Explanation:
Transcription is the process of forming an RNA molecule from a DNA template molecule. In this process, the strands of DNA separate and one serves as a template for RNA, while the other is inactive. At the end of the transcript, the tapes that have been split back together again.
The transcription process is divided into three steps: initiation, stretching and termination
During the stretching phase, transcription chain elongation occurs. In this phase the enzyme called RNA polymerase starts to move through the DNA molecule, unwinding its helix and producing an increasingly lengthened RNA molecule. The already transcribed DNA is rewound almost immediately, recomposing its double helix. This process is called the elongation phase.
During this process, it is believed that positive supercoils are generated ahead of the transcription bubble and and the negative supercoils behind it.

There are various diseases and disorders that could arise from high levels of saturated fat and specfically bad cholesterol. From the renowned, cardiac arrest, atherosclerosis, hepatic steatosis, neurological diseases like cerebrovascular diseases; ischemia and hemorrhagic stroke, disoriented weight size and gain -obesity is also caused by the high concentrations of fat and bad cholesterol.
These disorders and complications are just the few of the many possible outcomes of the mentioned imbalance of fat. How? because there is too much lipid for the body to process and metabolize thus, breach of homeostasis.

D
Explanation:
Zebra mussels can be a nuisance in novel ecosystems. When introduced in a non-native ecosystem with no natural predators, they reproduce rapidly displacing native mussels. Zebra mussels take up much of the algar that feeds the other native species hence starving them to death and causing their numbers to plummet. In addition, they attach to the other mussels and clog up power plants, that use the local water, water intakes.
