if you are worried your values may not be correct from the previous parts.Clearly label all the signals (lines, wires) and summation junctions. Clearly put proper TFs in each block needed in the diagram. HintsSpeed v of the car, assuming no slipping of the wheel, is related to angular speed of the ww and radius of the wheels as: v=rww.In going from the motor to the wheels through the transmission, while the torque increases by a factor of G (assuming no friction and massless gears), the angular speed decreases by the same factor G.
