Choose some music with independent harmonies for your students to listen to. (There are some suggestions
below .) If you have the class time for it, and you have not already covered
monody ,
drones ,
chordal harmonies , and
parallel harmonies , you may want to include some examples of these for contrast. Suggested recordings for these other textures can be found in those lessons.)
Choose a song with independent harmonies for them to learn. Since this is fairly challenging, keep it simple unless you have older, musically trained students. If your students are up to the challenge, this type of harmony is not difficult to find; most SATB choral arrangements feature independent harmonies. If you would like a very simple example for young or musically inexperienced students, or if you are not experienced enough to tackle full-fledged harmonies, you may use "Train is a-Comin'", below. In this version, much of the song is in unison, with simple (but independent) harmonies in only a few places in the music. If you need to, listen to the
melody ,
higher harmony , and
lower harmony , and
all the parts together .
If you would like, arrange for an accompanist. An accompanist is not necessary for this style of singing (not even for a simple piece like "Train is a-Comin'"), but it may make things much easier or more comfortable for the singers.
Have enough copies of the words and music for the students.
Train is a-comin'
The notes in black are the melody. Red notes are an extensive high harmony; give this to a few students who are ready for a challenge. Blue notes are a very small low harmony part, which can be ignored if you like; if you have a few more students who can sing a few notes that are not in the melody, give this part to them. Everyone should sing the melody whenever they do not have a harmony part.
Procedure
Using the introduction
above as a guide, talk with the class about independent harmonies. Introduce any definitions you want them to learn, and contrast this musical texture with any other textures you have studied or will study, including
monody ,
drones ,
parallel harmonies ,
chordal harmonies , and
counterpoint .
Play some of your examples of music with independent harmonies or accompaniment. Ask the students to hum along with the melody the first time. Play the example again. Can they hum along with the bass line or another harmony or accompaniment part the second time? How different are the parts?
If you have them, play some of your examples of monody, drones, parallel harmony, chordal accompaniment, and counterpoint, for contrast. If you have also studied these other textures, identify them as they are listening to them.
If you have enough examples, play some more, asking the students to identify the pieces with independent harmonies. Can they identify the other textures as well?
Divide the students into higher and lower voices and assign appropriate parts for the song they will sing.
Teach each group its part (this may be done over the course of several sessions) and have them practice it alone before attempting to combine the groups.
The suggestions for recordings to look for are pretty vague because there is so much music in this category. It is very easy to find, so you should not spend a lot of time looking for specific recordings. Just make sure there is one clear and obvious melody in your selections, but that the accompaniment to it is interesting and independent of the melody. The choral selections will be more likely to be
homorhythmic , so that the words can be easily understood, whereas instrumental accompaniments will tend to be even more independent.
Suggested listening list
Almost any chorus from a Gilbert and Sullivan opera.
Recordings of choirs singing traditional (nineteenth-century) hymns.
If you have trouble hearing hymn harmonies, try listening to the chorales of Bach's
Christmas Oratorio (Weinachts Oratorium) . The chorales are not contrapuntal - the melody is clearly in the soprano part, and the different parts sing the same words at the same time - but it is unusually easy to hear that the parts are in fact quite different from each other.
Pop music with a solo singer, a strong bass line, and interesting instrumental accompaniment.
Most opera arias and many opera choruses.
This is also one of the most common
textures in orchestral music, particularly in classical-era and Romantic-era symphonies (Mozart, Haydn, Beethoven, Schubert, etc.) But be aware that in symphonic music, texture can change often and quickly.
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

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
