Is Sex Important?

            Before reading Dr. Tatiana's Sex Advice to all Creatures, I knew vaguely about the concepts of asexual and sexual reproduction. I could recount that asexual was with one partner while sexual was with two. Questions flowed through my mind: But why would an organism conduct asexual reproduction? How does that even begin to happen?
            After reading, I discovered asexual reproduction has quite the list of advantages: it's easy, it's fast, no mate or date, and it enables organisms to make a lot of offsping. There's the added bonus of having thousands upon millions of you. Yet there is one costly disadvantage that defeats most asexual species, species are more prone to extinction. Because everyone is like you, your species can not adapt to its enviornment; there are no mutated organisms that will survive. 
             On the flip side, sexual reproduction helps counter his threat. In addition, mutations may become positive and in the long run, positively effect the species. But sexual reproduction has baggage too. Organisms are exposed to STDs and parasites. It requires time and energy. Genetic combinations might result in bad outcomes. 
             Knowing this, I understand sex is important. The survival of most species relies on sexual reproduction. Without it, humans wouldn'tt be what we are today. Overall, sexual reproduction's disadvantages out weighs the plausible outcome of distinction.

Candy Electrophoresis Lab

1. When you analyzed the results of your gel, did any of your experimental samples contain dyes that did not match the four reference dyes? All of the sample dyes corresponded to a reference dye, however, we found that yellow 5 was not found in any of the sample dyes.  2. Look at the structures of the dyes pictured here. Which of these dyes would migrate similarly to the dyes you examined in this lab? Why? I think blue 1, beetroot red, and carminic acid would travel at similar rates because they are similar sizes. Citrus red 2 and fast green FCF would go at similar paces to the rest of the dyes. 3. Many popular dry dog foods and dog treats have FD&C dyes among their ingredients. For example, Beneful dry food contains Yellow 5, Red 40, Yellow 6, and Blue 2, and Snausages Breakfast Bites contain Red 40 lake, Yellow 6 lake, and Yellow 5 lake. (Lake dyes are the insoluble forms of the FD&C dyes.) Why do dog food manufacturers put artificial food colors in dog food?  Dyes are

Bleaching Jeans!

In the jean lab, we set out to answer what concentration of bleach is best to fade the color out of new denim material in 10 minutes without visible damage to the fabric. Our hypothesis was if bleach breaks down pigments, then the denim will lose its color. We found that the 'best' concentration is dependent on what you're looking for and value. The 100% bleach had the most drastic results with an average of 9 in color removal. In the end, the pigment was more yellow than white. The fabric square was stiffer and the ends were frayed. (The ends were frayed because we cut it. Normally, when bleaching jeans, the hem wouldn't get frayed). This led it to have a fabric damage of 1 1/3. I would consider this one the 'best' because though the fabric turned yellow and is most likely not favorable, it took the color out of the denim. From reliable online sources, you can find data that supports our findings. This also proved our hypothesis because the bleach broke down th
