Answer:
The answer is B. The most recent common ancestor.
Explanation:
Cladograms are used to illustrate relationships related to morphological and evolutive traits. So then, in a cladogram when organisms are closely related, they appear closer in the branches. Common branches and nodes mean close relationships and common ancestors on a scale of time.
The correct answer is option (B) continental drift.
Continental drift is a theory explaining the movement of the earth’s continents over the geological time scale, drifting across the ocean bed. It was proposed by Alfred Wegener in 1912. Similar plants and animal fossils found around the shores of the different continents suggests that these continents were once joined as a single super continent named Pangaea. This Pangaea broke up long ago and the continents moved to their current positions. The ancient fossils of the same species of plants and animals were found on rocks of the same age but on the continents that are now widely separated.
I assume the answer is man-made, correct?
<span>DNA is responsible for passing information for making protiens. DNA is linked with chromosomes, which are duplicated in every cell of the organism's body. Depending on the mode of reproduction, it either undergoes meiosis to produce haploid gametes, which are fertilized and become diploid, and hopefully mature to become reproductive adults or undergoes mitosis to form a fully-fledged adult which eventually drops off the parent and goes on to produce other adults</span>
