Question

a planarian is a type of multicellular organism. a process that occurs in a planarian is represented in the model below. select one word or phrase in each set of parentheses to best describe this process. the model represents the process of ( budding / regeneration / vegetative propagation ). this process is a type of ( asexual / sexual ) reproduction that is most similar to ( meiosis / mitosis ). the two organisms that result from this process contain dna that is ( identical / different ).

Explanation:

1. Planarians are known for their ability to regenerate. Regeneration is the process where a part of the organism is able to grow into a complete organism again. Budding involves an out - growth from the parent organism, and vegetative propagation is mainly in plants.
2. Regeneration in planarians is a form of asexual reproduction as it does not involve the fusion of gametes. Mitosis is the type of cell division involved in asexual reproduction and growth of somatic cells, while meiosis is for sexual reproduction to produce gametes.
3. Since it is asexual reproduction via mitosis, the DNA in the resulting organisms is identical to the parent organism's DNA.

Answer:

1. regeneration
2. asexual; mitosis
3. identical
