The speed of the cross country runner is equal to 4 km/min.

<u>Given the following data:</u>

Distance = 8 km.

Time = 2 minutes.

To determine the speed of the cross country runner:

Speed can be defined as the distance covered by an individual per unit time and it can be measured in kilometer per minutes (km/min).

Mathematically, speed is given by the formula;

$Speed = \frac{distance}{time}$

Substituting the given parameters into the formula, we have;

$Speed = \frac{8}{2}$

Speed = 4 km/min.

Mrs. patton has been 3 weeks past her due date to have her first baby. you decide you need to induce labor by giving her an inje

Maksim231197 [3]

The hormone to be given is oxytocin. Oxytocin is a hormone produced by the paraventricular nuclei of the hypothalamus then stored in the posterior pituitary gland (along with antidiuretic hormone or vasopressin) that is responsible mainly for uterine contraction and milk ejection or letdown. Oxytocin induces contraction of the myoepithelial cells in the breast for milk letdown. On the other hand, there is upregulation of oxytocin receptors during parturition which makes the uterus more sensitive to oxytocin. Oxytocin is also known to induce labor and reduce post-partum bleeding.
