An organism stops expressing the traits of a fossil gene because of the lack of use. For example, ice fish, when they were examined, had a remnant of the alpha-hemoglobin was detected and there was no beta-hemoglobin at all. “The remaining chunk of the alpha-hemoglobin gene is a molecular fossil, or pseudo gene, a vestige of red-blooded way of life in ice fish ancestors that was abandoned.” 3. How do ice fish obtain their oxygen? What might happen to ice fish if the waters around the Antarctic became warmer?
The Polar bear has not been on the planet for that long. They evolved into their present state by adapting to the polar environment. In the history of the world, species have flourished and then died out again as their environment changed- which is why we no longer have dinosaurs roaming the earth! If the polar bears are able to adapt to changes in temperature then they will continue to exist as a species, but if not they will die out and something else will take their place. Either way, the natural world will remain
The DNA fragments were then separated after I performed a gel electrophoresis (process used to separate them with gel and an electrical current) When compared, your loved one's DNA did not match the DNA of the bones found. * 4. Suggest reasons why it was helpful to digest each of your samples with two different restriction enzymes? How do the results of your gel reinforce this point? * It gave two different constants to match the unknown DNA to.
Thoreau-Observation Paper Living through a harsh winter in Northwestern Ohio, one may find themselves enveloped in a grey cloud of depression and lethargy. Nature, however, has a gentle way of reminding us that life, and the emotions we experience during it, are on a continuously changing path. Just like the sleeping stillness of winter is eventually replaced with springtime’s bursting buds of colorful new life, so too are the dark times in our life exchanged with those of great hope and joy. By closely monitoring nature’s every changing seasons one can be reminded that like our state of mind and emotion, nothing lasts forever. Watching the frantic flurry of snowflakes falling forlornly onto the cold frozen ground, I wondered if the sun would ever shine again.
The fact that the diamondback is ectothermic or cold blooded, contributes to its diet as this feature means it does not need as much food as warm blooded animals for energy. Another adaptation trait is the diamondback’s behavior during each season. In the winter months it hibernates in underground boroughs, in the summer time, it hides during the day and hunts at night which means it is most active in the spring and fall. The ability to hunt for prey is vital to survival. The diamondback rattlesnake has infrared vision which helps it sense heat from warm-blooded prey as well as sense the danger of other predators.
By looking at the spread sheet it conveyed that all 3 bacterials were negative for the oxidase test. So, I assumed that if the oxidase test performed came back negative as well, this would verify that I chose wisely. The oxidase test would also detect if the bacteria produced cytochrome oxidase, it is also used to segregate between aerobic gram-negative organisms. The last experiment set up on this day was the fluid thioglycollate medium (FTM) so that I could verify if my unknown bacteria was a aerobic or anaerobic
Pavel Tislenok Lab Bio 100 week 8 Frog’s dissection 1. First we gathered all tools for dissecting a frog which was female. 2. All of our crew has worn gloves for protection from the chemical that the frog was in, and for our own protection of cutting ourselves. 3.
However for someone that has moved from a location that never gets snow to a location that gets large amounts, it can be difficult. During the winter roads can be covered in snow and there is the threat of black ice. Accidents can occur any time of the year, hoewever accidents are more prone to occur during the winter months.This is why driving during the winter takes experience and caution. Summer is the easiest time to drive. Like I mentioned earlier, this doesnt mean accidents will not happen during the summer months.
Alaska, especially in the winter months, can be brutally cold. With globalization, Inuit have been able to move out of igloos and into more permanent residences, and are more capable to stay warm. They have also adapted to more modern means of transportation and communication, such as the snowmobile and the internet. Another, great example of changing their cultural identity comes from the video that we watched in the class, where the women’s of Inuit represented their identity through the use of various extraordinary tattoos on their faces. However, they have stopped this
You can also wait until the last second and search for an extension cord and then plug it into your hair dryer so you can defrost your windshield with it. Cold weather can cause you to leave earlier as well because of the possibility of ice on the roads. Hot weather definitely has the advantage concerning having to leave earlier or having to prepare your vehicle to leave, because the only thing you might want to do, although not a necessity, is start your vehicle and crank up the air conditioning. Both types of weather often determine what kind of recreation is possible. For instance, snow man building doesn't quite work out in
