Introduction to Evolution and Biology Quiz

What is natural selection?

• A theory that all organisms are unchanging

• A method of selecting pets

• Selection for mutations within a species that enhance survivability

• A process where the strongest animals survive

What did Darwin observe in finches on the Galapagos Islands?

• Different sized beaks related to food sources

• Variations in wing size

• Different mating rituals

• Their ability to fly long distances

How do plants produce energy?

• Using energy from the sun, carbon from air, and water

• By moving to sunny areas

• By eating small insects

• Through cellular respiration

What is the difference between DNA and RNA?

• DNA is single-stranded, while RNA is double-stranded

• RNA is only found in animals

• DNA has deoxyribose, RNA has ribose

• DNA uses uracil, while RNA uses thymine

What is the role of ribosomes in a cell?

• The creation of proteins

• Cleaning up waste products

• Packaging and processing proteins

• Creating lipids

What is a key difference between eukaryotic and prokaryotic cells?

• Prokaryotic cells have a nucleus

• Eukaryotic cells are smaller

• Eukaryotic cells have membrane-bound organelles

• Prokaryotic cells perform photosynthesis

What process uses DNA to make mRNA?

• Mitosis

• Translation

• Replication

• Transcription

What must happen for cancer cells to occur?

• Deactivation of proto-oncogenes

• Activation of apoptosis

• Activation of tumor suppressor genes

• DNA polymerase proofreading goes wrong

How do bacteria develop resistance to antibiotics?

• All bacteria are naturally resistant

• By absorbing genes from their environment

• By mutating through random errors in DNA replication

• Through the use of antibiotics

What is epigenetics?

• The study of how behaviors and environment can cause changes that affect the way your genes work

• The replication of DNA

• A change in the DNA sequence

• The process by which organisms evolve
