What are the main ingredients of saltwater?
The ingredients in salt water are most commonly believed to be salt and water, although this is a bit of a myth, with no concrete scientific evidence.

What effect does salt water have on ice?
Fresh-water ice will melt faster in salt water than it will in fresh water or in the open air. Ice forms when water molecules are cooled down enough to arrange into solid crystals. Salt will, basically, get between the water molecules and make it harder for them to form crystals.
How do the material that makes water salty enter into the waterway?
The material that makes water salty is, you guessed it, salt! When various minerals are chemically weathered, they release there various constituents, and these then travel, dissolved in water, into the ocean. The water in the ocean then evaporates, rains, and flows back into the ocean loaded with more salt. The effect of this is to increase the concentration of salt in the ocean such that it seems "salty" to us.
Is salt and water a solution or a mixture?
Salt goes into solution in water. That makes a salt and water solution of salt water, unless there is too much salt to completely dissolve in the water. In that case, it will be a mixture of salt and salt water.Saltwater is technically both a solution and a mixture, since all solutions are mixtures, or physical rather than chemical combinations of substances. However, the more narrow use of the term "mixture" excludes both solutions and alloys.

Is Mannitol salt agar a selective or a differential medium?
Both
What reaction does the enzyme involved in Mannitol-salt agar test mediate?
Mannitol salt agar is selective for gram positive bacteria, and differential for mannitol fermenters. Phenol red is the indicator containing the enzyme mannitol.
Selective agent found in mannitol salt agar?
7.5% NaCl
What selective agent found in Mannitol Salt Agar?
The high salt concentration (7.5-10% w/v) makes the agar hard for all but staph spp. To grow, and staph aureus turns yellow when it ferments the mannitol.
Why can mannitol salt agar and EMB agar be described as both selective and differential media?
it is selective because only a salt tolerant can grow. 7.5 nacl it has diffrential properties also. if mannitol formentors turns yellow staphlococus aureus; but if it has no change then its a nonpathogenic staphlococci (s. edermis)
Which ingredient in mannitol salt agar supplies carbon?
mannitol is a type of sugar, so it supplies the carbon in the MSA medium
Purpose of high salt concentration in the mannitol salt agar medium?
Mannitol salt agar (MSA) contains high levels of salt because it inhibits the growth of most bacteria. This makes it an excellent medium to test for Staphylococci and Micrococcaceae as they are tolerant of high levels of NaCl.
Why is mannitol salt considered to be a differential media?
Mannitol salt agar is used for the isolation of staphylococci which is found normally on skin (S. aureus). The selectivity is obtained by the high salt concentration that inhibits growth of many groups of bacteria.
HOW do mannitol salt hook up to glycolysis?
Mannitol is not a substrate for glycolisis
Does bacillus subtilis ferment acid from mannitol salt agar?
In my result i isolate bacillus sp on mannitol salt agar but i expect that this media has deoration or expaired
Why is Msa argar a selective medium?
Mannitol Salt Agar is selective for staphylococci as the high salt (sodium chloride) levels prohibit most other bacteria from surviving and it is differential as Staphylococci ferment mannitol, producing acid, lowering the pH and turning the media yellow. The development of yellow media presumes the bacteria to be pathogenic Staphylococcus (usually S. aureus). From A Photographic Atlas for the Microbiology Laboratory by Leboffe and Pierce.
How do mannitol-salt agar tests work?
Mannitol salt agar supports growth of organisms that can grow in a high salt concentration, particularly Staphylococcus species and halophiles. The phenol red pH indicator in the agar will also let you know whether or not the bacterium you streaked ferments mannitol by changing to a yellow color if fermentation has occured.
