Question

select the correct answers from each drop - down menu
the tentacles of an octopus and the limbs of a lizard perform the same function but have a different evolutionary lineage. therefore, they are
the front legs of a cat and the arms of a human share a bone structure that suggests a common evolutionary lineage. therefore, these skeletal structures are
options in the drop - down menu: analogous, homologous, vestigial

Explanation:

1. For the first statement: Structures that share the same function but have different evolutionary origins are defined as analogous structures. The octopus tentacles and lizard limbs fit this description.
2. For the second statement: Structures that share a similar basic structure due to a common evolutionary lineage (even if their functions differ) are defined as homologous structures. The cat front leg and human arm fit this description.

Answer:

1. The tentacles of an octopus and the limbs of a lizard perform the same function but have a different evolutionary lineage. Therefore, they are analogous
2. The front legs of a cat and the arms of a human share a bone structure that suggests a common evolutionary lineage. Therefore, these skeletal structures are homologous
