Scavenger Hunt #1 Amanda W.

Photo 1: Homeostasis- Homeostasis is controlled by the temperature of the body. When a person's body temperature is lowered to 91 degrees Fahrenheit they suddenly develope hypothermia. This is an example of an uncontrolled homeostasis. I used a thermometer at 85 degrees Fahrenheit to symbolize the uncontrolled homeostasis.

 Photo 2: Pollinator- A bee is an example of a pollinator because they transfer pollen from an anther to the stigma of the flower.

 Photo 3: Autotroph- Bermuda Grass is an example of an autotroph. An autotroph developes energy by photosynthesis and also produces food for themselves.

 Photo 4: Heterotroph- My dog Molly is an example of a hetertroph becuase she can not produce food for herself. Heterotrophs are the predators.

Photo 5: ATP- Adenosine Triphosphate is used as a source of energy for many metabolic processes. It is found in the mitochondria of plants and animal cells. Muscle contraction which is what my leg is supposed to look like is one of the many metabolic processes. Side note:(As you can see I still have a dancer foot Mrs. Lory, some what, but not the calf muscles anymore!:) Sad day haha!)

Post for Friday the 29th (I will be in Nicaragua!!!)

Grouping: Organisms on different levels of the same food chain

Photo 6: This is Brumuda grass (located in my backyard, and the backyard of many others). It serves as the primary producer in this food chain. Grass produces its own food.

Photo 7: This is a camel cricket. It serves as the primary consumer in this food chain. Crickets are heterotrophs who eat plants.

Photo 8: This is a green tree frog. Their scientific name is Hyla Cinerea. They are secondary consumers in this food chain.

Photo 9: This is snake way back under the tree branch. Snakes serve as tertiary consumers in this food chain as snakes are a huge predator of frogs. This food chain proves to show that an animal doesnt have to be a huge lion to be a tertirary consumer.

(I had to stop my food chain here because I did not plan on spotting a hawk or coyote which both eat snakes any time soon..)

Photo 10: Flower Ovary-- A flower ovary is the part of the reproductive organ of the flower. It is located near where the sepals and the base of the petals meet. Right above the ovary is the stigma where the pollen is. This is my Begonia plant. It is looking very pretty and blooming lots of flowers!!
Pollen-- Pollen is the yellow powdery stuff in the middle of the flower buds on several plants and flowers. It contains microgametophytes which has the sperm cells from males. When it lands on a female cone, it germinates. Gametophytes-- are what produce male or female gametes by mitosis. It is the haploid cell. The male and female gametes coming together produces the diploid cell.
Pollinator-- There is a third party involved in flower and plant "mating." A pollinator has to come along and carry to pollen from one flower to another. This pollinator is some kind of insect, and it many cases it is a bee.

Carrie Riley...

Nicely done from one of our two seniors!  So Carrie has set the bar and given a nice example of how to post her photos. Remember your use of humans is limited... so use them wisely... haha.  Notice how she defined her use of the photo/vocab.  Can't wait to see your other pics, people.  I also assume you'll find some really nice biome/plant stuff in Nicaragua, Carrie.

Post For Friday the 22nd

Photo 1: K-Strategist-- A buffalo is a k-strategist because they have a smaller but stable population. They are also classified as this because they have a larger body and produce few offspring. I took this picture at Yellowstone National Park.
Heterotroph-- A buffalo, and all animals, fungi, and many bacteria are heterotrophs that cannot fix carbon, so they must use organic compounds as a carbon source and energy source. They break down complex organic compounds like carbs, fats, and proteins that were orginally produced by autotrophs into simpler compounds in order to recieve the energy they need to thrive. Autotrophs on the other hand can form organic substances to use as energy from inorganic substances like carbon dioxide. Autotrophs are plants, and algae, and any other producer.

Photo 2: R-Strategist-- This is a picture of a mouse; mice are classified as R-Strategists because they have smaller bodies, rapid maturation, and they produce a large amount of offspring at one time. This is a picture of a mouse for sale at petsmart.

Photo 3: Prokaryote-- This is a picture of a colony of bacteria taken at Yellowstone National Park. Bacteria is an example of a prokaryote because it lacks a cell nucleaus and is a one celled organism.
Unicellular Organism-- Prokaryotes are single celled organisms as I mentioned above. They consist of only one cell. Bacteria tends to live in colonies, like pictured above, but that is just a colony of many single celled prokaryotes. Each cell carries out the life processes needed to survive. Most protists and some kinds of fungi are also unicellular organisms like prokaryotes.

Photo 4: Eukaryote-- This is my cat Bentley. He is an example of a eukaryote because he is an organism that contains many complex structures with membranes around them. All species of large complex organisms are eukaryotes.

Photo 5: Cellular Respiration-- These are my cousins. Humans gain their energy through the process of cellular respiration as plants gain and make their own energy through photosynthesis. Cellular Respiration is the reverse of photosynthesis. There are three main steps of cellular respiration: gylcolysis, citric acid cycle, and electron transport.
ATP-- ATP is produced in all living things in the mitochondria. It carries and stores energy in the body, but is not energy itself. It consists of phosphate bonds. A third bond must be created in order for the energy process to start.That third bond breaks and energy is released that fuels the living organisms. ATP is produced by cellular respiration in humans. However, it is produced by photosynthesis in plants.

                                  

The hot zone

I have started to read my copy of the hot zone and I HEED you to be prepared to read very graphic and what some may find disturbing! Just warning all of

Waterfall - Costa Rica

OOPS! my bad... first blog entry not DUE until NEXT Friday. You just need to start collecting your photos this Friday.... ( I am old and feeble minded)

Hey APbio fans... if you are reading this it is because you are a follower and hopefully if you signed on as a contributor you are also seeing this post.  If you have signed on as a follower and NOT a contributor, please do so sooner rather than later (just got you, Tyler).  That way you can create your first post that is due THIS FRIDAY and read others' posts....
I just got back from a weekend at Lake Blackshear- very fun but I think I broke myself tubing.... can anyone tell me any bio facts about the area? types of trees, how lake formed, wildlife,????? look it up!  -Ms. P http://www.georgialakeinfo.com/blackshear/
