the cell is unable to maintain a stable internal environment.
No, in a hypotonic solution, the solute concentration is lower outside the cell compared to inside the cell, so the transition is from a high concentration to a low concentration.
When the sodium ions are in higher concentration out side the cell, the cell shrinks. It does not expand and bursts. It can burst when the sodium ion concentration becomes very low, out side the cell.
The concentration of water in a hypotonic solution is relatively high. It is due to smaller amount of solute in the solvent.
Active transport is a process in which cells use energy to move substances against their concentration gradient, from an area of low concentration to an area of high concentration. This allows the cell to maintain specific concentrations of substances inside and outside the cell, which is important for various cellular functions.
A solution which has a high concentration of a solute (example - glucose) will have a low water concentration. But when you look at pure water it has a high water concentration. So if a cell contains a high concentration of glucose and was placed in a pure water solution, water would simply move down its concentration gradient (going from high to low) which eventually causes the cell to swell. I hope this helped :D

water moves from a high concentration to a low concentration in a cell

The concentration of the water determines the rate of diffusion. A higher concentration of water will be transported to an area with a lower concentration, via the concentration gradient. In a high salt solution, the concentration of the water is higher in the cell, and so the water is diffused through the cells semi-permeable membrane into the high salt solution, to try to stabilise the concentration differential.

a cell transports things across the cell membrane from areas of high concentration to ares of low concentration
water will move from a high H2O concentration inside the cell, to a low H2O concentration outside the cell.
Osmosis (when nutrients go from a high concentration of nutrients to a low concentration) and phagocytosis (when the cell actually eats it)
There are two basic ways that individual molecules can enter (or leave) a cell.1. Diffusion. This is the movement of particles from a region of high concentration to a region of low concentration. So if the concentration of the molecule is higher outside the cell it can enter by diffusion. However diffusion can only take place down a concentration gradient ie from a high to a low concentration.2. Active transport. This is the movement of particles against their concentration gradient (ie from a low to a high concentration), using energy provided by the cell (ie ATP produced by respiration). So if a molecule is at a higher concentration inside the cell it can only be absorbed by active transport.
The concentration on the solute goes from an area of high concentration to an area of low concentration
