Answer:
The answer to your question is: below
Explanation:
Reaction with water, sodium is very reactive, sometimes explosive with water, so we can identified it from the other metals. Magnesium is less reactive than sodium, but in the presence of water it can produce bubbles.
Then we can identify copper and stainless steel because of the shine and they conduct electricity (conductivity).
It is past on to the next conductor of the energy
A ribosome is made from complexes of RNA's and proteins
Sound spreads in the medium in the form of concentric spheres known as wave-fronts.
Now, as each wave-front expands, it moves away from the source of the sound and expands at a wider space. This means that its energy decreases and the sound becomes quieter.
So, overall, as sound spreads in spheres:
1- The energy per wave decreases
2- The amplitude of the wave decreases
3- The sound becomes quieter as the sphere moves further away from the source

Answer:
A
Explanation:
Unconfined aquifers are those into which water seeps from the ground surface directly above the aquifer. Confined aquifers are those in which an impermeable dirt/rock layer exists that prevents water from seeping into the aquifer from the ground surface located directly above.
