The answer is A, a mountain building.
The two faces of the book represent the tectonic plates
As he presses them towards each other he is modeling a convergent boundary, and mountains are an affect of convergent plates.
The answer is A because in the process of mitosis and meiosis chromosomes are single-stranded groups that are condensed to chromatin when the process of division of cells chromosomes replicate to make sure that the new daughter cells received the correct number of chromosomes
The answer is false, liquid molecules continue to move even after the concentration is uniform.
Diffusion happens because there’s a concentration gradient between the dye and the water, therefore dye molecules moves to the water area. But note that this is only the net movement of the molecules, which means, even if more molecules are moving towards water, there are still some dye molecules that are moving in the opposite direction.
So, after the concentration is equal, the motion of the dye molecules does not stop, they still move in random directions, but there’s no net movement instead, as there’s no concentration gradient. Remember molecules are always moving in all directions , it just depends on whether there’s a net movement or not. If there’s no net movement, the amount of molecules moving to each and every direction is always equal.
Answer:
RANDOM MATING
Explanation:
random mating
The Hardy Weinberg principle of genetic equilibrium defines that gene and allelic frequencies will remain the same among the generations in an infinitely large interbreeding population. In this population the mating among the members of the population is random and no selection, migration and mutation will occur.
