What process takes place within mitochondria? A. cellular respiration B. photosynthesis C. protein assembly D. reproduction User: How are flagella and cilia alike? A. Both help to produce energy. B. They break down substances. C. They assist with movement. D. Both are for storage of cellular materials.
Weegy: Cilia and flagella are the motile appendages of eukaryotic cells. They are thick, flexible structures that exhibit a beating motion and project from the surfaces of many cells. [ A cell having one or a small number of appendages can be identified having flagella (singular, flagellum) if they are relatively long in proportion to the size of the cell. If the cell has many short appendages, they are called cilia (singular, cilium). Cilia and flagella have the same internal structure, but differ in their length, the number occurring per cell, and mode of beating. They are axonemal in shape, formed by a main cylinder of tubules that are approximately 0.25 mm in diameter. The axoneme has a pattern of "9 + 2" consisting of nine outer doublets of tubules and two additional central microtubules (the central pair). Cilia are about 2-10 mm long, while flagella are much longer, ranging from 1 mm to several millimeters, although they are most commonly 10-200 mm. They are both intracellular structures, bound by an extension of the plasma membrane. Both cilia and flagella are used by cells to move through watery environments or to move materials across cell surfaces. Read more: ] (More)

The solution to the equation of 4 + 3s – 9s = 22 is s=-3.
4 + 3s – 9s = 22
4-6s=22
-6s=18
s=18/-6
s=-3.

2q + 18 = -5q - 3
2q + 5q = -3 - 18
7q = -21
q = -21/7
q = -3
