The answer is The ions are protected inside the lipid bilayer so that it is not pushed back to a more polar environment.
The lipid bilayer is mainly composed of lipids (phospholipids and cholesterol), and is also composed of proteins such as transporters.
The ions (which are polar) can not cross directly through the lipids because they will repel them due to their apolarity. On the other hand they can easily pass through protein channels that will protect them during their passage (the proteins are more polar than lipids).
Answer:
A. The number of cells that are dying is balanced by the number of new cells that are being formed.
C. Harmful waste products may be accumulating.
D. The cells are likely running out of nutrients.
Explanation:
During the stationary phase, the number of viable cells remains constant. This may be due to a balance between cell division and cell death wherein the total number of newly formed cells and the cells undergoing death are equal.
Nutrient limitation is one of the several factors that make the microbial cells to enter the stationary phase. Depletion of nutrients slows down the population growth.
Accumulation of toxic waste products as it occurs during the growth of anaerobic bacteria also adversely affects the population growth.
For example, the accumulation of lactic acid and other organic acids (by-products of anaerobic respiration) inhibits the growth of the population by making the medium acidic.
