BSC 2010 (IRSC) Final Exam Questions
and Answers Graded A+
Requirements for natural selection - Correct answer-individual variation, variation
must affect reproductive success, variation must have a genetic basis
Genetic drift - Correct answer-random fluctuations in allele frequencies over time
due to chance
Scientific theory - Correct answer-a well established concept backed up by tests
What happens during crossing-over? - Correct answer-
Differences between passive transport and active transport - Correct answer-
passive: "just happens" due to a concentration gradient active: requires ATP
polymer - Correct answer-long molecules built by linking monomers
monomer - Correct answer-small, similar subunits to polymers
polymers and their monomers - Correct answer-carbohydrates-monosaccharides
nucleic acid-nucleotide
protein-amino acids

, Is a lipid a polymer? - Correct answer-no
M 1 vs M 2 - Correct answer-M1 creates two cells M2 creates four cells, M1 has
synapsis and crossing over and M2 doesn't M1 separates homologous
chromosomes M2 separates sister chromatids
nucleus - Correct answer-repository of DNA
plasma membrane - Correct answer-protects the cell
cell wall - Correct answer-structural support
cytoplasm - Correct answer-suspends organelles
plasmodesmata - Correct answer-transport and communication
mitochondria - Correct answer-generate ATP
central vacuole - Correct answer-storage and maintenance of turgor pressure
golgi apparatus - Correct answer-transports material in and out of the cell
chloroplast - Correct answer-light energy harvested for photosynthesis
nuclear envelope - Correct answer-control passage in and out of nucleus
nucleolus - Correct answer-were ribosome construction begins RNA
rough ER - Correct answer-proteins are secreted
