If you're apart of K12 public online school and you're doing this lab report you can find the PDF for the common leaves sheet of the 10 leaves in 3.03 Dichotomous Key Investigation: Dichotomous Key under Materials then you just look at the example and instructions and fill out that way
 
        
             
        
        
        
Answer:
B. Both mussels and barnacles live in the tidal ecosystems.
Explanation:
Mussels are <u>small bivalve molluscs that are adapted to both marine and freshwater ecosystems</u>. Barnacles, on the other hand, <u>are arthropods that are adapted to marine ecosystems. However, both are adapted to shallow and </u><u>tidal</u><u> zones</u>.
Both organisms are small and have the capacity to live in tidal ecosystems where they thrive and play important ecological roles. For instance, barnacles are filtering organisms, which is extremely important for the food chain, and mussels filter out significant amounts of excess nutrients and metals, that is, they make the water more suitable and clean for organisms to live.
As they are both adapted to tidal ecosystems, this would be an example of an adaptation that allows similar species, in this case mussels and barnacles, to live in the same environment. 
 
        
             
        
        
        
The pair of characteristics that one must use to classify a fish is the presence of jaw and skeleton type. Agnatha fishes are also called jawless fishes and they lack bony skeletons. Cartilaginous fishes are composed of cartilage skeletons. Bony fishes have bony skeleton structures.
        
             
        
        
        
Answer:
An animal traveling at 3mm/h east increased his velocity to 5 mm/h east in one hour. What was the animal’s acceleration?
Acceleration= velocity/time
velocity=5mm= 0.005m
time= 1 hour= 60 seconds
A= 0.005/60
Acceleration= 0.000083m/s square

Answer:
The data in the Venn diagram suggest about the realized niches of the cattle and buffalo and their ability to coexist with evidence is discussed below in detail.
Explanation:
2.
From the graph, it is observed that Cattle and Impala have the most overlay in their nutrition.
3.
When Sorensen's index worth is more like 1, there is a contestant among animals for their food manner needs.
From the Venn diagram, we recognize that Cattle and Impala have the most overlay in their nutrition. Also, Sorensen's index worth = 0.82 (closer to 1 concerning other partners.
4.
Sorensen's index for Buffalo and Cattle is 0.48 (cheapest among these 3 partners). So, they are less competitive. So, they can persist and generate easily.
