Ciliates are required for a paramecium to survive in its environment
Explanation:
The protists that are of single-cell is known as paramecium, especially found in the aquatic animal. They are long, shaped like slipper and body covered with cilia. They belong to the organelle group of Ciliates as their body has cilia covering it. This helps in their body movement in their environment of aqua.
Paramecia sometimes move in reversed direction of the beat of cilia, that causes turning and stopping of it. The structure of cilia helps the paramecia to move backward and then forward.
Paramecia have many organelles characteristic of all eukaryotes, such as the energy-generating mitochondria. However, the organism also contains some unique organelles. Under an external covering called the pellicle is a layer of somewhat firm cytoplasm called the ectoplasm
That is going to be C) adolescence because when one is an infant they don't know much and they are just learning, as a kid in our childhood. Kids just don't pay attention and want to do whatever. We would already know life skills as an adult so it is adolescence
