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.
C, it is the powerhouse of a cell
The potassium 40 to calcium or argon 40 half-life is 1.25 billion years so if this half-life is displayed then the age of 1.25 billion years would be valid. Half life is the time it takes for an isotope to decay into half its' amount and which in the process is losing its radioactivity.
