Biol 1108 KSU Exam Questions with
Correct Answers 2026
Science - CORRECT ANSWER -
a way of knowing that deals with what is directly observable and leaves the rest to other
ways of thinking
Inquiry - CORRECT ANSWER -a search for information
Discovery science - CORRECT ANSWER -describes natural structures to formulate hypothesis
Hypothesis based structure - CORRECT ANSWER -
specific questions, makes predictions that can be tested, falsifiable
Scientific theory - CORRECT ANSWER -
broad in scope, generates new hypotheses, supported by experimental evidence
Evolution - CORRECT ANSWER -
change over time in the genetic composition of a population descent with modification
Adaptation - CORRECT ANSWER -
a genetically inherited characteristic that enhances an organisms ability to survive and repr
oduce
Biological fitness - CORRECT ANSWER -
the contribution an organism makes to the gene pool of the next generation, relative to th
e contribution of others
, Artificial selection - CORRECT ANSWER -
the intentional reproduction of individuals in a population that have desirable traits
ex. Brassica oleracea, a wild mustard
Darwin's 4 Observations - CORRECT ANSWER -
1. Members of a population often vary greatly in their traits
2. Many of these traits are inherited from parents to offspring
3. Species are capable of producing more offspring than their environment can support
4. Lack of these resources will prevent many of these offspring from surviving
Darwin's 2 Inferences - CORRECT ANSWER -
1. Individuals whose inherited traits give them a higher probability of surviving and reprodu
cing in a given environment tend to leave more offspring than other individuals
2. This unequal ability of individuals to survive and reproduce will lead to the accumulation
of favorable traits in the population over generations
Population - CORRECT ANSWER -
a localized group of individuals that are capable of interbreeding and producing fertile offsp
ring
Alleles - CORRECT ANSWER -different copies of the same gene
Gene pool - CORRECT ANSWER -
the total aggregate of all copies of all alleles in a population at the same time
Mutations - CORRECT ANSWER -
changes in DNA sequence, may be neutral, or may change the phenotype (for better or wo
rse), rare on the whole, but generally occur in low levels in every individual in every gener
ation (1 in every 30 mill base pairs on human Y chromosome per generation)
