Question

Organisms that belong to the same ___ are most closely related.

Answer 1

Organisms from the same species are most closely related due to significant genetic similarities and shared characteristics that arise from their DNA. Homologous structures and DNA sequences indicate close evolutionary relationships. The taxonomic classification system reflects the degree of relatedness amongst organisms.

Step-by-step explanation:

Organisms that belong to the same species are most closely related. Members of the same species have significant genetic similarities and share both external and internal characteristics that are developed from their DNA. The closer relationship two organisms share, the more DNA they will have in common, resulting in shared characteristics and behaviors that are advantageous for successful reproduction.

Homologous structures, such as similar physical features and genomes, serve as evidence of a common ancestor and evolutionary relationship between organisms. This implies that organisms with more similar DNA sequences are more closely related evolutionarily. In the taxonomic classification system, the closer the classification (such as species or genus), the more closely related the organisms are expected to be.

Answer 2

Family

Step-by-step explanation:

-------------------1--------2-------------3

Kingdom Animal --Animal ---Animal

Phylum Chordate- Chordate - Chordate

Class Mammal - Mammal- Mammal

Order Primate Carnivore Carnivore

Family Hominidae Felidae Felidae

Genus Homo Panthera Felis

Species Sapiens Leo Domesticus

Organisms 2 and 3 are most closely related because they have the same family name. Organism 2 is a lion, organism 3 is a common housecat, and organism 1 is a human.
