Rock A = It is a metamorphic rock that experienced tremendous heat and pressure due to massive, moving tectonic plates.
Metamorphic rocks are rocks that have been somewhat squished and transformed by heat and pressure. These rocks often have different layers as the rocks go through pressure and are literally look like rocks that have been piled up and then stuck together. The best indicator of this rock being a metamorphic rock is the wavy elongated stripes. The stripes are created from the different rock elements being pressed together over time.
Rock B = It is a sedimentary rock made primarily from lithification of organic material.
Sedimentary rocks are rocks that have been formed by different substances that come together due to the different weather conditions. The best indicator of this being a sedimentary rock is how the rock came together and looks like a bunch of shells were glued together.
Rock C = It is an igneous rock that was formed above Earth’s surface.
Most igneous rocks have smooth outer layers. These rocks are often made with solidified magma from volcanoes. The best indicator of this being an igneous rock is the indication of it being a solidified piece of magma.

<h3><u>Answer;</u></h3>
Gap junctions
<h3><u>Explanation;</u></h3>
- Gap junctions allow the exchange of ions, second messengers, and small metabolites between adjacent cells and are formed by two unrelated protein families, the pannexins and connexins.
- <em><u>Action potentials generated by the autorhythmic cells spread waves of depolarization to contractile cells through gap junctions. If the depolarization causes the contractile cells to reach threshold, they will in turn generate an action potential.</u></em>
