today in science we did a lot of things starting off with learning about the difference between a reactant and a product and we found out that a reactant is the begging of the process or the starting point and a product is the ending point of the process. but that is not all we did we also had a few minutes to fill out this paper about the different qualities of photosynthesise and cellar respiration. And i found out that photosynthesise changes sunlight into chemical energy and the cellar respiration uses oxygen to release energy. But they have some things in common like they are both processes in different living things. So after that the period was pretty much over.


If you are curious about the exact definition of cellar respiration read below

Cellular respiration is the set of the metabolic reactions and processes that take place in organisms' cells to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions that involve the oxidation of one molecule and the reduction of another.
Nutrients commonly used by animal and plant cells in respiration include glucose, amino acids and fatty acids, and a common oxidizing agent (electron acceptor) is molecular oxygen (O2). Bacteria and archaea can also be lithotrophs and these organisms may respire using a broad range of inorganic molecules as electron donors and acceptors, such as sulfur, metal ions, methane or hydrogen. Organisms that use oxygen as a final electron acceptor in respiration are described as aerobic, while those that do not are referred to as anaerobic.
The energy released in respiration is used to synthesize ATP to store this energy. The energy stored in ATP can then be used to drive processes requiring energy, including biosynthesis, locomotion or transportation of molecules across cell membranes. Because of its ubiquity in nature, ATP is also known as the "universal energy currency".

also i think this was for extra credit C6H12O6 (aq) + 6O2 (g) → 6CO2 (g) + 6H2O (l) Cellar
respiration

and for photosynthesis 6 CO2(g) + 6 H2O(l) + photons → C6H12O6(aq) + 6 O2(g)carbon dioxide + water + light energy → glucose + oxygen + water

i got all of this information on en.wikipedia.org/wiki/Photosynthesis - 142k

Today in science we did not do that muchwritten work but verbally we learned a lot. in the begging mr.finley checked our homework and we also went over it and while we where going over it we all learned that when someone is talking and telling you information you remember it a lot better thenwhen we read information. So anway later in the period Mr.finley tryed to show us how the glass of water with a whole on it can suchtion on to something so he tryed to do it but while he did it the book was to heavey so the water went everyware it was pretty funny, then he wanted redemption so he tryed it a gain but this time he got a a lighter piece of paper and he was succusfull. so that is about all that happened today. Have a good weekend!!

Today in science was an okay day. first when we walked into the door i was like ugh because i dont like subs. so after that she told us all that we had to do and so we got to iti actually learned a lot of things today about how does photosynthesis works i learned that it makes the co2 into oxygen and that the choloplasium gives it its green color. but anway we read a lot and at the end of the day we had to take a test prep and it was pretty easy. and thankfully i finished.

The exacted deffination about Photosynthesis below
http://en.wikipedia.org/wiki/photosynthesis
Photosynthesis is a metabolic pathway that converts light energy into chemical energy. Its initial substrates are carbon dioxide and water; the energy source is sunlight (electromagnetic radiation); and the end-products are oxygen and (energy-containing) carbohydrates, such as sucrose, glucose or starch. This process is one of the most important biochemical pathways,[1] since nearly all life on Earth either directly or indirectly depends on it as a source of energy. It is a complex process occurring in plants, algae, as well as bacteria such as cyanobacteria. Photosynthetic organisms are also referred to as

www.shvoong.com/exact-sciences/biology/1659046-chloroplasm/ - 75k
Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide to produce sugars, the raw material for energy and biomass production in all green plants and the animals that depend on them, directly or indirectly, for food. Chloroplasts capture light energy from the sun to conserve free energy in the form of ATP and reduce NADP to NADPH through a complex set of processes called photosynthesis. Chloroplasts are members of a class of organelles known as plastids

<--The results kind of looked like this but with different info

Today in science was a very exciting day because first when we came in Mr.finlley told us that the results of the DNA from the ap bio group finally came i was very happy because i have been waiting a long time:) So after that we got to look at the results and after a hard an good analisis we found out that Marc G was the thef. We found this out because since everyones DNA is different Marcs was the only one that matched up perfectlly with the sample hair. We had to come up with explations to explain our claim. Today in science was a great day but at the end of class shockinglly Mr.finlly told us that no one took the Moon rock it was just a myth.

The functional form of single stranded RNA molecules frequently requires a specific tertiary structure. The scaffold for this structure is provided by secondary structural elements which are hydrogen bonds within the molecule. This leads to several recognizable "domains" of secondary structure like hairpin loops, bulges and internal loops. There has been a significant amount of bioinformatics research directed at the RNA structure prediction

problem.en.wikipedia.org/wiki/RNA_structure

At the ends of the linear chromosomes are specialized regions of DNA called telomeres. The main function of these regions is to allow the cell to replicate chromosome ends using the enzyme telomerase, as the enzymes that normally replicate DNA cannot copy the extreme 3′ ends of chromosomes. These specialized chromosome caps also help protect the DNA ends, and stop the DNA repair systems in the cell from treating them as damage to be corrected. In human cells, telomeres are usually lengths of single-stranded DNA containing several thousand repeats of a simple TTAGGG sequence.
These guanine-rich sequences may stabilize chromosome ends by forming structures of stacked sets of four-base units, rather than the usual base pairs found in other DNA molecules. Here, four guanine bases form a flat plate and these flat four-base units then stack on top of each other, to form a stable G-quadruplex structure.These structures are stabilized by hydrogen bonding between the edges of the bases and chelation of a metal ion in the centre of each four-base unit. Other structures can also be formed, with the central set of four bases coming from either a single strand folded around the bases, or several different parallel strands, each contributing one base to the central structure.
In addition to these stacked structures, telomeres also form large loop structures called telomere loops, or T-loops. Here, the single-stranded DNA curls around in a long circle stabilized by telomere-binding proteins.At the very end of the T-loop, the single-stranded telomere DNA is held onto a region of double-stranded DNA by the telomere strand disrupting the double-helical DNA and base pairing to one of the two strands. This triple-stranded structure is called a displacement loop or D-loop.

