To help understand diffusion of water, try to imagine a high and a low water concentration e.g. a 20% salt solution (A) must be 20% salt and 80% water and a 5% salt solution (B) must be 5% salt and 95% water. So we can think of solution A as having a lower water concentration and solution B as havin ...

Regulation of Gene Expression
... The regulation of gene expression conserves energy and space. It would require a signi cant amount of energy for an organism to express every gene at all times, so it is more energy e cient to turn on the genes only when they are required. In addition, only expressing a subset of genes in each cell ...

Signal transduction
Signal transduction occurs when an extracellular signaling molecule activates a specific receptor located on the cell surface or inside the cell. In turn, this receptor triggers a biochemical chain of events inside the cell, creating a response. Depending on the cell, the response alters the cell's metabolism, shape, gene expression, or ability to divide. The signal can be amplified at any step. Thus, one signaling molecule can cause many responses.
