Phylogeny is like what? - ANSWERSA family tree. Everyone has parents and they too have parents What is phylogeny? - ANSWERSThe evolutionary history of a species or group of related species Basic Law of Biology to lead to phylogeny - ANSWERSEvery living thing came from some parental genetic material. And those living things are MODIFIED descendants of their parents genetic material. What makes us not copies of our parents? - ANSWERSMutations and no clone chromosomes What is the most c...

All living organisms on Earth are related through - ANSWERSCommon Ancestry Five-year voyage around the world. This ship sailed from England, around the tip of South America, to the Galápagos Islands, around the southern coast of Australia and Africa, and back to England. During this journey, Darwin collected thousands of samples: plants, animals, fossils, and rocks. He made careful and important observations about the organisms he encountered. - ANSWERSHMS Beagle Darwin surmised that bird...

Frameshift mutations are more likely to have an impact at the phenotypic level because they: Question 8 options: are the result of a change in a single nucleotide. are the result of exposure to radiation. produce a protein having no function. are mobile pieces of DNA. - ANSWERSproduce a protein having no function The advantageous "attributes" to which Darwin refers are now known as: Question options: traits. genes. alleles. chromosomes. - ANSWERStraits Adapt...

Natural Selection: - ANSWERS1. All species are capable of producing offspring at a faster rate than food supplies increase 2. Because in each generation more individuals are produced than can survive, there is a competition for limited resources 1. There is biological variation in all species 2. Some individuals in the population will possess traits that allow them to survive and reproduce more successfully than others in the same environment 3. Environmental conditions determine whet...

What are the 2 commonalities of all life? - ANSWERSall life possesses DNA/RNA And All life evolved Evolution: - ANSWERSdescent with modification. Change in the properties of populations of organisms, or groups of such populations, over the course of generations Evolutionary biology applies in? - ANSWERSHealth sciences, Agriculture, Natural products, Conservation and environmental Management, and in understanding ourselves. Entertainment Evidence of Evolution - ANSWERSMicro, Speciation,...

How do we read and interpret a phylogenetic tree? - ANSWERSTo interpret a phylogenetic tree, one should first examine the lengths of the lines. The phylogenetic trees are usually graphed over a change in time, and thus the lines that extend the farthest overtime relate to the extant species. Extant species include the species that are currently alive and reproducing. If the lines end early these species can be determined as extinct, no longer alive and reproducing. Next, one can follow these lin...

biological evolution - ANSWERSan inherited change in a group of organisms through time phylogenetic tree - ANSWERSa graphical representation that shows that organisms show various degrees of similarity because they are, to various degrees, related by genealogy cultural evolution - ANSWERSmuch faster than biological evolution; includes written/spoken language, tool use, art/religion, teaching Jean Baptiste Lamarck - ANSWERSthought inheritance of acquired characteristics was because indiv...

2 commonalities of all life - ANSWERS1. all life posses DNA and RNA 2. all life evolved evolution - ANSWERSdescent with modification evolution changes properties of - ANSWERSpopulations or groups, over generations evolutionary biology has applications in - ANSWERShealth science, agriculture, natural products, conservation and environmental management, understanding ourselves, entertainment evidence of evolution in micro evolution - ANSWERSchange through time evidence of evolutio...

Hox genes (homeobox) and Homeodomain Polypeptide - ANSWERS-A group of genes that regulate development in multicellular organisms; this includes cell differentiation & morphogenesis. -Hox a gene also acts as a switch that turns on and off. Deme (interbreeding group, or evolutionary population) - ANSWERS-Population unit or panmictic unit (mendelian population) -A sub-population (a smaller group within the population that can freely interbreed) Evolution - ANSWERS-Change in a kind of ...

A group of individuals of the same species that occupies a given area is referred to as a(n) ___. A. Community B. Population C. Ecosystem D. Biome - ANSWERSPopulation Ecology is the scientific study of the relationship between ________and their environment. A. Individuals B. Population C. Ecosystem D. Organisms - ANSWERSOrganisms In a field experiment, an ecologist measures the effects of nitrogen on productivity, plotting data for nitrogen on the x-axis and productivity on the y-...
