What else can I help you with?
Is hydrogen a molecule?
Yes, hydrogen can exist as a molecule. In its diatomic form, hydrogen atoms can bond together to form a molecule called molecular hydrogen (H2).
How many atoms are there in a molecule of oygen?
There are 2 oxygen atoms in 1 molecule of oxygen.
How many carbon atoms are in the molecule ethanol?
There are four atoms of hydrogen in each molecule of methanol.
When a molecule has a positive end and a negative end it is called?
Molecules that have partially positive and negative regions are called polar molecules. Polarity results from an unequal attraction of electrons between the atoms that make up a molecule. The electrons are more drawn towards atoms with a higher electronegativity, thus making these atoms partially negative.
What is the size of a glycerol molecule in Angstroms?
The radius of a glycerol molecule is about 4.35 angstroms.
What amplifies the communication from a signal molecule?
penis
What amplifies communication from a signal molecule?
Receptor proteins on the cell membrane or inside the cell amplify the signal from a signal molecule by initiating a cascade of intracellular events, leading to a cellular response. This amplification allows the cell to respond effectively to low concentrations of the signal molecule.
Which device amplifies the incoming signal and noise?
Amplifier repeater
What is meant by amplifier?
An amplifier amplifies the small input signal to a high signal without changing its freqency.
What does a Car Amplifier do?
It "amplifies" the signal of your stereo so it is louder to hear.
What does an amplifier do to a small input signal?
amplifier will strengthen da small input signal n amplifies it
What is an amplifier repeater?
A repeater that does not distinguish between noise and signal; it amplifies both.
Is repeater an amplifier?
A repeater that does not distinguish between noise and signal; it amplifies both.
What is small signal amplifier?
As the name suggests, it amplifies a small signal. It ususally has a very high input impedance, to avoid affecting the source signal.
What 3 things can occur when a signal molecule binds to a receptor protein?
1. Change the permeability of membrane. 2. Form a Second messenger. (Amplifies the first signal inside the cell.) 3. Activates enzymes inside the cell. (speeds up reactions inside the cell=catalyze)
What is the verb for amplify?
Amplify is a verb. This device amplifies the signal from the microphone so that it can be heard.
Which of the following is characterized by a cell releasing a signal molecule into the environment followed by a number of cells in the immediate vicinity responding?
Paracrine signaling is characterized by a cell releasing a signal molecule into the immediate environment, where nearby cells can respond to the signal. This type of signaling allows for local communication within tissues.
