Biology Eca Review

Front 1

3 phases of logistic growth

Back 1

phase 1. population grows rapidly, phase 2. growth slows, 3. growth stops; population size stabilizes at carrying capacity.

Front 2

analogous

Back 2

body parts that share common function, but not structure, and that do not share a common ancestor

Front 3

anaphase 2 (meosis 2)

Back 3

the paired chromatids separate

Front 4

anaphase 1 (meosis 1)

Back 4

spindle fibers pull each homologous chromosome pair toward opposite ends of the cell

Front 5

anaphase (mitosis)

Back 5

the chromosomes separate and move along the spindle fibers to opposite ends of the cell

Front 6

carrying capacity

Back 6

the maximum number of individuals of a particular species that a particular environment can support

Front 7

cytokindsis (meosis 1)

Back 7

two new cells are formed called daughter cells

Front 8

cytokinesis (mitosis)

Back 8

the cell splits into two

Front 9

deciduous forest

Back 9

deciduous and coniferous trees

Front 10

density dependent limiting factors

Back 10

operate strongly only when population density reaches a certain level

Front 11

density independent limiting factors

Back 11

factors that affect all populations in similar ways regardless of population size and density

Front 12

desert

Back 12

low precipitation

Front 13

diploid

Back 13

two complete sets of inherited chromosomes and two complete sets of genes

Front 14

8 levels of taxonomic organization

Back 14

domain, kingdom, phylum, class, order, family, genus, species

Front 15

exponential growth

Back 15

the larger population gets, the faster it grows

Front 16

g1 phase (mitosis)

Back 16

cells increase in size and synthesize new proteins

Front 17

g2 phase (mitosis)

Back 17

many of organelles and molecules required for cell division are produced

Front 18

grasslands

Back 18

grassland plants are resistant to fire and spread seeds by wind

Front 19

haploid

Back 19

contain only one set of chromosomes and only a single set of genes

Front 20

homologous

Back 20

structures that are shared by related species and that have been inherited from a common ancestor

Front 21

homologous

Back 21

each of the four chromosomes from the male parent has a corresponding chromosome from the female parent

Front 22

Interphase (mitosis)

Back 22

an "in-between" period of growth divided into 3 parts: g1, S, and g2

Front 23

in what situation does natural selection occur?

Back 23

any situation in which more individuals are born than can survive(the struggle for exstensice) there Is natural heritable variation (varation and adaptation) and there is variable fitness among individuals (survival of the fittest)
