An adaptation is a characteristic which helps an organism to survive in its environment. Plants and animals must adapt so they can compete for resources and live successfully in their habitat Some adaptations can help organisms to not get eaten hide control body temperature or prevent water loss an adaptation gives an organism a better
In this video you will learn how condensation polymers form, some examples of condensation polymers and the uses of these polymers. Unlike addition polymers where monomers react to form a single product, in a condensation polymerization reaction not only is the polymer formed but also a small molecule is eliminated or lost, normally water. Polyesters
In this video, you will learn the some of the chemical properties of alcohols, how to classify alcohols and some uses of alcohols. Alcohols are organic molecules with the hydroxyl functional group, which is an oxygen bonded to a hydrogen OH. Here is methane – replace a hydrogen with the alcohol functional group to form
Hi, guys. Just introducing my IGCSE EDEXCEL chemistry video. It’s all-in-one. Hope you find it helpful. The timings for all the topics are in the description box below, so if you’re not keen on watching the whole thing in one, you can skip ahead there. As always, I have written perfect answers all the way
Hi, guys, and welcome to my all-in-one IGCSE Edexcel Biology video (9-1). This much-requested video is finally here. I’m going to take you through, hopefully, every single spec point so that by time you’ve watched it, you can feel really confident about getting that grade 9. Don’t forget my revision guides. I sell these online.
