1. What are the three types of homologies that can be seen in organisms? Give an example of each
homology

1. Structural: wings on a bat and arms on a human.

2. Developmental: the halteres of flies are developmentally homologous to the hind wings of moths.

3. Molecular: The same biochemical building blocks, such as amino acids and nucleotides, are found in all organisms, from bacteria to plants and animals. Recall that amino acids are the building blocks of proteins, and nucleotides are the building blocks of DNA and RNA

Explanation:

Definition of homology. 1 : a similarity often attributable to common origin. 2a : likeness in structure between parts of different organisms (such as the wing of a bat and the human arm) due to evolutionary differentiation from a corresponding part in a common ancestor — compare analogy.

   Animal Forelimbs. The forelimbs of a frog, a bird, a rabbit and a lizard look very different because they have evolved differently in response to the evolutionary pressures on each animal. ...

   Bracteate Plants. ...

   Insect Mouthparts. ...

   Snakes and Worms.

The study of similarities is broken up into three main categories: structural, developmental, and molecular homology.

i think the answer is b.
