The addition of dynactin caused dynein to travel farther along the micro tubule.
<u>Explanation:</u>
Dynein is a family of cytoskeletal motor proteins that move along micro tubules in cells. They convert the chemical energy stored in ATP to mechanical work. Dynein transports various cellular cargo, provides forces and displacements important in mitosis, and drives the beat of eukaryotic cilia and flagella.
Dynactin is a 23 sub unit protein complex that acts as a co-factor for the micro tubule motor cytoplasmic dynein-1. It is built around a short filament of actin related protein-1.
Marsupials began to migrate to Australia and New Zealand from North America in the late Cretaceous or early Tertiary period. The route of migration crossed Antarctica and into Australia.
The grass feeds the herbivores and the omnivores, such as rabbits an other smaller animals. Then those creatures produce energy after consuming the grass. Then whatever predator that eats them gains the energy that the smaller animal had made from the grass. So therefore the grass gives the beginning of the food chain energy, that is later consumed by the bigger creatures.
