When an organism can tolerate specific chemicals meant to kill it, it is said that the organism has developed a(n) ______________________ to the chemical.

Answers

Answer:

Immunity.

Explanation:

The organism has developed an immunity to the chemicals meant to kill it. An immunity allows the organism to not be effected anymore by it and survive.

Hope this is correct, have a great day!

When an organism can tolerate specific chemicals meant to kill it, it is said that the organism has developed an Immunity to the chemical.

What is meant by the term Immunity ?

Immunity pertains to an individual body’s ability to restrict the incursion of pathogens. Pathogens are foreign disease-generating substances, which includes bacteria and viruses, and humans are susceptible to them on a daily basis.

Antigens are attached to the surface of pathogens which further arouses an immune response in the body of an individual. Immune response or immunity refers to the body’s capability to defend and to fight against antigens and protect the body.

There are various types of immunity, which consists of innate immunity, passive immunity, and acquired/active immunity.\

1) Innate immunity refers to standard protection that a person is born with already acquired since birth, consisting physical barriers (skin, body hair), defense mechanisms (saliva, gastric acid), and generic immune reactions (inflammation).

2) Passive immunity refers to an individual body’s ability to resist pathogens by “borrowing” antibodies. For illustration, antibodies could be transmitted to a baby from a mother’s breast milk, or via blood products consisting antibodies like immunoglobulin that can be diffused from one person to another.

Thus, when an organism can tolerate specific chemicals meant to kill it, it is said that the organism has developed an Immunity to the chemical.

When they get to the end of the neuron, a chemical called neurotransmitters are released which travels across the cells and send it to the brain, the brain then process it and interprete the signals and respond to it as stimulus.
