The cytoplasmic streaming can be defined as the movement of the cytoplasm inside the cell. This movement of the cytoplasm helps in the delivery of the metabolites, organelles, and nutrients to all the parts of a cell. The cytoplasmic streaming, which is also known as cyclosis, occurs at the same rate throughout the cell and moves in the direction of the light.
Hence, the answer is 'moves at same rate and towards light'.

<span>#1) Find one example of convergent evolution among the Caminalcules.
Answer: The best example that I can think of is the wings on a bat. They have elongated fingers that make up most of the wings. They use skin that is stretched between their fingers to create the area that is required to produce lift. The arm bones in the bats and birds are homologous to one another, but their wings are the result of convergent evolution. Birds and bats have aerodynamic bodies which allow them to pass fly through the air efficiently. Also some insects, like dragonflies, have aerodynamic bodies, but bees and beetles don’t.
