James is working with the lac operon of escherichia coli (e. coli). he places the bacteria on a plate of growth media. based on the current understanding of this operon, which hypothesis would be useful for james to test? addition of allolactose to the bacterial growth media should increase the speed at which the bacteria metabolize the sugar lactose. removal of the rna polymerase molecule should increase the amount of bacterial growth on the plate. addition of the fruit sugar, fructose, should inhibit bacterial growth. splicing the genes of the bacteria with other organisms should increase bacterial growth rates.

The correct answer is the first option.

"Addition of allolactose to the bacterial growth media should increase the speed at which the bacteria metabolize the sugar lactose."

Inclusion of allolactose to the bacterial growth media will mobilize lac operon, and by that there will be an increase in the speed at which the bacteria metabolize the sugar lactose

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

explanation:

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
