HELP questions about Charles Dawin and evolution?
1.) a. more offspring are produced than can possibe survive BUT, it's the variation of the characteristics in the offspring ("d") that may determine which survive and which don't.





2.) I would say b.mating that is not random - if females chose males that are larger, more colorful, louder, etc. it would perpetuate those traits over others that weren't selected in the offspring. But you would already have to have mutations in the population to produce those differences, so "d" also applies.





3.) c. small particles of sand silt and clay is the closest to being right, but it doesn't include all the possibilities (sand, precipitated chemicals)





After looking at these questions, I can see why you're confused!
