Question

9 use the diagram below to answer the question. planarian hydra starfish all of the organisms above have a unique way of reproducing when part of their body is cut apart. which type of reproduction is being shown and what is an advantage of reproducing this way? (aks 7d) a this is asexual reproduction. an advantage of this type of reproduction is it a slow process which allows the organisms body to get all the parts replaced correctly. b this is asexual reproduction. an advantage of this type of reproduction is this process is quick and simple since it doesnt require a mate to reproduce. c this is sexual reproduction. an advantage of this type of reproduction is the resulting new organisms will be slightly different than the original, making them better to surv next time they are cut apart. d this is sexual reproduction. an advantage of this type of reproduction is the organisms dont need to find a mate to replace their body parts.

Explanation:

1. First, identify the type of reproduction: The organisms (Planarian, Hydra, Starfish) reproduce by fragmentation (a form of asexual reproduction) where a part of the body grows into a new organism, no mate is needed.
2. Analyze the options:

• Option A: Asexual reproduction's advantage is not being slow for replacement; it's quick. Eliminate A.
• Option B: Asexual reproduction (fragmentation) is quick and simple as it doesn't need a mate. This matches.
• Option C: This is not sexual reproduction (sexual needs two parents, these use one parent via fragmentation). Eliminate C.
• Option D: This is not sexual reproduction. Eliminate D.

Answer:

B. This is asexual reproduction. An advantage of this type of reproduction is this process is quick and simple since it doesn't require a mate to reproduce.
