How is the Maunder minimum related to climate?A. Changes in the Earth’s tilt correlate to changes in climate.B. The Maunder minimum is unrelated to climate.C. Changes in the Earth’s orbit correlate to changes in climate.D. Unusually low sunspot activity correlates to unusually cold climatic events.

Answers

I think the correct answer is D. The Maunder minimum is related to climate because it correlates to unusually cold climatic events. This is an event that happened sterting in 1645 to 1715 where very few sunspots were observed. It is also known as prolonged sunspot minimum. During this event, Europe and North America experienced colder temperature than what was usual.

During the reproduction of a species of butterflies, a mutation occurs that makes the offspring more visible to predators. Is this a positive or negative mutation? How do you predict this mutation will affect the long term survival of the species? Justify your response in two or more complete sentences.

Answers

This is an example of negative mutation. Negative mutations produce a phenotype that acts antagonistically to the wild-type phenotype. On the other hand positive mutation produce a phenotype that acts synergistically to the wild-type phenotype.

The negative mutation will negatively affect the  long term survival of the butterfly species as the mutation makes the new butterfly offsprings more visible to predators.
