Explanation:

Molecular anthropology is a relatively recent branch, it refers to the study of biological phenomena (genetic study) at molecular levels, that is, biochemical, it allows us to understand and expand our knowledge about the evolution of the species and the complex phenomena of microevolution . It is closely related to other fields of anthropological study, among which we can mention primatology and genetics.Through molecular anthropology we are more aware of kinship, therefore, we can know human evolution over the centuries .

A velocity-time graph shows how<br> I<br> changes over<br> time.
stich3 [128]

Answer:

What does a linear velocity graph tell us?

The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).

What is an acceleration time graph?

A graph that shows acceleration plotted against time for a particle moving in a straight line. ... The acceleration-time graph is the graph y=a(t), where the t-axis is horizontal and the y-axis is vertical with the positive direction upwards.

graph shows changes in velocity of a moving object over time. The slope of a velocity-time graph represents acceleration of the moving object.
