BIO 121 Lab 2 Exam(Labs 6-10) UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Enzyme(s) that break down polymers into their monomer forms for Carbohydrates - CORRECT
ANSWER - -Amylase: Group of enzymes that breakdown Carbohydrates
-Released by the Salivary glands in the mouth. Also produced by the pancreas & secreted into
the small intestine
Enzyme(s) that break down polymers into their monomer forms for Proteins - CORRECT
ANSWER - -Protease: Group of enzymes that breakdown Proteins
-Pepsinogen: Released by cells of the stomach lining. Starts breakdown of proteins in the
stomach
Enzyme(s) that break down polymers into their monomer forms for Lipids - CORRECT
ANSWER - -Lipase: Group of enzymes that breakdown Lipids
-Work together w/bile (produced by liver/stored in gallbladder).
-Lipases are produced by pancreas & secreted into small intestine
Know how to do Chi-square and interpret the results (know how to complete table, formulas are
not important) - CORRECT ANSWER -
Know how to use the chart on page 142 in your lab manual to form a conclusion - CORRECT
ANSWER -
Know how to calculate expected numbers from observed - CORRECT ANSWER -
Genotype - CORRECT ANSWER - -Refers to the alleles that are present in an organism
-Ex:Homozygous Dominant: AA (Dominant Characteristic), Heterozygous: Aa (Dominant
Characteristic), Homozygous Recessive: aa (Recessive Characteristic)
, Phenotype - CORRECT ANSWER - -Physical expression of the allelic composition for
the trait under study
-Ex:Having blue eyes or brown eyes
Homozygous - CORRECT ANSWER - An organism that has two identical alleles for a
trait
-Ex: AA or aa
Heterozygous - CORRECT ANSWER - -An organism that has two different alleles for a
trait
-Ex: Aa
Dominant - CORRECT ANSWER - An allele is expressed no matter what the second
allele is
Recessive - CORRECT ANSWER - -An allele that is masked when a dominant allele is
present
-Only expressed when the second allele is the same
Know how to construct a monohybrid/dihybrid punnet square - CORRECT ANSWER -
Predictions of phenotypic ratios of offspring results of a monohybrid or a dihybrid cross, and
given ratios of offspring, predict parental genotypes - CORRECT ANSWER -
Blood typing- phenotypes, interpret results with antisera, transfusions possibilities, heredity -
CORRECT ANSWER -
Blood type A - CORRECT ANSWER - -A proteins present on RBC
-Genotypes: AA, OO
