Hello, I really need help with these multiple choice questions. I have tried them and got some of the answers, but I would like to make sure I did them correctly. If anyone could help I would greatly appreciate it. Also please do not say I shouldn't ask this question, or it's stupid. I really need help.
1.) The peppered Moth is a light colored moth that is gray with black speckles found in many fields of England. A naturally occurring mutant is all black. From the 1800's to 1950's the number of all black moths in the population was rising because:
a.) Increased mutation
b.) Black moths were well suited to hiding on light tree trunks
c.) Pollution better suited black moths to hide
d.) More predation on black moths
2.) When glaciers separated populations of brown bears from each other, each group isolated and could no longer intermix.. because
a.) Reproductive isolation
b.) Speciation
c.) Geographic isolation
d.) Convergent evolution
3.) The Muntjac of South America and the Diuker of Oceania are deer like creatures that have both wedge like heads, and powerful black legs to propel them through dense brush. The fact that they are similar in body plan, and have evolved from related ancestors makes them an example of:
a.) Divergent evolution having homologous structures
b.) Divergent evolution having analogous structures
c.) Convergent evolution having homologous structures
d.) Convergent evolution having analogous structures
4.) Which of the following is an example of divergent evolution?
a.) The geographic isolation of two orchid populations
b.) Darwin's flinches
c.) The similar characteristics of dolphins and sharks
d.) The wings of bat and the wings of insects
5.) Although the seal and the penguin have both streamlined, fish-like bodies with a layer of insulating fat, they are not closely related. Their similarities result from
a.) Homologous evolution
b.) Convergent evolution
c.) Adaptive radiation
d.) Divergent evolution
6.) Which of the following is TRUE in the bottleneck population?
a.) There is greater genetic variation within the species
b.) There is an increase in population

a.) Selectively breed plants and animals to better serve
b.) Breeding dogs to get that 'perfect' pooch
