The answer to this question would be: prostate glands
The term upper end is a bit ambiguous and it should be better to call it the proximal end of the urethra. The upper ends of the urethra, near the bladder, there is an organ called prostate. The prostate is a gland that only found in males as its function was to produce seminal fluid, make it a bit alkali.
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
Answer:
6.75l l/min
Explanation:
Streptomycin is extracted from the fermentation broth using an organic solvent in a counter current staged extraction unit.
for 5 stage counter current staged extraction unit for streptomycin
X5 = 0.2g/l
X0 = 10.0g/l
X5/X0 = 0.02
given
Xn/X0, E, and
n = 5
A estimate of E can be evaluated directly;
E = 1.8
= LKd/H
by substituting the given values; Kd = 40, H= 150l/min
then we have,
L;L = 1.8(150)/40
= 6.75l l/min
Answer:
The correct answer is option C.
Explanation:
Human subject research is an investigation or research that include human as the subject. In other words, An Investigator conducts clinical research on humans getting data through interaction and intervention of individuals.
investigator A has investigated biological specimens. These specimens are coded and linked to the identifiers. Investigator B's research using biospecimens human subject is not according to the human subject research in the federal regulations as investigator B did not get the individual identifiers.
Thus, the correct answer is option C.
