One G is equal to the normal pull of earth’s gravity on the body.Modern-day ride designers employ a steady stream of advances to create new, unique, and safe amusement rides and attractions.Amusement ride manufacturers applied the industry's biodynamic knowledge (collected over years) as it relates to g-forces to the design and construction of rides to ensure a safe experience.While technological gains have led to the development of bigger and faster rides, overall g-force levels have generally remained the same because riders’ tolerance levels have not changed.
Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes.
They start as single cell orginisms then they evolve from there.
hope that helps
