GRADED A+ LATEST 100%
GUARANTEED PASS
Name 5 fundamental characteristics that all living things have - CORRECT ANSWER-cells
replication
evolution
information (hereditary)
energy
describe 2 components of the cell theory - CORRECT ANSWER-- all cells are made of cells
- cells come from preexisting cells
explain theory of natural selection - CORRECT ANSWER-- process where populations of
organisms adapt and change
- variation in traits in a population: those with certain traits will survive and have higher fitness
(more offspring)... as these traits are pass on, the allele freq increases where eventually a whole
pop could have the trait
, 2 conditions that are necessary and sufficient for natural selection to bring about evolutionary
change - CORRECT ANSWER-- individuals must vary i traits that heritable
- in a particular environment, certain versions of these heritable traits help individuals
reproduce more than other versions
how to read a phylogenetic tree (role of similarities and differences) - CORRECT ANSWER--
similarities and differences are what guide the production of a tree
what do biologists do? (how they approach problems / why they do experiments) - CORRECT
ANSWER-- state precise hypothesis and list predictions it makes
- null hypothesis
- design observational/experimental study capable of testing predictions
- results and compare to hypothesis
what makes an experiment well designed? - CORRECT ANSWER-- control group
- experimental conditions were controlled
- test was repeated to reduce effects of distortion due to sample size
test whether evolution or nonrandom mating is occurring at a particular gene (hardy-weinberg
principle) - CORRECT ANSWER-p^2 + 2pq + q^2 = 1
A1 = p
A2 = q
Frequencies:
A1A1 = p^2
A2A2 = q^2
A1A2 = 2pq
