Hi there!

Your answer is:

It is very important for the cell membrane to be semi-permeable because the ability to pick and choose what comes in and out of the cell keeps the cell safe! The membrane can choose to block out nasty germs and can also choose to get rid of internal waste.

An example of when this is important is in this scenario:

Let's say the cells are in a really salty solution. Naturally, salt will want to pull the water out of the cell. If the membrane wasn't semi permeable, the water would listen to the salt and leave the cell. This would cause cell death. BECAUSE the membrane is semi permeable, they can choose not to give the salt any water, keeping them alive

Hope this helps

Answer: A. endocarditis

Explanation:

Endocarditis is the inflammatory process of the endocardium, especially that located in the heart valves. There are several factors causing endocarditis, the most frequent and lethal being endocarditis caused by infectious agents. The most common mechanism is endothelial injury due to blood flow turbulence, be the one generated by a defective valve (rheumatic, bicuspid aortic valve, dysfunctional valve prosthesis), or by any congenital anomaly that causes flow turbulence (interventricular communication, obstructive hypertrophic cardiomyopathy, aortic coarctation).

The most common site of injury, and therefore the most frequent site of vegetation formation, is at the closing line of a valve, usually on the atrial surface of the atrioventricular valves or on the ventricular surface of the ventriculoarterial valves. With the endothelial lesion occurs the formation of a sterile thrombus, which can be colonized by bacteria that multiply there, turning the thrombus into vegetation. These vegetations are avascularized, making the treatment of endocarditis difficult due to the low access of antibiotics to microorganisms.
