Transcript of AP Bio Final Scavenger Hunt 2014

7AM START TIME :)!!!
The Biology Galleria
Presented by David Traver, Vijay Joshi, Aria Farahani, and Dennis Bremer

Prokaryotic Cell
Collected by: Dennis Bremer
Collected at: Dennis Bremer's House
Collected on: May 17, 2014
The bacteria in yogurt, such as Lactobacillus bulgaricus and Streptococcus thermophilus, are essential for the fermentation of milk into the yogurt product. These bacteria are prokaryotic cells which are present throughout the yogurt medium.
Holy neek neeks!
Loud. Like Ms. Ward loud!
Selective Permeability
Collected by: David Traver, Aria Farahani, Vijay Joshi
Collected at: Room 327
Collected on: May 19th, 2014
The top picture depicts a dialysis bag filled with a water and starch solution before it was submerged in a beaker filled with water and Lugol's solution. The bottom picture illustrates the dialysis bag's contents after several days in the solution. Lugol's solution turns dark blue in the presence of starch, as shown in the bottom picture. Hence, Lugol's was able to pass the dialysis bag membrane and react with the starch solution. This portrays selective permeability because the starch was not able to pass through the dialysis bag membrane and out into the surrounding yellow solution of water and Lugol's. If it were able to pass, the beaker's solution would also be a dark blue.
Hmmmmm
I didn't hear a word you just said
I'm getting goosebumps
Diffusion
Collected by: Aria Farahani, Vijay Joshi, Dennis Bremer
Collected at: Dennis Bremer's casa
Collected on: 17 de mayo 2014
Diffusion is seen in the video as the dye starts as a concentrated droplet, but spreads throughout the water medium. Diffusion slowly starts when the drop hits the water surface, but occurs at a faster rate when stirred.
Didjya learn something new?
Did that help?
Come on people!
Potential Energy
Collected by: Aria Farahani, Dennis Bremer
Collected at: Aragon softball field
Collected on: 19 de mayo 2014
This isn't a trick question!
Does this make a little more sense?
Cell Signaling
Collected by: Aria Farahani, Dennis Bremer, Vijay Joshi
Collected at: Dennis Bremer's House
Collected on: 17 de mayo 2014
Bad juju
Plants are chemical terrorists
The leaf is exhibiting cell signaling by causing a specified part of the tissue to die off, as seen by the brown spot. This is likely due to an infection that causes the infected cells to signal nearby cells to die off. Hence, the resulting brown spot is a result of cell signaling to "self-destruct".
Diploid and Haploid
Collected by: Aria Farahani
Collected at: Aria Farahani's House
Collected on: May 23rd, 2014
On the right is the pollen found in a male pine cone. Pollen is haploid, while on the other hand, the actual pine cone on the right, which is female, is diploid.
Someone Ms. Warded
Would you like to phone a friend?
Homologous Chromosomes
Collected by: Aria Farahani, Dennis Bremer
Collected at: Room 327
Collected on: May 20th, 2014
Homologous chromosomes is a set of of one maternal chromosome and one paternal chromosome that pair up with each other inside a cell during meiosis. These copies have the same genes in the loci.
And it goes a little something like this
So folks, let's chat
RNA & Transcription
Collected by: Aria Farahani, David Traver
Collected at: Room 327
Collected on: May 23rd, 2014
Hey hey hey! What did I tell you guys?
And that's why I get paid the big bucks
Protein & Translation
Collected by: Aria Farahani, Vijay Joshi
Collected at: Room 327
Collected on: May 23rd, 2014
During the process of protein translation, the tRNA transfers mRNA through the rRNA, where the ribosomes clamps onto a mRNA template and begin to read the three base pair codons and start to form a polypeptide chain by producing and linking amino acids together. The polypeptide chain is then folded and a protein is formed.

Babies are parasites
Do you fondle gonads?
PCR
Collected by: Aria Farahani, David Traver
Collected at: Room 327
Collected on: May 22nd, 2014
Both the red and white circles made of paper clips are substituting the places of DNA. PCR is meant to come in and select a specific fragments of the DNA, remove it from the circular DNA, and transfer it to the red circular DNA. The red circular DNA will later be used as a template to form new proteins.
Don't copy this all down
So far so good?
Phloem
Collected by: Aria Farahani
Collected at: Softball Field
Collected on: May 16th, 2014
[Insert Description Here]
Let's face it folks
In all honesty
Pollinator
Collected by: Dennis Bremer
Collected at: Dennis Bremer's House
Collected on: May 20th, 2014
Hummingbirds carry pollen from the male anthers of a flower to the female stigma so that the plant can accomplish fertilization.

