  • Which camera do you think is best?

    I'm still looking at reviews for these three cameras:

    -Canon PowerShot SX30 IS

    -Kodak EasyShareZ990

    -Fujifilm FinePix S4000

    I'm looking for a fast shutter, shutter speed. Basically a camera that will allow me to take pictures simultaneously. For example, taking one picture after another. Or, taking pictures of people doing some sort of fast movement, such as a soccer game or a football game.

    Of course the camera has to have a good zoom and MP. My price range is from $0-$379.99.

  • Who is that girl to the Ron Weasley's right in Goblet of Fire?

    I have gone to IMDb already, but I could not recognize who it was or which character she plays. She's in the scene where Ron had asked Fleur to the Yule Ball and they're carrying Ron in to the Gryffindor Common Room. She also shows up in the Third Task after Cedric Diggory dies but comes back to Hogwarts. Any ideas?

  • Help with a Sony Vaio laptop CD/DVD Drive?

    I have a VGN-NW235F model of the Sony Vaio and have had it for about 3 years. After weeks of not having to use my CD/DVD drive, I use it today and it decides not to be recognized. It opens fine, but it cannot read any DVD movies or blank discs. I have looked at my Device Manager and it is said that my CD/DVD Drive is "Code 52," meaning my CD/DVD Drive isn't working properly. I already have tried uninstalling it and installing it, it was a failure. When I put any disc in, I'm sure there's a light next to the ejection button, and it won't come on. Neither will the COMPUTER function (My Computer) recognize the blank disc or movie DVD. Not even iTunes recognizes the blank DVD. All of my notifications have been set to where they are already.

  • From Pirates of the Caribbean: On Stranger Tides?

    (Spoiler Alert) What happened to Philip and Syrena towards the end of the film? I remember him getting wounded from the side and they were talking to each other, they kissed and she took him into the water. Now, since they were so "different," what happened to them? And yes, I did watch past the end credits, and it does not involve him. It was a good movie too; gotta love midnight showings.

  • Help on Newton's Law of Cooling?

    Ok so a cadaver was found in a room, and I'm trying to find out what time he was murdered, the temp of the room, and "k" constant. At 1:30 AM the body temp was 32 C, 2:30 AM temp 30 C, and 3:30 AM temp 28.25. Normal body temp is 37 C. So there's 3 unknowns. I've tried so many ways and failed, I even looked online and they all have the room temp known already so that doesn't help.

  • How do you feel in dreams?

    When you are dreaming, how is it possible to touch, smell, or even taste something you have never felt before? How does the mind think it feels like? Then, if we are touching or smelling something in our dreams, in our sleep of course, what are we touching in real life? For example, the feeling of brick walls; when everything else around you (in real life) are bed sheets, pillows,....and well, your normal bedroom sort of deal without the bricks.

  • Can someone please help me in Biology?

    I have some answers for this, but I just want to double check.

    1. Explain how alleles at loci occurring on the same chromosome can appear independently, as though they were not on the same chromosome. Be sure to identify the cell division processes that give rise to this observation.

    2. Alternatively, alleles at 2 distinct loci might appear to be "linked," meaning that they are inherited together at a higher frequency than would be expected from independent assortment. What does this tell us about the relative position of the alleles on the chromosome?

    3. The phenotype of an organism can be simply defined as its "outward appearance," while the genotype of an organism is its genetic makeup. The features that can be included as part of the phenotype will depend upon what we are capable of seeing or measuring. In an era in which we can "see" the DNA sequence of an individual, one could say "the genotype is a phenotype." Clarify the meaning of this statement, restating it in your own words, and with more detail.

    4. What happens to the concepts of "dominance" and "recessiveness" when we can read the DNA sequences of both loci in an individual who is heterozygous for a particular gene -which term (dominance, co-dominance, incomplete dominance) is most applicable in describing this "genetic phenotype?" Explain your reasoning.

    5. Examine the digestion pattern of a bacterial plasmid. Often molecular methods similar to these are used to identify organisms, or to determine how closely two individuals might be related. Given that the restriction endonucleases recognized and cut at specific DNA sequences, explain how the resulting cutting pattern, as observed on the DNA gel, is both a genotype and a phenotype. How could a single nucleotide change on the plasmid alter the fragment pattern observed in the gel?

    6. Examine the accumulation of a gene product (an enzyme) by measuring its activity (note, not measuring the enzyme protein directly). If we assume that measured activity is proportional to the amount of the enzyme protein present, what does this tell us about the time scale within which a stimulus triggering gene expression can be turned into a finished, functional gene product?

  • What is the role of light energy in this system, and why does it make a difference in the reduction of the dye?

    Oxidized (blue) DPIP becomes colorless when it is reduced -that is, when it receives electrons. A diagram of the photosynthetic light reaction shows that water molecules are the source of these electrons. How is it that the DPIP was only able to receive reducing electrons from the photosystems (and ultimately from the water) when the lights were on, but not when the lights were off. Since the cuvette is mostly full of water, it is not the case that water is the limiting factor.

    So, is the answer something like if there is no light, there is no photosynthesis?
