Question 1

Morphology

Answer 1

-structure and form of organisms

Question 2

phylogeny

Answer 2

-evolutionary history of a species

Question 3

morphological species concept

Answer 3

-compares measurements & description of similar organisms

-after comparison scientist decide wether similar organisms represent different species

Question 4

biological species concept

Answer 4

*mating concept

if two individual organisms can mage under natural circumstances and produce off spring that can successfully live and reproduce, then the two species are the same

Question 5

phylogenetic species concept

Answer 5

a organisms is defined as a cluster of cells distinct from other clusters and shows a pattern of relationships amount organisms

Question 6

Answer 6

1. Genus (capitalized)
2. species name
   *italicized
   *underlined when hand written

Question 11

Physiology + examples

Answer 11

branch of biology dealing with physical and chemical functions of organisms

*including internal process

ex: comparing proteins, degree of genetic similarity or difference

Question 12

DNA evidence of relationships- what are genes

Answer 12

genes are sections of DNA made of long chains of molecules called nucleotides

Question 13

what are phylogenetic trees used for

Answer 13

used to represent a hypothesis about evolutionary relationships among organisms

Question 14

what is a clade

Answer 14

a section of a phylogenetic tree that allows you to see descendants of common ancestors

Question 15

what are the 3 domains

Answer 15

bacteria, archea, and eukarya

Question 16

what is species diversity

Answer 16

the variety and abundance of a species in a given area

Question 17

genetic diversity

Answer 17

the variety of heritable characteristics (genes) in a population of interbreeding individuals

Question 18

what do genes control

Answer 18

-expression and inheritance of traits
*variation in individuals is a result of the differences in their genes

Question 19

what is the gene pool

Answer 19

*genetic diversity within a population
sum of all the versions of all the genes of all the genes in a population

Question 20

what do genetic diversity support

Answer 20

resistance to disease- if genes are all the same, if 1 can’t survive none could

conservation biology- use knowledge to help struggling populations

Question 21

biotic

Answer 21

living

Question 22

abiotic

Answer 22

non-living

Question 23

ecosystem services

Answer 23

benefits experienced by organisms provided by sustainable ecosystem

Question 24

ecosystem function & species diversity

Answer 24

ecosystems with greater species diversity are more likely to provide important services reliably

Question 25

ecosystem services and human actions example

Answer 25

sometimes humans make chance to an ecosystem to enhance the services of the ecosystem

ex: stocking a lake with fish
