According to the cladogram, Osteichthyes belong in group A.
Osteichthyes are a class of fish that have real bones and jaws as derived traits. These derived qualities can therefore be traced backwards from group A, with each line indicating a connection or relationship.
What is Cladogram?
- In cladistics, a cladogram is a diagram that is used to depict relationships between species.
- Cladograms reconstruct the taxa's evolutionary history (phylogeny) by showing these links. Phylogenies and trees are other names for cladograms.
- A cladogram's root, clades, and nodes are its most important components. The root is the first ancestor shared by all groups that branched off from it. The branches that represent related groups and their shared ancestors are known as clades. The points known as nodes represent the fictitious ancestors.

The city water is maintained by the city while with the well water, you maintain it yourself. Even though it can be pricey, most people live in the city anyway, so there is easier access to it.
Explanation:
Freshwater means low salt content. The zones namely Standing which is compose of ponds and lakes and has littoral zone which algae,floating aquatic plants and clams can be found. Next is limnetic zone and has plankton. Next is Flowing includes streams and rivers and in there resides catfish and carp. For sea water it has Marine which has aphotic zone where anemones,arrow worm and angler fish resides.Another, coastal zone compose of coral reefs and mangrove and lastly the intertidal zone with small critters.
A prediction is a guess what might happen based on observation.
Here are some steps to think about to make a dependable prediction:
Collect data using your senses, remember you use your senses to make observations.
Search for patterns of behavior and or characteristics.
Develop statements about you think future observations will be.
Test the prediction and observe what happens.
A hypothesis is a possible explanation for a observation or problem that can further be tested by experimentation. Hypothesis' are also known as educated guesses.
Here are the steps to form a hypothesis:
When developing a hypothesis think about any observations or previous knowledge you know about the variables.
Express what you think will be the effect of changing one of the variables (Independent variable) on the other variable you expect to change (Dependent variable).
Develop your hypothesis using a statement.
A example of a hypothesis statement would be, As the (independent variable) ( describe how you would change it) , then the (dependent variable ) will (describe the effect)
