Question 3
Now, click the "Play" button under Red, green, and gecko. Drag both the gecko and tree to the black box. Then drag the blue ball underneath where the branches split off and click "Next." Now use the magnifying glass to explore the three species. Select the box, if the species has the trait in the below table.(1 point)
Cells with Nuclei Photosynthetic autotroph Heterotrophic
Flu agaric mushroom
Palm Tree
Gecko
Question 4
Now, drag the colored trait balls to the tree. You will place the trait below the species that have that trait. Once you have completed the tree, you can tell which species are most closely related by, how many branches they have in common. Which species is the mushroom more closely related to?(1 point)

Put responses in the correct input to answer the question. Select a response, navigate to the desired input and insert the response. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse.
When we scientists say two species are more closely related, another way of saying it is they share a Response area common ancestor.

Question 10
Finish this tree. If you are having a hard time, pair the species by the number of petals first. If you are still have difficulty with this (which is totally ok, this is not easy!) I did Banana, Onion, Lemon, Radish, and Seaweed in that order. You do not have to have the same order has me. According to this tree, what is a banana most closely related to?(1 point)

Question 11
Explain why phylogenetic trees are important in understanding evolutionary relationships among species. (3 points)
Responses
Phylogenetic trees are important because they visually depict the evolutionary relationships among species. By showing how species are related to each other through a common ancestor, phylogenetic trees help scientists understand the history of life on Earth and how different species have evolved over time. These trees provide valuable information about the diversity of life and help scientists make predictions about future evolutionary patterns. Ultimately, phylogenetic trees are essential tools for studying and interpreting the complex relationships between different organisms.
