These substances are called products.
White blood cells, specifically lymphocytes, are responsible for helping to fight invading antigens in the blood. These cells produce antibodies that target and neutralize foreign substances, such as bacteria or viruses. Additionally, white blood cells can mount an immune response to destroy these antigens and prevent infection.
These substances are called in the English terminology products.
This is a homogeneous solution.
This is called a compound.
The process by which food substances are chemically changed into simpler forms that can be absorbed is called digestion. This process involves the breakdown of complex molecules into smaller molecules that can be transported and utilized by the body for energy and nutrition.
Introduction of altered antigens involves exposing the immune system to modified versions of antigens to trigger an immune response without causing disease. This approach can be used in vaccine development to stimulate immune memory and protection against specific pathogens or diseases. Altered antigens can include weakened or inactivated forms of pathogens, as well as genetically engineered antigens.
Physically blending substances involves mixing them together without changing their chemical composition. In contrast, chemically combining substances involves a chemical reaction that forms new substances with different properties.
With the usual meaning of "ice" and "steam", both are forms of water.Note that you can also call frozen forms of substances other than water "ice"; similarly, gaseous forms of substances other than water may also be called "steam".
Each atom can exist in many forms on its own. Then when you combine each of the forms with each of the forms of the other atoms, the number of substances increases exponentially.
