Apr 27	comment	What are the long-term negative effects of going without water/food for a period of time This is the second time this EXACT question has been asked. Complete with bolded sections and all. Like the last time it was asked, you will not get any answers. You are asking for studies that do not exist, and as far as I'm aware there simply aren't any known long-term affects from temporary starvation or dehydration.
Apr 14	comment	Would muscle fatigue still occur if aerobic conditions for a working muscle is maintained? I think you need to clarify something. I was going to answer, but then I realized there's a difference between constantly working and operating under stress. Your heart is an example of a muscle that never quits, so it is one example of an answer to your question. However, if you mean when muscles are stressed beyond their normal operating parameters, as the heart rarely is for extended periods of time, then that's a different answer.
Apr 4	comment	How do axon terminals report to the soma? Have you looked into the role of Oligodendrocytes and other Glial cells? The myelin sheathe is part of another cell, which has intimate contact with the Axon. I wouldn't be surprised if Schwann Cells (etc.) actually provide many of the metabolites and proteins to the Axon and Axon Terminal.
Mar 23	comment	How does paracetamol interfere with immune system? Your first question is a repeat of this one: biology.stackexchange.com/questions/7541/…
Mar 17	comment	Agony, Hydrophobia and viruses in the light of evolutionary principles I'm with Kevin. These seem like separate questions. To give you an idea of the first - Evolution via Natural Selection doesn't really 'care' how you die, as long as you've passed on your genes (reproduced) beforehand.
Mar 14	comment	What part of the cactus photosynthesizes? Since photosynthesis is correlated with chlorophyll, I'm guessing the green part.
Mar 3	comment	Exercise causes number of cell divisions to approach Hayflick limit faster? And hence shorten life expectancy? I don't know about the Hayflick limit in humans, but Olympic-class athletes tend to live longer than average, as long as it wasn't a contact sport: well.blogs.nytimes.com/2012/12/19/live-as-long-as-an-olympian
Feb 22	comment	Can this theory on the evolution of human appearance be flawed? What he's getting at is called homogeneity, for future reference. At least, I think so. 'Completely average looks' means very little in a biological context since evolution works on a genetic scale.
Feb 20	comment	Difference between “transcriptional activity” and “RNA expression” I'm not familiar with what you're doing, but off the top of my head I'd say that the RNA Expression might be referring to everything post-nucleus in that the Introns are missing. The Transcriptase would show more activity because it would still Transcribe both Introns and Exons.
Feb 20	comment	Are there examples of encryption in nature? You may want to define what you're looking for a bit better. Isn't something that appears random, but is actually a complex formation practically the same as encryption? I don't see the difference between your first and second sentences in your second paragraph.
Feb 19	comment	Melting point of a fatty acid? You'll want to wait for a full answer. All of the answers will affect the melting point to some degree, but whether it's a significant amount is another thing.
Feb 19	comment	How can the child and the mother have different blood types? The fetus makes its own erythrocytes from a combination of the father's and mother's genome. If the mother is B and the father is A, the child will be AB as they are co-dominant. Only 'O' is recessive. This may be a too-basic question for this site...
Feb 18	comment	Melting point of a fatty acid? Are you looking for one answer of the 5, or are multiple answers possible? If it's the latter, then it's 1, 4, 5 from a quick recollection.
Feb 18	comment	I'm 20. Can I still grow taller? @rg255 - Sure, there's going to be variance in everything. However, I don't want to mislead, so I use the averages. Answering 'Yes' when you're talking about 10% of the population is misleading to me.
Feb 18	comment	I'm 20. Can I still grow taller? Edited question to better fit Bio.SE guidelines.
Feb 13	comment	Death because of distilled water consumption +1. I'm with Recursivelyironic. Most of the ions in our diet come from the foods we eat, not the water we drink. Unless you're sucking down softened water in the shower, your salt and calcium should be coming from your big dietary sources - fruit, veggies, meat, seasonings, etc.
Feb 12	comment	Is there an “Adam and Eve” for each new trait during (not just human) evolution? @IlyaMelamed - So you're talking about different ways traits evolve. Convergent, divergent, etc. If you can find a way to make that clear in your question, then I'd take away my Duplicate vote since there doesn't seem to be a good question covering evolution of traits.
Feb 12	comment	Is there an “Adam and Eve” for each new trait during (not just human) evolution? I think I'm with Michael Kuhn. The concepts between the questions are very close. Ultimately the answer is 'Yes' - there's an "Adam and Eve" or "Parent" to every extant species today, but it's probably not like you'd expect. They were simply able to pass on their trait more successfully than others.
Feb 12	comment	What is the advantage of circular genomes for bacteria and linear genomes for other organisms? @Bitwise - I'm sure there are examples of linear chromosomes in Bacteria/Archea. I don't think there's an explicit need for it to be condensed, but its ability to be condensed is very useful to the cell. B/A don't sexually reproduce, may not have a nucleus smaller than the cell to stuff all the DNA in, and may not need to shut down large swathes of genes they are forced to keep around (like women do with many genes on X-chromosomes). So I'd say not necessary, but very useful.
Feb 8	comment	What is the advantage of circular genomes for bacteria and linear genomes for other organisms? @Bitwise - Speed is definitely part of it. It takes time to condense all of a linear genome into Chromatin. A circular genome isn't necessarily easier to replicate (the proteins involved operate at about the same speeds if I remember correctly), but when your species depends upon a very, very fast generation time then a genome that you don't have to pack is a huge advantage.
