Answer:
the genotype of the bacteria in this E.coli colony is arg^+leu^-met^+
Explanation:
The organism which, due to the lack of particular genes, can not synthesize a particular metabolite or nutrient by itself and needs the nutrient to the growing supplement is called auxotroph. The colony E.coli began to grow on a limited medium with arginine and leucine, and not with arginine and methionine in the above mentioned case. Leucine is therefore a vital metabolite required to grow bacteria and bacteria that do not contain the leu gene.
Therefore. the genotype of the bacteria in this E.coli colony is arg^+leu^-met^+
Answer:
condenser is placed below the stage and concentrates the light, providing bright, uniform illumination in the region of the object under observation. Typically, the condenser focuses the image of the light source directly onto the plane of the specimen, a technique called critical illumination. that is part of microscope which reflects light.
