How can signal molecules remain outside of cells but still create changes in activity inside cells?
Signal molecules can bind to specific receptors on the cell surface, which triggers a series of signaling events inside the cell. This can lead to changes in enzyme activity, gene expression, or cellular processes. The signal molecules do not need to enter the cell to create these changes as the signaling events are often propagated through complex cascades of cellular machinery.
What is an electrical signal in a neuron used to send messages in the body called?
An electrical signal in a neuron used to send messages in the body is called an action potential. This signal is generated by the flow of ions across the neuron's membrane when it reaches a certain threshold, leading to the propagation of the signal along the neuron.
What is signal intensity with the medial meniscus?
Signal intensity refers to the brightness of an image on a magnetic resonance imaging (MRI) scan. When evaluating the medial meniscus, signal intensity can help identify abnormalities such as tears or degeneration. Changes in signal intensity of the medial meniscus can indicate injury or pathology.
What are the expected shapes of photometric titration?
The expected shapes of photometric titration typically follow sigmoidal curves, with a rapid increase or decrease in signal intensity as the analyte concentration changes. At the beginning, the signal intensity changes slowly, then increases more rapidly, followed by a plateau where the signal levels off. This shape is indicative of the gradual binding or reaction between the analyte and titrant.
What is T2 bright signal changes in the brain?
T2 bright signal changes in the brain typically indicate the presence of increased water content in the affected area, which can be due to various conditions such as inflammation, infection, edema, or demyelination. These changes are commonly seen on magnetic resonance imaging (MRI) scans and can help in diagnosing different neurological disorders.
Yes, It just changes the connector size, not the signal.?
Yes, It just changes the connector size, not the signal.
What will happen to the next nerve cell whet it gets 'hit' by neurotransmitters?
When a nerve cell is hit by neurotransmitters, it can undergo changes in its electrical potential, leading to a signal transmission along the cell. This signal can trigger various cellular responses, such as the release of other neurotransmitters, activation of signaling pathways, or even changes in gene expression. Ultimately, these cellular responses contribute to the communication within the nervous system.
Fats oils and waxes are all classified as what?
Fats, waxes and oils are all also known as lipids.
What is the difference between multichannel and multidimensional signals?
if a signal is a function of single independent variable,then signal is called multichannel signal. if a signal is function of multiple independent variable then signal is called multidimensional signal.
What is an AC source?
signal value changes with time
Where does the name modem come from?
It is a device that changes the digital signal from a computer into the analogue signal more suited to a phone line, and the analogue signal from phone line into the digital signal for the computer to use. These two processes are called modulation and demodulation. The word modem comes from these two words: MOdulation and DEModulaion = MO DEM.
What is it called when you convert a digital signal to analog?
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
Name the process in a radio which make the signal stronger before the loudspeaker changes it to a sound signal?
Amplification.
What is a reflected radar signal called?
A reflected radar signal is called an echo.
What is slope overload error in delta modulation derive an expression for it?
: If the input signal amplitude changes fast, the step by-step accumulation process may not catch up with the rate of change of the signal this is called slope overload error
What changes or signal in the environment that can make an organism react is?
Stimuli
What is the modulating frequency of amplitude modulation?
the frequency range of an am wave is 20herz to 20kilo herz
