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.

g If a colony of bacteria starts with 1 bacterium and doubles in number every 20 ​minutes, how many bacteria will the colony con
Lynna [10]

Answer: 2.81 x 10∧14 baterias after 16 hours.

Explanation:

Hi, first we have to find how many 20 minute intervals are in 16 hours.

If 1 hour = 60 min, 16hours = 960 minutes (16 h x 60 min / 1 h)

If we divide the 960 minutes (16 hours) by 20 minutes we obtain 48. (960/48)

There are 48 twenty minutes intervals in 16 hours.

Now we have to apply the exponential growth formula:

P (t) = Po (1 +r) ∧t

Where:  

P (t) = population at time t  

P (0) = initial population (1)

r = growth rate (1)

t = time (48)

Replacing with the values given:

P (t) = 1 (1 + 1) ∧48= 2.81 x 10∧14

2.81 x 10∧14 baterias after 16 hours.

Irina18 [472]

Answer:

Read It and Understand

Explanation:

There are over 200 different cell types in the human body. Each type of cells is specialised to carry out a particular function, either solely, but usually by forming a particular tissue. Different tissues then combine and form specific organs, where the organ is like a factory where every type of cell has its own job.
