The correct Answer is:
To solve the question "The immunity associated with memory is called," we can follow these steps: ### Step 1: Understand the Types of Immunity First, we need to identify the different types of immunity that exist. The main types are: - **Innate Immunity**: This is the natural defense system we are born with, which does not have memory. - **Acquired Immunity**: This immunity develops after exposure to a pathogen and is associated with memory. - **Passive Immunity**: This is immunity gained through the transfer of antibodies from another source, such as maternal antibodies. - **Natural Immunity**: This is a type of acquired immunity that occurs when a person is exposed to a pathogen naturally. ### Step 2: Identify the Key Concept of Memory in Immunity The question specifically asks about immunity that is associated with memory. This is a crucial point because: - Memory cells are responsible for the long-lasting immunity that develops after the first encounter with a pathogen. ### Step 3: Analyze the Options Now, we can analyze the options based on our understanding: - **Innate Immunity**: Incorrect, as it does not involve memory. - **Acquired Immunity**: Correct, as it involves memory cells that remember past infections. - **Passive Immunity**: Incorrect, as it does not involve the body’s own memory but rather the transfer of antibodies. - **Natural Immunity**: While it involves a primary response, it is not specifically termed as memory-associated immunity. ### Step 4: Conclusion Based on the analysis, the immunity associated with memory is called **Acquired Immunity**. ### Final Answer **Acquired Immunity** ---
