GEN BIO WEEK 6 AND 7

animal or plant tissues preserved in sedimentary rocks and is formed with more organic material

• Imprints

• Compressions

• Genetic Information

• Fossil Records

traces of organisms that lived in the past and were preserved by natural process or catastrophic events

• Comparative Anatomy

• Embryonic Development

• Genetic Information

• Fossil Records

Method is used to determining the age of rocks using the decay of radioactive isotopes of C-14 which is present in rocks when the organism died.

• Carbon Decay

• Compressions

• Radiometric Dating

• Carbon 14

is the change in inherited

traits over successive generations

in populations of organisms

this change allowed organisms to adapt and survive in their environment

• Evolution

• Anatomy

• Homologous

• Fossils records

The body parts of organisms that may perform the same function but are of different origins

• Homologous structures

• Analogous structures

• comparative anatomy

• Radiometric dating

the study of the similarities and differences in the structures of different species

• Comparative Anatomy

• Fossil Records

• Embryonic development

• Radiometric dating

According to this data, the unknown bacterial species is most closely related to: 

• Species I

• Species II

• Species III

• Species IV

What is the study of organisms at the early stages of development?

• vestigial structures

• homologous structures

• embryology

• fossil records

What is the study of organisms at the early stages of development?

• DNA studies

• Extinction

• embryology

• fossil records

Two organisms that are closely related would have

• very similar DNA sequence

• no proteins in common

• exactly the same DNA sequences

• completely different DNA sequence
