Air pollutants
The poisonous atmosphere can be called air pollution, which refers to the presence of harmful substances in the air that can be detrimental to human health and the environment. This can include pollutants like particulate matter, carbon monoxide, sulfur dioxide, and nitrogen oxides.
1. Initial substances in a chemical reaction are called reactants.2. The obtained final substances are called products or resulting substances.
No, the substances at the start of a chemical reaction are called the reactants. They are transformed into different substances known as products through the course of the reaction.
Noxious substances released into the atmosphere can contribute to air pollution, which can have harmful effects on human health, ecosystems, and the environment. These substances can lead to respiratory issues, smog formation, acid rain, and ozone depletion. It is important to minimize the release of noxious pollutants to protect the quality of the atmosphere.
When substances mix but do not bond, it is called a mixture. In a mixture, the substances retain their individual properties and can be separated by physical means.
Foreign substances would suffice as well as contaminants, toxins, etc.

antibodies
antibodies
Antigens are protein substances formed in the blood to destroy foreign substances. Antigens can also be administered artificially in some cases.
The immune system reacts to foreign substances.
Antigens Antibodies neutralize these molecules.
Proteins that destroy foreign substances are called antibodies. Antibodies are produced by the immune system in response to the presence of antigens, such as bacteria and viruses, to help eliminate these foreign invaders from the body.
'Foreign' chemicals which get into the blood and provoke an immune response are called antigens.
antigens
Lysosomes use enzymes to break down cellular waste and foreign substances.
Cells called antigen-presenting cells, such as dendritic cells and macrophages, play a key role in activating the immune system when foreign substances appear. These cells identify and capture foreign antigens, present them to T cells, and help initiate an immune response.
