Mariella Hines is a 9 year-old African-American girl attending the 3rd grade in the JFK School. She was referred to the School Psychologist because she has recently become very withdrawn during class, refusing to speak to anyone, including her teacher and peers. Previously she seemed to have age-appropriate social skills, interacting well at school. Her withdrawal started suddenly. Mariella’s teacher, Mrs. Levine, called Mariella’s mother to find out more information, but her mother said that Mariella seems fine at home.…
The dry wallum is a harsh environment that is battered by the sun and wind every day and with a base of porous sand; water availability is very scarce and must be conserved. The abiotic factors in the dry wallum are that the area is exposed to high amounts of sunlight which causes a loss of water in the leaves through transpiration. Since the wallum is so dry and hot; bush fires play a major cycle in the dry wallum which the trees have adapted to cope with. The roots of the plant and tree species have to cope with the leeching of nutrients because of the high porosity sand in the dry wallum.…

Yes there was a change because with the starting snail population there was a great variation from 1-7. After the crab began eating only the snails with the thickest shells survived. The snails with the thinnest shells were eaten by the crab. Only snails with shell thickness 4-7 were left after the crab had their meal. The original snails with thickness 1-3 were eliminated from the population by the crab. The crab will usually try to expend as little enrgy as it can to maximaize its happiness so the snails with thinner shells will likely be targeted first and eventually eliminated.…

1. Read the press release on the 2001 Nobel Prize. Summarize in a few paragraphs the accomplishments of these scientists, and the relevance of their discoveries. (Answer in 500 words or less. Send to instructor)…
The focus of this experiment was to identify unknown bacteria provided. The identification of unknown bacteria is beneficial in many aspects of the research of microorganisms and also aids physicians to treat patients correctly. Various tests were performed to provide the fermentation abilities, presence of particular enzymes, and biochemical reactions. Qualitative observations were made on the tests in identification process. The data from experimentation provided sufficient results to suggest that the identity of unknown bacterium was the gram-positive spore forming bacteria, Bacillus Subtilis.…
“Huntington’s disease was both concisely and succinctly described as a specific disease entity in 1872 by George Huntington” (HuntingtonsDisease 1). George Huntington decided he was going to publish his finding to classify it as a disease. “Several reports before 1872 describe movement that later authors attribute to…

I was used to wake up, smash my alarm clock until it was dead silent, slither out of my cozy sheets and jump out of the shower when the water was freezing cold without considering the neural activity that precipitated my habitual movements. Having a close relative die due to a genetic disease puts everything into question. Since my grandfathers passing, I have started to take better care of myself. I know that bad things are going to happen, but I have the power to prevent some of those things from occurring. I have made my decision to get tested when I turn 21. I have considered the pros and cons. Getting to this point was not easy primarily because my mother refuses to get tested. Revealing my tested HD statues also reveals whether or not my mom carries the gene. No one wants to know their expiration date, let alone know how they will die. When I was born she didn't know there was a possibility of me acquiring a progressive, degenerative brain disorder. I owe it my future children to be responsible and determine if I have been passed down this cruel…
