Answer:
Pathogenic bacteria found in many hospitals are antibiotic resistant.
Explanation:
Antibiotics are chemical compounds able to kill or stop the growth of bacteria. Antibiotics are used as medicine to kill pathogenic bacteria within the human body.
Although antibiotics are designed to kill bacteria, bacteria evolve quite fast and it is very common to see how bacteria adapt and become resistant to antibiotics. This is a clear example of natural selection.
Natural selection is a process in which the best adapted individuals have greater of survival and passing their genetic traits on to the next generation. In relation to antibiotics, although they manage to kill many bacterial individuals, some few individulas survive, and they become resistant to that antibiotic. For this reason, the pharmaceutical industry is always trying to make more potent antibiotics.
The test that the nurse will need to check is the OXYGEN SATURATION TEST.
In an healthy lungs, the oxygen saturation level ranges between 95 and 100%, this means that, when red blood cells pass through the lungs 95 to 100% of them is saturated with oxygen. When a lung disease is present, this percentage will be highly reduced. Thus, the oxygen saturation test gives an indication of how efficient the patient's breathing is

A spacecraft that is not traveling at an orbital velocity will:
a. get attracted into a different kind of gravity or pole
b. will become off-set and be lost within space
This is the main reason why spacecrafts are well computed mathematically and engineering wise in order for it to travel and perform its roles in space.
The blackberry is an example of an aggregate fruit. These are made by the merger of several ovaries, while simple fruit is made by just one. Other fruits from this fruit type are raspberry and dewberry.
