This is a classic "picture frame" resolving forces question. By resolving horizontally we can use the "assuming the particle remains stationary" meaning the forces must cancel...

The alveolar epithelium is a site of rapid diffusion, consequently it is very thin, only one cell thick, providing a short diffusion pathway.Alveoli have constant blood flow and ventilation, maintaining a...

Transpiration of water through stomata creates low potential at the top of the xylem. Water molecules stick together via hydrogen bonds in a process known as COHESION. This occurs because...

Consider a single photon (a particle of light) of a particular energy striking the surface of a metal. If the energy of this photon exceeds the work function of the metal, it will remove a single electron...

Firstly, ligands are an atom, molecule or ion which can donate a electron pair (lone electron pair). In a diagram, we would show this donation of a lone electron pair to a central metal ion by using a arr...
