Evaluation/Worksheet
Answer the following questions in the space provided. Remember to use complete sentences to demonstrate comprehension and understanding.
Based on the reading “immortality 2.0”, answer the following questions:
|Write a brief summary, three to five sentences, indicating the major concepts or ideas that the paper is proposing. |
|Answer: There are those who think of the human body more in terms of computers than in terms of biology. In comparing the brain to microchips,|
|it has been proposed that technology can extend the lives of humans indefinitely. If the human consciousness and physical processes can be |
|transferred to computers, then many forward thinkers believe that the body can be re-engineered to last forever. |
|Discuss the potential advancements as well as the concerns regarding the topic of the paper as it relates to the evolution of humans and |
|technology. |
|Answer: Transhumanism wants to copy people onto programs. Evolution has been our forward movement until today, but evolution seems to have |
|slowed down, and the brain is due for an “upgrade”. If this were possible, then perhaps man might live forever. Concerns that these ideas |
|elicit are that we already have too many people using the resources of the Earth. Singularity leads us to be concerned over machines taking |
|over (like Hollywood and science fiction writers have always predicted). Singularity also allows for the idea that machines may solve problems|
|that we find insurmountable today. Recently, transhumanists have been looking mostly at the adverse effects of singularity. Potentially, |
|artificial body parts can become better than the original. Longevity escape velocity predicts that individuals will stay a decade or so ahead |
|of the research needed to continue extending life and the quality of life. The one really good point the article made was that this research |
|should go on because “It’s not about the fact that aging kills people and |
|takes lives. It’s about the fact that aging kills people really horribly” and that is just not acceptable any longer if we can help it. |
Based on the Lab and microscope Activites, answer the following questions:
|Indicate if the following substances are a strong acid, weak acid, strong base, or weak base. |
|Substance |
|Answer |
| |
|Saliva |
|weak base |
| |
|Beer |
|weak acid |
| |
|NH4 |
|weak acid |
| |
|HCl |
|strong acid |
| |
|Lye |
|strong base |
| |
| |
| |
|The standard binocular microscopes used in labs can typically only magnify up to 1000x. Research and discuss two technological advancements |
|for viewing microscopic objects living or inanimate. |
|Answer: In 1931 the electron microscope was invented making it possible to view objects as small as the diameter of an atom. While this does |
|not make the atom visible, it does, in effect, isolate individual important molecules. It “magnifies” things up to one million times. |
|Unfortunately, because of the conditions needed for the electron telescope, living cells cannot survive under their high vacuum. |
|In 1981 the scanning tunneling microscope (STM) was invented which allows atomic-scale images to be seen on the surfaces of metal. It is |
|three-dimensional which allows defects to be seen as well as size and conformation of molecules on the surface. It is of use in industrial |
|research. |
|Identify the following elements according to the atom structure provided. List the name and symbol. |
|Name |
|Symbol |
| |
|Carbon |
|C |
| |
|Oxygen |
|O |
| |
|Silicon |
|Si |
| |
|Neon |
|Ne |
| |
|Aluminum |
|Al |
