- Which of the following is not part of how we define a species? a. Its individuals appear different from other species. b. It is reproductively isolated from other species. c. Its populations can interbreed. d. Fertile offspring are produced.arrow_forwardn which situation would it make sense to use the morphological species concept? When you are able to collect data about how individuals in your study use their habitat, but you are unable to determine if they interbreed When working with fossils from extinct organisms When you only have genetic data about each organism in your study When you are not able to collect data about how individuals in your study use their habitat, but you are able to collect reproductive dataarrow_forwardwhich statement is false? 1)In the context of the evolution of senescence, the aphorism "live fast and die young" means that organisms with a more risky behavior will have a shorter life span. 2)Allopatric speciation is a type of speciation process that takes place in different geographic locations.arrow_forward
- The biological species concept is based on the assumption that species are reproductively isolated and do not share genes. And yet a number of organisms that are considered different species hybridize (mate and exchange genes). Hybridization between different species is more common in plants than in animals. Propose some possible reasons for this difference.arrow_forwardOf the following taxonomic categories which is the most inclusive (i.e. is the highest in hierarchy)? A. Order B. Subspecies C. Class D. Genusarrow_forwardWhich of the following traits is more associated with an Opportunistic (Equilibrial) species? Which of the following traits is more associated with an Opportunistic (Equilibrial) species? A. Short maturation time B. Producing offspring at many different times over the course of life C. Producing a lot of eggs at one time D. High juvenile mortality E. High level of parental carearrow_forward

What type of isolating mechanism is involved? Group of answer choices A. behavioral isolation B. gametic isolation C. mechanical isolation D. temporal isolation E. habitat isolationarrow_forward
- Explain the type of speciation (allopatric, parapatric, or sympatric) most likely to occur under each of the following conditions: A. A pregnant female rat is transported by an ocean liner to a new continent. B. A meadow containing several species of grasses is exposed to a pesticide that promotes nondisjunction. C. In a very large lake containing several species of fish, the water level gradually falls over the course of several years. Eventually, the large lake becomes subdivided into smaller lakes, some of which are connected by narrow streams.arrow_forwardWhich of the following statement about the outcome of the evolution of a new species through hybridization is false? a.The new species may have traits that allow it to inhibit environments different from both parental species. b.The new species is always an intermediate of the two parental species c.The new species may have greater genetic diversity and greater trait diversity than the parental species. d.None of the above What are the two ways of looking into evolution in detail? a.Micro frequency change and ascent with modification b.Genotypic and phenotypic modification c.DNA frequency change and inheritance modification d.Allele frequency change and descent with modification Natural selection increases the frequencies of advantageous alleles and decreases deleterious alleles' frequencies. What are the three categories of natural selection depending on the favored traits? a.Directive, selective and native b.Indicative, normative and fixative c.Directional, stabilizing and…arrow_forwardWhich of the following traits does not describe a r-selected species?
