...The experience of the egg drop project was one that will help you realize that not every way that you try will work, and just because you fail once doesn't mean you can't try again. I believe my egg broke possibly because when I was testing mine I was working with a larger egg. So when it came to the drop it wasn't supported by the walls as much as it should have been. I believe also because the straws on the bottom didn't really reach the egg since it was a smaller egg than what I was practicing with. I feel if I had also dropped it a couple more times or had made it a tiny bit smaller it might have concealed the egg better , and hopefully wouldn't have cracked than.I believe also that when it came to the test it didn't land straight on...

...The Egg Drop project consisted of a few different materials that lessened the egg’s force of impact on the earth. The materials used were: two toilet paper rolls, nine and a half straws, and a half piece of printer paper. Other materials used were: very strong glue and masking tape to hold the contraption together. The egg never touched the ground, which lessened the force on it. Instead of the egg receiving the maximum force of the cement, the materials around it did. The outside materials were very important for this project to be successful because they were much stronger, and provided a lot more support than the egg alone. The main feature of the container that lessened the force when it came in contact with the earth...

...Madelyn Lashinis Term Paper Article Summary Sexual Selection: Pipefish In this research, they looked at many observations that took place with sexual selection in pipefish. They looked into how and where breeding took place, how long the cycle of sexual selection took, and how fast the pipefish grew. The researchers used different waters (Portugal and Ireland) and the different temperatures of waters. That way it gave them more information to learn and choose from. Their hypothesis stated that the southern pipefish population would sense warm water and a longer breeding time, across a milder pressure of selection, with fewer females. The researches had predicted that the fish living farther north are where the males will be necessary, that...

...illustrate some hypotheses. This paper reviews the research conducted on orang-utans/pinworm associations and critically evaluates its successes and failures. Extraction methods Firstly is best to address how pinworms are extracted. Extraction provides identification and quantities of nematodes for use in population studies, leading to dependable approximations of age-structure and sex proportions (Ferris, 1987). Several methods exist, i) the Baermann wet funnel; ii) decanting and filtering techniques; iii) Flotation by a continuous torrent of water (Schouten and Arp 1991). Each extraction method suffers from nematode losses (trapped on sieve, funnel wall). The Baerman funnel has one of the highest extraction success (Son and Moon 2012) with as high as 80%, making this method highly practical. Nevertheless since this method relies on nematode migration it can be affected by temperature (lessening its efficiency). Though under controlled laboratory surroundings temperature extremes should not present a problem. Another way to obtain pinworm eggs is to place adhesive tape around the perianal area. The tape can be then placed onto a microscopic slide for authentication. Additionally faecal nematodes can be analysed by using an agar plate for isolation and a successive examination (hatching test) to determine the viability of eggs (Garcia 2009). Mode of infection and symptoms Of the genus Enterobius transmission occurs primarily when the infective larvae (eggs) are ingestion (Cook 1994)...

Red onion extract was the substance tested. The experiment was done by first determining whether the solutions muriatic acid, bleach and red onion extract are acidic, basic or neutral by dropping a substance of each solution in a pH paper. The pH paper turned purple red for muriatic acid (pH level of 1 according to the pH wheel), olive green for bleach (pH level of 9) and yellow for red onion extract...

...In Greenberg’s paper, he analyzes gender and compares the survival values of sucrose and water, and finds that flies live about 50 percent longer on sucrose alone than on water alone, and that female house flies live more than 35 percent longer than male house flies (Greenberg 1960). In Chapman et. al's paper, a study evaluated food odours and female house fly sex pheromones which were applied to a sugar mixture to gauge the attraction potential of such variables (Chapman et al. 1998). Brown’s study concentrated on the development of chemical attractants as bait, and found that none of his compounds were active enough to attractive flies on a per-compound basis but that a combination of a few compounds were successful in attracting flies (Brown...

