What type of effects can toxicity cause?

Toxicity can lead to a range of effects on organisms, which includes acute effects, delayed effects, and allergic responses. Acute effects typically occur shortly after exposure to a toxic substance, presenting immediate symptoms or health issues. Delayed effects might manifest hours, days, or even later after the initial exposure, often resulting from the cumulative impact of the toxin on the body or from the activation of mechanisms that take time to develop. Allergic effects involve the immune system reacting to a substance, which can occur not only immediately upon exposure but also after a sensitization period where the immune system becomes familiar with the toxin.

This understanding highlights the multifaceted nature of toxic responses in organisms, reinforcing why recognizing all types of potential toxic effects is important for managing exposure and ensuring safety. The other options limit the scope by suggesting that only one type of effect occurs with toxicity, which does not accurately reflect the complexities involved in toxicological responses.
