• If they have similar characteristics they are grouped together.

• Each group is organized into more specific groups.

• All of these answers are true.

What characteristics describe parts of an organism that you canNOT see?

• external structure

• internal structure

• genetic similarities

• embryology similarities

What characteristics show that similar organisms have similar DNA and similar characteristics?

• external structure

• internal structure

• genetic similarities

• embryology similarities

What characteristics show that similar organisms develop similarly (the embryos look nearly the same)?

• external structure

• internal structure

• genetic similarities

• embryology similarities

What characteristics describe parts of the organism that you can see?

• external structure

• internal structure

• embryology similarities

I can see that dogs, cats, and elephants all have 4 legs. This is an example of:

• external structure

• internal structure

• genetic similarities

• embryology similarities

Catfish and goldfish both have organs that allow them to breath underwater . This is an example of:

• external structure

• internal structure

• genetic similarities

• embryology similarities

Chickens and eagles lay eggs; this is where their babies grow and develop before they hatch. This is an example of:

• external structure

• internal structure

• genetic similarities

• embryology similarities

The colors of my hair and my eyes are the same as my mom's because I have her DNA. This is an example of:
