Artificial selection is a form of selection in which humans actively choose which traits should be passed onto offspring. humans have used selective breeding long before darwin's ideas on natural selection and the discovery of genetics. farmers chose cattle with beneficial traits such as larger size or producing more milk, and bred them and although they may have known nothing about genes, they knew that the beneficial traits could be inherited. the farmers selected for certain traits in their cattle and probably noticed that the offspring were becoming more and more productive with each generation. most breeds of household dogs that exist today are due to artificial selection. the original bloodline is from wolf-like animals that were domesticated and bred for more docile traits. now we have a huge range of dog breeds.

hunting is a form of artificial selection. defend or refute this statement based on the principles of artificial selection.
a)hunting is not a form of artificial selection but a form of natural selection. the strongest survive; the weakest are culled and killed. the superior traits are passed down to the next generations. b)hunting is also a form of artificial selection, with the genes that humans want (i. e., the buck with the most points on his antlers), is bred into the gene pool, allowing the them to pass on to future generations. c)hunting is a form of artificial selection. hunters tend to weed out the weakest of any population, deer, fish, quail, and leave the stronger. the traits of the stronger members are then passed down to future generations. d)hunting is a form of negative artificial selection, with the genes that humans want (i. e., the biggest buck or largest fish), being removed from the gene pool, allowing the less wanted genes to pass on to the next generation.

Astudent from one of the research labs is having trouble preparing a slide for examination and photographing. the bacterial slide that he has brought to you was prepared using a commercially purchased stain. he has asked for your in determining what he is doing wrong so that he can change the lab protocols and continue on with his project. after examining the slide under oil immersion, you determine that no bacteria are present even though the student is able to show you the culture he used to make that slide that has visible growth in the liquid medium. which of the following statements does not explain the fact that there are no bacteria present on the student’s slide? by not allowing a glass slide to completely air dry before heat fixation, the flame will cause the surrounding water to boil and this will damage the bacterial cell. overheating during the fixation step boiled the water within the bacterial cells and resulted in the cells bursting. insufficient heating of the slide did not drive out the thin layer of water and this resulted in minimal bonding between the bacteria and the glass slide. rinsing with alcohol during the washing step stripped the bacteria off the glass slide. rinsing with alcohol during the washing step stripped the bacteria off the glass slide.
