For you people who don't know, anthropomorphism means to apply human characteristics or behavior to non human animals or objects. In other words, to personify something. We applied this to our snails when we gave them four different kinds of food we eat to choose from. The food was from our lunches that we brought to school.

Did you know that the Madagascar hissing cockroach is native only to Madagascar? They can grow up to 3-4 inches and the males are very territorial and will fight each other like goats do. Their average life span is 2-3 years. Females only breed once in a lifetime but can have up to 3 litters annually. Their babies are called nymphs. The roaches have 6 sticky feet that they cruise around on.

What i know about cockroaches? i know that they are an insect, they're usually brown and can get to about 2-3 inches long. They are one of the most versatile creatures on the planet and have been known to survive nuclear events.I'd like to know why they can survive such things and how big the biggest cockroach is.

In our experiment, we put a snail in a box with 4 foods around it at an equal distance away. The foods were onion, ham, broccoli and a grape. we did four trials. the snail went for the grape once, broccoli once, and ham twice. So we've concluded that the snail prefers the meat. Our evidence is that the snail went to the meat 2 out of 4 times. We think the snail chose the meat because it smelled the strongest, besidesthe onion, which the snail avoided so we think it dosent like onion. One inaccuracy we might have had was the direction we placed the snail in at first might have influenced his choice.

K: I know that snails have a shell, they use their slime to move around, and i'm pretty sure they're a mollusk.They can live on land and in water depending on the species. W: i want to know if snails change shells like hermit crabs do, or if they're permanently attached.

Henry and I wanted to know how colored water would affect the color of the carnations that are in the water. Our experiment: we took two white carnations and split the stems down the middle up to about 3/4 of the way up. we then took four cups with different colored water. one had clear water, another green, and 2 cups had red. We put the two parts of one flower into the clear and red cups, and the other with red and green. we predicted that the flowers would absorb the colors and be a mix of the two colors. Our result was the flowers absorbed the water and were split down the middle in terms of color. so the red and green flower had one half red and the other half green. we found out that the process of a plant absorbing water is called cappilary action. cappilary tubes are like little straws that suck up he water and carry it throughout the plant. the tubes that hold the cappilaries are called xylems. The food coloring was absorbed with the water through the xylems and showed up in the pedals of the flower. So our experiment was successful.

This kid has an oval face, dark hair, and broad eyebrows. his dad is homozygous for his dark hair and broad eyebrows. the mom it homozyous for her oval face but hedorozygous for her blonde hair and thin eyebrows

My original question about bacteria in our school was if there's more bacteria on things that get cleaned often but touched often, or things that don't get touched often and very seldom cleaned. I swabbed the basketball, the water fountain nozzle, the microphone in the auditorium, and the door handle. It turns out the microphone has the most bacteria by far. There was one big colony of bacteria growing. The basketball had the next most, then the handle and the nozzle had little if any bacteria. I originally predicted the handle would have the most bacteria but now I know the things that don't get washed often are the dirtiest.

How do cells grow? Chromosomes duplicate themselves, then both of them move to opposite cell walls. The cell elongated and the plasma membran grows inward, then the cell splits. The cell divides and creates two sister cells which have everything they need from their mother cell.

These are the phases that take place when cells repair,grow,multiply,and divide.
1.Interphase: Cells may appear inactive during this stage, but they are quite the opposite. This is the longest period of the complete cell cycle during which DNA replicates, the centrioles divide, and proteins are actively produced.
2.Prophase: During this first mitotic stage, the nucleolus fades and chromatin (replicated DNA and associated proteins) condenses into chromosomes. Each replicated chromosome comprises two chromatids, both with the same genetic information. Microtubules of the cytoskeleton, responsible for cell shape, motility and attachment to other cells during interphase, disassemble. And the building blocks of these microtubules are used to grow the mitotic spindle from the region of the centrosomes.
3.Metaphase: Tension applied by the spindle fibers aligns all chromosomes in one plane at the center of the cell.
4.Anaphase: Spindle fibers shorten, the kinetochores separate, and the chromatids (daughter chromosomes) are pulled apart and begin moving to the cell poles.
5.Telophase: The daughter chromosomes arrive at the poles and the spindle fibers that have pulled them apart disappear.
6.Cytokinesis: The spindle fibers not attached to chromosomes begin breaking down until only that portion of overlap is left. It is in this region that a contractile ring cleaves the cell into two daughter cells. Microtubules then reorganize into a new cytoskeleton for the return to interphase.

The chromosomes split apart and create two cells inside one and then the cell splits to create two.
