I. Some species of insects and frogs are cryptically-coloured (Camouflaged).
II. Some animals are poisonous.
III. Some animals (e.g. monarch butterfly) are distasteful due to having certain chemical in their bodies.
The above adaptations are against

Options

A. Predation
B. Mimicry
C. Symbiosis
D. Protection

Answer

To solve the question regarding the adaptations of certain species against predation, we can break it down into clear steps:

### Step-by-Step Solution:

1. **Understanding Cryptic Coloration**:
- Some species of insects and frogs exhibit cryptic coloration, which helps them blend into their environment. This adaptation makes it difficult for predators to spot them, thus reducing the chances of being eaten.

2. **Identifying Poisonous Species**:
- Certain animals are poisonous, meaning they possess toxins that can harm or kill potential predators. This adaptation serves as a deterrent against predation, as predators learn to avoid these poisonous species after experiencing their harmful effects.

3. **Distastefulness in Animals**:
- Animals like the monarch butterfly are distasteful due to the presence of certain chemicals in their bodies. These chemicals are often acquired from their diet (e.g., feeding on poisonous plants during their larval stage). This adaptation signals to predators that consuming these animals will lead to an unpleasant experience, thus discouraging predation.

4. **Conclusion**:
- All these adaptations—cryptic coloration, being poisonous, and being distasteful—are primarily aimed at reducing the risk of predation. They help organisms avoid being eaten by predators, thus enhancing their survival.

### Final Answer:
The adaptations mentioned (cryptically-colored insects and frogs, poisonous animals, and distasteful animals like the monarch butterfly) are against **predation**.
