Solnce55 [7]

Endorphins are brain chemicals known as neurotransmitters which are released when the body feels a certain amount of stress and pain. Endorphins alter the communication of pain in the body by interacting with the opiate receptors and blocking the synapse so that signals cannot be sent to the brain in order to reduce an individual perception of pain.

Which of these best describes genetic drift? A) The movement of alleles between population B) Random fluctuations in the gene fr
exis [7]
The correct answer is B.
Genetic drift is one of the four evolutionary mechanisms. It changes the frequency by chance, aka at random.
For example. if you have 100 frogs in the population, 20 red, 20 green and 60 yellow, not all of the alleles are going to be passed down to the next generation because a portion of the population can be affected by a random event such as the flood. So, if the flood accidentally kills 20 red frogs, none of the offspring are going to be red by chance.
