Answer:
They are nonlobed, simple leaves and are attached oppositely on the branch.
Explanation:
A dichotomous key is a tool you use in biology to know the identity of things in nature such as trees,flowers, fish or even rocks. This key has choices that follow each other in a progressive manner, where one choice led to the other until you identify the item.In this case, to identify Dogwood, you follow the below steps;
1b. Broad leaf = Step 2
2b. Simple leaf = Step 7
7a. Leaf bases attached opposite each other on branch = Step 8
8b. Leaves not lobed = Step 9
9b. Leaves not heart shaped = Dogwood
The key is (1b,2b,7a,8b,9b)
 
        
             
        
        
        
The dependent variable is the data we collect during the experiment. This data is collected as a result of changing the independent variable.

<span>There are four different examples of food chains in the movie "Finding Nemo".

5) Crabs scavenging for food from/along the pipes on the ocean floor 
6) Baracuda (scary fish) eats fish eggs at beginning of movie and Nemo's mom. 
7) The french shrimp cleans the tank by eating the algae and other build up. </span>
