The valves prevent the backward flow of blood. These valves are actual flaps that are located on each end of the two ventricles (lower chambers of the heart). They act as one-way inlets of blood on one side of a ventricle and one-way outlets of blood on the other side of a ventricle.
Explanation:
The basic principles that apply to circuits is that electrons must receive energy from a source, and electrons transfer energy to perform some useful function.
<h3 /><h3>What is circuit?</h3>
Individual electronic components, like resistors, transistors, are connected by metallic wires or traces by which the electric current can flow to form a circuit design.
The basic principles that apply to circuits will be;
1. Electrons must receive energy from a source.
2. Electrons transfer energy to perform some useful function.
Hence, option 1 and 2 are correct.

Answer:
<em>A = 0.05 V</em>
Explanation:
<u>Sinusoidal Functions</u>
A sinusoid or sinusoidal function is a sine or cosine which general equation is
Or also
Where A is the amplitude or maximum value, w is the angular frequency, t is the time and 
is the phase shift.
Comparing the given expression with the general formula
We can establish that A=50 mV = 0.05 V
Genital warts are warts that are near or on a person's genital areas. For a girl, that means on or near the vulva (the outside genital area), vagina, cervix, or anus. For a guy, that means near or on the penis, scrotum, or anus. ... Genital warts are caused by a group of viruses called HPV (short for human papillomavirus).
