Answer:false
Explanation:
A paper clip can become magnetic if it exposed to magnetic force that polarizes it
Explanation:
There are three ways heat is transferred into and through the atmosphere.
radiation. conduction. convection.
Radiation
Radiation is the transfer of heat energy through space by electromagnetic radiation.If you have stood in front of a fireplace or near a campfire, you have felt the heat transfer known as radiation. The side of your body nearest the fire warms, while your other side remains unaffected by the heat. Although you are surrounded by air, the air has nothing to do with this transfer of heat. Heat lamps, that keep food warm, work in the same way.
Conduction
Welding iron is transferring heat by conduction
Conduction is the transfer of heat energy from one substance to another or within a substance. Have you ever left a metal spoon in a pot of soup being heated on a stove? After a short time, the handle of the spoon will become hot.This is due to transfer of heat energy from molecule to molecule or from atom to atom. Also, when objects are welded together, the metal becomes hot (the orange-red glow) by the transfer of heat from an arc.
Convection
convection is the transfer of heat energy in a fluid. This type of heating is most commonly seen in the kitchen with a boiling liquid.
Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks. As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere. As it rises, the bubble cools with the heat contained in the bubble moving into the atmosphere

The cell-mediated immunity differs from humoral immunity in that they respond differently to invaders. The cell mediated immunity is a type of immune response that dose not involve antibodies, however it involves the activation of phagocytes, antigen specific cytotoxic T-lymphocytes, and the release of various cytokines in response to a foreign body (antigen). The humoral immune response is mediated by antibody molecules that are secreted by plasma cells.
