Lymphocytes. Pathogens contain certain chemicals that are foreign to the body and are called antigens. Each lymphocyte carries a specific type of antibody-a protein that has a chemical 'fit' to a certain antigen.
Carpet vs. Laminate Flooring. When looking at flooring options, carpets and laminate floors are popular choices. Their cost is usually comparable and is cheaper than solid hardwood flooring. Roughly half of new flooring sold in America every year is carpet. Laminate flooring is considered more hygienic and hypoallergenic than carpet, as it is easily cleaned, and dirt won't go unnoticed.
Appearance and Aesthetics. In terms of aesthetics, the difference between hardwood and laminate floors is glaringly obvious. Real wood is characterized by tremendous texture variation of the wood grain, which is why no two planks of hardwood flooring, whether solid or engineered, appear exactly alike.
