An explanation and picture of the frequency allocation chart.
To prevent radio stations from transmitting signals “on top of
each other,” the United States and other national governmentsin the 1930s began regulating the carrier frequencies and power
outputs stations could use. With increased use of the radiospectrum for both public and private use, this regulation has
become increasingly important. This is the so-called
Frequency Allocation Chart , which shows what kinds
of broadcasting can occur in which frequency bands. Detailedradio carrier frequency assignments are much too detailed to
present here.
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments

But not all bacteria make spores, l mean Eukaryotic cells have Mitochondria which acts as powerhouse for them, since bacteria don't have it, what is the substitution for it?
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
There are nothing like emergency disease but there are some common medical emergency which can occur simultaneously like Bleeding,heart attack,Breathing difficulties,severe pain heart stock.Hope you will get my point .Have a nice day ❣️

define infection ,prevention and control
Innocent
I think infection prevention and control is the avoidance of all things we do that gives out break of infections and promotion of health practices that promote life
