This video explains what nanoparticles are and how their small size affects their physical and chemical properties, particularly in relation to their surface area-to-volume ratio. The video highlights potential applications of...

Paul Andersen explains how living organisms exchange matter with the environment. The importance of the surface area to volume ratio is emphasized using a simple mathematical model. The essential chemicals for life; water, carbon,...

This video explains the concept of efficient transport and exchange in organisms. It discusses the importance of exchanging substances with the environment, such as taking in oxygen and getting rid of waste. The video explains surface...

In this video, the concept of transport of substances into and out of cells is explained. The different ways in which this process occurs are discussed, including diffusion, osmosis, and active transport. The importance of surface area...

Explore the parts of the cell membrane with The Amoeba Sisters! Video discusses phospholipid bilayer, cholesterol, peripheral proteins, integral proteins, glycoproteins, and glycolipids - as well as why the surface area to volume ratio...

We use coloured agar cubes to see how different shapes change the rate of diffusion. The cubes are made using sodium hydroxide and phenolphthalein indicator to give them a pink colour. When these are added to hydrochloric acid, the...

In this video, we investigate how changing the linear dimensions of a three dimensional solid affects the volume and surface area. Specifically, how do we solve for missing values (like side length, volume and surface area) when we are...

In this video we have a look at the similarities and differences between prokaryotic and eukaryotic cells. All cells are either prokaryotic or eukaryotic. Organisms with prokaryotic cells are called prokaryotes, and organisms with...

What Is Adaptation? | Ecology & Environment | Biology | FuseSchool Learn about how organisms adapt to their habitats. "Adapting and Living Together" within the Ecology and Environment topic for school level biology. 00:00:06.560 --...

Camels are specially adapted for life in the desert. Their body shape and physiology has adapted to suit the harsh environment. Over thousands and thousands of years, the environment has put extreme selection pressures on camels, and...

In this video we have a look at the similarities and differences between prokaryotic and eukaryotic cells. All cells are either prokaryotic or eukaryotic. Organisms with prokaryotic cells are called prokaryotes, and organisms with...

Unicellular vs Multicellular | Cells | Biology | FuseSchool Did you know that some organisms exist of just one cell? These simple organisms, like amoeba, are unicellular. They depend on simple diffusion for life They are usually too...

Did you know that some organisms exist of just one cell? These simple organisms, like amoeba, are unicellular. They depend on simple diffusion for life They are usually too small to be visible to the naked eye, like bacteria, and so we...

The video discusses the factors that affect the rate of chemical reactions. The first factor is the number of collisions with enough energy to react. Other factors include changing the pressure, concentration, surface area, and...

The elephant is a creature of epic proportions -- and yet, it owes its enormity to more than 1,000 trillion microscopic cells. And on the epically small end of things, there are likely millions of unicellular species, yet there are very...

Could King Kong ever evolve to exist? Could we simply scale up a gorilla? How and where could this giant ape develop? Join us as we explore the science behind the king of monsters!

Imagine if it took a couple of months for the oxygen we breathed to reach our cells. Well, if we relied on diffusion alone for oxygen to get to the tips of our toes, it would take about this long. By this time, our cells would have died....
