A leg is a limb, it is neither positive or negative.
urease negative
gram positive..
Neither, only bacteria are classified as Gram positive or Gram negative.
Negative. There are VERY few positive feedback mechanisms in the body- the only one i know about is birth. Think of negative feedback and positive as a line.
Streptobacillus is a gram negative, oxidase negative, catalase negative, non motile organism, and 0.3-0.7 µm by 1-5 µm in lengthEscherichia coliMost of the Enterobacteriaceae are Catalase Positive. E. coli is Catalase Positive and Oxidase Negative. Do not report the previous as an answer. For gram negative, catalase negative and oxidase negative rods, it is likely that you have bacteria of the Bacteroides genus.
the negative leg is shorter than the positive leg.
On an LED, one leg will be shorter than the other. The shorter leg is the negative polarity.
Anode and cathode. Anode = negative lead, cathode = positive lead.
Cathode (negative) is the shortest leg and there is a flat edge on the base of the LED, and it must be connected to the negative wire or "-" connection. Anode (positive) is the longest leg, and must be connected to the positive wire or "+" connection, as electricity will only pass through a LED from positive to negative.
L.E.D has one leg longer then the other one, the longer one is positive and the smaller one is negative. If you have a l.e.d which has same length of legs then look inside the l.e.d for two kind of triangle peices and one of them will be smaller which is positive and one which is bigger and is negative.
The positive lead is marked with a red dot or a + symbol.
Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative
Negative * positive = negative Positive * positive = positive Negative * negative = positive
The rules for the sign (positive or negative) of the result of a multiplication is the same as division. For multiplication: Positive * Positive --> Positive Positive * Negative --> Negative Negative * Positive --> Negative Negative * Negative --> Positive For division: Positive / Positive --> Positive Positive / Negative --> Negative Negative / Positive --> Negative Negative / Negative --> Positive
Current will only flow one way through an LED, so it has a positive leg and a negative leg. One of them is longer to signify which is which (longer is negative). The negative side also has a chamfered edge on the LED itself.
Yes. Negative/negative = positive Postive/Positive = positive Negative/Positive - negative
Negative * positive = negative Positive * positive = positive Negative * negative = positive
