Re: GSC101 GDB 1 Solution and Discussion Is it Possible that autopsy organisms may produce organic material from inorganic substance? If Yes, write the name of Process If No, write it with solid reason. Answer: Yes, it’s possible because it’s also defined as: Autopsy are organisms which will produce their own food, using materials from inorganic sources. The word “autopsy” comes from the basis words “auto” for “self” and “troph” for “food.” An autopsy is an organism that feeds itself, without the help of the other organisms. autopsy are extremely important because without them, no other sorts of life can exists. the primary life forms on Earth would have had to be autopsy. Process of autopsy: Process of autopsy include photo autopsy’s, and chemo autopsy’s. Photo autopsy: Photo autopsy are organisms who get the energy to form organic materials from sunlight. Photo autopsy include all plants, green alga’s, and bacteria which perform photosynthesis. Chemo autopsy’s: Chemo autopsy’s are organisms that obtain energy from inorganic chemical processes. Today, chemo autopsy’s are most ordinarily found in trouble environments which receive no sunlight. Many got to live around deep sea volcanic vents, which produce enough heat to permit metabolism to occur at a high rate.

Dear Students, Graded discussion (GDB) for the course GSC101 will be launched on 19th August, 2019 and it will remain open for two days. You can post your comments on the below mentioned topic till 20th August, 2019. No comment about the Discussion topic should be posted on the regular Moderated Discussion Board (MDB) which is created for each lecture. The topic for the discussion is: Justify the following statement, “Do you think that is there any positive role of eyes & nose in digestive system of human? Either yes or no explain with solid reason.” Also you should remember that this Discussion is graded and maximum marks for this Graded Discussion Board 5% and it will count in your final Grade. So these marks may be helpful for you to get A grade from B and B grade from C and so on. In the end you should also know that we will not extend the date of discussion in any case. · Plagiarism is prohibited that is why you are advised to avoid copy/paste from internet etc, if found at any stage will be graded as zero marks. · All students are directed to use the font face Time new Roman and Font size 12. · Don’t use colorful back grounds in your solution. · Use Math Type or Equation Editor etc for mathematical symbols. · It also suggests you to keep your GDB solution safe from others. No excuse will be accepted by anyone if found to be copying or letting others copy.
