A human arm and a whale fin have similar bone structure but the whale fin is used for swimming and the arm is used for reaching and grabbing. What type of structures are these?

• Homologous structures

• Analogous structures

• Vestigial structures

• Fossil structures

Answer explanation

The correct choice is homologous structures because they share a similar bone structure, indicating a common evolutionary origin despite serving different functions.

The moth wing and the bat wing are example of structures.

(a)  

• Analogous

• Homologous

• Vestigial

• Fossil

Answer explanation

The moth wing and the bat wing are example of analogous structures, which are similar in function but not in structure, indicating convergent evolution.

What is is the study of how and why plants and animals live where they do?

• Evolution

• Adaptive Radiation

• Biogeography

• Biogeology

Answer explanation

Biogeography is the study of how and why plants and animals live where they do, focusing on the geographical distribution of species and ecosystems.

Observe the two fish in the image. The cave fish and minnow are genetically related to each other and are similar in many ways. The cave fish lives very deep in the ocean where there is no light. It has only the remnants of eyes and is blind. Minnows live in shallow waters where the water has light. Their eye sight is important for their survival. Which statement below best describes these two fish?

• The DNA of the cave fish has changed over time to differ from the minnow. Since there is no light where the cave fish lives, it was not necessary to have working eyes. Over time, mutations occurred which proved to improve the survival of the cave fish, which is why they are now blind and have only physical remnants of eyes.

• The DNA has not mutated over time and despite all of the evidence that suggests these two are genetically similar, one has eyes and the other does not so they must not be related.

• Cave fish must have been attacked by predators, which is why they only have the remnants of eyes.

Answer explanation

The DNA of the cave fish has changed over time to differ from the minnow. Since there is no light where the cave fish lives, it was not necessary to have working eyes. Over time, mutations occurred which proved to improve the survival of the cave fish, which is why they are now blind and have only physical remnants of eyes.
