Which sentence correctly describes structures that cells move?

(select all that apply.)

microfilaments use a cycling motion.
microtubules use rocking actions.
cilia use wavelike actions.
flagella use a whiplike motion.

The correct answer will be options- Cilia use wavelike actions and Flagella use a whip-like motion.

Explanation:

The cell movement is the important characteristic feature of the cell which allows the organism to perform various functions.  

The cell movement allows the cell in reproduction like the sperm cell posses a long flagellum which uses whip-like motion to swim and cause fertilization. Similarly, the hair-like extensions of the membrane called cilia allow the movement of substances through wave-like motion is the body of the organism like the transport of the oocytes on the female tract.

Thus, the selected options are the correct answer.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
