The evolutionary advantage that would be there to the formation of a pellicle in a liquid medium by a bacterium is they could form colonies and have a greater chance of survival. Two ways to determine motility of a bacteria is using a agar deep or the hanging drop technique.
Look at where the pellicle forms. Usually it is on the surface (where the bacteria grows better because of easier access to the oxygen in the atmosphere or somewhere the water is moving so new nutrients are continually passing by to be eaten.
Crude oil comes from these remains but it takes a very long time for them to form.
Minerals seeping into an organisms remains form fossils. sediment
ammonia
all solutions consists of solute and solvents and solvents are always in liquid form. some may come in an emulsion form though, but still it can be considered as liquid .
yes it would because when the liquid boils the entire container of liquid is heated to the boiling point, meaning that the liquid would turn to the vapor form all around the liquid.
in pellicle formation small masses of cells gather at the top of the nutrient broth. these organisms (masses of cells) are aerobes. the oxgen concentration is greatest at the top which would explain growth of the pellicle type.
The nutreint media which reamin in liquid form through out the culturing process is called liquid media. It is different to solid media in not having agar in it which is the solidifying agent used in medium prepration. Commonly prepare liquid media is nutrient broth which contain beef extract, partially digest protein (peptones) and sodium chloride.
Media = medium
You should use an inoculation needle for making smears from a solid media so you can control how much specimen is put onto a slide. This method is easier for solid media and you would use a loop for liquid media.
Crude oil comes from these remains but it takes a very long time for them to form.
No, media is the plural form of medium.
The plural form of liquid is liquids.
Crude oil comes from these remains but it takes a very long time for them to form.
A pellicle is the membrane that envelops a euglena. An euglena is best known and most widely studied member of the phylum Euglenophyta.
The word 'media' is the plural form for the singular noun medium. The plural possessive form is media's.The media's coverage of the storm was adequate to excessive.
what is the irregular word form for media
Television is the most widely used form of mass media.
