BIOL 180 Exam MOD 002 Concepts and Questions 2023 GRADED A+ and VERIFIED What is the most important difference between species richness and species diversity? correct answers Species diversity takes species number AND relative frequency into account. What is the key difference between primary productivity and net primary productivity? correct answers Net primary productivity represents just the energy used to build biomass. "Diversity leads to stability." This slogan claims that ecosy...

Discrete trait correct answers *Inherited trait* that exhibits *distinct phenotypes* Quantitative traits correct answers A trait that exhibits *continuous phenotypic variation* Asexual reproduction correct answers *Reproduction* where offspring inherit DNA from only *one parent* E.g. binary fission, budding and parthenogenesis Sexual reproduction correct answers Any form of reproduction in which *genes* from *two parents* are combined via *fusion of gametes*, producing offspring that a...

What is a synapomorphy? correct answers A trait that is similar in two or more species because it is derived from a trait that existed in a common ancestor. Why do synapomorphies arise during evolution? correct answers When a new species begins evolving independently, novel traits arise which are then passed on to its descendant species. What does it mean to say that one phylogenetic tree is more parsimonious than another? correct answers Fewer changes have to occur to make the origin of t...

monophyletic group correct answers a common ancestor and all of its descendants out-group correct answers a taxon that is closely related to a monophyletic group but not a part of it what is the difference between homology and homoplasy correct answers whether or not traits were inherited from a common ancestor synapomorphy correct answers a trait that comes from a common ancestor and identifies a monophyletic group parsimony correct answers the simplest explanation is the best wh...

metapopulation correct answers a population of populations connected by migration replacement rate correct answers average fertility required for each woman to produce exactly enough offspring to replace her and her offspring's father community correct answers all species that interact in a certain area commensalism correct answers (+/0) one species benefits but the other is unaffected competition correct answers (-/-) individuals use the same resources - lower fitness for both c...

special creation correct answers 1. All species are independent 2. Life on Earth is young 3. species are immutable Pattern correct answers summarizes observations about the natural world (what happened) Process correct answers a mechanism that produces the pattern/set of observations (how it happened) Darwin's 4 Postulates correct answers 1. variation exists within a population 2. some traits are heritable 3. survival/reproductive success is variable 4. the subset of individuals t...

pure line correct answers In genetics, a strain that produces offspring identical to the parents when self-fertilized or mated within the strain. Pure lines are homozygous for the gene under study. hybrid correct answers the offspring of parents from two different strains, populations, or species parental generation correct answers the adults used in the first experimental cross of a breeding environment F1 generation correct answers first filial generation. The first generation of offs...
