Mealworm Lab Report

If a sow bug is placed in a choice tray, and has access to decaying leaves, potatoes, grapes, and sow bug food, the sow bug will choose the decaying leaves over its other options. This hypothesis was based on research stating that a sow bug's main food source is decaying vegetation. This is the food they are accustomed to and therefore will select over the other three options which they rarely if ever would have access to.

Once upon a time in a lab far far away there was a very curious young scientist named James. James is a very young man who one day stumbled upon a new subject flatworms. He found early in his research that they can be very dangerous but on the other hand can help the earth. When he went into his lab early one morning he discovered that the worm had many segments so he tried an experiment if on piece of flatworm can regenerate into an entirely new form of flatworm. His experiment was a smashing success. He was a very known scientist all around his house. He was very excited and had just found a groundbreaking discovery for flatworms.

The hypothesis that was tested was pill bugs are use to the cooler temperature of the room and natural soil would travel a greater distance once they were in a hotter environment. The hypothesis is rejected on the basis that the p-value of .760 is greater than .05. Furthermore, figure 3 supports this rejection, since the averages are very close to each other and their error bars completely overlap. This rejection means that once the pill bugs where in the hotter environment there was not difference in their behavior compared to the cooler room temperature environment; they did not travel longer distances. However looking at bugs D, F G and H in figure 2, there is a difference in distance traveled that appears to be greater than

In this experiment, contractions of the earthworm gut are measured in an organ bath with a force transducer. The effect of neurotransmitters and ionic concentrations on contraction strength and rate will be investigated.

The purpose of this lab was to save a little gummy worm named Sam from drowning. In addition, one of the labs key terms was a hypothesis which is a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation. Furthermore, we also learned that an independent variable is a factor that is changed during the experiment. On the other hand, the dependent variable is the factor that is observed or measured during the experiment. To begin with, the experiment the hypothesis formulated was if we reshape the paperclips into hooks and pick up sam, and the lifesaver (without touching them), then the lifesaver would be stretched enough for Sam to go through it.

Citrobacter Freundii is a species of bacteria that can be potentially harmful to humans. It is known to cause meningitis by protruding into the brain and replicating itself (1). The Citrobacter species has also been found as a cause of some urinary tract infections, diarrhea, and even gastrointestinal diseases and symptoms (3). C. Freundii can be located in a wide variety of soils and water (3). Lastly, it is also the cause of many nosocomial infections due to its presence in water (1).

Just last month, a deadly worm was found in not one, but four locations in the U.S. state of Florida. This worm, until recently, was documented in only twenty-one countries, most of which were island nations. Although the New Guinea Flatworm may seem as a highly dangerous predator, it is only about two inches in length and mainly targets snails for its nutrition. These worms are not harmful to humans, but they will feast on any soft creature in the soil. In order to eat snails or any critters with a hard shell, the New Guinea Flatworm latches itself onto the shell’s opening and then spits out its own stomach through the opening in its belly. This allows an acidic goo to dissolve the snail’s flesh and the worm can continue on with its meal by swallowing both its stomach and the snail.

I love gummy worms I been in a gummy worm factory I fell in love with it just the flavors and sweet texture just grab my attention not in that way. I use to buy gummy bears a lot everyday I had a little bit of a sweet tooth my mom just always buy me some gummies at dollar the store. It's kinda funny how i just always on my birthday my mom would ask me what i want for my birthday I would just say money and gummy worms. My mom would just be cool with it she really didn't even care she wasn't buying expensive things that's why.

In each experiment , the pillbugs showed taxis. We observed how pillbugs incline toward dark and warm environments. There was a major distinction when the pill bugs picked between the dark and warm condition, 48 pill bugs went to the dark condition and 12 went to the light condition. By utilizing the chi-squared analysis, the calculated value ended up being 9.6 for the light and dark condition. This value was more prominent than the critical value of a 3.84. This implies the null hypothesis rejected in light of the fact that there is no contrast between these two conditions.When it came picking between the warm or cold condition there was a major distinction , 42 went to the cold condition and 18 went to the warm side. By utilizing the chi-squared

For this lab 6 male Acheta domesticus were isolated in plastic containers, each was placed in a container that was 5 cm height and had 5.5 cm radius. Each of these containers was punctured with 10-15 minuscule holes for breathing on the lid and 5-8 holes on the sides. Inside of each container a damp paper towel was placed on the bottom and 2 pieces of food were placed on the paper towel. The Acheta domesticus were kept isolated in their personal containers for 7 days. At the end of these 7 days we split the 6 A. domesticus into 3 groups of 2. One of the two was marked with a paint pen, this marked male was the “intruder”. The remaining food was removed from the containers. The “intruder” is then placed into the container that holds the other

Hypothesis: Mealworms will prefer darker environments over lighter environments because they live underground their eyes(if they have any) will be very sensitive to the light.

Military worms can also be used for reconnaissance. In, 2012, shortly after Stuxnet, the Russians discovered a virus, later named Flame, which had been extracting and dumping all data from Russian computers. The article, “Flame: Massive cyber-attack discovered, researchers say” by Dave Lee explains, “Once a system is infected, Flame begins a complex set of operations, including sniffing the network traffic, taking screenshots, recording audio conversations, intercepting the keyboard, and so on” (Lee). This usage of computer worms demonstrates the versatility of cyberwarfare. Not only can computer worms target specific factories and agencies, they can also be used to collect data secretly from other countries. In this passage, the author says Flame has been “ taking screenshots, recording audio conversations, [and] intercepting the keyboard.” Imagine if the U.S. was attacked by Flame. The virus could have been recording all search history, what individuals look like, and what they have said around their computer for months, while it sends all of this information to another country. This gives some insight into how powerful cyber weapons can be. The have the power to stalk anyone, almost anywhere, while remaining almost completely undetected. Later in the document, David Lee writes, “Whereas Stuxnet just had one purpose in life, Flame is a toolkit, so they can go after just about everything they can get their hands on. Once the initial Flame malware has infected a machine,

Life on this planet began with microorganisms. Through millions of years microorganisms have found ways to successfully adapt and survive. These adaptations have created a wide biodiversity, allowing them to basically populate in all places. Why are these microbes so important? Because they shape the history of our world. Some microbes can be deathly to humans while some others are favorable, for example, bacteria that lives in the gut of both humans and animals and helps during the process of digestion (Alfred Brown & Heidi Smith, 2006). Understanding these interactions help scientists to find ways to protect humans from potential deathly pathogens. In order to observe microbes, microscope proficiency and microorganisms’ identification are crucial skills in a microbiology lab. During this laboratory session, samples of environmental and human organisms were inoculated into two different rich media and incubated to their according temperature. After this, appropriate use and calibration of the microscope was performed. Lastly, morphology and size of different species of bacteria, algae, fungi and protozoan were recorded.

The purpose of this experiment is to test how location affects whether or not the clay caterpillar models will get pecked by birds. Twenty-one clay caterpillars were made and they were made to be 5 cm ± 0.01cm long and 1 cm ± 0.01cm in diameter. Seven caterpillar models were placed in each of the three locations. The three locations are my backyard, the park, and my community garden. As a control variable, all the caterpillars were placed 300 cm ± 50 cm above the ground. An equal amount of caterpillars were glued, to prevent them falling off, in similar areas such as trees, bushes, and fences. This experiment went on for three weeks. Each week is considered one trial. Each caterpillar that was pecked or not was recorded and the data was placed

In order to identify what food, and ultimately from which restaurant Parry ate the day of his poisoning, four experiments were carried out. Each experiment tested for the presence of the following four macromolecules in Parry’s vomit:
