Have you ever thought that having good hygiene kept you from having bacteria on your body? Well your wrong no matter how clean you are you will always have bacteria on your body and the place where there are millions of bacteria cells are in your mouth. Your mouth is the place where there’s more bacteria than even earth. You can help to keep the spread of bacteria down by making sure that you brush your teeth regularly and coughing into your hands. In my opinion there is nowhere where bacteria is absent we are exposed to bacteria everyday of our life. I also think that when we do testing on other planets like mars that we are transporting our bacteria to that planet. We also do not know if we are bringing any back with us because we know only a little about other planets. So no matter what we do we will always be around bacteria and there’s nothing we can do to get rid of bacteria so we are stuck with it for life.

Clean up, clean up, everybody have your share. My share of the world’s bacteria probably lies in my ears. At least this is my theory. I know there is probably another part of me or my house that is worse, but the ears intrigue, especially when it comes to where they are pierced. I had never thought of this with my first earrings, as I got them when I was just one, and I was a little short of grasping the concept that bacteria grows on everything. Then, however, when a good decade and a half had passed, my cognition of the subject increased as did my interest in holes in my ears, and so I ended up with a bottle of antiseptic and some shiny studs. This bottle of antiseptic, I came to learn, really was necessary to kill the bacteria that (I believe) grows in ear piercings. The reason I think they were so numerous was because missing just one day of cleaning seamed to have had a very bad effect. The dark little nook must still be a common stomping ground as (yeah, this is gross, I know, but it’s Bio, and frankly, Mrs.R’s not a squeemish person) earrings are never perfectly clean when you take them out and change them. I currently don’t really take any extra measures to kill them off, though, as they aren’t really hurting me. Now, on the flip side, the cleanest place I can think of is probably a can of anything. This category would include things such as green beans, soup, and vienna sausages!
Our friend Mr. Pasteur is my logic behind this. Heat and sealing makes it (so far as I know) impossible for it to grow.
Now we reach the subject of sending bacteria to other planets. Is it possible it could happen? Well, anything’s possible if you believe, my friends. So, yeah, I would say us humans are pretty likely to try sending some up on a probe some day.
Also, I think they could definitely survive. That is, if you picked the right friends to take. If the planet doesn’t have oxygen, bring a bug that doesn’t need it. If the planet is hot, take some that can take the heat. Science could probably even manipulate the bacteria and add plasmids in that help them to adapt to whatever environment they are going into.
Thanks for reading my novel, if you got this far!

Alright, i’ m a really nerdy guy and i follow documentaries on cosmology, medicine and the like, so, to start this post off I guess i’ ll share my experience with such things. Last night i was watching into the universe with Stephen Hawking, the specific topic, aliens. That’s right, i sat down for 43 minutes listening to (a thankfully narrated by someone other than Stephen Hawking’s computer voice)a documentary of his thoughts on the topic of extra-terrestrial beings. he believes there is an ocean on Europa and that beings could be living in it at this very second. Most importantly, however, he believes we aren’t alone. Alright, told you about the documentary, now i get to the main point. Life starts with an assortment of chemicals, and energy. Like an archaebacterium, there could be entire populations consisting of animals created from gases, or maybe even silicone, and drinking liquid nitrogen, basically, beings that live in extremes of nature and still living. Bacteria to me would be most plentiful in the school that i attend, one student can carry 10 to the 40th bacterium on his or her person at any given time, well, with 10 t0 the third students at our school the number of bacteria reproducing could easily reach 10 to the…doing math here… 10 to the 40,0ooth, which is a large amount and it’s a wonder we don’t get sick at more frequently, especially when the guys walk out of restrooms without washed hands. I personally wash my hands whenever i’ m within 5 feet of a sink, not to be germophobic, just because i enjoy being healthy( and the bathroom conundrum is scary, to say the least) I honestly believe that there is no place where bacterium can’t be found. Scratch that, i believe no bacteria are present the ingeredients for life haven’t been mixed yet, just adding that. Sure, we’ve sampled Mars’s surface, may have turned up blank there, but how deep did we go? There is one problem life always faces: survival. Can we send bacteria to other worlds? I think it’s possible, yes. Can we set up bacterial colonies on Mars? If it suits us to do so, that would be affirmative. But can Those bacterial colonies survive on a foreign world? I think not! Now, hold yer horses thar mistah, i ‘aven’t told ya why yet. Though the forces of evolution are great and animals can do such things very quickly, i think in order to evolve you need to live. Say the bacteria we send are photoautotrophic, that’s dandy and all, they have Carbon dioxide to make energy with, but wait, we put them on the wrong side of the world and they won’t reach sunlight for another 21 days, do you expect them to live so long? because I don’t. Goodbye 2 years of work. So, not only do we have to make sure that the bacteria have something similar to adapt to, but we also have to take into account where we place the organisms and if they’re hardy(Weinberg) enough to survive for an extended period of time. Thank you, that’s all, feel free to comment or throw some nerdy humour at me if you wish, but before i go, an unrelated question. what does E=MC Hammer equate to?

