Question

1 multiple choice 20 points which statement is correct? when scientists are comparing anatomical structures... (dok 1) analogous structures are identical in all species and give no clues about common ancestry. homologous structures are similar in different species because they were inherited from a common ancestor. homologous structures are similar because they perform the same function, not because of common ancestry. analogous structures are inherited from a common ancestor that looked nothing like the current organism. 2 multiple choice 20 points how does comparative morphology support the theory of evolution? (dok 2) comparative morphology only studies the color of organisms and what kind of skin they have. comparative morphology focuses on the diet of organisms and compares it to the diet of the same organism in a different ecosystem. comparative morphology provides evidence for evolution by showing similarities in bone structures among different species. comparative morphology is used to classify organisms based on habitat.

Explanation:

• Question 1: Homologous structures are anatomical features in different species that are similar because they were inherited from a common ancestor. Analogous structures, on the other hand, have similar functions but different evolutionary origins.
• Question 2: Comparative morphology supports the theory of evolution by showing similarities in bone structures (homologous structures) among different species. This indicates a common evolutionary ancestry.

Answer:

1. Homologous structures are similar in different species because they were inherited from a common ancestor.
2. Comparative morphology provides evidence for evolution by showing similarities in bone structures among different species.
