1. Two species, a cactus and a Venus fly-trap, have a water intake system that's similar in function but not in structure. What type of structure is this?

2. A scientist is trying to determine if two species are closely related or if they just have the same external features. What would you look for to make this determination?

3. A species of beetle in Africa looks really similar to a different species in South America. How would the environment influence species development?

1. homologous structure

2. analogous structure

3. natural selection

4. This is known as an analogous structure.

5. To make this determination, you need to think about if the features are the same in function or also in structure. Features that have a closely related structure and function are likely to be related.

6. To learn more about why your friend is in the hospital, you should research vestigial structures.

7. These two beetles aren't closely related, but they look and behave similarly. This is because they live in the same environmental conditions and likely share a common ancestor that lived in Gondwana (the supercontinent that included the southern continents before they split apart through plate tectonics).

8. Australia has so many genetically distinct organisms because it has been separated from other bodies of land by water for a very long time. This has created an opportunity for long-term independence of other geographic areas.

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.
