An advantage of negative supercoiling in bacteria is that Multiple Choice it promotes strand separation in small regions enhancing DNA replication and transcription. it induces the DNA to form alternative structures which inhibit DNA replication and transcription. it promotes strand separation in small regions enhancing crossing over. it promotes strand separation in small regions enhancing the wrapping of DNA around histone proteins. it promotes the splicing of exons and removal of introns.

sex cells are usually half's then they find another half and make a fertilize egg

answer;

a. sheep consumption efficiency would be reduced.

explanation;

-trophic efficiency is a measure of how much energy occurs at one level divided by the energy at the level immediately below it . trophic efficiency incorporates three types of efficiency:

-the proportion of available energy that is consumed (consumption efficiency).   it is the proportion of the available biomass that is ingested by consumers.

-the proportion of ingested food that is assimilated (assimilation efficiency).

-the proportion of assimilated food that goes into new consumer biomass (production efficiency).

-in this case, the grasshoppers would affect sheep by reducing the proportion of the available biomass that is ingested by the sheep.