I believe the kitchen sink is the space where bacteria is most plentiful. There is more bacteria there than on a toilet because many food substances come in contact with the sink on its way to the disposal. This means multiple bacteria. We use Dawn Dish Soap and Kleen King stainless steel cleaner to clean the sink and help control the spread of bacteria.
Sanitized surgical instruments are about the only place I can think of where bacteria is completly absent.
Yes, I believe humans can send bacteria to other planets. Space probes may carry micro-organisms to Mars, but I’m not entirely sure. If there is some form of life on Mars, then I believe that bacteria could survive. It could also mutate into a new form of the original bacteria. But it there is no life form on Mars, then the bacteria would most likely die.

When you hear the word evolution, you probably do not think of cars. Cars may not be actual living beings, but they have evolved along with the human brain. A car can not evolve on its own because it is dependent on the human brain. As we humans evolve with the latest technology, we are able to improve our car’s ability to be more effective. So technically, cars can not evolve by themselves, they need a human to progress or evolve.
In the Transformers series, there are cars called Autobots, (and Decepticons but I will stick to the Autobots because they are part of the good side) which can transform from car to robot. This movie displays the perfect evolution of cars if it was actually possible. The Autobots can speak, run, fight, drive, and so much more. If only this could really happen….

Yeah, its called the Big Bang, I know. But this rhymed. And despite the fact that the big bang is highly controversial and not proven in the least, it’s little brother, micro-evolution, is much less controversial and proven in the most. We see it regularly, in plants with pesticides, and less related to biology, with cars. It is clear that cars have adapted from what they used to be by thinking out of the box, or rather out of the house, at least, and into the driveway immediately outside of my humble abode. Here sits the 1994 Oldsmobile. That’s right, a car that is as old as me. A car that looks like three cardboard boxes put together and painted an ugly maroon. When I gaze not-so-lovingly at this car, not only do I not wonder AT ALL how it got rejected in the process of natural selection, I wonder how the gene pool didn’t kill it off after they figured out what a hideous and malfunctioning (windows don’t work, handles fell off, seat belt broken, seat held up with wooden box) being it would end up being. In fact, with the passionate urges I have to go at it with an ax, it’s a wonder how it has survived in my driveway for so long. Yes, and I will help it die off as when I purchase a car, I vow that is will have nothing in common with the ugly thing that resides so close to me. It will be the something that is at least an 8 on the scale of 1-10 beauty in cars, and I will be painting it bright metallic magenta. Automobiles are a prime example of evolution and the little changes things go through, because it is not only survival of the fittest, but also of the prettiest. In the wild, don’t the hottest dudes get the girls? Yep, its the same with cars. Who hates the car? The three women in the family. Who likes it? The man. Hem…

Driving a VW Passat every day, is hard for me to imagine the lifestyle attributed with the early automobiles. It is fascinating to see how quickly our society has progressed from the horse and buggy days to environmentally friendly vehicles averaging twenty plus miles per gallon. However, looking at the progression from a biological view, the evolution of the automobile becomes clearer and coincides with the Darwinian Theory of Evolution. In a sense, the automobile industry undergoes natural selection through the way the community buys into different models or versions. For example, much like the giraffes with longer necks survived because they could reach the higher trees while those with the shorter necks were unable to and died off, certain models survive only a short time in the industry if they do not the consumers’ expectations in safety, efficiency, and performance. Therefore, it is similar to the “survival of the fittest” while the best vehicles survive, and the others must evolve in order to meet the expectations they failed to.

