Paragraph list

These organisms can survive in this extreme environment because of A their unique genes and proteins.
The extremophiles that microbiologist Rick Cavicchioli and his team study love life extremely cold.
Understanding more about their DNA could help in the development of a variety of new technologies.
Extremophiles are organisms that thrive where other microbes (organisms that are so small that they're not visible to the human eye) don't dare venture, such as freezing lakes, the water core of nuclear reactors and toxic waste dumps.
They live at the bottom of Ace Lake in Antarctica, where there is no oxygen and the average E temperature is 1°C.

First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main topic of the text. It gives a broad overview of what extremophiles are and where they live. This follows the rule of Topic Sentence. It does not use any referencing phrases that need prior context. Why other lines are not chosen? The other paragraphs are not chosen as the first sentence because they do not meet the criteria for being independent. For example: - Paragraph 2 starts with 'The', which refers back to the previous information. - Paragraph 3 starts with 'They', which is a pronoun that needs context. - Paragraph 4 starts with 'These', which also refers back to something mentioned before. - Paragraph 5 starts with 'Understanding', which does not stand alone without context.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it wraps up the discussion about extremophiles. It gives a conclusion about the importance of studying their DNA. This follows the rule of Conclusive Words, as it summarizes the main points of the text.

Paragraph pairs:

  • Pair 4 (Paragraph 4 → Paragraph 5): Paragraph 5 connects with Paragraph 4 because it discusses the importance of understanding the DNA of these organisms. The topic of survival leads to the need for research on their DNA. This follows the Logical Order.
