Grab two dissecting pins and place them one on each end of the earthworm. After the earthworm is well placed in the tray, grab the scalpel and start opening the worm carefully, do not press too much because then the intestines will open too. Once it’s fully opened, we will use the dissecting pins and the dissecting probe. With the dissecting probe we keep on opening the body to fully see the earthworm from the inside. Grab the pin and place them one on each side, as much as you want to see the whole earthworm’s insides.
Also, these worms are invertebrates, meaning they possess no vertebral column/backbone. Furthermore, planarians, as well as earthworms are scavengers, a type of decomposer. Planarians eat dead or decaying material, and earthworms eat soil, rotting leaves, and other organic material. Additionally, without our lovely decomposer friends, our world will become a huge dump, which again is an advantage. Lastly, if you haven’t noticed, the long cylindrical and no legged animals are part of the enormous worm family!
Mitosis In this experiment, I learned to make my own cheek cell slide to view under the microscope, and I also viewed fish cells under the microscope The purpose of this was to become familiar with a microscope and it's features, as well as, find and identify cells and the stages of mitosis. In doing so, I was able to differentiate between the different stages of mitosis from Interphase to Telophase. Materials: 1 Microscope 1 slide 1 slide cover 1 drop blue dye 1 tooth pick 1 slide with fish cells 1 camera phone 1 pen 1 piece of paper (in lab manual) Method: Cheek Cells First I took a toothpick and swabbed the inside of my cheek for a few moments. I then rubbed the toothpick on the slide, put one drop of blue dye on top of the slide, then covered the saliva/dye mixture with the slide cover. After that, I placed the slide under the microscope and began searching for the cells that were on the slide.
In the book it says,“Most parasites live in more than one kind of animal, but they’re all trying to reach their final host, the ultimate vector”(60). Parasites can kill their host but once their host is dead they die along with it in Peeps it says,“One thing about parasites—they’re great at living inside other organisms, but once they hit the outside world, they’re not so tough.”(109) In some ways the parasite situation form the book could be true only some aspects could. The unusual strength, night vision, heightened senses, and an affinity with rats cannot be a realistic benefit form a sexual transmitted parasite. Parasites
Baby garter snakes shed their first skin almost immediately, and will begin eating soon after. Garter snakes just require a 10 gallon (38 liter) terrarium. The first shedding is very fine and often disintegrates in minutes under the slithering masses of new snakes. Feeding baby garter snakes can be tricky; earth worms (not compost worms), night crawlers (called dew worms in Canada), silversides (fish), or cut up pieces of pinky mice (thawed fully and waved before the snake on a pair of tongs or hemostats to avoid nipping fingers) will entice appetites.

The case described benefits of the new drug as a low-cost, safe, and simple cure for river blindness. The current residents suffering from this parasite did not have funds to afford alternate treatments like expensive hospital visits or other drug options that are required for a cure. As reported in the reading, the condition is caused by a worm that is passed through the bite of a black fly along the tropical areas of Africa and Latin America. The worm then burrows under the skin and continues to grow up to a length of two feet. As the worm reproduces, it releases millions of offspring that slowly wriggle underneath the skin until invading the eyes, eventually causing blindness.
They replicate by invading targeted cells of their host and taking over genetic material responsible for reproduction. These are tiny infectious agents that are so small that even a light microscope will not detect them visibly, infecting all kinds of cells from bacteria, fungi, plants, animals and humans. Some of their common illnesses and infections include colds, influenza, chicken pox, measles, mumps, herpes, norovirus and cold sores. Fungi are simple plant like single-celled organisms, reproducing both sexually and asexually via spores. They take on various forms and can include yeast and moulds.
Samantha VanderVeen Mrs. Flegel AP Biology 10 September 2012 Environmental Effects on Isopods In this lab, there was testing of three different environment variables that could affect the lifestyle of an isopod. We used household items such as makeshift tin foil containers, strawberries and potatoes, wet paper towel, a lamp and piece of brown cardstock, along with about 50 isopods to participate in this experiment. Allowing us to determine what kind of environment isopods prefer. We were able to conclude that isopods prefer a dark, damp atmosphere with a large supply of a starchy food source. As a whole, the class was asked to create and carry out at least three environmental differences that would help create and single out variables to help find the most desirable environment for the isopods.
Introduction: Using garlic to kill bacteria both externally and internally is a natural answer to the problem of ingesting the drugs and toxins contained in other products. Body Paragraph 1: Bacteria Bacteria are very tiny microscopic organisms that are unicellular which means they are made up of a single cell. They are the smallest and simplest organisms on earth. Bacteria also come in a variety of shapes and sizes, and their size is measured in micrometer which is a millionth of a meter. Bacteria are found everywhere in the world in all types of environment.
The Native American Indians had many different views on how the world was made, which they called creation legends. In “How the World Was Made” all the animals were above and crowded in Galunlati. They wanted more room so they sent Dayunisi, the little water beetle, to see if he could learn anything. He could not find a place to rest: “Then it dived to the bottom and came up with some soft mud, which began to spread on every side until it became the island which we call the earth” (Cherokee 48). For some time after the earth was flat, soft, and wet.
