Clip 7 Diffusion - ScienceIn this video, we look at diffusion. I provide information on diffusion and cell membranes; as well as that I provide information on how diffusion happens in both solutions and gases. I also include the details on what affects the rate of diffusion; for instance, a higher temperature will also give a faster diffusion rate because the particles have more kinetic energy, so the particles are more likely to collide with one another; with enough energy.
Clip 5 Chromosomes and mitosis - ScienceIn this video, we look at chromosomes and mitosis. I provide information about chromosomes and mitosis; and as well as that, I explain the two main stages of the cell cycle. I also explain how body cells in multicellular organisms divide to produce new cells as part of a series of stages called the cell cycle.
