A researcher claims that different metabolic pathways allow bacteria to use different molecules as sources of matter and energy.
Which of the following statements best helps justify the researcher’s claim by providing a relevant example?a.Rhizobia bacteria form close associations with the roots of bean plants.b. coli bacteria reproduce in liquid media containing either glucose or galactose.c.The antibiotic rifampicin inhibits the growth of some bacterial strains but not of others.d. Some viruses that infect bacteria reproduce by either the lysogenic cycle or the lytic cycle.
E.coli has a preference of glucose over other energy molecules and therefore whenever glucose it present, it leaves no chance of metabolizing and using it as a source of energy.
However, in absence of glucose E.coli uses alternative energy sources such as galactose, maltose, lactose, arabinose etc. Therefore, it is clear that in order to sustain, an organism or bacteria follows multiple metabolic pathways to derive energy from various energy sources.
The visible bodies of water are referred to as surface water. The majority of fresh water is actually found underground as soil moisture and in aquifers. Groundwater can feed the streams, which is why a river can keep flowing even when there has been no precipitation.
It would be easier to see the data in a line graph. This way, you could easily see the growth of mass and the (i'm guessing height?) of the AWM in relation to the time (aka week). The bar graph could work, but a line graph would be a better option for this information.
The first statement is correct. This is because plants transfer light (which is absorbed by chlorophyll) to chemical energy to convert carbon dioxide and water into glucose and oxygen.
