Frizzled (Fz)/planar cell polarity (PCP) signalling is a conserved mechanism regulating the polarity of cells along the axes of a tissue. Fz/PCP regulates a diverse array of processes including ...

Water molecules are so attracted to each other that even after the balloon pops, the water molecules stay together keeping the shape of the balloon. In the water molecule, the oxygen and hydrogen ...

Dizzying though this may seem, life is always in motion, right down to its fundamental building blocks — molecules. Molecules can be thought of as atoms that share electrons. They form ...

Students investigate the polarity of the water molecule and design tests to compare water to less polar liquids for evaporation rate, surface tension, and ability to dissolve certain substances.

From growth hormones to cancer drugs, small molecules play a crucial role in our health. Monitoring them is essential to keeping us healthy; it enables physicians to calculate dosages and patients to ...

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...
