Answers (2026/2027) | Graded A+ |
100% Success
chemotherapy - Correct Answer -use multiple drugs to disrupt cell division
meiosis - Correct Answer -cell division that results in 4 daughter cells each with
half the number of chromosomes of the parent cell (production of gametes)
results of mistakes during meiosis - Correct Answer -genetic problems in person /
leads to mutations
3 phases of pregnancy - Correct Answer -1. zygote (when cells come together)
2. embryo (multicellular)
3. fetus (8-9 weeks)
4. baby
first trimester - Correct Answer -month 1-3, major organs & structures begin to
form
,second trimester - Correct Answer -month 4-6, significant bone and muscle
growth
third trimester - Correct Answer -month 7-9, significant development in nervous
system
ways to figure out basic genetics - Correct Answer -punnet square
genetics and probability
patterns of inheritance
process of evolution - Correct Answer -change over many generations in the
relative frequency of alleles that occur in a population
can individuals evolve - Correct Answer -no
what are the smallest biological unit that can evolve - Correct Answer -populations
,theory of evolution - Correct Answer -all species are descendants of a single
common ancestor and all species are a result of millions of years of change
darwin - Correct Answer -he noticed from observations on fossils that certain
organisms looked like each other
what book did darwin publish and when - Correct Answer -origin of species, in
1860
what were the main 2 points of darwin's book - Correct Answer -1. provided
evidence of evolution
2. proposed a mechanism for evolution called natural selection
3 categories of evidence for evolution - Correct Answer -1. fossil record
2. biogeography
3. homologies
4 mechanisms that can cause evolution - Correct Answer -1. natural selection
2. genetic drift
, 3. migration (gene flow)
4. mutation
what are the 3 conditions of natural selection - Correct Answer -1. variation for a
trait
2. heritability
3. differential reproductive success
what determines what traits are favorable in natural selection - Correct Answer -
local environment
"survival of the fittest" - Correct Answer -being fastest, bigger, stronger, etc. does
NOT mean an individual will be favored unless it improves reproductive ability
species - Correct Answer -populations of organisms that interbreed with each
other or could possibility breed, under natural conditions and are reproductively
isolated form other groups
phylogenetic trees - Correct Answer -shows inferred evolutionary relationships
among various biological species
