Hello! Your answer is W.
The layer W is called the convection zone. The lower bit of this zone is hotter (as it is closer to the core) and the outer is cooler. Since heat rises, liquid will rise in this zone, and then cool down, and sink again. This causes a circular transfer of energy.
Y and Z both transfer heat outwards - they are the radiative zone and the inner zone, respectively.
Hope this helps!
<span>Electron microscopes therefore allow for the visualization of structures that would normally be not visible by optical microscopy. Light microscopes are not able to see things in a larger magnification compared to electron microscopes. Also you're able to see in 3d in electron microscopes and you can't see in 3dimentsional in light microscopes.

Explanation:
Folding can change the position in which rock layers appear. sometimes, layers of rock are overturned so frequently that the youngest rock layer may appear on the bottom, which is the reverse of what is ordinarily expected.

Each sieve tube element is normally associated with one or more nucleated companion cells, to which they are connected by plasnodesmata (channels between the cells). Each companion cell is derived from the same mother cell as its associated sieve tube member. Sieve tube members have no cell nucleus, ribosomes, or vacues. Thus, they depend on companion cells to provide proteins, ATP, and signalling molecules
