An E. coli colony grew on minimal medium supplemented with arginine and leucine. However, bacteria from this colony are unable t

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^+

When a potassium ion (K+) moves from the soil into the vacuole of a cell on the surface of a root, itmust pass through several c
goldfiish [28.3K]

Answer:

C. primary cell wall → plasma membrane → cytoplasm → vacuole.

Explanation:

Every molecule or particle which enters into a cell, it must pass through several cellular structure at different level means it also depends on the type of molecule like size, shape, and nature (characteristics). On the surface of root cell, potassium ion pass through the primary cell wall which is most outer layer of plant cell, then it passes the second layer called plasma membrane, in the plasma membrane cytoplasm is present and when potassium ion reaches the cytoplasm then it will enter into the vacuole present in cytoplasm.
