What's the function of a dichotomous key?
My Answer: Dichotomous Key use by scientists are arranged in steps with two descriptive statements at each step.
Is my answer to this question is correct???
BTW: I got this answer from my textbook in that section that my science teacher assign the class to do for homework tonight and answer 3 questions.
Your answer is not correct. The question asks what is the purpose of the dichotomous key.
Use the dichotomous key to answer the question.
Dichotomous Key
1a. Needle leaves: go to step 2
1b. Non-needles leaves: go to step 3
2a. Needles are grouped in clusters: pine tree
2b. Needles are individually arranged: spruce tree
3a. Simple (individual) leaves: go to step 4
3b. Compound leaves (leaflets): go to step 5
4a. Leaf edge is smooth and lobed: oak tree
4b. Left edge is rough and tooth-like: elm tree
5a. Leaflets are attached at one point: chestnut tree
5b. Leaflets are attached at many points: walnut tree
Examine the leaf.
Non-needle green leaf with compound leaves attached at the center.
What kind of tree is the leaf from?

ok...
I'll go back to my textbook and then I'll post my answr again to see if I'm right.
The purpose of a dichotomous key is to take an organism, say a confier tree, and make note of its features and then look at a dichotomous key to identify what species it is based on its features.
Is my answer to this question is correct???
OK!
Thank You Ms. Sue for checking my answers for all of my 3 science questions!!!! :)

Examine the two spiders.
Two spiders, side by side. One spider is black with eight segmented legs and a long, thin body. The other spider is brown with eight segmented legs and a short, wide body.
Which characteristic would best identify the spiders as belonging to different species?
(1 point)
The best characteristic that would identify the spiders as belonging to different species is the body shape. Specifically, the difference in body shape is described, with one spider having a "long, thin body" and the other spider having a "short, wide body."
The leaf is from a Chestnut Tree, as described in step 5a of the dichotomous key.
OR
The purpose of the dichotomous key to identify what species it is based on its features.
Which one is better the first one or the one I just wrote.
