Answer: b and e
Explanation:
Two solutions are isotonic to each other if the have the same osmotic pressure.
Since the cell is impermeable to sucrose, sodium and chloride ion outside the cell, For the solution inside the cell to be isoosmotic to the solution outside the cell, same 1M of sucrose should be added to the solution inside the cell to balance osmotic pressure.
If osmolarity is the concentration of a solution expressed as the total number of moles per litre, also the addition of an ionic 0.5M Na+Cl- to the solution inside the cell will also balance the osmotic pressure.
0.5M if NaCl will dissociate and create an equivalent 1M osmotic pressure inside the cell.
B. 2
Two concepts being tested here – the pattern of distribution of electrons and the octet rule.<span> </span>
Answer:
cell theory states that: all living things are composed of one or more cells, the cell is the basic unit of life, and new cells arise from existing cells.
I hope this helps :)
