vestigial structures

b)

analogous structures

c)

homologous structures

d)

embryology

a)
True
b)
False
3.

Abigail, Benjamin, and Jackson are on a virtual field trip to a zoo. They come across the Camelidae family members on their tour. They notice the physical features and the geographical origin of these animals. This observation provides evidence that -

they all live in the same type of environment.

b)

they have slowly evolved to become herbivores.

c)

they have a common ancestor.

d)

they exchanged DNA in the past.

4.

Homologous

b)

Analogous

c)

Embryological

d)

Homologous structure

b)

Analogous structure
