Answer:

VEGETATION

Explanation:

It is referred to as an infected mass due to the production of bacteria in one heart valves. This infected mass can be due to bacteria in the bloodstream during any dental work, or any similar process related to bloodstream. This infected mass is called VEGETATION and related to endocarditis which is composed of fibrin and platelets.

Answer:

Vegetation.

Explanation:

The platelets are the thread like structures that plays an important role in the immune system of the body. Platelets helps in the blood clotting during the injury.

Vegetation may be defined as the the abnormal growth of the particular cells. This vegetation is often associated with the endocarditis. They mainly composed of the mass of the platelets and fibrin. This might affects the heart of the individual.

Thus, the answer is vegetation.

In an experiment, a certain colony of bacteria initially has a population of 50,000. A reading is taken every 2 hours, and at th

Iteru [2.4K]

Answer:

1) Recursive definition: $p_n = (50,000)3^n$

2) At the beginning of the 4th interval

Explanation:

1)

The initial population of the bacteria at time zero is

$p_0 = 50,000$

Here we are told that the reading is taken every two hours; we call this time interval "n", so

$n=2 h$

And also, after every time interval n, the number of bacteria has tripled.

This means that when n = 1,

$p_1 = 3 p_0$

And when n=2,

$p_2 = 3 p_1 = 3(3p_0)=9 p_0$

Applied recursively, we get

$p_n = 3^n p_0$

And substituting p0,

$p_n = (50,000)3^n$ (1)

2)

Here we want to find at the beginning of which interval there are

$p=1,350,000$

bacteria.

This means that we can rewrite eq.(1) as

$1,350,000=(50,000)3^n$

By simplifying,

$27=3^n$

Which means that

$n=3$

However, this means that the number of bacteria is 1,350,000 after 3 time intervals; therefore, at the beginning of the 4th interval.