Well today in science we did a lot of things like first when we walked in the class we talked about the different structure between RNA and DNA. but after that we watch a very detailed movie containi9ng all the different thing people found in DNA and RNA but we never got to finish. we watch that movie because it let us know really how they both work. i was happy we watched that because i was kind of confused about how the differnet parts match up but now it is really clear to me and also it was really funny today i had a dentist appotment and they had to take an exray so they put the hevey led thing over me and i was like i know why that is on me because it protects you from getting harmfull dieses from the exray like the person in the movie who died of cancer. over all today was a good day!!!!

Well today in science rigt when we sat down we were all talking about the homework that we did last night. we where doing this because that was very important and probally going to show up on a test or quiz so thankfully mr.finlley was perparing us .we did that for most of the period and we asked questions back and forth. I pesonally did not really understand the web site so i think that i am gonna go on it over the weekend so i have a better understanding of it. Mr.finlly also told us that the results from the AP bio group 0r something like that are almost done with the results of the DNA test of the moon rock. After we get that we have to see which persons DNA match up the best with the DNA sample(piece of hair) he found next to the scene of the crime so i am very anxious aboput that. well that is pretty much what we did today see ya monday!

Today in science it was not a good day because first i do not like subs and this one did not like me so after that we all sat down and took our test the test was kinda hard but i new some of it. then after the test we had about 15 minutes left so we decided to do our homework me joey c and todd work really good and we got a lot done

If you are curious i got a cool picture of the parts in DNA off of wikipedia

Animation of the structure of a section of DNA. The bases lie horizontally between the two spiraling strands. Large version

DNA is a long polymer made from repeating units called nucleotides.[1][2] The DNA chain is 22 to 26 Ångströms wide (2.2 to 2.6 nanometres), and one nucleotide unit is 3.3 Å (0.33 nm) long.[3] Although each individual repeating unit is very small, DNA polymers can be enormous molecules containing millions of nucleotides. For instance, the largest human chromosome, chromosome number 1, is approximately 220 million base pairs long.[4]
In living organisms, DNA does not usually exist as a single molecule, but instead as a tightly-associated pair of molecules.[5][6] These two long strands entwine like vines, in the shape of a double helix. The nucleotide repeats contain both the segment of the backbone of the molecule, which holds the chain together, and a base, which interacts with the other DNA strand in the helix. In general, a base linked to a sugar is called a nucleoside and a base linked to a sugar and one or more phosphate groups is called a nucleotide. If multiple nucleotides are linked together, as in DNA, this polymer is called a polynucleotide.[7]
The backbone of the DNA strand is made from alternating phosphate and sugar residues.[8] The sugar in DNA is 2-deoxyribose, which is a pentose (five-carbon) sugar. The sugars are joined together by phosphate groups that form phosphodiester bonds between the third and fifth carbon atoms of adjacent sugar rings. These asymmetric bonds mean a strand of DNA has a direction. In a double helix the direction of the nucleotides in one strand is opposite to their direction in the other strand. This arrangement of DNA strands is called antiparallel. The asymmetric ends of DNA strands are referred to as the 5′ (five prime) and 3′ (three prime) ends, with the 5' end being that with a terminal phosphate group and the 3' end that with a terminal hydroxyl group. One of the major differences between DNA and RNA is the sugar, with 2-deoxyribose being replaced by the alternative pentose sugar ribose in RNA.[6]

well today we did a whole bunch of things but first when we wlked into the classroom we took some notes about how we are going to do the experiment. then we got to it we swabed all of the criminals for five minutes on each side of the mouth so we where swabing for a total of ten minutes. so after that we brought out the test tube and put the swaber in there and squshed it around. aftere that mr.finlley brought out very dangerous rubbing alcohal to put in the test tube and then instantly when he did that our group saw the DNA that was in my mouth it was really cool. last to end the day we corked up the tube and gave it to Mr. Finlley to put away then off we went to lunch!!

What is DNA?

en.wikipedia.org/wiki/DNA - 318k

Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The main role of DNA molecules is the long-term storage of information. DNA is often compared to a set of blueprints or a recipe, or a code, since it contains the instructions needed to construct other components of cells, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.

I DONT HAVE THIS

Just starting the new unit on DNA coincidentally mr. finnelys moon rock got stolen and people think that it is me.(i do not like moon rocks) any way there was a piece of hair next to where the crime seen was. so he said that we are going to test everyones DNA and see witch ones mathch up. but then someone told him some clues about what the person looked like so he narrowed it down to like five people and of course i was in that group. but then today he made the group swab our cheack cells so i guess we are going to teat that.

This week in science we went over all of the cell parts in a animal cell and a plant cell it was good to do this because i forgot some parts but now after looking at the smart board i now remember them. we did this because i guess i was not the only one who forgot some parts so i guess mr.finely found that out so we had to go over it closing the unit.
