Explain unique features of acquired immunity.
Show Hint
Solution and Explanation
Distinct Characteristics of Acquired Immunity: Acquired immunity refers to the adaptive and specific immune response that builds up over time.
1. Specificity: Precisely targets pathogens by recognizing specific antigens.
2. Memory: Develops memory cells that expedite the immune response during subsequent infections.
3. Self vs. Non-Self Recognition: Effectively differentiates between the body’s own cells and foreign entities.
4. Diversity: Capable of recognizing a vast array of different antigens.

- If \( x = f(t) \) and \( y = g(t) \) are differentiable functions of \( t \), so that \( y \) is a function of \( x \) and \( \frac{dx}{dt} \neq 0 \), then prove that: \[ \frac{dy}{dx} = \frac{\frac{dy}{dt}}{\frac{dx}{dt}}. \] Hence find \( \frac{dy}{dx} \), if \( x = at^2 \), \( y = 2at \).
