cilia, pseudopodia
flagella; cilia
microtubules; flagella
microfilaments; microtubules

The correct answer will be option-flagella; cilia.

Explanation:

The cellular movement and the movement of the environment surrounding the cell is accomplished by the hair-like projections which arise from the plasma membrane called the flagella and cilia.

The flagella are the long hair-like projections which help in the movement of the cells like sperm cells and the cilia are the short hair-like projections which help in the movement of the surrounding material of the cell.

Thus, the option-flagella; cilia is the correct answer.

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves
