Answers |Latest Version |Already Graded A+
prokaryote cell ✔Correct Answer-single-celled organism without a nucleus
eukaryote cell ✔Correct Answer-A cell that contains genetic information or DNA in the nucleus like
most organisms
plant cells = photosynthesis ✔Correct Answer-some protists/ bacteria
Deoxyribonucleic acid (DNA) ✔Correct Answer-A double-stranded, helical nucleic acid molecule
capable of replicating and determining the inherited structure of a cell's proteins
asexual reproduction ✔Correct Answer-simple cell division, genetically identical offspring
sexual reproduction ✔Correct Answer-requires two individuals
mutations ✔Correct Answer-a change in DNA
phenotypes ✔Correct Answer-how an organism looks and functions; product of DNA (genotype)
and environment
growth of population (growth rate) ✔Correct Answer-(births + immigration) - (deaths + emigration)
habitat ✔Correct Answer-the environment an organism depends on
niche ✔Correct Answer-role of the organism in the habitat
range of tolerance ✔Correct Answer-determines habitat and niche; temperature, space, and
chemicals/ nutrients
natural selection ✔Correct Answer-most fit leave more offspring
least fit have fewer offspring
directional selection ✔Correct Answer-removes one particular extreme phenotype from the
population
stabilizing selection ✔Correct Answer-removes extreme phenotypes from the population
disruptive selection ✔Correct Answer-removes medium-sized phenotypes from the population
evolution ✔Correct Answer-a genetic change
species ✔Correct Answer-organisms that can breed and produce fertile offspring
reproductive isolation ✔Correct Answer-behavioral; courtship rituals
structural; genital incompatibility
taxonomy ✔Correct Answer-classification of organisms (based on evolutionary ancestry)
, UN population division ✔Correct Answer-collect demographic data for 195 countries
human behavior ✔Correct Answer-cultural values and social policy
UN Sustainable Development Goals ✔Correct Answer-8/17 SDG's focus on human well-being and
have potential to influence human population
demographic transition model ✔Correct Answer-A sequence of demographic changes in which a
country moves from high birth and death rates to low birth and death rates through time.
pretransition (stage 1) ✔Correct Answer-high death rates & birth rates
mortality transition (stage 2) ✔Correct Answer-low death rates and birth rates stay high; rapid
population growth
fertility transition (stage 3) ✔Correct Answer-low death rate and low birth rate; population growth
is slow
stability transition (stage 4) ✔Correct Answer-low birth rate and death rate; birth and death rates
are equal; zero population growth
birth rate ✔Correct Answer-the number of live births per thousand of population per year
death rate ✔Correct Answer-Total number of deaths each year for every 1,000 people in a place
infant mortality rate ✔Correct Answer-percentage of children that die before the age of 1
age structure pyramid ✔Correct Answer-number of males and females of each age in a population
immigration ✔Correct Answer-people moving into a country
pull factors of immigration ✔Correct Answer-freedom, education, employment
emigration ✔Correct Answer-people leaving a country
pull factors of emigration ✔Correct Answer-wars, famine, oppression, and persecution
net migration rate ✔Correct Answer-difference b/w immigration and emigration
china's approach to reduce population ✔Correct Answer-one child policy
india's approach to reduce population ✔Correct Answer-education and voluntary, postponement
of marriage and children
sustainability ✔Correct Answer-The ability to keep in existence or maintain
carrying capacity ✔Correct Answer-size of population the environment can support
ecological footprint ✔Correct Answer-A measure of how much an individual consumes, expressed
in area of land
