A resistorâcapacitor circuit (RC circuit), or RC filter or RC network, is an electric circuit composed of resistors and capacitors driven by a voltage or current source. A first order RC circuit is composed of one resistor and one capacitor and is the simplest type of RC circuit.RC circuits can be used to filter a signal by blocking certain frequencies and passing others.s : So at DC (0 Hz), the capacitor voltage is in phase with the signal voltage while the resistor voltage leads it by 90Â°. As frequency increases, the capacitor voltage comes to have a 90Â° lag relative to the signal and the resistor voltage comes to be in-phase with the signal.
Making the world better, one answer at a time. The carbohydrate chains on membrane proteins serve as recognition markers; they aid in cell-to-cell recognition.aking the world better, one answer at a time.

What is the difference between a simple carbohydrate and a complex carbohydrate? The body breaks down carbohydrate into glucose (a type of sugar) to provide energy. The number of sugars found in the chemical structure of the carbohydrate determines if it is a simple or a complex carbohydrate. Simple carbohydrates contain no more than two sugars. Carbohydrates with more than two sugars in their structures are considered complex carbohydrates. Compared to simple carbohydrates, complex carbohydrates are generally absorbed slower and thus take longer for the body to digest.
