Answer:
Barr bodies are small bodies that are dark staining bodies that show the inactivated X chromosome, these sex chromatin bodies attach to the membrane of the nucleus of interphase cells.
One less of the total number of X-chromosome (n-1) represents the number of Barr bodies.
Then,
The number of Barr bodies with Klinefelter would be:
Klinefelter (47,XXY): (n-1) = (2-1) = 1 Barr body as here two X chromosome present.
Similarly, for
Turner (45,XO): (n-1) = (1-1) = 0 Barr bodies (X chromosome = 1)
Now, as per the question, the bar bodies for karyotypes given
47,XYY: (n-1) = (1-1) = 0 Barr bodies
47,XXX: (n-1) = (3-1) = 2 Barr bodies
48,XXXX: (n-1) = (4-1) = 3 Barr bodies
If there is powdered sugar on top of that doughnut. It would be the sugar on and in the doughnut
Most likely, it would effect many trees depending on the rate of infection and how much of this microorganism is released to the environment. I hope that helped :)
The possible cause for a decrease in ecosystem productivity is : B. a decrease of the biodiversity o an ecosystem
Decrease in biodiversity means that there will be less organisms that support each other to maintain the balance in the ecosystem, which eventually decrease its productivity
