What is a indicator organisms?
Indicator organisms are organisms that are sensitive to changes in the environment. When populations of indicator species changes, it can signal a change in the environment that will eventually effect other species as well.

What is a signal in which organisms respond?
Stimulus
How can signal molecules remain outside of cells but still create changes in activity inside cells?
Signal molecules bind to specific receptor proteins on the outside surface of the plasma membrane. This triggers a chain reaction of events that passes the signal to molecules inside the cell
The process that allows a message to be carried across a membrane?
active transport, because it uses energy , while passive transport does not
Yes, It just changes the connector size, not the signal.?
Yes, It just changes the connector size, not the signal.
Fats oils and waxes are all classified as what?
Fats, waxes and oils are all also known as lipids.
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.
Name the process in a radio which make the signal stronger before the loudspeaker changes it to a sound signal?
Amplification.
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 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 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.
What changes or signal in the environment that can make an organism react is?
Stimuli
What are two groups of lipid?
There are four main groups of lipids. They are fatty acids, glycerides, non glycerides, and complex lipids. The groups are determined based on storage of energy, structure of cell membranes, and signal of chemical biological activities.
What is the modulating frequency of amplitude modulation?
the frequency range of an am wave is 20herz to 20kilo herz
What kind of signal consists of a current that changes in steps?
A square wave
