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.
35 parts per thousand
Sea water. Seawater is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of approximately 3.5%, or 35 parts per thousand. This means that for every 1 litre (1000 mL) of seawater there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it.
