Question

Question 1- On low-power, you can see three markings of a millimeter ruler in the field of view.

What is the diameter of the field of view when you use the high-dry objective lens?

Question 2- You get home from Wal-Mart with a new MP3 player, but it doesn't seem to be working. Provide three separate hypotheses for why this might be so, and describe how you would test each one, including a positive and negative control for each test.

Question 3- Nursery rhymes are propagated from parent to child over many generations (thus keeping otherwise obsolete words such as "tuffet" and "chamber" in use), sometimes with associated actions, songs, and movements. How many of the properties of living organsims does a nursery rhyme share? In what ways is it similar to living systems, especially living systems that are pathogenic; Staphylococcus aureus for example? Can you think of an equivalent to the obsolete word concept that we see in What properties do nursery rhymes not have, and in what ways are they dissimñar to living systems?

Explanation / Answer

1. ratio of low power to high power objective lens= 10/40=1/4

So at high power you will see 1/4 of the low power field of view (3 mm). 1/4 x 3 = 0.75
in micrometers = 750 micrometers will be the diameter.

2. first hypothesis- battery could be discharged

we will provide new battery in the mp3 player.

positive control: we will test the battery in any equipment working perfectly.

negative control: we will test the old battery in other equipment

Second hypothesis: File may be corrupted

it may be possible that our file is corrupted, and new mp3 player is not able to play it.

positive control: playing the different file in mp3 player.

negative control- playing this file into different player.

Third hypothesis- there could be some hardware damage

this could be checked by keen observation and investigation of mp3 player. or by replacing it with other.

positive ontrol: There is some broken part bon mp3 player.

Negative control: other mp3 player having same breakage still working.

3.These properties are called meme- A meme, as defined within memetic theory, comprises a theoretical unit of cultural information, the building block of cultural evolution or diffusion that propagates from one mind to anotheranalogously to the way in which a gene propagates from one organism to another as a unit of genetic information and of biological evolution.

Living system and nursery rhymes share following properties:

Adaptation to the environment with long term effect.

like cultures propogated from one type of parent to their offspring, like them living organism also inherit some oeculiar characters from their origin and pass on to their next generation.

COMPARISION WITH Staphylococcus aureus: In pathogenic system, If we continuously provide the same kind of drugs for a prolonged period, This pathogen becomes resistant to that drug just like child got habitul to rhyme.

secondly the pathogens adapt themselves to an environment which was once deleterious to them, but now it becomes mimetic and the pathogen obsolete this effect just like rhymes.

Difference: As in case of living organism, there is transfer of genetic material which leads to the development of drug resistant offspring, WHILE in case of meme or rhyme4s, there is no such report or evidence of involvement of storage and transmission of genes.
