The deserts are actually one of the most common and widespread landscapes on the planet Earth. The deserts, combined of all types, are covering around 33% of the landmass, thus one third of the whole landmass on the planet.
These multiple types of deserts, like the hot and dry desert type, cold desert, coastal desert, semiarid desert. All of them have their own unique characteristics that define them more specifically. The hot and dry deserts are the ones that are hot throughout all of the year, also being located deeper into the mainland. The cold deserts are found in the Northern Hemisphere, they have hot summers and very cold winters. The coastal deserts are located along the coasts, so despite being very dry, they do tend to have high humidity. The semiarid deserts are deserts that are not as dry as the other types, they receive more rainfall, though that happens just in few days of the year, so they are dry for the most of it again, with the biggest difference being that they have slightly more vegetation.
A genetic mutation results in the offspring of two butterflies being a different color. There is no evidence of biological evolution in this.
In populations of organisms, biological evolution is the change in hereditary features through successive generations. When diversity is added to a population through gene mutation or genetic recombination or removed by natural selection or genetic drift, features undergo evolutionary alteration. the gradual genetic change within a population. What is the most likely outcome if two species rejoin after many generations if allopatric speciation has place after a population split into two different populations?

D. It provides information about the subject of an experiment.
Background research is research prior to conducting an experiment.
Explanation:
Background research is important so as to fully understand the variables that are being controlled and tested in an experiment, and their relationships that will give insights into how to design the experiment. The background research is also important in identifying the research problem setting up of a good hypothesis.Background research also reduces the rate of failure of an experiment due to proper preparation.
