Receptor Protein Protein that binds to a specific single molecule‚ enabling the cell to respond to the signal molecule. i.e. The muscles of a person exercising can not contract without receptor proteins and signal molecules that tell the muscles when to contract and when to relax. Second Messenger Signal molecule produced in response to the binding of a chemical signal. Acts as a signal molecule in the cytoplasm. Signal Molecule Carries information throughout the body and to other

1. A 1.4M Hz carrier is modulated by a music signal that has a frequency components from 20 Hz to 10k Hz. Determine the range of frequencies generated for the upper and lower sidebands. Solution: Upper Side Band = 1‚ 400‚ 000 Hz + 20 Hz = 1‚400‚ 020 Hz Up to = 1‚ 400‚ 000 Hz + 10‚ 000 Hz = 1‚ 410‚ 000 Hz Lower Side Band = 1‚ 400‚ 000 Hz – 10‚ 000 Hz = 1‚ 390‚ 000 Hz Up to = 1‚ 400‚ 000 Hz – 20 Hz = 1‚ 399‚ 980 Hz 2.

difference between learning styles and learning modalities.[1] Learning styles: what do we know?[2] What are learning styles?[3] Learning styles are simply the way a child learns best.[4] Learning styles theory says that there are different learning modalities and that individuals have a preferred modality.[5] A consequence of this theory is that effective teaching should present a variety of teaching methods which cover all three learning modalities so that different students have equal opportunities

Fear Induced Emotion on Motivation University of Texas at Arlington Anxiety is a psychological‚ physiological‚ and behavior state in humans and animals by a threat to well-being or survival‚ either potential or actual. Each of us has felt afraid‚ and we can all recognize fear in many animal species. The function state of fear is defined in terms of being caused by a particular pattern of adaptive behavior to avoid or cope with that threat. We have all been in a situation where we are in fear

The Fiscal Stimulus‚ Flawed but Valuable But I’m also an empirical economist who’s spent a career trying to estimate the effects of monetary and fiscal policy. So let me put on my empiricist’s hat and evaluate what we know about the legislation’s effects. After listening to Representative Paul Ryan in the vice-presidential debate‚ you might think that careful evaluation isn’t needed. In his view‚ we spent $800 billion on the stimulus‚ yet unemployment still rose to 10 percent — so obviously it

Amplitude modulation or AM as it is often called‚ is a form of modulation used for radio transmissions for broadcasting and two way radio communication applications. Although one of the earliest used forms of modulation it is still in widespread use today. The first amplitude modulated signal was transmitted in 1901 by a Canadian engineer named Reginald Fessenden. He took a continuous spark transmission and placed a carbon microphone in the antenna lead. The sound waves impacting on the microphone

Imagine that after you die‚ people spread malicious rumors about you so that everyone comes to believe that you were a terrible person. Does this affect your well-being? If it does‚ how do you explain how your well-being can change after you have died? Now first of all‚ let me address the situation of being dead and still having well-being. For the sake of this argument
