Answer:
"The prominent bony ridge that you can palpate across the posterior surface of the scapula is the <em>scapular spine"</em>.
Explanation:
A scapula is a plane and triangular bone located in the superior and posterior part of the thorax. The <em>posterior face</em><em> of the bone is divided into the supra-spiny fossa and infra-spiny fossa</em>. These two areas are <em>divided by the </em><em>scapular spine</em>. This is a <em>bony formation</em> that <em>goes from medial to the lateral</em> side of the scapula <em>and finishes</em> in one of the extremes as a bulky prominence called <em>acromion</em>.
The spine is easily palpable through the skin.
The plastic and its usage has its supporters and critics, with both making good points, as the plastic is a material that both has its big advantages, but also its big disadvantages.
The main advantages of the plastic is that it is very cheap, the products with it are very easy for production, and it can be recycled numerous times. Also, it is very easy and practical for usage.
The main disadvantages are that the plastic needs lot of time to dissolve, depending on the type of plastic it can be anywhere from few hundred to few thousands years. Also, when it disposes it releases a lot toxic chemicals into the soil, and those chemicals are very harmful for the living organisms.
Big problem is also that most of the plastic is not being recycled, but it is thrown away, so there's enormous plastic waste everywhere in the world. Big portion of it is burned, and by burning it lot of toxic chemicals are released into the air, and that causes lot of pollution.