...cell researcher who rose to fame however soon it was known that the data was fabricated and the papers were retracted.The general public wasnt affected by it however it does involve and time and money to replicate such results and which is never acheived. So it actually a fraud or a human error, the only difference between a fraud and an error is intention. It could be argued that is there any room for scientists to make errors and yes we all are capable of making errors, they can make errors too however they have the chance to correct such errors before publishing such data instead such papers do see the light of the day, a lot is dependent on these scientific researchers then why is the data tampered and results are achieved per the own needs, a research shouldn’t driven as per the needs of an individual or for any sector [1]. It is based on any actual data which may eventually lead to saving lives or aiming for a better world or better resources or a better environment. Driving factors for scientific frauds Science is a result driven discipline, a ‘Publish or Perish ‘environment which is like the survival of the fittest, where everything is data in facts, figures and tables. It could be an increase in competition to stand out, to publish the best journals, research which atleast looks like a breakthrough and the rewards associated with this are also high as compared to the research budgets [2].

...Plankton Depletion and Environmental Effects Plankton is a term generally used for microorganisms or “floaters” that simply drift along wherever water currents take them. This includes zooplankton, algae, phytoplankton, and bacteria (G. Karleskint Jr. et al, 2010, p.464). But while it is common to see them as food for fish, they have other roles in nature what make them essential organisms in the delicate balance of our ecosystem. This paper will highlight the critical role of plankton as the organisms that make life on earth possible by describing the foundational role it plays in the food chain and in significant bio-chemical processes and discussing the negative effects it will give to the environment. I. Main Functions of Plankton in the Environment There are two main roles played by plankton in the environment. The first important role of plankton is in the food chain. Because of their microscopic size, they serve as food for other microorganisms, fishes and seal animals, which make-up 30% percent of the world’s entire intake of animal protein (J.H. Steele et al, 2009, p.8). Thus, we find plankton at the bottom of the food chain: zooplanktons eat other planktons for food, which in turn, along with phytoplankton and bacterioplankton, are food for fish and sea mammals, most of which eventually become food for human beings. Secondly, plankton plays an important role in the earth’s biochemical processes. Phytoplankton, for one, is responsible for the primary production...

...Rebuttal Paper Dayna Kielau BCOM/275 January 16, 2012 Plan B One Step is an emergency contraceptive pill that prevents the fertilization of an egg after unprotected sex. The FDA wanted Plan B One Step to be made available without a prescription to all ages. The Health and Human Services Secretary Kathleen Sebelius overruled this. “The result of Sebelius' action is that Plan B will remain available to women ages 17 and older without a prescription, but those 16 and younger will still need to see a doctor first in order to get the product.” (www.npr.org) The decision was also backed up by President Obama. In a news conference Obama stated “I will say this, as the father of two daughters. I think it is important for us to make sure that we apply some common sense to various rules when it comes to over-the-counter medicine. And as I understand it, the reason Kathleen made this decision was she could not be confident that a 10-year old or an 11-year old goes into a drugstore, should be able – alongside bubble gum or batteries – be able to buy a medication that potentially, if not used properly, could end up having an adverse effect. And I think most parents would probably feel the same way.” (www.npr.org) “As doctors and researchers have repeatedly stated, ample research shows Plan B to be safe for women of all ages and appropriate for over-the-counter access. It is deeply disappointing that this administration would repeat the mistakes of the previous one,”...

...resolution is a measure of where the neural activity, with precision, is located. So how good is the graphic display or how well is the image. (B) EGG is a really good measure of timing; it can pick up when the electrical impulses happen relatively quickly. It is related as the best temporal resolution measure from all the tools; however, it is a poor measure of mentioning where the impulses happen. It is ranked as the worst from all the three in terms of spatial resolution. FMRI is the best measure in term of spatial resolution. It can detect a spatial range from mm to cm. In terms of temporal it is the second best, it can detect neural activity within almost two seconds and with technological improvements it is getting faster and faster. (C) FRMI would be better to measure the brain activation in the limbic system. FMRI essentially uses the same technology as the MRI but it more function. Brain activity can be measure through the blood flow. FMRI tells us essentially tells us what is happening in out brain while we are making our decisions. It will have a good read on where and when those signals are happening. However, despite that FMRI requires repeated sampling to account for noise such as heart beats, breathing and other factors it is very accurate in predicting ones emotions. Question 2.
