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^+
It is easy to launch the outer gas of the star so that it escapes from the star ! the final stage of the sun's life will be the ejection of the outer helium and hydrogen layers . These outer layers are hot and glow. The glowing hot ejected gases called a planetary nebula.
Answer:
C, a decrease in metabolic activity
Explanation:
Water is an essential compound needed for the survival of all organisms in nature.
The bulk of most organisms is made up of water. Most importantly, water is integral part of cellular metabolic processes.
- In the time of drought, metabolic activities will reduce.
- Organisms will tend to be inactive so as to conserve the little water they might have access to.
- This is an important adaption for organisms.
