Dissection lab In the past 3 weeks we have been dissecting animals of all different sorts. We dissected a worm‚ crayfish‚ grasshopper‚ and a perch (fish). In my conclusion I will explain the diet‚ habitat‚ and how these relate to the structure of these animals. First I am going to be talking about the worm. The Earthworms have setae in groups around or under their body. The setae‚ paired in groups on each segment‚ can be moved in and out to grip the ground or the walls of a burrow. Worms travel

Sahara Desert The Sahara Desert is the world’s largest desert area. The word Sahara comes from the Arabic word sahra’‚ meaning desert. It extends from the Africa’s Atlantic Ocean side to the Red Sea and consists of the countries of Morocco‚ Algeria‚ Tunisia‚ Libya‚ Egypt‚ Mauritania‚ Mali‚ Niger‚ Chad‚ and Sudan. It is about 5‚200 miles long. Overall‚ the Sahara Desert covers 3‚500‚000 square miles. The geography of the desert is varied. In the west‚ the Sahara is rocky with varied elevation

Bali (3). Surprisingly‚ the octopi have been viewed during the daylight hours‚ generally residing near sand tunnels‚ and holes (1). The octopi enjoy these mounds because they provide a significant source of food‚ including small worms‚ fish‚ and crustaceans. The octopus utilizes its arms to feel for prey‚ and then captures the food through the use of expanded webs. However‚ when the animal is attempting to hide itself from possible enemies‚ the Indo-Malayan octopus can transform itself into a variety

Ellen Ryan Biology IA Task G1 Investigation into the biodiversity of organisms at different heights on a rocky shore. PART (1) Ellen Ryan Introduction This experiment was carried out in order to better understand Hong Kong’s ecology and biodiversity‚ specifically focusing on field-based whole organism biology in an area with little human interferences. Method 1. Lay a horizontal transect on the mid-shore (1.75m) 2. Repeat for high-shore (2.25m) 3. At regular intervals of 1m

this experiment I aim to find out if caffeine has an affect on heart rate. Instead of using human subject‚ whom may already have a high tolerance to caffeine or could have ingested caffeine that day making the tests unfair‚ I will use Daphnia‚ a crustacean. They have on contact with caffeine making it fair. It will be easier to observe as it has a translucent body‚ making it able to see the heart beating under a microscope. It will be a "blind study" to avoid bias results‚ so everyone will be unaware

Organ Systems Project (Digestive‚ Excretory‚ Circulatory‚ Reproductive‚ Nervous) There is an enormous variety of life on our planet Earth ranging from simple cell bacteria to complex multicellular animals. Animals are creatures in the kingdom Animilia‚ one of the kingdoms in Whitakers 5 kingdom system. Their bodies consist of 555tanimal eukaryotic cells. Meaning their cell or cells contain a nucleus‚ are surrounded by a cell membrane (phospholipid bilayer) and can self-reproduce in a free

"Nature and the Environment" "Ecology or the study of nature and the environment involves us in the conservation of the earth. We are at a point in the history of civilization where awareness of our fragile relationship to nature and the environment is high. We are losing 3‚000 acres of rain forest around the world and four species of plants and animals. More plants‚ insects‚ birds and animals became extinct in the 20th century than in any era since the Cretaceous catastrophe more than 65 million

and swelling. One of the leading drugs on the market today is Ibuprofen which you may know as Motrin or Advil. Both drugs are identical except for quantity and price‚ and even there it might be the same. The organism I chose to work with is a crustacean called the Daphnia. Later in this report I will attempt to explain the significance of that organism and why I chose to conduct tests on it. I then‚ with the information at my disposal‚ conjured a hypothesis which I would test. Using the materials

Megan Williamson period: 3 4/29/13 Objectives: The purpose of this lab was to study and observe the organs in a crayfish and be able to name them. Introduction: Crayfish belong to the kingdom animilia‚ phylum arthropod and class crustaceans. The body is divided into three parts‚ the body‚ the head‚ thorax‚ and abdomen. The head and thorax are apart of a segment called cephalothoraxes‚ which is covered by the carapace made of chitin. The exoskeleton covers the outer body of the ventral

humans ingest chemicals from synthetics which aquatic animals previously consumed. As plastic remains in the oceans it will continually find a path up the food chain‚ consequently humans will inescapably ingest their own trash through fish and crustaceans which occupy large portions of daily diets. Consumers also avoid the most detrimental aspect of ocean dumping‚ the result it has on phytoplankton‚ microscopic organisms that account for virtually 50% of oxygen. By blindly consuming and creating
