Q

What do we mean when we use genetic resources as provisioning services.

A

Improvement of products e.g. bross-bred wild crop genes improving crop resistance to drought, disease, pests.

15
Q

Data vs. Facts

A

Data: recorded observations/items of information

Facts: Data that has been repeatedly confirmed by observation or experimentation

16
Q

The basis of inductive reasoning is…

A

generalizations based on many specific observations

specific –> general

17
Q

What are the colloquial and scientific definitions of hypothesis?

A

Colloquial: guess/idea about something uncertain

Scientific: ideas about questions that lead to testable nd falsifiable predictions

18
Q

The basis of deductive reasoning is…

A

the use of general premises to make specific predictions (logic)

general –> specific

19
Q

Taxonomy

A

the scientific discipline concerned with naming and classifying organisms

20
Q

Nomenclature

A

the system of rules for naming things

21
Q

Why is nomenclature important?

AKA what are some problems with common names?

A
  1. different names can be used for the same species
  2. same names can be used for different species
  3. common names might imply relationships that don’t exist
22
Q

What are the two key fetures of the Linnaean System of Nomenclature?

A
  1. Hierarchical classification of species into groups based on structural, functional, and other similatirites
  2. Binomial nomenclature
23
Q

Two parts of binomial names:

A

Genus specificepithet

24
Q

Order of the Linnaean Hierarchy (the taxonomic ranks

A

Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species

25
Q

define

Taxon

A

A taxonomic rank at a level of a hierarchical classification

26
Q

Limitations of hierarchical classifications

A
  1. Characteristics that are used to classify groups of species must be tailored to the species in question
  2. no evolutionary information can be inferred
27
Q

What are the three Domains?

A

bacteria, archaea, eukarya

28
Q

Three kingdoms of Eukaryotes

A

plantae, fungi, animalia
