To put the flies to sleep, first, two Drosophila Anesthetizers were obtained. One of the two sponge caps was soaked in ether (1 mL). Then, the glass vial containing Drosophila was gently and quickly tapped on the lab bench to temporarily disorient the flies. The cap was removed and a Drosophila Anesthetizer was placed on over the vial. The vial and the Anesthetizer were flipped over and tapped against the lab bench to disorient the flies again.…
Noah Haack 10/5 Biology 6 Hawaiian Hawk The Hawaiian Hawk is one of the very few native birds of prey left on the Hawaiian Islands, and the only native hawk to Hawaii. It has a medium brown color on it’s back, and a snow white belly. It is about 16-18 inches tall weighing about 1 pound.…
The Effect Of A Penny And Aspirin On Cut Flowers I. INTRODUCTION This report presents an experiment of trying to figure out what different variables make cut flowers survive longer. In this experiment I will be taking cut flowers and placing them into different plastic cups with different objects inside the cups. The objects are aspirin, a penny, and normal tap water. I know that putting a penny in the water causes oxygen to flow through the water into the flower.…
The Limulus polyphemus has a primitive blood. According to Bang & Levin (n.d.) the Atlantic horseshoe crab blood carries oxygen and has a special pigment that is a protein called hemocyanin. Homo sapien blood has a very similar protein in it called hemoglobin that makes the blood red from iron in the blood.…
ambient light is significant. However, there are only 8 trials for these results so these results are not as accurate as the data that comes from the all trials from all the classes put together, which were 197. From these results the null hypothesis is rejected the experimental hypothesis is supported since the p-value was 0.314, which is much more that 0.05. This proves that the difference in average metabolic rate of goldfish in dark versus ambient light is not significant. The whole class results from all trials gives a better idea about whether metabolism of goldfish is effected when in normal light or in the dark.…
Hydrocephalus is a medical condition in which there is cerebrospinal fluid in the brain. This cause increases pressure inside the skull and may cause enlargement of the head if it occurs in the childhood, it can cause convulsions, mental disability and tunnel vision. It can also be called “Water on the brain.” Hydrocephalus can be inherited or acquired factors. This includes Spina Bifida, Craniosynostosis and Vein of Galen malformations.…
We put the sowbugs in a clear, plastic box and then we set our light source, which was a lamp, different distances away from the box. Then, we observed the sowbugs and collected data. We concluded that the sowbugs get farther away from the light as the lamp is closer to them since we can see in the graph from Presentation of Processed Data that when the lamp was 10 centimeters away from the box, the sowbugs got the farthest…
Its whiskers are highly sensitive to touch and help them navigate in the dark. Their ears can hear extremely quiet sounds to extremely high pitch sound which helps them hear there prey around…
Large quantity of agnostid fossils were discovered in areas around the world. However, limited information provided by these fossil fail to determine how these agnostid lived 450 million years ago. Three theories are proposed but are all disputed by the professor. First, the reading passage claims that the primitive arthropod acted like free-swimming predators.…
One of the key matters to be addressed in comparing Neanderthals to H. sapiens lies in assessing the intelligence of the former. Paleoanthropologists have long sought clues to Neanderthal cognition in the fossilized skulls they left behind. By studying casts of the interior of the braincase, known as endocasts, researchers can recreate the external form of an extinct brain, which reveals the overall size as well as the shape of certain of its regions. But those analyses have failed to render much evidence in regard to distinct differences between Neanderthal brains and those of H. sapiens. While Neanderthal brains were a little flatter than those of H. sapiens, they were just as large, indeed, in many cases they were larger.…
Pill Bugs: An experiment Introduction Pill bugs are very small and can be found anywhere. Under rocks, in between cracks, in your science class; they are everywhere! However, it is common knowledge that pill bugs do not like to be in open spaces. There are just too many dangerous possibilities, and they don’t need to take the risks. In this experiment, we tested to see if light affected the decisions of where pill bugs like to stay.…
The purpose of this paper is to evaluate the correlational method as a means for examining the relationship between functions of the left and right hemispheres. I will compare the performance of people with intact brains with the performance of so-called split-brain patients. In many ways, the brains of these two groups are very similar. 1 a. For example, the brainstem exists at the base of the brain connecting the brain and spinal cord and has no functional differences between an intact and split brain patient.…
Pollinators, flowers, and their relationship play an essential role in ecosystems. Pollinators are responsible for facilitating fertilization in flowering plants, which provides seed production in fruits and vegetables. Pollination is important in agricultural communities with the fertilization of crops. It is estimated that pollinators contribute to the global economy by adding 217 billion dollars from pollinating a vast array of crops (Gallai et al., 2009). The pollinator-flower relationship also helps in water filtration, flood and erosion management, wildlife support, and carbon sequestration (Pharo and Daily, 1998).…
The English Peppered Moth and Natural Selection Lab By: Justin Pascual Partners: Nathan Magbitang, Rudy Keyes-Krysakowski, and Glenn Tipold Teacher: Ms. Coopman Date Performed: November 16, 2015 The English Peppered Moth and Natural Selection Lab Purpose The purpose of this lab is to determine how variation in a population can favour survival of a certain trait over multiple generations. Hypothesis It is believed that if there are more speckled moths remaining in the tray at the end of the experiment, it will represent the fact that the conditions of the surrounding environment have favoured their colour.…
We are incapable to precisely conceive the idea of being a bat. We can point out the physical aspects of bat life, but we cannot point out the bat experience. According to Nagel, the conscious experience can occur at many levels of animal life. However, there is no evidence to provide assurance that it is present in simpler organisms [i.e bats] (436). If an organism experience and/or feel pain then that organism have a conscious.…
