To define: The term immunity.
Introduction: The pathogen is an organism which causes infection and diseases to the host organism. These agents most often degrade the health of an individual. The responses that are generated towards these pathogens are from the immune system present in the body of an individual.
Explanation of Solution
The responses generated against the microorganisms for shielding an organism’s body is called immunity. Vaccination supports the immune system of an organism to develop resistance against a number of diseases. These vaccines may contain live attenuated (or weakened) antigens, killed antigens, subunit of the antigen or toxins of the pathogen.
Thus, the response generated against the microorganisms for shielding an organism’s body is known as immunity.
To explain: The meaning of memory and specificity of the immune system.
Introduction: The property of a body to fight against various disease causing microorganisms and generate an immune response is known as immunity. The small white blood cells which play a major role in immune system of the body are known as lymphocytes.
Explanation of Solution
When an infection occurred inside the body of an organism, the T cells transmit the signal to the B cells to produce antibodies against the antigens. The antibodies produced are highly specific to the pathogens present in the body. Those antibodies interact with the antigens and results in the death of the pathogen. The memory cells are generated in this process to store the information about the specific microbe to prevent the body from infections in the future.
Thus, the antibodies produced are highly specific to the pathogens present in the body and the memory of immune system stores the information about the previous encounter of microorganism to prevent the body from infections in the future.

- How is a protein destined for the Endoplasmic Reticulum (ER), imported into the ER? Be concise.arrow_forwardFind out about the organisations and the movements aimed at the conservation of our natural resources. Eg Chipko movement and Greenpeace. Make a project report on such an organisation.arrow_forwardWhat are biofertilizers and mention the significancearrow_forward
- PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans? Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.arrow_forwardOther than oil and alcohol, are there other liquids you could compare to water (that are liquid at room temperature)? How is water unique compared to these other liquids? What follow-up experiment would you like to do, and how would you relate it to your life?arrow_forwardSelection of Traits What adaptations do scavengers have for locating and feeding on prey?

- Competition Between Species What natural processes limit populations from growing too large? What are some resources organisms can compete over in their natural habitat?arrow_forwardSpecies Interactions Explain how predators, prey and scavengers interact. Explain whether predators and scavengers are necessary or beneficial for an ecosystem.arrow_forwardmagine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forward
