Based on the data in the graph, the number of plant species in the ecosystems around Mount St. Helens before the blast was about 150
25
200
275

The year that the large eruption occurred, the number of plant species dropped to about
25
200
50
150

last - If Mount St. Helens were to have another large eruption today, the number of species in the ecosystems around Mount St. Helens would most likely

decrease
stay the same
increase

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.

artificial selection

this occur when man select base on their intelligent
