  1. I think its a tie between the amount of debt in general, America's debt, college debt, credit card debt, or the other problem, the distribution of wealth, the wealthier people getting even more wealthier, i guess this covers debt then so maybe thats the main problem.
  2. I do not understand how can somebody be born a girl but not want to be this gender. Don't you develop estrogen in your body when your forming into a girl and it forms the brain and how it thinks. There is very few differences in the male and female brains " Many neuroscientists had already concluded that brains are checkered with a mix of male- and femalelike structures, said Jordan-Young" , the study says only 6 percent of the brain is distinctively male or female. but even with little differences in the brains there are very much differences with the hormones that are released you are still
  3. has it been proven by science that there is only one person that it perfect for someone, the rest may be good but not as good?or is the opposite really true? i always belied that thats what my parents taught me, but many other people I talk to have a different opinion. they think that there are many people that work equally well with someone.
  4. "There are few pathogenic organisms that can cross the passive barriers themselves - usually they must be breached. A cut, tear or some other means to gain access to the "inside". We don't really need the "good" germs in this sense as our barriers are quite effective. But they are not inviolable; we are all subject to things that can damage those barriers." i see so our bodies have barriers that keep pathogens from entering but if the barriers are broken good germs can help and the good germs can adapt and thats their advantage. you are very knolagble on this topic, fantastic answer. thank yo
  5. i found some things that it could stain , im not sure if this si what oyu are looking for but.. it can stain " mammalian cells in monolayer culture, stains are supposed to mark cells that have lost membrane integrity,Erythrosin B and FDA are used as fluorescent dyes, whereas trypan blue colors via light absorption. The effectiveness of both vital exclusion stains is assayed by their ability to stain a high percentage of monolayer cells exposed to treatments lethal to an entire cell population." source: http://www.ncbi.nlm.nih.gov/pubmed/6090533 it is also subject to photodegradation, which is
  6. I think that carpet bombing the poor is very unethical yes there will be more space but many times the poor are the moral ones because they have learned empathy. taking the wealth from the rich is difficult and dangerous, they usually have guns and protection. I would love a world for of rich and happy people but i do not think that is possible, there will always be a need foe factory workers which are usually low wage unless its in japan, there will still be disease, there will be less incentive to work for many people if everyone was independently wealthy, I know that money and status are
  7. I don't know whether to post this in biology or anatomy.I dont know how to move it if it dosent belong here. It is also kind of a why did we evolve this way question. Why do we need good germs for protection from bad germs? I get it if its for digestion. dont we come equiped for enough cells phagocyte cells that kills all the germs and even viruses that attack us? I learned in anatomy and physiology class that.There are already equipped with blood cells like neutrophils and macro phages they are phagocytes that squeeze out of veins. they release chemical signals to tell endothelial cell
  8. thankyou I also read an interesting article I don't think its vivisection, but japans scientists created a light sheet fluorescence microscopy in order to create tissue nearly opaque. it allows "examine the mouse’s organs without cutting into them" here is the article http://www.nydailynews.com/life-style/japanese-scientists-turn-mouse-invisible-article-1.2004756its really interesting to me and exiting we might discover how to turn people invisible. relating this back to ethics it might also really be bad. people can more easily spy on other countries and might find something out that causes
  9. i do not think there is a name for that, i know there is a name for an area next to that the bridge of the nose, but that area is not specific to a muscle or bone and is not esily isolated meaning its hard to pinpoint the boarders of where the area ends.
