Question

a hydra is an aquatic organism that lives in fresh water. during reproduction an outgrowth begins to form on the parent. the outgrowth continues to develop into the daughter organism and eventually breaks off of the parent. which type of reproduction does this represent?

a. regeneration

b. budding

c. binary fission

d. vegetative propagation

Explanation:

To determine the type of reproduction, we analyze each option:

• Option A (regeneration): Involves regrowing lost body parts, not forming an outgrowth that becomes a new organism.
• Option B (budding): A new organism develops as an outgrowth (bud) on the parent, grows, and then detaches. This matches the Hydra's reproduction (outgrowth forms, develops, and breaks off).
• Option C (binary fission): The parent divides into two equal - sized daughter cells, common in bacteria/amoeba, not matching Hydra's outgrowth - based reproduction.
• Option D (vegetative propagation): Occurs in plants, using vegetative parts (like stems, roots) to produce new plants, not applicable to Hydra.

Answer:

B. budding
