# A second messenger transmits the signal into the cell, eliciting a physiological response.

An example of an ion allowed into the cell during a ligand-gated ion channel opening is Ca < sup > 2 +</ sup >; it acts as a second messenger initiating signal transduction cascades and altering the physiology of the responding cell.

Then a tunable local oscillator and mixer converts that signal to a second much lower intermediate frequency where the selectivity of the receiver is accomplished.

Exchange operation soon resulted in telephones being equipped with a bell in a ringer box, first operated over a second wire, and later over the same wire, but with a condenser ( capacitor ) in series with the bell coil to allow the AC ringer signal through while still blocking DC ( keeping the phone " on hook ").

If one of the two events represents the sending of a signal from one location and the second event represents the reception of the same signal at another location, then as long as the signal is moving at the speed of light or slower, the mathematics of simultaneity ensures that all reference frames agree that the transmission-event happened before the reception-event.

At 08: 47, the plane's transponder signal changed once, and a second time within a minute, and the aircraft began deviating from its assigned course.

The code had a dual meaning: first to signal slaves to prepare to escape and second to give clues and indicate directions on the journey.

The second involves something deeper, but its characteristic form focuses on a shift in policy for the community, not in the truth on which the community rests.

Notice that the second condition in the definition itself refers to natural numbers, and hence involves self-reference.

However, with the appropriate reduction formula, every elliptic integral can be brought into a form that involves integrals over rational functions and the three Legendre canonical forms ( i. e. the elliptic integrals of the first, second and third kind ).

" This second case usually involves the town bully and mischief maker Bugs Meany, leader of a gang who call themselves the Tigers, who, after being foiled, will attempt revenge in the third mystery.

Faith involves more than outward obedience to this authority, but also must be based on a deep personal understanding of religious teachings. By faith is meant, first, conscious knowledge, and second, the practice of good deeds.

The Multiple Kick is usually done in the " second " style described in the Side Kick article which " involves shooting the leg forward as in a front kick and then pivoting and turning so " to actually deliver a side kick.

Money laundering often occurs in three steps: first, cash is introduced into the financial system by some means (" placement "), the second involves carrying out complex financial transactions in order to camouflage the illegal source (" layering "), and the final step entails acquiring wealth generated from the transactions of the illicit funds (" integration ").

The first is a ritual designed for the individual, which involves sacrificing a " Cake of Light " ( a type of bread that serves as the host ) to Ra ( i. e. the Sun ) and infusing a second Cake with the adept's own blood ( either real or symbolic, in a gesture reflecting the myth of the Pelican cutting its own breast to feed its young ) and then consuming it with the words, " There is no grace: there is no guilt: This is the Law: Do what thou wilt!
