Multiple choice

What is the term used to describe the process by which a marine parasite adapts to its host's immune system, allowing it to evade detection and attack?

  1. Immune evasion

  2. Immune suppression

  3. Immune tolerance

  4. Immune response
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Immune evasion is the process by which a marine parasite adapts to its host's immune system, allowing it to evade detection and attack. This can occur through various mechanisms, such as disguising itself as host tissue, suppressing the host's immune response, or rapidly changing its surface proteins.
