Explain what Tutankhamun’s tomb reveals about ancient Egyptian daily life and beliefs The discovery of Tutankhamun’s tomb by Howard Carter with the help of Lord Carnarvon in September 1922 provides a great insight into ancient Egyptian daily life and after life beliefs. Tutankhamun’s tomb includes four rooms; the annex‚ treasury‚ antechamber and burial chamber. The artifacts in each of these chambers reveal information about the funeral proceedings‚ the role of the pharaoh‚ foreign influences‚ religion

occurred during the experiment was that some flies became stuck in the food source and died. The main cause of this was the fact that the fly vials were stood up (vertically) before the flies had fully recovered from the anaesthetic. This could be overcome in future experiments by ensuring that the vials are kept horizontal until all of the flies fully recover from the anaesthetic. One possible error that may have occurred was that some of the adult flies may have accidentally been left in the vials

frog moth butterfly Grass Discussion In the pratical numerous organisms were detected; most of these organisms could be said to have 4 to eight legs. It is evident that some could fly and some could not ly. The trophic levels ranged from one to four; while the auto-troph was a tamarind tree and some grass. The herbivore was a butterfly which fed entirely on the tamarind tree. Also‚ a carnivore which fed on more than one

purposes. The mitochondrial matrix receives pyruvate from the cytoplasm after it crosses over the mitochondrial membrane. When the pyruvate enters the Krebs cycle it goes through many stages of biochemical enzyme-catalyzed reactions. In more detail about the cycle its main purpose is to produce little amounts of ATP by removing carbon dioxide and hydrogen from pyruvate molecules. Within the inner membrane of the mitochondrion the electron transport chain and chemiosmosis synthesis ATP with hydrogen

observe the selected four invertebrates and familiarize ourselves with their taxonomic levels through the organism’s mechanisms of feeding‚ motility‚ and reproduction. Our group used the prior knowledge we possessed about the Hydra‚ Rotifer‚ Gammarus‚ and Planaria organisms to complete the lab. We knew that all of these small invertebrates have a freshwater habitat. Each organism differs in taxonomic levels from Genus to Species. We knew that the Hydra reproduces with one of two methods: 1) by “budding”

Period 1 10/14/12 Enzyme lab Enzymes are biological catalysts that speed up the process of chemical reactions. They are also proteins‚ and most enzymes activities occur within organism. They decrease activation energy‚ energy that is needed to start a chemical reaction. Enzymes are substrate specific substrates ending in "-ase"‚ enzymes ending in "-ase". External factors‚ such as temperature‚ pH‚ and concentration of the substrate‚ affect the enzymes activity in the lab‚ pectase and cellulase will

Though‚ the 4th is VERY interesting. 1. What was Lamarck’s big idea? What a person does in their lifetime could be directly passed to their kids. 2. What human example did Lamarck use? A blacksmith‚ because they swing hammers all day they get muscles and those muscles pass down to their kids. 3.

What are probable sources of acid precipitation in your community? What impact can this have on the environment in your region? Some of the probable sources of acid precipitation is Fog‚ and rain. During the summer it hardly rains which makes it hard for our crops to grow‚ also since we are in the valley it makes it hard for us to get the water that we need. During the fall it gets very foggy in the mornings and it makes it very difficult to see while your driving. Prevailing winds can also
