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.
Eye placement probably evolved for different reasons in different groups of animals.
Frogs have a much larger field of view than humans, due to the placement of their eyes. The eyes, situated on the top and sides of the head, allow them to see almost 360 degrees around them (which helps for a species that can’t turn its head). So the frog can see prey and preditors on both sides of its body with ease.
Human is a predator, they have forward facing eye instead of side eye. Forward facing eyes allow for binocular or stereoscopic vision, which allows an animal to see and judge depth. Predators need this depth perception to track and pursue prey.
Answer:
Earthquake, and geology-related
Explanation:
I think what they are showing are two tectonic plates that shifted along a fault line.
They evolved from cyanobacteria
