The theories on the expansion of the universe ?

1 answer:

5 0

Theories are often the best explanations of natural phenomena we currently have. Yet, what one has to realize is that science is ever changing. That is why (B) is the correct answer, as new examinations, experiments, and discoveries could change some of these well-accepted theories. There is no way to "harm science" with viable observations and discoveries so (A) is incorrect. Answer (D) is also wrong since there is no assurance that a theory will never change in the future as they are merely accepted hypotheses. Answer (C) is not the best answer since theories are usually well supported and wouldn't be veritable if every examination proved flaws.

Hope this helped! :)

Which molecule is active during the last step of DNA replication?

stepan [7]

Correct answer: Option D- DNA ligase

Explanation: In option A, thymine is a nucleotide, so it is present throughout the replication process, wherever it is required. It is added to the newly formed DNA. In option B, Helicase enzyme is active during initiation and elongation stage, as it facilitates the opening of the winded DNA strands. Option C is nucleotidase and it has no role in DNA replication. So, the correct answer is DNA ligase, which is option D.

The okazaki fragments formed during DNA replication are sealed at the end. And in this step, DNA ligase is used. It catalyzes the formation of phosphodiester bond between the nucleotides of okazaki fragments. So it is the last active molecule of the process.

I think the answer is B, the interpretation of specific events as threatening or challenging. According to Hans Selye stress is a body's nonspecific response to any demand made on it, physical arousal to events seen as threatening, and mental arousal to events seen as challenging. However, there are effective strategies to cope with stress which include a sense of humor, relaxation, social skills, and social support.
