WSU Bio 102 Exam 1 And Exam 2
Questions and Already Passed
Answers 2025-2026 Edition.
evolution - Answer living things change over time
natural selection - Answer explains process of descent with modification (strongest live out
weak creating stronger proceeding generation)
fossils prove 2 things... - Answer 1. life on earth is very old
2. living things have changed over time (some not so much)
"connectedness" in fossils - Answer theory explaining observations that don't make sense in
terms of natural causes.
why whales today have pelvic bone, b/c ancestors had back legs
Louis Pasteur famous for... - Answer -experiment on spontaneous generation of living things
-pasteurization
an _____________ of some phenomenon in nature leads to a ________. A _________ is a
tentative answer to that question. ___________ that come from the hypothesis(if, then...) are
tested with data obtained from additional observations - Answer observation, question
hypothesis, prediction
a theory is a... - Answer multiply-tested and well supported hypothesis
process of science - Answer an observation leads to a hypothesis that leads to a test
scientific theories are ________ and make __________ predictions; describe particular natural
phenomenon - Answer testable & falsifiable
similarities & differences= created by God
, "argument from design" b/c we are so complex we must have been produced by a creator -
Answer William Paley
natural selections unsung hero - Answer Alfred Wallace
Gregor Mendel observed that... - Answer inheritance genes come in pairs (alleles- one from
mom & one from dad) via peas
only _________ alleles, not _________ are expressed in the phenotype - Answer dominant,
recessive
_________= flesh & blood form of person
________= genetic makeup - Answer phenotype vs. genotype
sex linkage explains why - Answer some phenotypes occur more frequently in one sex.
A recessive allele on the x, from mom, can't be masked by dominant allele on Y from dad
example of discrete traits - Answer widow's peak, eye color
controlled by one or few genes
examples of continuous traits - Answer height, IQ\
many genes acting together
P= G x E - Answer Phenotype results from interactions between genes and environment (some
little affected by environment like eye color, while others very affected- IQ)
exception to genes being found on chromosomes in all kinds of cells - Answer mature human
red blood cells
what is a gene - Answer strand of DNA that codes for a protein
proteins are... - Answer fundamental building blocks for phenotypes
