Chromatography Experiment of the Drosophila Eye Pigmentation Pathway Introduction: How can the use of chromatography help explain single gene mutations of the drosophila melanogaster bio-synthetic pigment pathway? This experiment was meant to help connect the mode of inheritance with different eye color mutations and pinpoint where they occur in the pigment pathway. The drosophila eye color is a result of two bio-synthetic eye color pathways‚ this is expressed as a trait or phenotype‚ a multigene

mesophyll‚ a higher specific leaf area‚ and improved light capture…" (Matos et al.‚ 2009). The sun leaves were described as "generally thicker with an enhanced quantity of palisade mesophyll" (Matos et al.‚ 2009). Our objective was the presence of phenotypic plasticity in avocado trees based on the differences in the morphology of shade and sun leaves. In our study‚ we asked whether there is a difference in surface area‚ length-to-width ratio‚ mass‚ specific leaf mass‚ and color between shade

Nissan Leaf Every time you coast or apply the brakes in the Nissan LEAF® the electric motor acts as an electric generator‚ converting energy that would otherwise be wasted into battery energy. So even when you’re slowing down‚ you’re charging up. The Nissan LEAF® gets the equivalent of 130 miles per gallon. That’s right‚ 130 miles per gallon. [*] How does it achieve these remarkable numbers? With a 100% electric drive system powered by an advanced rechargeable lithium-ion battery‚ and nine range-maximizing

When people hear candy chromatography‚ they don’t know what to think about it. They of course know that it had something to do with candy. But just don’t know what. Candy chromatography is fun and simple. Candy Chromatography is a fun project‚ plus it has to do with candy. Candy Chromatography is an experiment to find out the true colors of the dyes in candy. When you put a skittle or an M&M in your hand in hot weather‚ the candy tends to bleed the color. And sometimes it shows more than one color

What is chromatography- Chromatography is the separation of mixture by passing it in solution or suspension or as vapor. It’s a technique for separating mixtures into the components this needs to happen in order to do the 4 things analyze‚identify‚purify‚quantify. Many scientist use this to do the 4 steps. When analyzing its used to examine the mixture and to find out the relation with one another. In purifying you need to seperate or take away and put it by itself for further study. In identifying
