The reason why red blood cells were not seen in the sample where they were suspended in sterile water. Concept introduction: Osmosis occurs when water is transported by fluids across a semi-permeable membrane down the concentration gradient. This process takes place in accordance with temperature, and pressure. If the concentration of solute and free water molecules is same, the solution is isotonic and doesn’t involve any movement of water across the semi-permeable membrane. When a solution with varying concentrations is divided by a semi-permeable membrane, a solution that contains higher concentration is calledit as a hypertonic solution and that is more diluted is called isotonic solution.

The consequence of suspending bacterial cells in sterile water.

Concept introduction:

If the concentration of solute and free water molecules is same, the solution is isotonic, and it does not involve any movement of water across the cell membrane by osmosis. When a solution with varying concentrations is divided by a membrane, the area with higher concentration is the hypertonic solution and the area which is more diluted is called as the isotonic solution. Osmosis always occurs down the concentration gradient (from low concentration to high concentration).

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
