Long before a deeper understanding of their numerous biological functions, the plant lectins, also known as phytohemagglutinins, were noted for their particular high specificity for foreign glycoconjugates (e.g. those of fungi, invertebrates, and animals). and used in biomedicine for blood cell testing and in biochemistry for fractionation.
Electromagnetic energy is a term used to describe all the different kinds of energies released into space by stars such as the Sun. These kinds of energies include some that you will recognize and some that will sound strange. They include: Radio Waves. TV waves. Radar waves. Heat (infrared radiation) Light.
Light, microwaves, x-rays, and TV and radio transmissions are all kinds of electromagnetic waves. Different waves are made by their wavelengths. Electric fields are created by differences in voltage, the higher the voltage, the stronger will be the resultant field.lectromagnetic fields are found everywhere in nature, but are invisible to the human eye. There are also many human-made electromagnetic fields. An example of a human-made electromagnetic wave are X-Rays. There are many other types of waves that you can see on this website.
