Unit 4 - Adapt or Go Extinct Final Exam (23-24)

What is the importance of the geologic time scale?

• It shows how old the Earth is
• It shows how important the Earth is
• It categorizes the significant events on Earth
• It shows when mass extinctions happened

With the help of these 3 pieces of evidence, scientists are able to show evolution happens. What are these 3 pieces of evidence?

• Fossils, embryonic development, anatomical structures
• Fossils, anatomical structures, biodiversity
• Fossils, Galapagos Islands, Darwin
• Fossils, biodiversity, natural selection

Predict why natural selection is also referred to as "survival of the fittest".

• Nature selects who survives
• Nature picks only the strongest to survive
• You need to be healthy in order to survive
• Nature selects the best adapted to survive

What is the relationship between natural selection and phenotype?

• There is no relationship between natural selection and phenotype
• Natural selection chooses based on the phenotype
• Natural selection and phenotype are the same thing
• Natural selection shows us the phenotype

Which one is NOT a principle of natural selection?

• Overproduction
• Genetic variation
• Competition
• Evolution

The phenotype is ________ whereas the genotype is ________.

• Showing traits, traits within DNA
• Traits within DNA, showing traits
• Important, is not important
• Homozygous, heterozygous

If the trait for green eyes is dominant (G) and blue is recessive (g). Which genotype would you expect to have blue eyes?

• Homozygous recessive
• Homozygous dominant
• Heterozygous
• GG

If a chromosome had the genes A-B-C-D-E-F-G, predict what the chromosome would look like with an inversion mutation from "D-G".

• A-B-C-D-E-G-F
• A-B-C-G-F-E-D
• A-B-C-G-E-F-D
• G-F-E-D-C-B-A

Which one is a chromosome mutation?

• Translocation
• Missense
• Nonsense
• Frameshift Deletion

Infer as to why chromosomal mutations are more dangerous than gene mutations.

• Chromosomes are bigger
• Chromosomes code for phenotypes but genes code for genotypes
• Chromosome mutations affect more genes
• Chromosomes code for DNA but genes code for proteins
