flat Blog: https://podcast.punxsy.k12.pa.us/users/13giavedoni_heather/ =About Me= My name is Heather and I am 15 years old. I have one sister and I live with my dad. I go to the Punxsy Area High School and I am in the tenth grade. When I grow up I want to be a Pediatrician because I l love to work with children. If I could have one thing in the world I would want the biggest pack of colored pencils there is because I love to draw, sometimes I draw so much that my hands turn black from shading things. Iam very easily amused person and I'm not good at concentrating on things. I would rather read a good book than watch television. I through discus and shot put in track and field its the only sport I play. I'm a very head strong person when I have an opinion on something everyone knows it. I love watching movies and talking to my friends my two grandmothers are the best people in my life and I tell them everything. I don't like when people act like there two years old just to get what they want I can't stand when people constantly tap there pencils or fingers on there desk and I really don't like talking about myself so I think thats it. Thanks for reading my page and about me.

 * Activity 1: **
 * Background information**

Go to the following page and complete the quiz: []
 * Activity 2: **
 * What microbe are you?**

1. When finished take a shot, or copy and paste the information about the microbe most like you. Trichodesmium erythraeum 2. View the dichotomous key provided by your teacher. Answer the following: a. How are the steps in the dichotomous key organized? They are organized by what they have in common with each other. b. What is the purpose of a dichotomous key? To help us understand how microbes are organized and related to each other c. What characteristics were used in the steps of the dichotomous key? How organized or disorganized a microbe is or whether or not it like to be with others or alone amongst other tings. d. Which bacteria are you most closely related to? solitary e. Which bacteria are you most different from? One of the one from the Eukaryotes. =Biomolecules=

1. What kinds of biomolecules are in each of the food substances you tested? The food that I tested was peas and the biomolecules that I found that there was not simple sugars, but there was a presence of starch, fat and protein. 2. Do certain biomolecules have the same catalase reactions? Explain. Yes because if they didn’t then during the catalase test peas would have had different reactions to the different temperatures of hydrogen peroxide. 3. What other results did you observe in the class that can be used to make a statement of what you have learned? Even though everyone had different answers whether in absent or present in carrots and peas the answers were mostly the same. In peas there was some debate on whether there was simple sugars or not the results came out as fifty, fifty so I went with researching and I found that peas do not have simple sugars in them.

What do enzymes do to your food? Enzymes come from the pancreas to digest your food and help. After they are done with food they go through out you body to help get rid of irregular cells like bruises or cancerous cells. =Chromatography Lab= We got a single pigment from the leaf we used for this lab.Our Rf value was .58 the solvent front was 3.4 cm and the pigment front was 2 cm. the fact that we had something so different from the other group who had three different pigments shows that every plant is different and does not show the same chemicals as the other plant. =Light Intensity Activity= In conclusion we found that with a lower wavelength and higher light intensity you will get a better percentage of ATP.
 * 1) Discuss your results from the activity, discuss your analysis of the activity from the spreadsheet (what did you learn, what was surprising, what connections can you make between temperature and enzyme activity and the presence of catalase in certain food? I did peas and I found that there was no reaction in the catalase lab. Temperature is important because it has different effects on the enzymes.
 * 2) Show the chart that you created.
 * 3) Develop a question about the catalase activity. Create a quality question about enzymes or enzyme action, etc. Either research to find the answer or use available materials to experiment to find the answer. If you research, list your sources. If you experiment, outline your experiment and explain your results.

=Yeast Respiration Lab= The lab is where you take yeast a sugar solution and warm water to mix together to find the reaction it has and what kind of environment yeast prefers. Yeast prefers to be in a warm environment to cold this is because it's reaction only occurs in warmer areas. A dependent variable depends on other variables to get some of the things that it needs.Yeast is also an anaerobic respiration solution because it doesn't need oxygen to have a reaction. An aerobic respiration process is when the reaction you get does need oxygen. The independent variable is what the dependent variable depends on. The independent variables in this lab are water oxygen and the percentage of sugar solution used. The dependent variables are the yeast and the balloon. The sugar solution percentages were 3%, 5%, 7%, and 10%. Each of these percentages, even though we used the same amount of each, effected the yeast differently then the others. We saw an almost immediate reaction with the ten percent mixture, but with the three percent mixture we saw little to no reaction at all. I did the five percent mixture and there was a very small reaction created as shown in the pictures below. My circumference of the balloon was 4.75 inches. The over all volume of the gas in the balloon was 1.98 cubic inches. In conclusion I feel as though you can not get accurate volumes of gas because of the cold and that there would be a higher volume of gas if the temperature was warmer. ====== When first added water and yeast Ten minutes after first recording Thirty- five minutes after first recording 24 hours after first recording



=Venn Diagram on Cell Respiration=



=DNA Replication Model= Green- adenine Orange- Thymine Red- Cytosine Black- Guanine Blue- Sugers that are Dioxyribose and phosphates

DNA is the part of the cell that makes up the chromosomes, they also hold the genes that make up your character and other things like your hair color and eye color. But DNA also replicates by steps and the beginning step is that the DNA unwound. The second stage is the split then copies are made during stage three. The fourth stage is when replications are made of part one and part to so that you come up in the end with the two side that are bonded with hydrogen bond. In the last part of DNA replication is the rewinding the two new strands of DNA.

=Class Traits Lab=

The two traits that I will be focusing on are Ear lobes and Dimples. In earlobes you see that with more people that it actually looks like attached earlobes are dominant. In reality they are not free earlobes are dominant. With dimples it looks like they are a recessive trait. Dimples are a dominant trait though. How do you tell which is recessive and which is dominant? What else is there that determines a trait other than your parents? ** You will need to determine the total of girls that have the trait/don't have and the total of boys that have the trait/don't have. You will also need to determine the total of all who have the trait/don't have the trait. In the end you will need to determine what is dominant and what is recessive (the trait that has the most numbers is not always dominant!). ** Doing additional research here is recommended such as chromosome location, facts about the trait, etc. Short second finger is a dominant trait but looking at the results of the class the numbers it looks like it is. Their eight girls with this trait and three boys with this trait also, there are thirteen girls and five boys in our class. In total eleven out of eighteen students have a short second finger. The no long palmer muscle trait is also dominant. Nine out of thirteen girls and three of five guys have this trait. Twelve of eighteen students in our class do not have a long palmer muscle. So having a long second finger and not having no long palmer muscles are a recessive gene. My genotypes and phenotypes for lets say rolling tongue is RR or Rr because both of my parents could roll their tongues. My parents could also be RR or Rr because of the genes of their parents. My sister is either RR, or Rr because she also can roll her tongue. If I was Rr that means I got the big R from one parent and the little r from another.
 * 1)  Focus in on 2 or more of the traits, whether they are dominant or recessive, and whether the numbers portray them as dominant or recessive.
 * 1)  What statements or questions can you make about the data as well as the comparison of data between our classes and elsewhere. Doing additional research here is recommended such as chromosome location, facts about the trait, etc.
 * 1)  You will also look at 2 other traits not used on the site that we looked at in class.
 * 1)  Discuss your genotype and phenotype with one of the traits and discuss the possible genotypes of your parents/siblings. I am looking that you can identify the possibility of receiving certain alleles from your parents and that you understand the laws of segregation and independent assortment.
