Answers 100% Verified
biotic potential Correct answer-most populations are capable of producing more
offspring then can be supported by the environment
heritable Correct answer-pass it onto the next generation
Evolution of acquired characters Correct answer-overtime, an organism could acquire
enough changes that one species could diverge into two
this branching extended back in time, ancestral species to ancestral species and so on
Five agents of evolution: Correct answer-natural selection
sexual selection
gene flow
genetic drift
mutation
gene flow Correct answer-the movement of alleles from one population to another by
migration
gene flow introduces Correct answer-'novel' alleles to a population from some other
population

genetic drift Correct answer-chance alteration of allele frequencies in a population
founder effect Correct answer-colonization of new habitat y a few individuals that give
rise to a new population. note: founding individuals do not represent the total genetic variation
in original population
genetic drift - population bottleneck Correct answer-survival is random, surviving
individuals do not represent the genetic diversity of the original population, new population
arises
sexual selection Correct answer-differential reproductive success based on differences in
the success of obtaining mates
-female mate choice
-male dominant systems
-both are non random mating
allopatric speciation Correct answer-occurs when the geographical range of a species is
split into discontinuous parts by formation of barriers to gene flow
--populatioins become isolated in different arears
Evolutionary Tree--Ancestral characters Correct answer-characters existed in the common
ancester

Evolutionary Tree--Derived characters Correct answer-characters unique to a certain
group
tissue Correct answer-a group of cells of a similar type that work together for a common
purpose
four types of tissue Correct answer-epithelial
connective
muscle
nervous
Epithelial Correct answer-covers body surfaces, lines cavities and organs
Three basic shapes of Epithelial Tissue Correct answer-squamous
cuboidal
columnar & in simple (single layer) or stratified forms
connective tissue Correct answer-most abundant tissue
binds-tendons and ligaments
supports-cartilage, bones

Answers 100% Verified
transports-blood
stores energy-adipose tissue (fat)
Connective tissue defined Correct answer-cells embedded in extracellular matrix
composed of protein fibers and ground substances
3 proper connective tissues Correct answer-areolar
adipose
dense
areolar Correct answer-widely distributed; under skin, around organs and muscles ----for
structure and cushioning
adipose Correct answer-(fat) under skin, around organs;
function; energy storage, insulation, cushioning
dense Correct answer-tendons and ligaments
---attach bone to muscle or bone to bone
3 special connective tissues Correct answer-cartilage
bone
