There’s no advantage but when ingested, the blood goes through a tract that's adapted for extracting nutrients because humans did not evolve such an iron-extracting mechanism, drinking blood can kill us.
Answer:
Concentration of sugar in the bag was higher than in the drink or higher concentration of water outside the bag or in the drink boiling tube so water moved in (to the tubing by osmosis.

The answer is - subculture.
The subculture is a group of people within a culture that differentiates itself from the parent culture to which it belongs, but it often maintains some of its founding principles. Subcultures develop their own norms and values regarding cultural, political and sexual matters.

Explanation:
The steps need to be arranged as follows:
1. S.aureus grow at low density on skin surface.
2. S.aureus enter tissue through a wound.
3. S.aureus grow to high density inside the tissue.
4. S.aureus sense quorum through only the Agr pathway.
5. S.aureus secrete toxin.
S.aureus is a bacterium which can be found in the normal flora of the body, however, under specific conditions, it can become pathogenic and cause skin and respiratory infections and food poisoning. Quorum sensing is a method used by bacteria for cell-to-cell communication and coordination of their colonization. Bacteria secrete signalling molecules to communicate and as the population grows so does the concentration of the signalling molecules. When the signalling molecules reach a specific concentration, then the expression of a specific gene is triggered. This gene is agr and it regulates the secretion of toxins which constitute the pathogenic mechanism of the bacterium.
