(A)Adult worms in meninges lay eggs (B) eggs go into circulation, reaches the lungs (C) hatches into larvae L1. The L1 migrate up bronchial tree (D) to pharynx, coughed, swallowed, feces (E). L1 infects snails or slug through foot. L3 takes approximately 3 weeks. F-S with L3 are ingested penetrates abomasum, spinal nerves to spinal cord. Mature 20-30 days to adults. Adults migrate to subdural space to brain from ingestion to exit of eggs in feces (prepatent period).…
The aim of this experiment is to see which brand of paper towel absorbs the most water out of a 200mL beaker.…
The rate of respiration in mealworms from the twelve experimental tubes in the light treatment ranged from 0.0489 mL O2/g/hr to 1.1611 mL O2/g/hr. The average rate of respiration was determined to be 0.4034 ± 0.1886 mL O2/g/hr. The rate of respiration in mealworms from the six control tubes of light treatment ranged from 0 mL O2/g/hr to 0.0859 mL O2/g/hr. The average rate of respiration of them was determined to be 0.0208 ± 0.0068 mL O2/g/hr. The CI bars of the experimental tubes and the control tubes in this treatment did not overlap, so they were determined to be significantly different from each other.…
My results to my findings to my brine shrimp experiment was started on 12-28-15, using 4 jars. Each jar contained water, salt, and brine shrimp eggs. I started by filling each jar with tap water and then adding salt. I added 1 TSP of salt and each jar added ½ TSP more of salt. In my experiment I noticed on the first day, 12-28-15, in all the jars the brine shrimp eggs were added to the 4 jars. Some observations I noticed were the eggs didn’t sink right away, they stayed on the surface for awhile. On the second day, 12-29-15, in jar 1 85% of the brine shrimp eggs hatched. In jar 2 75% of the brine shrimp eggs hatched. In jar 3 65% of the brine shrimp eggs hatched, and in jar 4 70% of the brine shrimp eggs hatched. All 4 of the jars had the same observations, they didn’t swim gracefully, they were on the side of the jar with more light, and there was still unhatched…
All three worms were cut in half. We had expected all the planarians to regenerate. The prediction made was the planarian that was the longest, would regenerate the quickest and begin to behave normally first.…
11. Drag the response that corresponds to the mealworm’s actual behavior to the Actual Behavior area. Record the Actual Behavior in the table on the next page.…
-One fungus makes traps for nematode worms while another fungus has sticky knobs to hold them in place while hyphae penetrate into nematode worm’s body with digestive enzyme and extracellular digestion takes place.…
The experiment was to test which the pill bugs preferred, a moist surface or a dry surface. We took twenty random pill bugs and divided them into individual groups of five. We then placed the four groups into isolated bare arena compartments and they were left to acclimate to the environment for ten…
In the beginning of The Cheese and the Worms, the readers are introduced to a miller named Domenico Scandella, who the narrator refers to as Menocchio. It was uncertain where Menocchio retained his knowledge, but it is obvious that he picked up learning how to read somewhere. No one knows for sure, but it is assumed that there was a school built near Menocchio’s village. It may have been possible for Menocchio to attend this school and have the opportunity to learn to read books, like the bible. Menocchio was a miller, was married and had eleven children. He also was the mayor of his village.…
This result corresponded to the prediction made before the experiment was conducted. The amphipod feeding preference is probably due to the Norway leaves’ softer texture. Amphipods are capable of chewing on the soft tissue between leaf veins however, as seen with the data collected amphipods seem to favor softer leaf species because amphipods are able to consume softer with much less effort. By favoring the softer Norway leaves, amphipods are able to convert the coarse particulate organic matter into fine particulate matter much easier than the Silver leaves. This means that softer leaves would offer much more fine leaf particulate matter, which would in turn provide more nutrients and energy sources to lower level feeders in comparison to tougher…
While doing research on how to best design my paper towel experiment, I came across two other experiments that were relevant to mine. The first was a diaper absorbency experiment conducted by Vanessa W. in 1999 to determine which brand of diaper was the most absorbent. She used the same concept I will be using in my experiment by using water to test absorbency and measuring the amount of water left after each test. The second was a paper towel absorbency experiment conducted by Samantha P. in 2000. This experiment is very similar to the one I will be conducting, except she used a different measuring tool and method than I will be.…
Cheese and the Worms shows religious conflicts in the sixteenth-century through the court records of a small town miller who used different books to come up with his own view on religion. The fact that a man from a small town with very little education could use his very limited resources to become a target of the Catholic Church shows how much the Church was fighting to hold onto its power and influence. The book draws its information from the inquisition court records, which included the testimony of Menocchio’s fellow villagers and his own interactions with the inquisitors.…
Two different organisms that Darwin studied were finches and earthworms. Charles Darwin tested earthworms behaviour, food preferences and sensitivity to noise and lights. When Charles Darwin tested the earthworms by placing a piece of food on top of a piece of tin foil to see if the worms would try to dig through the foil. He also learned what food they prefer. He found that earthworms prefer wild cherries and carrots. He also found that the worms prefer fat to meat. Darwin found out how much the worms enjoy eating. The way that Darwin figured out if the worms were intelligent or not was by trying to get the worms to pull and bury things. Darwin tested a sense of the worms by screaming at the worms and blowing a whistle at the worms. He…
The purpose of this experiment is to determine what kind of food the sow bug prefers; decaying leaves, potatoes, grapes, or sow bug food.…
There are times when it is necessary to go through something both inside and outside, literally, to learn. This was exactly the case with virtual lab #11 where the experiment called for an examination of an earthworm’s exterior anatomy and interior anatomy. The earthworm as a whole is considered the dependent variable as we cannot change it. However, the labels to be placed can be moved so they are the independent variables. My hypothesis is quite elementary. I believe that after studying the anatomy of an earthworm I will be better educated about it.…
