I think it’s the 2 one not sure though
It's called COMPETITION because several animals fight for the same resource.
Pseudo vacuoles are not true organelles since they are just air bubbles which do not possess tonoplast and cell sap like real vacuoles. But they do help by increasing buoyancy of cells.
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.
