Auxin Producing Area of a Plant-The Auxin producing area of a plant is where the stem of a plant is growing, and buds form as the Auxin hormone promotes growth.

Epithelial tissue – This is Frederick Tran. Frederick Tran has skin, and skin is an epithelial tissue.

Pholem – The Pholem of a plant transports sugars and other molecules to every area of the plant. The Pholem is the inside layer of bark in trees.

 Xylem – The rings of a cut down tree show the layers of xylem built up year after year in a tree. Xylem is a system of transporting cells that circulate water and minerals. Every year, the Xylem tissue dies and then develops new, as shown here.

Endosperm- Endosperm is a tissue produced inside seeds during fertilization of many flowering plants that provides nutrition for the embryo. Many Endosperms are edible-including popcorn.

Adaption of an Animal – This Gerenuk at the Fort Worth Zoo has a curved spine that enables it to reach substance up high in trees.

Pollen – Microscobes shed from anthers called pollen need to be spread to the stigma of other plants to reproduce.

Kreb’s Cycle – The Kreb’s Cycle is a part of a plant’s cellular respiration in which two molecules of pyruvic acid formed in glycolysis are used and yields high-energy molecules of NADH and FADH.

K-Strategist – Birds are K Strategists. They lay a few eggs and care for their young after they hatch.

Frond – Although this fern is dead, the leaves of ferns are called fronds and are large and divided.

Asexual Reproduction – Plants produce asexually. They rely on other creatures to pollinate them to reproduce.

Hydrophobic-Oils, such as vegetable and olive, are hydrophobic substances as they do not mix with water.

Hydrophilic-Juice can be considered a hydrophilic substance because it can mix with water.

Long Day Plant – Potatoe plants are examples of long day plants because they form flowers only when the day exceeds 12 hours.

Mating Behavior – These birds are exhibiting mating behavior. The one on the right is trying to fluff himself up and appear bigger, a sign that he wants to mate. The chirps of the birds was another indicator as well, but that does not come across in a photo.

Hot Zone Part Four Comments: The last part of the Hot Zone is about the author going on his own exploration of Kitum cave with his own equipment, and guide. I felt that sharing his story with the readers was a good way to tie the novel together, as the book started with the story of Charles Monet who died of something he more than likely contracted in the cave. The end does not seem very optimistic, as Preston explains that dieases like Ebola can mutate and will more than likely show its face again sometime. The best we can do is continue to study these hot agents and hope to learn enough about them that we can know the dangers.

ATP-ATP is an organic compound that contains chemical energy that when broken down helps contribute to metabolic processes. In plants, ATP is in the chloroplasts during photosynthesis.

Bilateral Symmetry – This dragonfly has bilateral symmetry. One could draw an imaginary line down the center of the creature and half close to a mirror image on either side.

R Strategists-Fish are R-Strategists. They produce many offspring that they do not tend to in the hopes that a few will be strong enough to survive. These fish are from the Dallas World Aquarium.

Mutualism-The minnows that live in the pond in my backyard have a mutual relationship with my family. We allow the minnows to live there, while they benefit from eating Mosquito larva in the pond and we benefit from the smaller mosquito population.

Calvin Cycle-The Calvin Cycle occurs in the stroma of chloroplasts during photosynthesis. The energy produced from ATP is used to convert Carbon Dioxide and other molecules into organic substances.

Segmented Body-This ant has a segmented body. The segmentation allows for specialization is certatin regions of the body and allows them to have efficent movement.

Fermentation-Cheese undergoes fermentation. Fermentation is a process by whish organic foods are converted into simpler compunds and ATP is produced. The creation of cheese relies on the fermentation of lactose by lactic acid bacteria.

Lipid- Nuts, such as cashews, are made up of lipids. Lipids are insoluable in water, and can range from fats to waxes; they help to store energy in the body.

Amniotic Egg-Some animals, like chickens, hatch from amniotic eggs. Had these eggs been fertilized, they too could have produced baby chickens.

