In this video, we are going to discover how to culture microorganisms on agar jelly in a petri dish. VISIT us at www.fuseschool.org, where all of our videos are carefully organised into topics and specific orders, and to see what else we have on offer. Comment, like and share with other learners.
From part 1, we discovered how to culture bacteria ensuring there is no contamination… in this video, we’re going to look at how we can calculate the size of our newly cultured populations. Click here to see more videos: https://alugha.com/FuseSchool VISIT us at www.fuseschool.org, where all of ou

In this video, KATHARINA KITZINGER explains that nitrification as carried out by marine microorganisms involves two distinct processes, with ammonia oxidation resulting in nitrite which is then transformed to nitra
A pathogen is a microorganism that can cause disease. Pathogens may be viruses, bacteria, protists or fungi. Examples of bacteria infections are cholera, typhoid, food poisoning and gonorrhoea. Examples of viral infections are the flu (influenza), measles, mumps, the common cold and AIDS. Some com
Human Defence Systems Against Pathogens | Health | Biology | FuseSchool Pathogens are disease causing microorganisms, that our body has many defence mechanisms against. The skin is the first physical barrier, providing a protective layer that is hard to penetrate. We also have sebaceous glands tha
How to use a Microscope | Cells | Biology | FuseSchool If you were alive 200 years ago you would have been given some very strange advice on how to avoid getting ill. You might have been told to carry sweet smelling flowers with you or avoid going to smelly places. This was because at that time peo

The advantage of organic fertilizer over mineral fertilizer is that it not only releases nutrients, it also helps improve soil structure and provides food for the microorganisms in the soil. Author: 3sat/NANO/Labo M/Anja Kollruß/Damaris Becker/Christian Gruber/Maximilian Mohr Translation and dubbi
Pathogens are disease causing microorganisms. They can be spread in many ways; by direct contact, by water or by air. Different pathogens are spread by different mechanisms. VISIT us at www.fuseschool.org, where all of our videos are carefully organised into topics and specific orders, and to se

What are viruses | Cells | Biology | FuseSchool In this video we are going to look at what viruses are. Viruses are a type of microorganism. They are too small to be seen with the naked eye: much smaller than bacteria, and about 100 times smaller than human cells. They come in many different shape
