Which of the following is used to find the actual speed of the rotor (N)?

When does an induction machine work as a  generator? (N= Rotor Speed & Ns= Synchronous speed)

For the 3 genes shown below, what are the template strands? Image Long Description A horizontal diagram showing five connected rectangular boxes in a row. From left to right, the boxes are labeled: “P”, “Gene 1”, “Gene 2”, “P”, and “Gene 3”. Numbers “5′” and “3′” appear on the left side of the diagram, while “3′” and “5′” appear on the right side. The boxes are connected by straight lines, creating a linear sequence across the image.

Which statement about DNA strand orientation is TRUE?

DNA replication is described as semi-conservative because:

Why is the hypochromic effect (hypochromism) important in molecular biology experiments?  

What is the expected probability of a double crossover event between genes A, B, and C shown below?  Image Long Description A horizontal blue line with three points marked on it. Point A is on the left, point B is in the middle, and point C is on the right. The distance from A to B is labeled “10 cM” and the distance from B to C is labeled “25 cM”.

Calculate the Fixation index in the Subpopulation relative to the Total population based on the information provided. Image Long Description A mathematical equation. On the left side is “F_ST =” followed by a fraction. The numerator of the fraction contains “2pq – H” and the denominator contains “2pq”. All text appears to be in black on a white background. Image Long Description A table with a black header row containing three white text labels: “AA”, “Aa”, and “aa”. Below are two gray rows labeled “Pop. 1” and “Pop. 2” in black text on the left side. The table contains green decimal numbers: Pop. 1 shows 0.54, 0.20, and 0.26 across the three columns, while Pop. 2 shows 0.16, 0.40, and 0.44 across the three columns.

What is F for V-1? Hint: F takes into consideration all the alleles IBD. Probability of an allele IBD , where n= # of transmission events. Image Long Description A pedigree chart showing five generations labeled with Roman numerals I through V on the left side. The chart uses squares and circles connected by horizontal and vertical lines. In generation I, there is a circle labeled “A₁A₂” with number 1, connected to a square labeled “A₃A₄” with number 2. Generation II shows a square labeled 1, a circle labeled 2, a circle labeled 3, and a square labeled 4, all connected by lines. Generation III displays a square labeled 1, a circle labeled 2, a square labeled 3, a square labeled 4, and a circle labeled 5. Generation IV contains only a circle labeled 1, which has a diagonal line connecting it to square 3 in generation III. Generation V shows a single circle labeled 1 at the bottom of the chart.     Select the right answer and show your work on your scratch paper for credit.
