<span>4. Species

</span><span>Allopatric speciation is were a single species has been separated so long they have both evolved slightly in different "directions" that prevent them from breeding after being reintroduced.</span>

Blood flow (liter/min) through the pulmonary circuit equals blood flow through the systemic circuit, but pulmonary resistance is
GenaCL600 [577]

Answer:

The number of liters, or amount of blood that circulates through all the systems of the human body is always a constant one. However, how much of the total amount of blood in the human body passes through the two major circuits (systemic and pulmonary) depends not just on the volume of blood, but also on other factors such as the size of the vessels through which the blood flows and the amount of muscular layers, or any form of tissue, that will offer resistance to that flow. Because pulmonary vessels are smaller in size, and because the need for speed in flow in that circuit is not paramount, as its purpose is to load oxygen and unload CO2 to the lungs, the mean pressure is smaller thain in the systemic flow.

Using, however, the equation on the question, to prove that mean pulmonary blood pressure is 5 times less than that of systemic blood pressure, we would have the following:

1. F= pressure/ systemic resistance

2. Flow= pulmonary flow.

3. Systemic resistance = 5x pulmonary resistance

4. Systemic pressure/ systemic resistance = pulmonary pressure/ pulmonary resistance.

5. Systemic presure x pulmonary resistance/ (5x pulmonary resistance) = Pulmonary pressure.

6. Pulmonary pressure= systemic pressure/5

If there was a fungicide that killed all fungi, make a prediction on how that would affect the ecosystem and eventually us human
marishachu [46]
Fungi is what decomposes things and puts nitrogen back into the ground. without the fungi plants would soon begin to run out of the nutrients they need. lack in vegetation would soon form. animals would then start to die of or migrate to different locations. so eventually you would begin to see less food and more wildlife in town because of the food shortage.

A person had an infection of his Peyers patches and development intestinal cancer. How could these two Events be related?
BigorU [14]
Peyer's patches are lymphatic tissue patches that are located in the small intestine. The lymphatic system provides an immune response for the body, so if there was an infection of the Peyer's patches, the body's defense system in the small intestines, which would make the intestines more susceptible to cancer or infection.
