#1 Define blood pressure. Differentiate between systolic and diastolic blood pressure. What is "normal" blood pressure for a young adult?

Blood pressure is the force that the blood puts on the walls of the blood vessels. Systolic pressure is the peak pressure in the arteries which is seen around the end of the cardiac cycle when the ventricles contract. Diastolic pressure is the minimum pressure in the arteries which is seen around the beginning of the cardiac cycle when the blood fills ...

Biology Problems: statistics (mean, variance, standard deviation, standard error), sequence of genes

47. Corn plants from a test plot are measured, and the distribution of heights at 10-cm intervals is recorded below.

(see chart in attached file)

Calculate (a) the mean height, (b) the variance (c) the standard deviation, and (d) standard error of the mean.

48. The genes dumpy wing (dp), clot eye (cl), and apterous wing (ap) are linked on chromosome 2 of Drosophila. In a series of two-point mapping crosses, the following genetic distance were determined:
dp-ap 42
dp-cl 3
ap-cl 39

What is the sequence of three genes?
