Match the descriptions to the processes. ice cream starts dripping down the sides of an ice cream cone. fog is created by using dry ice. frost forms on trees on a very cold day. the mirror gets fogged up when you breathe on it. your wet hair dries after a few minutes. liquid glass cools and hardens.

Ice cream melting is going from a solid to a liquid, therefore it is in the melting process. Fog by dry ice is a solid going directly to a gas, therefore it is in the sublimation process. Frost forming is gas to solid, therefore it is the process of deposition. The mirror getting fogged up is the process of condensation because it is a gas becoming a liquid. Hair drying is the process of vaporization because it is a liquid to gas. Liquid glass hardening is the process of freezing because it is a liquid to a solid shift.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
