Answer:
Qualitative research seeks to understand why people react and how they feel about a specific situation. Quantitative research measures numerical results to help predict possible outcomes. In other words, qualitative research is concerned with "why," whereas quantitative research is concerned with "what."
Explanation:
The answer is a. Pleistocene.
A group of large animals that lived during the Pleistocene is called Pleistocene megafauna. This group included mammoths, giant sloths, mastodons, cave bears, saber-toothed cats, etc. The extinction of these animals happened also in Pleistocene. The reasons for their extinction could be hunting by the humans, climate changes, or impact of asteroides.
They might have a common ancestor.
Let's calculate the difference in nucleotides. The number of difference multiplied by rate of mutations will help to determine how long ago these two species shared a common ancestor.
Species A: GTACCTAAGTTCACCGAATT
Species B: GAACCTAAGGGCACCGAACT
These species differ in 4 nucleotides.
This number should be multiplied <span>by </span>the rate of mutations
The protons in the nucleus
