Q

taxonomy

A

The branch of biology concerned with naming and classifying

Q

binomial nomenclature

A

– This system was instituted by Carolus Linneaus
– The first name designates the genus, or group of closely related
organisms, that the species is a member of.
– The second name is a specific epithet, unique for each species within a genus

16
Q

consumer

A

obtains energy and nutrients by eating other organisms

17
Q

producer

A

Plants (and certain other organisms) are able to capture solar energy and perform photosynthesis.

18
Q

adaptation

A

modifications that make organisms suited to their way of life.

19
Q

information theme

A

involves expression and transmission of genetic information

20
Q

energy and matter theme

A

producers and consumers

energy flow and energy cycling

21
Q

interaction theme

A

feedback regulation - output or product of a process regulates that very process

22
Q

negative feedback

A

most common.

the response reduces the initial stimulus

23
Q

specific epithet

A

unique for each species within a genus

24
Q

taxon

A

the named taxonomic unit at any level of the hierarchy.

For example – Panthera is a taxon at the genus level, Mammalia is a taxon at the class level, etc.

25
Q

what is a scientific fact?

A

A scientific fact is an objective and verifiable observation.

Any scientific hypothesis or claim must be falsifiable

26
Q

principles of science

A
  • Every assertion regarding the natural world is subject to challenge and revision based on evidence
  • Any scientific hypothesis or claim must be falsifiable
  • Scientific inquiry concerns itself only with natural explanations for natural phenomena
  • Parsimony (Occam’s razor): the simplest explanation is usually the correct one
27
Q

Which level of organization is the fundamental unit of life?

A

a cell

28
Q

How does our current system of taxonomic organization differ from the system proposed by Linnaeus.

A

The most important difference between classification during the time of Linnaeus and current classification is that organisms are now grouped according to their
evolutionary relationships

29
Q

One goal of scientists is to assign every organism a universally accepted name according to the system know as:

A

binomial nomenclature

30
Q

Systematics is:

A

a science of name and grouping organisms

31
Q

Modern systematic try to group organisms based on:

A

evolutionary relationships

32
Q

The goal of systematic is to organize living things into groups, called _____, that have biological meaning.

A

taxons
