Aerobic exercise is the body producing energy WITH the use of oxygen (light activities like jogging). Anaerobic exercise produce energy without the use of oxygen and is typically a higher intensity that burns fat AND helps gain lean muscle mass (these are activities like weight lifting).
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 answer is electrophoresis. The electrophoresis can separate different length of DNA fragments using the agarose gel. The principle is that the DNA has negative charge and under constant volt it will move from negative to positive. And the longer the DNA is, the slower the DNA runs.
