Ответ:
It would swell and then bust.
Explanation:
In a hypotonic solution, the water concentration of the cell's cytoplasm is lower than the concentration of the hypotonic solution. If a unicellular organism is exposed to a hypotonic solution, the water from the solution will enter gradually into the organism by the osmosis process. The aim is to keep a balance between water concentration on the inside and outside of the organism. But, that water that enters into the cytoplasm of the cell makes pressure on the cell membrane.
If the excess water cannot be removed from the organism, it will swell first and then, will burst.
Ответ:
Catabolite repression
Explanation:
Catabolite repression is characteristic for prokaryotic organisms such as bacteria and this is the way to control metabolism.
It is called repression, because enzymes that are involved in other sugar's metabolism are inhibited (repressed). The system of catabolite repression have components such as:
sensory systems-detects ratios of glycolytic intermediates,global regulators-control the expression of genes that encode for enzymes.
