Answer:
The correct answer is - 10.6666 channels.
Explanation:
Given:
numbers of clusters duplicated = 16 times
The frequency bands for mobile unit transmission are - 825 to 845 MHz
The frequency bands for base station transmission = 870 to 890 MHz
The required bandwidth for each one-way direction of channels = 30 kHz
Formula:
the number of simultaneous communications that can be supported by each system = /
Solution:
The required bandwidth for each two-way direction of channels = 2 × 30 kHz
then, according to the formula the number of simultaneous communications that can be supported by each system
= /
k_{sys} = 16×40/60
[b_{ch} = (845-825) + (890-870) = 20+20=40)]
= 10.6666.
A food web demonstrates which organisms transfer energy to other organisms. It helps maintain the ecosystem because if one life form went extinct, it could destroy the whole web.
The answer is C because water moves from an are to low solute concentration to an area of high solute concentration.
