Question

You wish to study the impact of synthetic estrogen like hormones on the health of whales (and people). Select the organism from the table below that would be best to use in your research. Why did you select this organism?

Model Organism Characteristics

Yeast------------------Single celled, eukaryotic (contains a nucleus)
Fruit fly---------------Multicellular, eukaryotic, invertebrate, arthropod
Zebrafish-------------Multicellular, eukaryotic, vertebrate, fish
Mouse-----------------Multicellular, eukaryotic, vertebrate, mammal


Fruit flies, because they are multicellular like whales
Mouse, because they are mammals like whales
Yeast, because they are eukaryotic like whales
Zebrafish, because they live in the water like whales

Answer 1

The answer is a mouse

Answer 2

Because humans are multicellular, eukaryotic (contains a nucleus), vertebrates, and mammals, the best organism to test the synthetic hormones on would be a mouse.

Step-by-step explanation:

Humans and whales are multicellular (they have many cells) and their cells are eukaryotic (contain a nucleus). They also have a backbone (spinal column), which makes them a vertebrate. Finally, all humans and whales are mammals. Therefore, to get the best results, the testing should be performed on a mouse.

• Performing the experiment on yeast would give good results for singular-celled organisms, like protozoa.
• Performing the experiment on a fruit fly would give good results for multicellular invertebrates, like spiders.
• Performing the experiment on zebrafish would give good results for all fish in general.
