  1. The movie was called "Julie and Jack", and I randomly selected it from the (legal) movie downloader program that I subscribed to at the time, knowing nothing about the film. I'm fairly certain that the version I saw was pirated. At least I hope so. The alternative is that this was the lowest budget movie of all time, shot on a cell phone's camera: image was grainy and slightly wobbly, lighting was terrible, color was flat, and sound quality equally bad, echo-ing throughout the entire thing. The storyline and dialogue were gleefully thin and based on stereotypes of people, as if the w
  2. We don't really need evolution for group formation, per se. Chance alone is sufficient to explain aggregation. Keep in mind, individual drops of oil will aggregate spontaneously into a micelle if they happen to bump into each other, and they have no brain, or capacity to evolve at all. Additionally, groups may form for external reasons where the individual members don't really benefit at all, and would "prefer", if given a choice, not to be in a group at all. A single tree in a forest is an example of this. (Please keep in mind, I'm not a plant biologist.) The forest has sprung up due
  3. motile = able to move on their own, through flagella or similar non-motile = unable to move on their own The "Kingdom Monera" comment is throwing me off. Are you saying that you're in a class that's *currently* using the 5 Kingdom system? Biology's been taught with the three domain system for at least fifteen or twenty years...
  4. You're at a point where you'll need to select one or the other, if you want to continue on immediately after graduation. No, you may not practice either of these with a BS in anything, including nursing. These are both specific advanced degrees, and very, very competitive programs. My understanding is that NPs are easier to place than PAs; they have equivalent amounts of schooling, as both are standard Master's degrees. The applicable fields are specific, but NP's may work independently as generalists, whereas PA's will always be affiliated with a physician.
  5. So there are a lot of studies out on the benefits of coffee or tea, including lower incidence of a number of cancers, but few long-term studies on caffeine specifically. The reality is that most people don't go through life popping caffeine pills throughout the day, so we can't easily tease apart the effects of caffeine from the products that have it, and both coffee and tea are known to have other bioactive compounds. And it's a tough one to get info about the short term effects of coffee and tea for the opposite reason, as many of the studies looking at coffee's effect on the brain are act
  6. You'll likely end up with a "clumsy plate" (you meant mixed colonies, right?) regardless of sampling technique, because bacteria are ubiquitous. But, to some extent, they should be resolving into individual colonies, which, with good technique, can be sampled to see which one you want to streak into a pure colony. Additionally, using your shoe isn't going to guarantee an endospore-forming colony, or is it going to rule out yeast. You'll have to conduct a number of tests to determine the characteristics each colony does or doesn't have. Rapid staining and microscopy with a light scope ought
  7. 5' 5 & 1/2". Tall enough for me. Hope your experience isn't too painful!
  8. Totally agree with GIMP. I love it for all arts applications.
  9. This is confusing. If the bacteria needs to be novel, you're going to need years to get it to grow in culture, and you'll be lucky to accomplish it, even then. Are you just doing this to learn staining/basic techniques? What kind of media are you using? Where are you planning on keeping your culture? It sounds like you're looking for really basic advice, so I'll gear this towards that. If you can't keep it in an incubator, I'll assume it needs to be room temp. Swab the bottom of your shoe with a sterile q-tip, and rub it all over a petri dish of TSA. If you want to take an airborne b
  10. Not really. There isn't a clear winner yet, and I doubt there will be, given that, first and foremost, you need to keep in mind that neurons are cells, and will require all the standard equipment that cells have. Their production, therefore, requires most of the genome. Additionally, the brain is affected by almost all of the endocrine system, and those components are all over the body, and aren't directly connected to the CNS or PNS in any way. It's a tough thing to separate out. The genes that are unique to neurons are all over the genome, also. The best you can talk about is with
  11. Not feasible as you're stating it. Right now, bacteria have been modified to produce a ton of useful enzymes, and some pharmaceutical compounds. And trans-species and even trans-"kingdom" knock-ins are certainly done, but what you're suggesting has some problems. First, and most importantly, there isn't a single gene or set of genes (like an operon) for "skin". They're cells...human tissue...and a huge portion of the genome is used to build and maintain cells. In other words, practically the entire coding portion of the human genome would need to be knocked into the plant, to make this id
  12. One point to add, the capillaries only contain endothelial cells, and, in fact, are only one cell thick. This maximizes nutrient and waste exchange, and allows for diapedesis, when needed.
  13. Ah, you are correct. My mistake. Slightly sloppy wording in my classes, I suppose. We never had need to go farther with this topic than to say that there were nodes at the nucleus were electrons would never be found, and I never thought of it again.
  14. If you complete your plan of doing those sciences this year, you'll be well equipped to begin the program. I've known two people to enter PhDs in neuroscience with a BA, neither of whom had taken any science courses at all. The program made an arrangement for them to take "basics of gen. chemistry and organic" classes at the local community college; upon successful completion, they were allowed to enter the program. Just to let you know, one failed abysmally, and the other made it through without problem, but neither appeared to have any concept of how science proceeds. You, on the othe
  15. Have you ever done a Punnett square? Having one copy of a dominant gene and one recessive, in a system like you're describing, would be sufficient to show the dominant trait. All this is saying is that your parents would both need to have one dominant and one recessive allele for both of them to have wet ear wax, while their child has dry. It's the same way that two brown-eyed parents can have a blue-eyed child, or two healthy parents can have a child with cystic fibrosis. This doesn't weigh in on the possibility of having Asian ancestry, as it doesn't need to. As long as the percent o
