Answers Assessment Test (2024)
Graded A+
Coevolution Event - Answer - The process by which two or more species evolve in
tandem by exerting selection pressures on each other
Speciation Event - Answer - A lineage-splitting event that produces two or more
separate species.
Phylogenetic Event - Answer - The evolutionary development and history of a species
or higher taxonomic grouping of organisms. Also called phylogenesis. The evolutionary
development of an organ or other part of an organism
Homology Event - Answer - Shared trait among species
Mutation - Answer - A Mutation occurs when a DNA gene is damaged or changed in
such a way as to alter the genetic message carried by that gene.
Gene Flow - Answer - is the transfer of alleles or genes from one population to another.
Migration into or out of a population may be responsible for a marked change in allele
frequencies (the proportion of members carrying a particular variant of a gene).
Genetic Drift - Answer - is the change in the frequency of an existing gene variant
(allele) in a population due to RANDOM sampling of organisms. Ex. Earthquake or
disaster
, Artificial Selection - Answer - The breeding of plants and animals to produce desirable
traits
Krebs Cycle/Citric Acid Cycle - Answer - release stored energy through the oxidation of
acetyl-CoA derived from carbohydrates, fats, and proteins into carbon dioxide and
chemical energy
Calvin Cycle - Answer - is the set of chemical reactions that take place in chloroplasts
during photosynthesis.
Electron Transport Chain - Answer - A group of compounds that pass electron from one
to another via redox reactions coupled with the transfer of proton across a membrane to
create a proton gradient that drives ATP synthesis. (Produces most ATP)
Glycolysis - Answer - The process in cell metabolism by which carbohydrates and
sugars, especially glucose, are broken down, producing ATP and pyruvic acid.
Fermentation - Answer - Fermentation is an anaerobic process in which energy can be
released from glucose even though oxygen is not available.
Oxidation - Answer - Specifically, it means the substance that gives away electrons is
oxidized
Ionic Bond - Answer - is the complete transfer of valence electron(s) between atoms.
(Strongest)
Covalent Bond - Answer - also called a molecular bond, is a chemical bond that
involves the sharing of electron pairs between atoms. (Middle Strength)
