Microbiology Question about Glucose medium?
if an organism grows in the OF-glucose medium that is exposed to air, is the organism oxidative or fermentative?
Suggestion by archaeadoc
The medium should change color if the organism can grow. If it grows on the presence of air only, then it is oxidative.
Here is another reference with pictures of the results

bacteria can grow on synthetic media.Can viruses be grown this way?Can viruses grow on cultures of bacteria?
Suggestion by Nicholas Summers
No, but they can be grown IN bacteria.
I think it’s pretty cool to think about.

Viruses can’t be grown on synthetic media (e.g. agar [a type of geletin]) but they can be grown on cultures of bacteria.
Think of how each reproduces:
Bacteria reproduce and live like any other living organism would, it takes in nutrients and reproduces using binary fission (like mitosis)
Viruses on the other hand are like little aliens. They really aren’t “living” since they don’t absorb nutrients or produce waste. Rather they hook onto another cell (e.g. a bacterium) and inject the cell with its own viral genetic code. This code then causes the cell to produce the multiple copies of the virus, essentially doing the reproduction for the virus at the cost of its own resources.
The virus can’t reproduce itself without another cell to “build” its copies. Therefore you can’t grow a virus on a synthetic media but you can grow it on a culture of other cells =)

Viruses must be grown on cellular media.
However, some viruses (bacteriophages) can be grown on cultures of bacteria. Bacteriophages, “phages”, infect and reproduce within bacteria.

PLEASE HELP ME!
Suggestion by Lena
Depends on what medium length means, depends on your hair texture, depends on your genes, depends on a lot of things, BUT! Hair, on average, grows an inch every two months.

so try this…regular trims are a must, about every 7-9 weeks.(if your hair is really healthy then up the trims to about every 12 weeks, a trim is just a snip off the ends) if its been awhile since you have had a trim then inches may be called for to get to healthy hair. i use vitamin e on fresh washed hair.(its a vitamin that can be purchased where you buy vitamins, cut open capsule, squeeze into hand, rub hands together and apply to hair) dont message into scalp. if you get too much then just rewash it. hair will feel slightly sticky until dry then it will be nice and soft. it tames the frizzies, deep conditions and makes hair grow about three in a month. it takes about a month for the growth part of the e to kick in. the other benefits are instant. dont brush your hair but maybe once a week to message the scalp, i use a wide tooth comb at other times. brushing breaks off hair. i just started biotin vitamins going on three months ago this sat and notice and big growth spurt from that. biotin is cheap and also promotes hair regrowth and growth. i also have the biotin shampoo that i got from a vitamin store online.(puritans pride.com or vitadigest.com) five bucks for a big bottle and a big bottle of E is about 8 bucks. the biotin is about 3 bucks. i now take my fingers and message my scalp about five times a week, along with the brushing thats a good way to do it without damaging your hair. apply two or three capsules of e to dry hair and message into scalp and hair really well, put damp towel in microwave for 1 min to get hot, then quickly wrap head, a dry towel can be placed over that to help hold in the heat, leave on for 15 min, shampoo well, makes an excellent hot oil treatment. good luck, AND some people will argue about regular trims, your hair does grow from the roots, yes, but if your hair is not trimmed at the bottom, the it splits, get dry and brittle not to mention thin looking from no trims at all and frizzy. then your hair starts to break off at the bottom and giving you the appearance that it never grows. so to make hair grow as fast as possible and keep it healthy, then trims are an essential part of hair care. look on a ruler and check out less then half an inch and if your salon does not know what that is then take a ruler with you, i have. as of this week im adding beta carotene vitamins to my regimen. i found out that along with the biotin it is very very good in promoting hair growth. they were five bucks for a bottle of 100. got them at walmart. the biotin and e can also be purchased at walmart, and adding all this up is pretty cheap to get great hair. i just wish the shampoo was available in the stores, but not yet.
Suggestion by StarsXHeartsX
Use hair products that promote healthy hair growth,like Garnier. It’s def possible to get it back to that length
