The various bacteria have different pathways to metabolise energy from molecules and therefor produce different molecules for aroma and taste. The main difference between the yeast and bacteria is that the latter propagates by cell division while the yeast spawns by budding. (The 2 yeast ...
The first really amazing form of carbon to be discovered is called buckminsterfullerene, after Buckmister Fuller the inventor and popularizer of many geodesic dome structures. Buckmisterfullerene is often referred to as "bucky balls" because it consists of molecules of 60 atoms in a graphite-like ...
either just for fun or a fun way of explaining diffusion or how a cell works (more on these later). Here I will show not only the setup of the original experiment that I saw, I will include the extra step that I did out of curiosity. So, here is a list of the things that I u...
There are additionally rare forms of chronic urticaria that are produced when the patient makes antibodies against molecules on the surface of their mast cells. There are tests available to identify this type of hive. Physical urticaria (for example, heat hives) is a type of chronic urticaria ...
This illustration, created by the Centers for Disease Control and Prevention, depicts the spiked structure of the virus that causes Covid-19 CDC Medical illustrators learn to locate and retrieve data on the structure of molecules from sites like theRCSB Protein Databank. They also use a host of...
Molar mass is the mass of one mole of a substance. A mole is defined as the number of atoms in 12 grams of thecarbon-12isotope. This is always a fixed number, known as Avogadro's number. Therefore, the molar mass of a substance is the mass of Avogadro's number molecules of that ...
are cost (practically free for the kitchen volcano; kits are inexpensive but still cost a bit more) and color (get richly-colored lava in a kit, which is harder to duplicate with a homemade volcano). No matter how you make it, a volcano is a fun project, great for kids of all ...
Kids love to make different shapes and figures on their bedroom walls. It's a fun project you can share with them. This may help when a child is afraid of the dark. A kind of weaning off the nightlight. A fun trick is to get or make a stencil, foot shaped or paw shaped and make...
It also involves an antibody or antigen (immunologic molecules). Human Immunodeficiency Virus (HIV) HIV (human immunodeficiency virus) is a sexually transmitted virus that attacks the immune system. If it is not treated, it can lead to AIDS (acquired immunodeficiency syndrome). Currently, there ...
Don't take my word for it; research it yourself. I have had the benefit of working in research and have seen what passes itself off as "science." Be warned. Byanon220298— On Oct 06, 2011 to 127. maltodextrin is a chain of glucose molecules and is absorbed as glucose. maltodextrin ...