Inflammatory Response
Collected by: Aria Farahani, David Traver
Collected at: Room 327
Collected on: May 22nd, 2014
A bug bite can trigger an inflammatory response in which chemicals released cause blood vessels to leak fluid into the tissues in order to isolate a threat. This results in the reddening of skin around the bite as well as slight swelling at the site of the bite.
Smile and nod
Here's the deal

Collected at: Dennis Bremer's House
Collected on: May 17th, 2014
Do you follow how this is working?
Moi importante!
Evidence of the Five Senses
Hearing
The ear detects vibrations(the cymbal crash) and sends the information to the brain, signaling muscles to flinch.

Smell
Olfactory receptors in the nose transduce chemical messages into neural ones that can be sent to the brain, which in turn can signal for the mouth to salivate.
Taste
Taste buds in Vijay’s mouth transduce chemical signals into neural signals that are then sent to the brain, releasing dopamine to signal pleasure and comfort.
Sight
The visual stimulus of the ball is transduced in the retina into neural impulses that the brain can interpret, signaling muscles to contract and perform an action.
Touch
As Vijay’s hand touches the stove, the high temperature of the pan is detected by the skin and sent to the brain, signaling muscles to contract and quickly pull away from the source of heat.

Operant Conditioning
Collected by: Dennis Bremer, Vijay Joshi
Collected at: Dennis Bremer's House
Collected on: May 17th, 2014
Operant conditioning is illustrated through Dennis' dog performing a handshake. After the dog sees the treat in Dennis' hand (1), it recognizes Dennis' hand reaching down for the desired action (2), and responds accordingly with a handshake (3). Rewarded for obeying the command, the dog is given the treat, hence being conditioned to perform the handshake in return for a positive reinforcement.

Food Chain
Collected by: Dennis Bremer
Collected at: Ralston Avenue
Collected on: May 17th, 2014
The deer is a primary consumer. It feeds on primary producers, which in this particular picture is the grass, which in turn gets its energy from the sun.

Ecological Disturbance
Collected by: Aria Farahani, David Traver
Collected at: Center Court

Out with the bad
In with the good air
Ecological Problem
Collected by: Aria Farahani, Dennis Bremer
Collected at: Softball Field
Collected on: May 16th, 2014
Litter, as shown by the plastic bottles, is an ecological problem due to its long decomposition time and threat to wildlife. Plastic bottles, for instance, can get stuck around animals' necks, resulting in suffocation or strangling.
You guys will be fine
Solution to an Ecological Problem
Collected by: Aria Farahani, Dennis Bremer
Collected at: Softball Field
Collected on: May 16th, 2014
Drought is the lack of natural rain, and the solution to this is sprinklers. Sprinklers are used to water plants and vegetation in seasons in which rain is less common, like Summer (almost there, woohoo!!).
Water is important in photosynthesis as it splits into oxygen, hydrogen ions, and electrons to replace the lost electrons of photosystem II in light-dependent reaction. Also, as hydrogen ions pass through ATP synthase, ATP is formed to use in the light-independent reaction.
You guys are AWESOME!
GO BIO!
When Dennis' arm is in the full back position it has stored energy in the form of ATP waiting to be used. In addition, the action potential in the nerves has potential to go above the threshold and signal for the arm to fling forward.

The pipe cleaners are substituting as part of a DNA segment. The koosh ball represents RNA polymerase and is seen unwinding the DNA, and as it moves along the double helix, it pairs the equivalent RNA base pairs to the DNA strand to produce a mRNA molecule.
The phloem in the tree trunk transports sap. The leakage of sap in this tree is most likely due to a mechanical injury.
The paved pathway creates a divide in the grass field such that the grass on one side can not physically connect with grass on the other side. Similarly, an organism on one side may be unable to physically interact and come in contact with an organism from the other side, as portrayed by our fine young models.

THANKS MS. WARD FOR A WONDERFUL YEAR!!!
