If one sample of food contains 200 calories and another contains 300 calories, which statement applies?

a. the 200 calorie food contains more potential energy than the 300 calorie food
b. the 200 calorie food contains less potential energy then the 300 calorie food
c. the 200 calorie food contains the same potential energy as the 300 calorie food
d. the potential energy of both foods cannot be determined unless they are combusted in a calorimetr

If one sample of food contains 200 calories and another contains 300 calories, then the 200 calorie food contains less potential energy than the 300 calorie food. The correct answer between all the choices given is the second choice or letter B. I am hoping that this answer has satisfied your query about and it will be able to help you.

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.
