Solved in 2 steps
- You are studying two variations of banana slugs. They have similar coloration and live in the same habitat. Although they are physically able to mate, there are no offspring that survive embryologic development. What can you conclude about the banana slugs? * Pre-zygotic barriers have forced them to be separate species. They are in Hardy-Weinberg equilibrium. Microevolution is occurring in both variations. They are two separate species. Two species of toads are reproductively isolated due to the fact that one species mates in early summer and one in late summer. Both species of toads evolved from a common ancestor. What type of speciation occurred?* OAllopatricSympatric speciation by allotetraploidy has been proposed as acommon mechanism for speciation. Let’s suppose you were interestedin the origin of certain grass species in southern California.Experimentally, how would you go about determining if some ofthe grass species are the result of allotetraploidy?which 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.
- Consider two species that diverged whilegeographically separated but resumed contactbefore reproduction isolation was complete. Predictwhat would happen over time if two species matedindiscriminately and a. hybrid offspring survived and reproducedmore poorly than offspring from intraspecificmating or b. hybrid offspring survived and reproduced aswell as offspring from intraspecific mating.Provide an example for each to illustrate yourpoint.A- the two nematode populations have undergone complete speciation B-  individuals reared on different bacteria produce offspring that have a better chance of survival C- The populations appear to be most likely in the process of speciation D- all individuals were equally reproductively successful regardless of mate combinationWithin a population of sunflowers, a new individual has a novel dominant mutation that causes it to flower 4 months earlier than the rest of the population. That sunflower survives and successfully self-fertilizes, leading over time to a novel population that evolves larger leaves and smaller flowers. This new population does not interbreed with the original population, although they are found in the same areas. This is an example of Allopolyploid speciation O Behavioral isolation O Allopatric speciation O Sympatric speciation O Adaptive radiation
- It has been found that many insect pest populations have become more resistant to pesticides over time. How might this have occurred? O The individual insects who were naturally resistant to the pesticide were able to reproduce and pass on their genes. This created future generations of insects that were more naturally resistant to the pesticides. O Individual insects decided they did not like the pesticides and went to the doctors O The chemical pesticides given to insects have mutated due to climate shifts and no longer work. O The pesticide killed off the insects and new ones moved into the region, who have not been exposed to the pesticide yet.n 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 data(a) Gryllus pennsylvanicus prefers sandy soil. (b) Gryllus firmus prefers loamy soil. Based on the information above what kind of reproductive isolating mechinism is being exhibited by the two cricket species? A. Ecological isolation B. Mechanical isolation O C, Gametic isolation D. Temporal isolation O E. Behavioral isolation
- Our species, H. sapiens, derived from: OH. floresiensis. ●H. ergaster. O H. habilis. OH. rudolfensis.

True O FalseCan speciation occur without complete physical separation of populations?
