Voices are as individual as faces; some altos will have a narrower or wider range, or the sweetest and most powerful part of their range in a different place than other altos. These are approximate, average ranges for each voice category.
Instrumental ranges
The same terms used to identify vocal ranges are also often used to identify particular instruments. For example a bass
trombone has a lower range than a tenor trombone, and an alto
saxophone sounds higher than a tenor saxophone. Some other terms that are used to describe instrument ranges are:
Contra – Means lower: for example a contrabassoon sounds lower than a regular
bassoon , and a contrabass clarinet is even lower than a bass clarinet.
Piccolo - Means higher (literally "smaller"): for example, a piccolo trumpet is higher than a regular trumpet.
A Note Name – If an instrument comes in several different sizes (and ranges), the name of a particular size of the instrument may be a note name: for example, an
F horn , a B flat
clarinet , and a C
trumpet . The note name is the name of the
fundamental harmonic of the instrument. An instrument with a slightly higher fundamental will have a slightly higher range; an instrument with a much lower fundamental will have a much lower range. Some instruments that are identified this way are
transposing instruments , but others are not.
The ranges of some instruments are definite and absolute. For example, even a beginning piano player can play the highest and lowest keys; and even the best player cannot play beyond these. But the ranges of many instruments are, like vocal ranges, not so definite. For example, an experienced horn or clarinet player can play much higher and lower notes than a beginner. An exceptional trumpet player may be able to play - with good sound and technique – high notes that the average high school trumpet player cannot play at all.
Other instruments may be a mix of absolute and indefinite ranges. For example, on any string instrument, nobody can play lower than the note that the lowest string is tuned to. But experienced players can easily play very high notes that inexperienced players have trouble playing well.
So it is sometimes useful to distinguish between a
possible range , which includes the notes that a very experienced player can get, and a
practical range , that includes all the notes that any competent player (including a good younger player) can get.
Outside of the instrument’s practical range, it may be a strain for even a very good player to play long or tricky passages. So if you are composing or arranging, it’s a very good idea to be able to distinguish between these two ranges for the voices or instruments you include.
Some sources even list the
power range of an instrument or voice. This is the part of the range where the instrument or voice is particularly strong. It may be in the middle of the range, or at the top or bottom, but writing in the power range should guarantee that the part is easy to play (or sing), sounds clear and strong, and can be easily heard, even when many other instruments are playing.
Thanks to everyone who participated in the survey! It was very useful to me, both as a researcher and as an author, to get a better picture of my readers' goals and needs. I hope to begin updating the
survey results module in April. I will also soon begin making some of the suggested additions, and emailed comments are still welcome as always.
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
