Red Worm Behavior Lab Report

In figure 1.1 we can see the reusults for only the pillbugs in the light, hot, shelter, and moist chambers since the results showed these were their greater likings. In figure 1.2 we can see the light (COLOR), hot (), shelter (), and moist () results to see how many left that spot, came back and then stayed until the amounted time was up. Pillbugs seemed to be more attracted to the light and had an average number of 6 isopods, over 4 in the dark chamber. We see in figure 1.2 that pillbugs had a greater average in the hot, sheleter and moist chambers, with averages of 7 and

This behavior was observed in all the three experiments and through the period of observation, isopods seemed to move to different sponges before they settled down behind one of them. The χ2 value was 0.03842932, df was 3 and hence the P value was less than 0.001 which proves that this result is not a result of random probability and is in fact significant and reliable. In Trial 2, the hypothesis was that most isopods would go to the sponge with sucrose solution and our hypothesis was proved correct through the experiment. It was observed that a majority (55%) of the isopods preferred sucrose relative to the other sources of moisture.

The Jumping Bean Beetles! The Jumping bean beetles experiment was done to study the oviposition in bean beetles, and whether it is based on the heritage of the bean beetle. The study consisted of two different types of beans and several mung raised bean beetles.

Odorants are that are attractive to C. elegans are usually alcohols with 4-6 consecutive carbons; any fewer or additional carbons are repellant to the worms. The substances used to dilute these alcohols are referred to as carriers. In this experiment, ethanol is used as a carrier. An example of a diluted odorant that is attractive to C. elegans is isoamyl alcohol (Bargmann, 1993).

I hypothesized this because I believed I cut the worm into two fairly even pieces and they had the same amount of time to grow. For the “head” segment, the initial measurement was five millimeters, and from the very beginning, I noticed that this segment was a lot more active and moved around more than its counterpart. For the first week’s measurement, the worm segment stayed the same at five millimeters, but I noticed that a tail was starting to form on the “head” segment and the segment still remained very active. The second week’s measurements was a six millimeter “head” segment, a one millimeter growth throughout the whole experiment. The tail had almost fully formed itself for the “head” segment and there was still a lot of mobility.

The intensity of the light used in this experiment was mild and therefore the reaction to the stimulus by the sow bug was mild and inconclusive with the expected reaction. A possible secondary reason that the observed reaction differs could be due to the bugs distraction with trying to remove himself from the container as a whole. The hypothesised response was that in the presence of a light stimulus the pill bug would favour the darkened side of the reaction chamber in a negative taxis responded. This hypothesis is based off of the previous knowledge base of the sow bugs natural habitat, which happens to be described as a damp and dark environment (Muskopf,

If a cow (the intermediate host) consume contaminated vegetation, it ingests mature eggs or gravid proglottids. When humans consume poorly cooked meat, they become infected by the worm. Adults attach to the intestinal wall with their scolex using four

The methods of this experiment are really simple. When we started the experiment we all washed our hands and wore gloves. Each group member did their part to conduct and successful experiment, one group member plugs the Bunsen burner to the gas pipe and turned on the gas, then used flint spark lighter to set the flame on the Bunsen burner. While the second group member is setting the dissecting microscope and making sure the lenses are clean. This member is getting all three Petri dishes ready to examine (first Petri dish contains E. coli, the second dish have the mixture of C. elegans, the third dish is where we are transferring female C. elegans to mate up).

Worms were and are very successful in adapting to their environment. They were able to go out to get food at a specific time and watch out for predators. Also, they had to get used to living underground in the soil until they knew the birds wouldn’t be out so that they could get their own food. These adaptations are helpful because if they had not adapted the birds and other animals would have a lot of snacks to eat. The worms

This sample would be the control of the experiment Secondary Research • Find information about how plants interpret sound on the internet and in books. • Analyse data collected by other students or scientists. THE EXPERIMENT Hypothesis: Playing classical music to plants everyday will increase their growth, thus showing that plants can actually respond to sound. Variables Controlled variables: • The environment- both containers were kept in the same room.

The glow worm or the arachnocampa luminosa is an insect that has a bright green light up tail. The glow worm can live pretty much anywhere on earth that’s not artic. The glow worm is an carnivore so, it eats snails, slugs, or other insects. It has a hard shell to protect it from predators. One of the cons of this insect is it is threatened.

Diagnosing whipworms can be challenging due the fact that the eggs are dense making it harder for them to float to the top of the vial. The use of a sugar solution and centrifugation can make the detection of eggs easier to see. We will then take the sample and look at it under a microscope. Due to the nature of these parasites there are some complications in diagnosing them. Animals infected could show clinical signs before eggs are even shed in the feces, therefore, we may not see them under a microscope and would have to diagnose based on the clinical signs shown.

After smelling the different cloths, the animals had a faster reaction time and moved farther away from the cloth worn by Maasai men. Their quick senses indicated a sense of fear, taking the smell as a sign that a predator was nearby. In these cases, the elephants also exhibited movement towards areas with tall grasses to hide and take shelter when close to potential dangers. For an emphasis on the visual aspect of the study, the experimenters laid out unworn cloths in red or white. The elephants became more alert and reactive to the red ones versus the white ones, showing their ability to recognize a color of caution.

This experiment has to be carried out carefully

Materials: • Preserved Earthworm • Dissection Tray • Gloves (optional) • Safety goggle (optional) • Lab Apron (optional) • Scalpel • Probe • Dissecting Pins Method: • Earthworm should be taken from a preserving chemical as it prevents the earthworm`s organs from rotting. • Lay the earthworm on a dissection tray when dissecting as it holds the earthworm`s body in to place. • Gloves, lap apron, and safety goggle protect the hands, body, and eyes from any exposure to bacteria and chemicals while dissecting. - These equipments are not mandatory but are optional when dissection. By using these equipment, you are protecting yourself from any exposure to chemicals and bacteria.
