  2. car a and car b are moving in opposite directions.
  3. car a is moving faster than car b.
  4. car a and car b started at the same location.
  5. car a and car b pass each other at the crossover  point on the graph.  time (s)

Solution -

The motion of any object is represented by  position-time In such graphs the position of an object is fixed for any starting point on the y-axis and time on the x-axis.

The slope of such curves determine the velocity of the object at all its position within the graph. The steeper the slope is, the faster the the object is moving.

Almost all the South American and Central American
Vedmedyk [2.9K]

Answer:

O founder's effect

Explanation:

A founder effect can be defined as the loss of genetic variation when a new population is established from a few individuals. This process is known to increase the frequency of particular gene variants (alleles) at different <em>loci</em> when they are selectively neutral (or nearly neutral), and thereby such genes are fixed by genetic drift (i.e., through the random sampling of founder individuals). Interestingly, it has been discovered that the majority of South American and Central American Indians are nearly exclusively in the O blood group, which has been further associated with random genetic drift and a founder effect.
