I'm at a loss between A & C but I'm not sure, I'd go with A
Answer:
a. positive; negative
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.
The telescope I feel like is one of the most important one
Answer:
The correct answer is D. How closely related the two species are to each other
Explanation:
Genome maps of every individual is unique. Genome map is the order of sequence of nucleotide which is present in an organism. Comparison of genome map allow the scientist to know how much closely related two organisms are.
The map of two individuals of the same species is almost the same. Similarly, the two same species have a more similar genome map than two distantly related species because they share most recent common ancestor.
For example, humans and chimpanzees are more similar than other apes so 96% of the genome are identical between them. So the right answer is D.
Answer:
Instead of oxygen a creature would also need nutrients. Simple everyday things like water and food.
Explanation:
Although it is kind of impossible to live without oxygen. There are organisms on the earth who do not need it and can survive. They metabolize hydrogen or methane or a number of other compounds.
