Biology Final Exam Key Concepts with
Complete Solutions
What are two differences between mitosis and meiosis? - ANSWER-In meiosis,
during Metaphase I, chromosomes align with their homologous pairs
In Mitosis, 2 daughter cells are yielded, in meiosis, 4 daughter cells are yielded
What is transcription? - ANSWER-DNA to RNA
What is translation? - ANSWER-RNA to protein
What is endotherm? - ANSWER-forms digestive and respiratory organs
What is ectoderm? - ANSWER-forms skin, nervous system and sense organs
What is eutrophication? - ANSWER-is excessive richness of nutrients in a lake or
other body of water
What is a nerve net? - ANSWER-is the simplest form of a nervous system found in
multicellular organisms
What is meant by "crossing over" during the process of meiosis? - ANSWER-it is
when a piece of one chromosome, in the homogelous pair, breaks off and attaches
to the other chromosome
What is cytokenesis? - ANSWER-the division of the cell into two daughter cells
What are genetically modified (GM) foods? - ANSWER-foods that are produced from
organisms that have had changes introduced into their DNA
What kind of animals have an endoskeleton? - ANSWER-vertebrates
What is a chloroplast? - ANSWER-sight of photosynthesis, only found in plants,
where carbon dioxide and water are converted into sugars
What is the equation for photosynthesis and where does it occur? - ANSWER-It
occurs in the Chloroplast
Carbon dioxide + water + sunlight = glucose + oxygen
Where does cellular respiration occur? - ANSWER-It occurs in the mitochondria
(stroma)
