SURVIVAL OF THE PEOPLE WITH THE HIGHEST GRADES(KIND OF NOT REALLY)

Today we reviewed our homework's reading on why everyone has to die and human aging. It talks about how aging was programmed into us and how we are all destined to die. Pretty much what happens is that everytime a cell reproduces, it loses a bit of DNA, however, in order from preventing the reproduction from doing damage to your body, your DNA have telomers which is pretty much blank data that is used up during reproduction and once the telomers on DNA run out, your body starts getting damaged. The reason why we have this process is an attempt to get fight back against cancer. When a cell becomes cancerous, there is a limit to its ability to reproduce which prevents the cell from growing outrageously. In this way, cancer cells will die out after the telomers are used up. However, cancer cells have a way around that but essentially, this process is a way to prevent cells from easily taking over and reproducing in your body. Also, another reason why we have aging is because dying at an old age does not prevent us from reproducing and thus keeps our species surviving. As long as we reproduce, our bodies don't care what happens to us after we reproduce.

THANK YOU SO MUCH BODY.

Masculinity and how sexy it truly is

Today, during parents day, we had to rate the attractiveness of a number of guys and girls with slightly changed features. Each guy face and girl face was slightly more masculine or feminine than the other and we figured out who thought which face was more attractive to them, masculine or feminine? Although many faces, to me, looked like the same (some were the same because there needed to be a control in the experiment), I figured out that I liked more feminine faces compared to masculine in both guys and girls just like almost all of my classmates. We conjectured, MAYBE IT WAS BECAUSE FEMININE FACES ARE MORE ASSURING AND "SAFER". SOFTER FEATURES SHOWS A MOTHERLY PERSPECTIVE AND A MORE TRUSTWORTHY PERSON THAN A MASCULINE PERSON. So apparently, I like more trustworthy looking people rather more masculine looking people who seem less trustworthy. Mmhmm. Good stuff Mr. Quick

1. This diagram shows how a certain organism can evolve over millions of years into something completely different yet have some certain similarities. The Mesonychid, in an attempt to find less competition on land, evolves to live in water where there are less predators and competition for it to survive. It still keeps certain structures similar however such as the one bone-two bone-many blobs structure that can be found in the mesonychid as well as in the Basilosaurus.

2.North America

3. Dragonflys, BIrds, and Bats all show analogous structures in their evolution because the bone structures found within them are completely different but the function of their wings are the same. To fly. These organisms, although do not have a common ancestor, all evolved a similar body part to help them preform a similar function

4. The common descent lab shows the different cytochrome C sequences of every animal. Cytochrome C controls the number of random mutations a certain animal has and when there are less differences between two organisms, that means they are related more closely. Humans and rhesus monkey, have only one difference in their Cytochrome sequences whereas Humans and horses, have around eight differences which is why they are less closely related than Humans and rhesus monkeys.

5. Homology is when there is a structure that is similar in many organisms. This is made possible because they all these organisms with the same structure came from a common ancestor who had the structure. For example, Humans have the one bone-two bone-many blobs structure as well as chickens and bats. They are all related from a common ancestor who began to have the one bone-two bone-many blob structure

DAY TWO OF NEW UNIT YEAHHHHHH

TODAY WE CONTINUED ON WITH THE EVOLUTIONARY STUDIES. THIS TIME WE WORKED ON A WORKSHEET WHERE we looked the differences in amino acid sequencing between different organisms and with the number of differences, we were able to put organism in order on a FAMILY TREE BY PUTTING DONKEY AND HORSES TOGETHER BECAUSE THEY ONLY HAD 1 difference in amino acid sequences AND THEN PUTTING THE MOST DIFFERENT ORGANISM, YEAST AS FAR FROM THAT AS POSSIBLE. THE REASON WHY WE LOOK AT AMINO ACID SEQUENCES IS BECAUSE THESE SEQUENCES ARE FOUND ON DNA AND CONTROL THE AMOUNT OF MUTATIONS THE ORGANISM HAS SO LESS DIFFERENCES MEANS THEY'RE NOT THAT different. 

BEGINNING OF NEW UNIT

TODAY WE STARTED ON A NEW UNIT. FOR HOMEWORK WE WERE SUPPOSED TO READ CHAPTERS 1, 2, AND 11 ON YOUR INNER FISH BUT I ACCIDENTLY READ CHAPTERS 1,2 ON SURVIVAL OF THE SICKEST BEFORE I REALIZED I WAS READING THE WRONG BOOK. MR. QUICK PLEASE EMPHASIZE INNER FISH NEXT TIME THE BOOKS LOOK THE SAME. The chapters essentially talked about the Tiktaliik and how it proved evolution because it was a transitional fossil that had characteristics of a fish and an amphibian which shows how certain species evolved to get onto land. We also learned how animals are related to each other through a common ancestor through their homologous structures. The appearance of two bones on limbs are common through most animals because although they all look completely different, they came from the same ancestor probably millions upon millions of years ago.

MACROMOLECULE LAB

Macromolecule Lab


Today we worked on a Macromolecule lab where we were attempting to find the culprit who stole Jerell's ipod. The way we went about this was every culprit had something different for lunch and we tested different foods such as jelly, pretzels and yogurt for glucose, starch, glucose, and lipids using different indicators: Biuret tests for proteins; Benedict tests for glucose; Iodine tests for starch; and we used a brown paper bag to test for lipids. After testing all the different food items for these items, we did the same process for the unknown substance that was supposedly found on Jerell's iPod. After much detective work, we found Amanda's food, contained, starch, glucose, lipids, AND proteins which was also found in the unknown substance that was obtained from the scene of the crime.

HI MRQUICK TODAY WAS A LAB DAY.

Today we did half of a large lab that worked around the properties of osmosis and diffusion. The first half of the class involved us working in groups of two and attempting to teach another group of two how diffusion and osmosis worked. So Raymond “Rattyray” Tang and I proceeded to teach Anita and Sean how diffusion and osmosis worked.

The second half of the class consisted of a very large lab. We did three parts to the lab. The first part was us putting five different solutions of different molarity into dialysis bags, measuring them, and setting them in distilled water for exactly twenty minutes. After the twenty-minute mark, we took the bags out and measured the weight of each bag and figured out the percent of mass change. We figured that the higher the molarity of the dialysis bag, the more mass change because there was more water that was needed to go into the bag in order to lower the molarity.

The second part we did was using Gatorade and different colored solutions. We placed 5 mL of Gatorade into cups of different colored solutions to find the molarity of the Gatorade. Because we knew the molarity of the different solutions, after we measured the percent mass change of each test, we were able to find the molarity of the Gatorade based on the molarity of the different solutions 

The third part involved the molarity of different potatoes as we put them in different solutions. We were able to do the same and figure out the molarity of the potato by graphing the results and figuring out when the 0 percent mass change happened at what general molarity.
