Which of the following is an example of the bottleneck effect?
Cheetah populations reach their lowest levels with reduced diversity and as they rebound are so genetically similar they appear to be inbred.
Affected individuals with blue skin can trace their ancestry back to one of the first settlers in the region.
The environment of a fox population changes and over time foxes who are white survive and pass on their genes to their offspring.
Humans choose two dogs they like the characteristics of and breed them together.
Tall kelp have a distinct advantage over shorter kelp in receiving needed sunlight in their ocean environment

Some female peacocks prefer males with large, colorful tales while other female peacocks prefer males with no tail at all. Females are now mating only with the tail they prefer. What type of reproductive barrier is this?
behavioral isolation
hybrid sterility
temporal isolation
mechanical isolation
Most of the time this post zygotic barrier is seen in plants and affects the offspring's offspring. In other words, the initial hybrids are perfectly strong but when the offspring try to reproduce that next generation is stunted or sterile.
Reduced hybrid fertility
Reduced hybrid viability
Hybrid breakdown
All of the above
Punctuated equalibrium or gradualism?

Gradualism
Punctuated equalibrium or gradualism?
Punctuated equalibrium
Gradualism

They are all multicellular
Protists are increadibly diverse
What is NOT true about protists?

Archaeplastida
Opisthokonta
Amoebozoa
Impossible! Those are in two different supergroups!

Archaea
NOT a difference between bacteria and archae
Bacteria are found everywhere; archaea are found in extreme environments
Bacteria have "normal" cell membranes; archaea have unique cell membranes
Archaea genes are more closely related to eukaryotic genes; bacteria are not
All of these are true differences between bacteria and archaea
