Question

which of the following help scientist to classify an organism? (choose 2).
embryology
astronomy
fossil records
ecology

Explanation:

• Embryology: The study of embryos can show similarities and differences among organisms, helping in classification. For example, similar embryonic structures in different species may indicate a common ancestor.
• Fossil records: Fossils provide evidence of past life forms. By studying the characteristics of fossils (such as bone structure, size, etc.), scientists can classify extinct organisms and also understand the evolutionary relationships between different groups.

Astronomy is the study of celestial bodies (like stars, planets) and has no direct relation to classifying organisms. Ecology is the study of the interactions between organisms and their environment, which is not directly about classifying the organisms themselves (though it can be related to understanding their habitats, but not the core classification based on biological characteristics).

Answer:

Embryology, Fossil records
