ASU BIO 182 Exam 1: Questions And
Answers (Verified) how many species live in planet Earth? Correct Ans - unknown- roughly 3 to 5 million why is life so incredibly diverse, yet so strangely similar? Correct Ans - organisms can contain similar features. planes have wings, birds have wings- this feature is useful for different things (different for penguins, pelicans, bats, eagles)
true or false: biodiversity on earth will likely decrease in the near future?
Correct Ans -
true or false: scientists believe in evolution even though they currently lack
evidence for the theory Correct Ans - false
true or false: opposition to irrational numbers was based on evidence that
such numbers cannot exist Correct Ans - false
true or false: opposition to irrational numbers stemmed from a worldview
involving naturalistic evolution Correct Ans - false true or false: the belief that irrational numbers cannot exist reflects religion more than science Correct Ans - true
true or false: modern mathematicians accept irrational numbers because such
numbers provide more accurate solutions to problems than whole numbers do Correct Ans - true the scientific method relies on.... Correct Ans - models, observations, and experiments a model is a formal description of a scientific hypothesis. which provides the most precise description of a hypothesis? Correct Ans - 1 / 2
true or false: an experiment enables one to demonstrate that a correlation
between two variables results from cause and effect Correct Ans - true a well designed experiment... Correct Ans - controls for environmental and genetic factors, involves replications of experimental subjects, and randomizes experimental subject among treatments
true or false: unlike Wallace, Darwin did not believe that natural selection
required variation among individuals Correct Ans - false
true or false: Wallace used induction to develop a model of evolution by
natural selection Correct Ans - true unlike Wallace, Darwin's conceived his theory of evolution without observing species living on islands Correct Ans - false
true or false: both Darwin and Wallace must have assumed that differences
among individuals were passed onto their offspring Correct Ans - true
true or false: similar to Wallace, Darwin conceived a theory of evolution by
natural selection while voyaging around the world Correct Ans - false
true or false: both Wallace and Darwin adopted a worldview described as
either naturalistic evolution or theistic evolutions Correct Ans - true
true or false: a probability of 0.98 means that an event occurs rarely
Correct Ans - false
true or false: when a parent is heterozygous, the probability of passing the
dominant allele to its offspring is 25% Correct Ans - false
true or false: when both parents are heterozygous (Aa), the probability of an
offspring being homozygous recessive (aa) equals 0.25 Correct Ans - true
true or false: a punnett square enables one to determine the frequency of
observed genotypes without using a mathematical formula to calculate the joint probability Correct Ans - true
