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?

Answer from: khayes7400

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 scientific method is a series of steps followed by scientific investigators to answer specific questions about the natural world. it involves making observations, formulating a hypothesis, and conducting scientific experiments.the steps of the scientific method are •observation-the first step of the scientific method involves making an observation about something that interests you•question-once you've made your observation, you must formulate a question about what you have observed. •hypothesis-once you've made your observation, you must formulate a question about what you have observed. •experiment-once you've developed a hypothesis, you must design and conduct an experiment that will test it.•results-the results are where you report what happened in the experiment. •conclusion-the final step of the scientific method is developing a conclusion.i hope that this you : )

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
