Doctoral student is studying the genetic make up of a species of jellyfish that occurs at low middle and high latitude regions of the pacific ocean on an ocean graphic expedition she collects specimens of the jelly fish throughout its range. Upon returning to the laboratory at the University and assistant places all of the jellyfish and aquarium with an average temperature of approximately 20 C. After a few days he notes that almost 2/3 of the jellyfish have died using the figure below how would you explain which jellyfish likely make up the bulk of the survivors and what the mistake was.
A. The survivors were likely collected from the dark gray areas on the map those from other regions could not adapt
B. The survivors were likely collected from the light gray areas of the map those from the other regions cannot adapt
C. The survivors were likely from the black areas of the map but had the most advantageous genes of those collected
D. The survivors were likely from the black areas of the map adapted to difference in the temperature in the laboratory.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.

explanation:

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.

the growth of the plants is affected by the heat of the light. what is the student doing?
