What substances do T cells produce to destroy cells infected by a virus?
T cells produce cytokines, such as interferons and interleukins, that help enhance the immune response against virus-infected cells. They also release cytotoxic substances, like perforin and granzyme, which can directly kill infected cells. Additionally, T cells can activate other immune cells, like macrophages, to help eliminate virus-infected cells.
How does plastic destroy ozen layer?
Plastic does not directly destroy the ozone layer. However, when plastic is incinerated, it can release harmful chemicals into the atmosphere, such as chlorofluorocarbons (CFCs) which can deplete the ozone layer. Additionally, plastic pollution can indirectly contribute to ozone layer destruction by promoting climate change, which can affect the stability of the ozone layer.
What human-made chemicals cause the ozone to deplete?
Chlorofluorocarbons (CFCs), halons, and certain types of hydrochlorofluorocarbons (HCFCs) are human-made chemicals that cause ozone depletion. When these substances are released into the atmosphere, they break down and release chlorine and bromine atoms, which then destroy ozone molecules in the stratosphere.
What chemicals destroy teflon?
Perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) are known to degrade Teflon (polytetrafluoroethylene). Exposure to these chemicals at high temperatures or through prolonged use can break down the Teflon coating and release harmful gases.
What do white blood cells release to destroy pathogens?
Antibodies are released by B-lymphocytes (one of thekinds of white blood cells)
What are the release dates for The Encounter - 1999?
The Encounter - 1999 was released on: USA: May 1999
What is the function of each WBC?
Neutrophils: Phagocytize pathogens and release enzymes to destroy them. Eosinophils: Defend against parasites and regulate allergic reactions. Basophils: Release histamine and other mediators involved in inflammation and allergies. Lymphocytes: Coordinate immune responses, produce antibodies, and destroy infected cells. Monocytes: Phagocytize pathogens and debris, differentiate into macrophages in tissues.
What types of chemicals pollutants are responsible for the ozone depletion and where do these come from?
Chlorofluorocarbons (CFCs) and halons are the main chemicals responsible for ozone depletion. They are released from sources like refrigerants, solvents, and fire extinguishers. When these chemicals reach the stratosphere, they break down and release chlorine and bromine atoms that destroy ozone molecules.
What does eosinophil do?
Eosinophils release chemicals that destroy parasitic invaders and their eggs. They also engulf and destroy foreign cells like pollen, and animal dander.
