Question:
Which statement best explains how Sarah Zielinski introduces and develops her points in the article about Henrietta Lacks?
- Zielinski explains how her interest in the Henrietta Lacks story began then provides details about the first immortal human tissue sample and tells why it has been both important and controversial.
- Zielinski explains the need for using human tissue samples then introduces Rebecca Skloot who gives an account of her experiences of researching the origin of the HeLa cells.
- Zielinski explains how the first immortal human cells were found then provides Rebecca Skloot’s answers to questions about the importance of using human tissue samples, the Lacks family’s responses to learning of its link to the HeLa cells, and the issues arising from their discovery and use.
- Zielinski explains the importance of the first human tissue samples to life and their widespread use, the reason for the confusion about those samples as well as the ethical issues faced by the Lacks family after learning they had not shared in profits from the sale of the HeLa samples.
Answer:
The correct answer is number 3
Explanation
The article devotes the first three sentences to describing how the Immortal cells came to be. In sentence 4, she makes reference to a book by Rebecca Skloot titled <em>The Immortal Life of Henrietta Lacks. </em>The book explains the history of Henrietta's cells and its impact on Henrietta's family as the medical world.

The examples of engineering controls is Biohazard waste containers and Spill clean up kits.
What is engineering controls?
An engineering controls is a workplace process that protect workers by removing hazardous conditions or by placing a barrier between the worker and the hazard.
An example of engineering controls is installation of exhaust ventilation to remove airborne emissions to shield the worker.
Hence, the examples of engineering controls is Biohazard waste containers and Spill clean up kits.
Therefore, the Option C and D is correct.
Answer:
True
Explanation:
The hyperbolic elements for the spacecraft Voyager 1 launched by NASA in 1977 flew by Jupiter and Saturn and continued to explore beyond the solar system into the interstellar space. Trajectory engineers produced data on this journey that indicated a value of eccentricity less than 1 from Earth reaching Jupiter and an eccentricity value greater than 1 for the journey past Jupiter that increases positively as the spacecraft advances to reach Saturn and beyond.
