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.

Carbohydrates provide your body with glucose it needs to function properly. Two types of carbohydrates exist: complex carbohydrates and simple carbohydrates. Complex carbohydrates take time to break down into glucose. Foods rich in complex carbohydrates and fiber are called good carbohydrates.Simple carbohydrates include sugars found in foods such as fruits and milk products and sugars added during food processing. Foods rich in white flour and added sugars are called bad carbohydrates.arbohydrates provide your body with glucose it needs to function properly.
