The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies.
Explanation:
Specific immune responses are triggered by antigens. Antigens are usually found on the surface of pathogens and are unique to that particular pathogen. The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies.

Answer:
Higher biodiversity seems to be associated with a better response to disturbance events
Explanation:
Biodiversity means 'the variety of life'. Disturbance processes modify the environment and also affect demographic processes such as growth, recruitment, survivorship, etc., thereby producing changes in biodiversity. In an ecosystem, biodiversity contributes to its sustainability. In this regard, it has been shown that disturbance events are less important in species-rich ecosystems such as tropical wet forests compared to less rich ones (such as dry forests). The communities with higher biodiversity levels are known to be more productive in terms of biomass, and thus they seem to be more stable (and successful) to disturbance events.
