Answer:

Bacterial DNA is a double-stranded helix that has to separate its strands during replication. The unwinding of DNA strands at the replication fork creates twists farther down the helix that need to be relaxed by DNA gyrase. Ciprofloxacin inhibits this enzyme to block DNA synthesis and stop the deadly bacteria from growing.

Explanation:

DNA which stands for deoxyribonucleic acid is the molecules that stores genetic information in most living organisms. For successive reproduction to take place as well as growth to occurs in organisms, the genetic information stored in the DNA must be copied into new cells. This is achieved through the process of DNA replication.

DNA is a double-stranded molecule that is helical in shape. For replication to occur, the double strands has to be separated so that the information stored within can be accessed and then copied. DNA helicases are enzymes which are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied. The unwinding of DNA strands at the replication fork creates twists farther down the helix that need to be relaxed otherwise, the DNA strands will break. The enzyme responsible for relaxation these twists is known as DNA gyrase. Thus, any drug like Ciprofloxacin than inhibits DNA gyrase will block the DNA replication process in bacteria thereby stopping the growth of the bacteria.

Luba_88 [7]
An organism is d. a group of organ systems working together.

An atom goes into a molecule which goes into a cell which goes into a tissue which goes into an organ which goes into an organ system which goes into an organism. 

Organs working together with other organs create a system of organs or an organ system. Something like this helps keep a human body, for example, functioning since everything relies on each other. 

Remember that if your respiratory (breathing) system and nervous (brain) system did not work together, you would not be alive, and therefore no longer a living organism.
