The Doppler Effect is a crucial concept for the MCAT, particularly in the Chemistry & Physics section. We'll explore how the Doppler effect occurs when a wave source moves relative to an observer, affecting the observed frequency and wavelength. Using practical examples like an a ...  Show more

In this episode, we cover the topic of viruses. We explore a comprehensive range of subtopics including the definition and structure of viruses, their life cycles, and the differences between transduction and transfection. We also discuss virus classification, viral mutations, an ...  Show more

Differences in ion concentrations inside and outside a cell cause a difference in the charge of the intracellular and extracellular environments. This electrical polarization of a cell relative to its environment is referred to as cellular membrane potential. This potential se ...

In this episode, Jamie explains the charges of sub-atomic particles — protons, neutrons, and electrons — and their role in making atoms neutral.

Discover how these charges balance in atoms, with protons and electrons contributing positive and negative charges, respecti ...

Melvyn Bragg and guests discuss an atomic particle that's become inseparable from modernity. JJ Thomson discovered the electron 125 years ago, so revealing that atoms, supposedly the smallest things, were made of even smaller things. He pictured them inside an atomic ball like a ...  Show more

In this episode, we discuss flame emission spectroscopy.Flame emission spectroscopy is an analytical technique used to determine the identity and amount of metal ions in a liquid sample. The process involves introducing the sample to a flame, which causes the metal ions to emit l ...  Show more
