Explanation:
the organ you speak of is the small intestine. the sm. intestine has fine cilia that absorbs all the nutrients consumed, then recycles nutrients to the bloodstream where RBC's carry nutrients to the rest of the body. I am not understanding what number u r talking about...
The lac operon is an operon required for the transport and metabolism of lactose in E.coli. When lactose is introduced to the increased medium, the lac genes are expressed due to the fact allolactose binds to the Lac repressor protein and maintains it from binding to the lac operator. Allolactose is an isomer of lactose. Small quantities of allolactose are shaped when lactose enters into E. coli. allolactose binds to the repressor protein and reasons the conformational change. As a result of this, the repressor can no longer bind to the operator area and falls off. RNA polymerase can then bind to the promoter and transcribe the lac genes. After some time, when the level of lactose decreases as it is metabolized using enzymes, it causes the synthesis of the repressor from the regulator gene. This repressor binds to the operator gene and prevents RNA polymerase from transcribing the operon and the transcription is stopped. This type of law is acknowledged as negative regulation.
Allolactose is a disaccharide comparable to lactose. It consists of the monosaccharides D-galactose and D-glucose linked thru a β1-6 glycosidic linkage alternatively of the β1-4 linkage of lactose. It may additionally occur from the occasional transglycosylation of lactose through β-galactosidase.

Answer:
When I make an ion in the simulation the simulation says – ion or + ion in the top right part of the simulation.
The ability to analyze DNA via DNA sequencing and other molecular analysis techniques has made it easier to group molecules into categories that represent lines of phylogeny.
Phylogeny is based on similar physical and genetic characteristics between organisms. Before such techniques, scientists were able to discern and group organisms only on the basis of their morphology, or their physical shape or appearance.