  10. yea you might be right if they are staged. immatfaal good to hear that the ethics is looked at in science "Or very very old. Some of the child psych experiments of the 50s and early 60s would - quite literally - get you locked up if you tried them now. The general view is that many experiments carried out in the past were immoral and unethical - that's why we have ethical research committees which prevet (prevent?) experiments nowadays. But that said - most experimenters were not the "mad scientist" then, and they are not now; the MERCs unfortunately make life massively more difficult fo
  11. i read an article actually, many articles on science experiments that harm people that catch people off guard and plays with their emotion, even if you get consent to create the experiment the people dont really know what they are consenting to. One guy pretends to be homeless to see how much money he can get for science. this is giving false pretenses is'nt this against the law or is it protected. There is a different experiment that a person pretends to get a heart attack to see how many people will react and help him., i do think its wrong to test things on animals but it is justified beca
  12. i don't understand why people post mean things online, I could speculate its ignorance and unintelligence but I think hopefully not that many people are that stupid and insensitive in person.I think people are either trying to get attention or they are trying to get their frustration out because nobody will know who they are in life. i tend to ignore anything mean online, its much harder to ignore when its said in your face. i dont say anything mean online.I never want to hurt anyones feelings even if its virtual.
  13. this is a hard question to answer because not a lot of good research has been made its hard to test love and to measure it its so different for e everybody. I think reaserch shows that we have similar reaactions to animals and we are considered animals so i would think we are a more emotional and social animals.
  14. every one has different ways of learning, some people memorize better if they listen so they watch lectures when they are at home.
  15. if there is internal respiration then there has to be external respiration because you have to take in oxygen from the out side. , is this something you find fascinating or extraordinary? there must be a reason why you post this.
  16. these are good questions" Is the emphasis on standarized testing appropriate to gauge a student's skill level? no i think they dont nessiserly test you on what you have learned, they sometimes put alot of extraneous information. espesially the SAT's i took the twice ce studied hard and still didnt get a decent enough score to get into the college i wanted. why is there a high turnover rate in teaching positions? because there is many teachers. If given the financial opportunity, what would be the best way to go about teaching a student? I think good teachers cause you to think about a sub
  17. I agree with jhon cutber. military violates our freedoms. Although i can see what michael123456 means by saying that military service helps unemployment but still if everyone had the government put them in a set job after college then there will be less unemployment too and less people will die. I would try to stay away from making anyhting mandatory if it is not nessisery.
  18. in many other countries (not the USA) they have mandatory military service policy. my birth country they require military service and a friend of mine and I were talking about that and he thinks that the us should require military service for all men and women, he thought that it will teach people discipline and make people better workers. It really hit home for me and made me really upset, I told him how would you feel if your family member died in a war, and he said he will feel proud because he defended our freedoms. I think that sometimes well most of the time war is not really defending s
  19. i had the same questing I want to become a scientist too but I am getting an art degree. I think you wont be able to be a pure scientist, studying things coming up with experiments, you might however become researcher, assist looking for data and testing experiments.
  20. this is very interesting. but can it find out the material make up of anything useing this light? how accurate is it? i think if its so small and cheap it wouldn't be as accurate as non commercial lab spectrometers. I have never used one, but i have used a gigercounter/meter for testing radiation.
  21. maybe he could find used ones then or out of print textbooks. Textbooks for colleges are really expensive but I wasnt sure if others, like highschool or general textbooks were expensive, I found a couple free textbooks on anatomy and physiology online for free without any unsafe or illegal torrent downloads.
  22. thankyou for your responses I dont have any personal experience with unschooling but I do have personal experience with this kid. and I have experience with some other kids that were home schooled, one did end up going to college to an art school and the other just started working right away, she did want to go to college though. I just know how my family raises children and shes very leniently, for her fifth birthday she decided to throw her daughter five birthday parties,she lets her eat as much sweets as she wants to ,and basically she eats nothing but sweets I can understand someones reaso
  23. Why do muscles need multiple heads? and are all the heads in some muscles attached all on the same bone, as far as I remember the triceps attaches at least in two different places at the superior end. into the coracoid process and the clavicle.but i wonder other muscules like one of the facial muscles that is a bipennate muscle probably has to attachments would it cause something to move in two different directions depending on which tendon it pulls on?
  24. I feel so lucky that I get to go to college and afford textbooks eventhoungh I do not like my college. hopefully you will get to move out of Malaysia to somewhere where textbooks arnt that expensive. I always get really exited thinking about college because to me its not just an education, its opportunities and freedom, to meet people make friends, get close emotionally with people and make work connections, along with have a good time.(sorry if i misspell something, I try to do my best on this site)
