What Has AP Bio Taught Me??

So, today is my last day in AP Bio, wow, so thanks Landry for keeping this class going for the few of us that started first semester and stuck it out. I think personally, that having less people in a class is more advantageable. The cliche holds true though, I learned ALOT this year, but not just like the normal content absorbtion, like I actually looked forward to going to class and learning about things like evolution and genetics. Things were never really boring in class, because the discussions usally involved everyone and it was interesting to listen to if you were confused on anything because things usually cleared themselves up.

This class taught good study habits, by having to somewhat teach yourself before lessons from video notes, and filling out extra credit guides, you were taught to be self sufficient and be in control of your own grades. There weren't many projects, but you got to work with different people for most labs and it taught you to work with other people and avoid biased information gathering from the expreiment.

Overall, this class was totally worth the time, credits and AP test money. Good job Landry.

A Day in the Life of a Vacuole.

Looking for a modern day cell storage warrior like Barry and Brandi? Well look no further friend!

Vacuole here, and I may not be on the hunt for wonderful antiques and valuables in abandoned lockers, but I can be found bound inside of plant and animal cells. My membrane (or Tonoplast) can hold water, and other organic molecules and waste, I can typically store these materials until I am enlarged to capacity, when I get full, I either transport and release my contents or keep to myself until needed. My size can not really be pinpointed because I am typically more square in plants, where my talents to create the needed turgor pressure against cell walls when completely filled are used, and similarly in my more round state of an animal cell such as a capillary.

But storage is not all that my job entails! I am a type of guardian for the cell. When I spot a shady material threatening my home, my natural acidic pH value allows me to isolate this material and do away with it. But don't let the pH deter you from seeing my nurturing side, I am the reason that leaves and flowers can be supported on my host plant. The turgor from my plumpness gives the central vacuole just enough pressure to allow the extensions off the stem of the flower to take place.

 

Sometimes, I falter and don't always carry out tasks the way I am supposed to. Some diseases that can be associated with my malfunctions are Battens disease and Parakeratosis. Battens usually makes an appearance in early childhood and it becomes fatal by their mid teens, its symptoms are; loss of sight, dementia, personality changes, slow learning, and seizures before finally claiming its victim. Battens is a recessive inherited trait and simple tests such as urine or blood tests can find if the offspring will have it or not. This disease is associated with me because in the process, the pH of my contents is altered and the transport of materials are defective. Parakeratosis is typically found more in canines, and this disease causes the victim to posses scaly skin from dryness, and their hair follicles are typically damaged and blocked from resurfacing.

  

I think that I am dubbed a Cell Warrior because I am responsible for most of the protein and molecule waste/water/food. The cells health depends on my ability to capture the illness and dispose of it before the whole system falls into chaos and pH balances fall out of whack. 

     

Wait, So Humans Aren't Perfect??

We humans love to travel, but we always find the need to bring back souvenirs! No, Not necessarily "I ❤ NY" t-shirts; more like... Snakes, Bugs, Fish and other related animals.These animals are called Non-Native Invasive Species and they are a species living outside its native distributional range, which has arrived deliberately or accidentally by human activity. 

Now, do not let the term invasive fool you, negative consequences don't always follow the foreign additions made to these indigenous homes. Sometimes they are very much needed! Such as alien trees helping restore abandoned pastures and butterflies and their main food sources of foreign flowers. Some additions start off with good intentions and carry these plans out, but then proceed to start eliminate smaller native species and move on to young offspring soon after. This process, is when the new species becomes invasive.

Once a species is introduced to a new area, naturally it will spread by rivers, hitchhiking, and travelling on their own and other ways of dispersal. When a foreign organism enters a water system and starts to reproduce, it is next to impossible to get them out of the area, they can then dominate water ways, they out-compete, displace, or mate with the organisms that are preexisting in the area. Mating can permanently change the DNA makeup and is irreversible, this is called genetic polluting. This process can put some of the most abundant organisms on the endangered list, or in extreme cases, extinct. Some of the most popular negative invaders are; Snakehead Fish, Canadian Geese, Pythons, Asian Carp, African Honey Bees and Zebra Mussels.

But What Can Be Done???

•  pesticides- mainly used on plants and insects. But proven to be very effective when species is especially caught early.
• mechanical control- consists of manual work (pulling, catching, killing) ridding the species from the area. This can be a very lengthy project.
• ecosystem management- basically the whole land is set on fire and the naturally occurring species return to the area. This is a very new system though, so it is still being researched on how to control the flames as not to eradicate the species in that area completely.

'Tis the Season for FOOTBALL

So another homecoming has come and gone, but something about it was different... THE CLASS OF 2014 WON THE RED APPLE!

Now what is the red apple you might ask? Well it's basically Sparta's trophy to the class who shows the most school spirit, and gains the most points winning the friendly games created to get us fired up for the Homecoming Game. Now, unlike some schools; Sparta dedicates a whole day to listening to speeches of potential homecoming royalty, playing games, a Mock Rock competition, and ending with a parade to the football field with the floats we have been working on for the past couple weeks!

The positive energy is built up the more each student participates in the games. I personally participated in the Caterpillar Race, Kangaroo Hop, and Orange Pass. It is so cool to see every grade in each corner of the gym sporting their grade colors in the forms of bandannas, beads, and SPARKLES <3

The theme to the football game that night was blue and white out as it usually is. The Spartans won with a terrific lead of 41-14. Now that we are older, I enjoy cheering and standing in the student section, screaming chants with the possibilty of losing my voice for the day to come! But it is all worth it because the concessions have the BEST PICKLES!! The fireworks afterwards weren't too bad either. (:

The dance is always something to look forward to! It also helps that every year we get older, we look less awkward getting dressed up and posing for photographs. Haha, Saturday, I curled my hair and got all primped and ready for the dance. Later that afternoon my friend came over; and I got to do her hair as well! At around 6, the rest of the crew came over and we smiled for the cameras, posed for future memories, and said goodbyes to our parents. It was time for dinner after that, and there was Chicken Alfredo and  Caesar Salad. It was DELISH!

When  we got to the dance, we are greeted by our principal; sporting a tigers shirt, and the rest of the smiling Sparta staff behind him checking students in. We walk down the hallway and there was the usual DJ setup, but with a twist, there was fog and a laser light show. we made our way to the middle, and danced the night away. It was certainly a night to remember.

To cap off the night, my three friends and I went to Westgate and DOMINATED the glow bowl alleys and the pool room. What a last Homecoming to remember (:

#ALLISON

So I guess I never quite gave a summary about myself... Allison Miedzielec is my name and I am enjoying my time in bio so far(: I love that now that I am a senior, I get to take the fun classes and actually see where I can apply them in the world! I am hoping AP Bio will prepare me for what I need to get ready to take on when I hit college next year. I am looking at Northern Michigan University for psychology and for its beautiful scenery. I am in NHS and I just joined the little Spartans committee, I was in blood drive but I wanted to get more involved with the youth! I play volleyball and softball, I'd have to say I like softball a little better because you get those Oh-So-Wonderful farmer tans and enjoy all types of weather. I have two dogs and a sister. I know I should say I like my sister better but my puppy is a cuddler. Cant say the same for my sister. haha(:

so that's me. read and enjoy.
or don't.
that's a choice too.

Allison ☻
