Question

50
___________ are specialized buds made to survive harsh conditions. (1 point)
spicules
gemmules
plankton
mesohyl
spongin

Explanation:

To solve this, we analyze each option:

• Spicules: Structural elements in sponges, not specialized buds for harsh conditions.
• Gemmules: Specialized asexual reproductive buds in sponges that can survive harsh conditions (like drought, extreme temperatures) and later develop into new sponges.
• Plankton: Organisms drifting in water, not specialized buds.
• Mesohyl: Gelatinous matrix in sponges, not a bud.
• Spongin: Protein in sponge skeletons, not a bud.

So the correct option is Gemmules.

Answer:

B. Gemmules