Yes, I did look up that fictional character’s name to ensure clarity and yes, I will be speaking about cars today. Though I have a very meager interest in the subject, the discussion question demands that I expound upon it. I’m sure that if you are as nerdy as I am and stay up on hazy Sunday evenings to watch the show Curiosity, you have seen the newest Nissan commercial and their aspiration to become the most ecologically friendly car company on the face of the United States. The reason I point out this specific commercial? Because! it shows in that very commercial, how the evolution of cars is changing. Cars are no longer “out of touch” with the environment, they have become adapted to suit it. Just like the Galapagos Finch in Darwin’s studies, cars have adapted to conserve more fuel and tap into the environment with less harm. On a side note, Nissan’s exclusive cargo ship, The city of St. Petersburg , has also changed to conserve fuel while still carrying mass shipments across the ocean like a modern day viking barge.The designs for cars have become more suitable (and might I add, handsomely made of clay) to take charge of the winds and not become slowed by it’s battering. Solar panels have also been a recent discovery in car manufacturing, to steal the sun’s might and produce clean energy. Not quite sure to end this most might of monologues, So I won’t! I will instead leave you with a topic to think about and perhaps comment upon. Are you ready?! Non-Newtonian Fluid. Good for swimming or bad for the lungs? Please comment on what you think!

As everyone knows, the first mass produced consumer vehicle was the Ford Model T which, by the way, Jay Leno drives around sometimes. The Model T was created by using the perfected assembly line. Of course, this was at the time where drag racing didn’t exist, and the car probably topped out at about 30-40 MPH. However, like everything else, the creation of automobiles has evolved since then.
Being the owner of a 1948 Plymouth Deluxe, I realize that engines and transmissions were not the same back then as they are now. Now, there are cars that can get upwards of 30 MPG with a big V8 engine and 7-speed transmissions. The drive train in my Plymouth is a 60’s vintage 350 cubic inch V8 with a 2-speed transmission that can’t get more than maybe 14 MPG and has pull cable of the choke.
While the only thing about the assembly line that has changed has been that humans have been replaced with machines, new technology has advanced the parts that go into a car. From the 30’s up to about the 70’s, cars were made out solid steel, while today’s cars are made from different pieces of fiberglass body parts. My Plymouth weighs over 2 tons with an engine, while modern coups weight less that one ton. Anyway, 60’s vintage drive trains have evolved from bigV8’s to even bigger V12’s. Granted, the V12’s can still only get about 14 MPG, but it’s still an improvement.
I have a drag racing game on my Samsung Galaxy S Stratosphere smart phone that features the top sports cars from the world. Some of the fastest cars on the game include the Novitec Rosso, which is a Ferrari, the Pagani Zonda, and the Bugatti Veyron, which each top out at about 250 MPH stock. These are the cars that all have giant V12’s that sound like jet engines when they startup. So basically, cars have evolved from extremely slow puttering buggies to extremely fast and extremely loud sports cars that cost upwards of $1 million.

Science and evolution as a process allow advances in technology and organisms to take place; n important factor in growth. Specifically, automobiles have evolved tremendously in a short period of time. This is possible because of evolution, in a light sense, in the way that as the best possible systems and methods of production are discovered, the lesser blueprints are discarded and forgotten. Progression becomes a bidding race to find the absolute perfect combination of systems,(highest mileage, lowest break-down rates, etc), which results in a Darwinian method to cut out the weak, and emphasize the strong.
Design is effected by the population as the demand grows for a certain style. The output from manufactures increase as buyers determine what they fancy, thus spouting a chain reaction of evolution. The previous sought after design becomes a thing of a past, seen more commonly in used car lots, while the new brand is showcased on pedestals in competitive districts. This compares to the mating processes of some mammals, as the most attractive traits, (long tails of some species of birds, largest wolf in the pack) receive the most attention, spiking the reproductive success rate.
