If a local climate grows wetter and a river splits the habitat in two, a single population of organisms can be split into two separate populations. These populations will have different evolutionary paths over time, to the point where they may no longer be able to interbreed. What is this an example of:
A. bottleneck effect
B. allopatric speciation
C. Founder's effect

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

you can have just about every answer you can think of

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.
