what is a homologous structure?

A structure where the function is different and the structure is similar 

100

What is embryological development?

a process by which the fertilized egg turns into an embryo.

100

How much money does a quart of the Horseshoe crab cost?

15,000 dollars a quart.

100

How does fossils relate to evolution?

Fossils relate because it can lead to evolution since you would be able to tell how animals have evolved. And provide important evidence.

100
what is a pathogenic tree?

a tree that shows represents the similarities between two species.

200

what is an analogous structure?

A structure where the function is similar but the function is different  

200

How does embryological development show evidence of evolution?

some homologous structure can be seen only in embryo development.

200

Why is the crabs blood blue?

They have copper in their blood.

200

what is an example that scientist have found that has evolved? 

Horses have shown the largest branching family tree that has evolved.

200

What is the purpose of the tree?

the purpose is to make a hypothesis about there relationships.

300

What is a vestigial structures?

A structure where the function and structure is not useful.

300

what is an example of embryological development?

Humans.

300

Do horseshoe crabs die when they lose their blood

no, they are used to have their blood taken 
300

How do fossils and evolution have a relationship?

Fossils show a progression of evolution. 

300

What does the root of the tree stand for?

the "Branch" corresponds to the common ancestors.

400

What is the structure that has the same structure and different function?

The Homologous  structure.

400

what is another example of embryological development?

 Fish.

Are horseshoe crabs fossils 

Yes, they are living fossils meaning they have lived for over 445 million years.

400

What is one piece of evidence that evolution and fossils relate to each other?

The fossil record of change in earlier species.

400

Are the trees useful?

Yes, they can help find information about the species. 

500

what is a person who studies fossils called?

A Paleontologist.

What is a fossil?

A trace or print of remains of an old living organism.

500

Why is horseshoe crabs blood so expensive?

it contains a special blood clotting agent.

500
True or False are humans still evolving?

True, they are constantly evolving.

500

Are humans and trees related?

Yes, they all have a common ancestor.
