Q

Phylogenetic Tree

A

a diagram that depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor.

17
Q

Homologous Structure

A

similar physical features in organisms that share a common ancestor, but the features serve completely different functions.

18
Q

Prokaryotic Cell

A

no membrane bound organelles

19
Q

Eukaryotic Cell

A

membrane bound organelles

20
Q

Dichotomous Key

A

ask yes or no questions to classify a newly discovered organism compared to existing organisms

21
Q

Autotroph

A

produces its own food
can either be photosynthetic or chemosynthetic

22
Q

Heterotroph

A

eats other organisms to get energy

23
Q

natural selection

A

the process through which populations of living organisms adapt and change.

24
Q

Artificial Selection

A

the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations

25
Q

How to classify species

A

dichotomous keys
