✅ Yesterday's Answer: C. Cnidaria 🪼
📖 Explanation:
Hydra belongs to the phylum Cnidaria, a group of aquatic animals that possess cnidoblasts (stinging cells) used for capturing prey and defense. Most cnidarians show radial symmetry and have a single opening that serves as both the mouth and anus.
🧠 Quick Memory Trick:
👉 "Cnidaria = Cnido = Needle" 🪡
Remember Cnidaria by thinking of stinging needles, because all cnidarians have cnidoblasts (stinging cells).
🌊 Examples: Hydra • Jellyfish • Sea Anemone • Coral

✅ Yesterday's Answer: C. Chitinous Exoskeleton 🦀
📖 Explanation:
Arthropods have a hard chitinous exoskeleton, which acts as an external protective covering. This exoskeleton provides support, prevents water loss, and protects the body from predators and environmental damage. Since it cannot grow with the animal, arthropods periodically shed it through a process called molting (ecdysis).
🧠 Quick Memory Trick:
👉 "Arthro + Chitin = Tough Outer Cover!"
Think of Crab = Chitin = Exoskeleton.
🌟 Examples of Arthropods:
🦀 Crab • 🦋 Butterfly • 🕷 Spider • 🦐 Prawn • 🐜 Ant • 🪳 Cockroach
