active satellites are receives the transmitted signal from earth ,amplify the signal and transmit it. it is also called as transponders. but passive satellites just receive and transmit the signal.itac as the reflector
Explain Active and Passive transport.
The passive voice is when the subject of a sentence receives the action. For example, "The book was read by me." The active voice is when the subject performs the action. For example, "I read the book." The active voice is often preferred for its directness and clarity.

Endocytosis is an example of active transport.
In passive satellite system the ground transmitting system power at the reflector. The receiving ground system received a function of the power that has been intercepted by the reflector. In active satellite received the function of the energy band toward it by the ground transmitter system and the received power is active amplitude by active electronic means.
Osmosis is an example of Passive Transport.
Coupled transport is an example of active transport.
An active satellite acts as a REPEATER; it amplifies signals received and then retransmits them back to earth. This increases signal strength at the receiving terminal to a higher level than would be available from a passive satellite. A passive satellite only reflects received radio signals back to earth. fr0m: ZIA UR REHMAN D-05-ES-29 DCET Karachi Pakistan.
Explain Active and Passive transport.
A passive sentence says that something happened but doesn't say who caused it to happen. For example: food was eaten. An active sentence says who did it. For example: Tom ate the food.
Diffusion is an example of passive transport, like osmosis(the diffusion of water through a membrane).
The passive voice is when the subject of a sentence receives the action. For example, "The book was read by me." The active voice is when the subject performs the action. For example, "I read the book." The active voice is often preferred for its directness and clarity.
To change a sentence from active to passive voice, move the object of the active sentence to the subject position in the passive sentence and add a form of the verb "to be" along with the past participle of the main verb. For example, "I ate the cake" in active voice becomes "The cake was eaten by me" in passive voice.
You change passive voice to active voice by making the actor(s) the subject of the sentence, e.g., "the question was asked by the user" (passive) versus, "the user asked the question" (active).
