Answer:
The cell would lose the water inside it causing it to die.
Explanation:
Water in cells moves towards the higher concentration of salt so if there is more on the outside the water would move on the outside causing it to die because it needs water. If it was the opposite and there was more salt inside more water would go inside causing the cell to swell and virtually exploding and diluting parts of our body.
The bacterium is not susceptible to the penicillin family of antibiotics. it contains no plasmids and relatively little peptidoglycan. Adherence to the intestinal lining by this bacterium is due to its possession of a capsule.
Answer;
-Sodium
Because Andy has high blood pressure and heart disease, he must lower his intake of Sodium.
Explanation;
-Eating substances rich in sodium such as salt raises the amount of sodium in the bloodstream and wrecks the delicate balance, reducing the ability of the kidneys to remove the water.The result is a higher blood pressure due to the extra fluid and extra strain on the delicate blood vessels leading to the kidneys.
-Therefore, for an individual with high blood pressure and heart disease like the case of Andy, he or she must lower the intake of sodium.
You have to have both the pL promoter as well as a second system of the cI repressor which controls the pL promoter.
When the cI repressor is expressed it will bind onto the operator region of the pL promoter and prevent expression.
When the cI repressor is not expressed it can't bind to its operator and the pL promoter (which is very strong) can express whatever gene it is upstream of.
So you need to have both for transcriptional control. you don't need the rest of the phage!
