The cascade amplifies the signal.
Explanation:
The purpose of the cascade is to transmit a signal to other components in the shortest time possible and do it massively, so when a receptor is activated, this affects a high number of receptors. By doing a cascade reaction, the information travels very fast, achieving the objective quickly, and without a significant loss of energy, in other words, is an efficient method.
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Also Humans may destroy natural landscapes as they mine resources and urbanize areas. This is detrimental, as it displaces residing species, reducing available habitats and food sources. ... This can negatively effect an ecosystem because the introduced species may outcompete native organisms and displace them.
Answer:
A polio antigen
Explanation:
<em>The substance in the polio vaccine that makes it effective in the mitigation of the disease is the polio antigen.</em>
<u>An antigen is any substance that is capable of eliciting an immune response in an individual through the production of antibodies.</u>
Antigens could be of two types;
- foreign or hetero antigens
- self or auto antigens
Foreign antigens are those whose sources are from outside of the body while self antigens are those within the body, a characteristic of people with auto-immune diseases.
The polio vaccine contains polio antigens which is an inactivated or weakened form of the pathogen responsible for causing the polio disease.
