Which is a result of a seasonal change (meaning a change that happens over and over at a certain time of the year)? a. grizzly bears move north when houses are built. b. the arctic fox changes the color of its coat when snow falls. c. birds migrate when a forest is destroyed. d. the carp avoids a polluted section of a lake.

The correct answer is option B. the arctic fox changes the color of its coat when snowfalls.

Explanation:

Seasonal changes are a change that takes place every year or a certain time of the year. It normally occurs due to the unfavorable weather or environmental conditions.

During snowfall, Arctic fox changes their fur color and in summers it changes back to the dark coat that helps in camouflage so they can help to hide from predators and prey.

Thus, the correct answer is option B. the arctic fox changes the color of its coat when snowfalls.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
