Answer:
The correct option is <u>C:</u> Posterior clinoid processes and dorsum sellae.
Explanation:
An Anteroposterior (AP) axial projection (Towne method) is a <em>radiograph of the skull</em> used to evaluate and demonstrate the <em>presence or state of fractures</em>.
Structures that can be seen are the entire <u>occipital bone</u>, the <u>petrous part of the pyramids</u>, and the <em>foramen magnum</em>. Through this last one, there can be seen the dorsum sellae and the posterior clinoid processes.
The answer to this question is the term parasitism. A parasitism is a non-mutual relationshio between species where in the other specie benefit from the other. The specie that benefit is called a parasite while the specie that was being used by the parasite is called the host.
Red blood cells will swell and burst. The
reason behind this is that red blood cells are okay when they are in
the plasma (the watery part of the blood) because the solutes in plasma
are so well balanced that plasma is rendered isotonic. An isotonic
solution is a type of solution that has the same salt concentration as
its surrounding environment and thus the substances around it e.g. cells
neither gain nor lose water. In the blood plasma, the red blood cells
neither lose nor gain water and so they remain intact.<span>However distilled
water is hypotonic (has less or no solutes) and therefore osmosis will
take place when red blood cell which have a higher solute concentration
are placed in it. Water molecules will leave the distilled water and
pass into the red blood cells through the semi-permeable membrane of the
cells in an attempt to equalize the difference in osmotic pressure on
either side of the membrane. In so doing, water will accumulate in the
cell which will then swell to capacity and ultimately burst.</span>
The main signal in small intestine for pancreatic bicarbonate ion secretion is Secretin.
When food from the stomach with acidic medium enters duodenum(first part of small intestine) it stimulates the lining of duodenum cells to release the hormone secretin.
This hormone travels via bloodstream to pancreas and stimulate to it to release bicarbonate ions.Now these ions enter duodenum and neutralise the acidic medium.
This results in the optimum pH for the enzymatic action to take place thereby promoting final digestion of protein.