Ethylene-Ethylene is commonly used today as a plant hormone. It can help stimulate and regulate the ripening of fruit, such as this apple.

Part 3 of the Hot Zone:

Part 3 of the Hot Zone was all about the military’s operation inside the monkey house from killing the remaining animals, to collecting samples, to decontaminating the building. The job seemed overwhelming at first, with hundreds of monkeys needing to be put down, but the process went fairly smoothly with everyone being as caustious as possible by operating in their space suits and decontaminating themselves and their equipment frequently. Although it was interesting to hear about the process of tackling the Reston Monkey House, I felt that this section got fairly dull at parts. As readers, we had already gotten a look at the how seriously the army takes Level 4 Hot Agents, and I felt that a complete overview  of the Monkey House scenario was rather redundant [and a tad overplayed on the cover of the book.] I was expecting the situation to be a much more pressing issue, but it seemed in the end that this particular strain of virus only brought serious harm to monkeys, which perhaps is good for us humans, but does not make for the best story if you know what I mean. I still felt that this has been a good read because it so different than what I usually read and the writing style keeps the readers attention.

Population-This hornet’s nest is an example of a population. They have created their own community where multiple hornets live and work.
Detrivore-This baby worm is an example of a detrivore. He obtains his nutrients by decomposing organic matter.

Niche-This bunny has created his own niche in the park. He lives among the bushes, and is able to feed off the food tourists drop.
Meristem-Meristem is the tissue from which new cells are formed. In the tip of this bush the meristem keep the branches growing outward and multiplying.
Adaption of a plant-This plant has leaves with sharp points to discourage creatures from coming near it. This protects the plant and proves effective in warding off pests that may harm it.

Lindsay Kelly Week 4 Posts-All of the captions are being strange!

Analogous Structures-The wings on birds, such as this goose, are considered analgous structures because different species have the same or similar wing function but may not be from the same evolutionary orign as this goose.
Captions:Cuticle Layer of a Plant-Leaves, such as these vine leaves, have a waxy layer covering them called the cuticle layer. This layer helps prevent water loss, and protects the leaves. Parasitism-This plant is a parasitic relationship with some insects. The plant is being destroyed while the bugs devour it for food.”] Homeostasis-This squirrel is in homeostatis. He has inner stability and maintain a stable condition.
Hot Zone Part 2 Comments:
The second part of the Hot Zone was more focused then the first. It follows the story of a monkey testing plant that begins to show signs of sickness. All sorts of people become involved with the problem of the Monkey House in Reston, as the dead monkeys cells have to be examined and tested. When the cells test positive for Ebola Zaire, a dangerous virus that is rather unknown and until this point, only found in Africa, people go into a panic. No one is quite sure what the virus is capable of, or who should be in charge of the operation. I found that this part had more of a story line made it easier to follow then the first. The reader still gets to see each person’s role in the scenario, and their point of view, but each person’s story combines to create the overall event. I find it funny [maybe that’s not the right word] that each person who is pointing out the dangers of the virus say that it is so close to Washington.  I guess Washington is argueably, America’s most important city, but perhapsit would be more troublesome if the virus was near a more populated city.

CAM Plant-This Cholla Cactus is an example of a CAM Plant. It uses the CAM to adapt to arid conditions. CO2 is converted to Oganic Acids, then

Radial Symmetry- This starfish from the Dallas World Aquarium has radial symmerty. It can be theoretically be "cut" to produce a mirror image.

Ectotherm-This fish, also at the Dallas World Aquarium, is an example of an ectotherm. Ecotherms cannot control their body temperature, it changes depending what kind of enviornment it is in.

Gymnosperm leaf-This is the leaf of a gymnosperm. Pine trees are conifers, their leaves are one single unit, and needlelike.

Anther & Filament- The anther and filament of these flowers are visible. The anther contains the pollen sacs that release pollen to be dispersed and the filament holds the anther.
