Recommended: Invasive species notes

In our Worm Behavior lab we observed red worm behavior when faced with different stimuli. Each group has their own trays of worms that they'll have to observe. (10 worms per group) Moist and dry paper towels are needed for this lab along with Corn meal, Lemon Juice, and two other liquids of your choice. And you´ll need to have a chart to record your observations on every 10 minutes. For each trial you need to record your data and observe the worms movements and interactions among each other. Each trial will either support or reject the hypothesis stated. Each lab experiment determines what type of environment red worms are accustomed too. And how they adapt towards different types of stimulus. Do they prefer moist environments over dry …show more content…

Taking perspective of the way they move and behave on their own as their normal behavior. Then, we tested their innate beahvoir towards lighter/darker envirments. FIrst, we used a sheet of paper to cover one side of the tray this represent the dark side. Then, we waited for the worms to move to either the light side or the shaded side. As a result, most worms stayed on the lighter side of the tray. Next, we put a damp paper towel in one half of the metal tray (or petri dish) and dry paper towel in the other half. This dimesntrates wether the red worms prefered moist areas over drier areas. As a result, they prefered moist enviroments rather then a drier one. In our next lab experiment, we tested chemical stimulus. This lab inculded three liquids (Lemon Juice, Kool-Aid and Corn Syrup) along with white paper towels and a tray of worms, each trial waited 10 mintues Each experiment in this lab determined the different types of stimulus the red worms reacted towards. The next thing we tested was the way the red worms reacted towards chemical stimulus. What types of stimulus attracted them the most? In this lab we applyed a couple drops of each substance on a paper towl and observed the way the worms reacted towards it. Our

Isopod Lab Report

1285 Words | 6 Pages

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.

Pillbug Lab Report

125 Words | 1 Pages

In our experiment, we examined the behavior of isopods by conducting the experiment based on our hypothesis: “If ten isopods are put into the test chamber, 5 in sand and 5 in soil, which environment will the pillbug prefer.” We hypothesized that the isopods would favor the soil more than the sand because pillbugs are typically found in soil and not in sand. Pillbugs are favored in soil because the natural role of a pillbug is to eat dead and decaying things but, in sand there are no nutrients available for pillbugs. Pill bugs are mostly found in moist environments, due to having gills, gills only function when they are wet so pill bugs will inhabit places in which air holds a lot of water

Pill bugs (Rollie Pollie): The Effect of Isopod Behavior on Wet vs Dry Stimuli Abstract: There are two main purposes for this experiment. First, isopods were observed so that their behavior could be recorded. Second, we exposed the isopods to a wet cotton ball and dry cotton ball, to determine which stimuli the pill bugs (or Rollie pollies) preferred over the other.

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.

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

Egg Speriment

The egg-speriment was one of the ways to observe how the cell membrane works with different liquids entering and leaving. The egg is a model of the cell membrane that is soaked in vinegar for Days 1 and 2, water for Days 3 and 4, food coloring with water for Day 5, salt water for Day 6, and finally Arizona Tea for Day 7. My hypothesis was when the egg is soaked in vinegar, it will make the shell rougher, water will make it soft, food coloring will make it colorful, and salt water will make it a rocky shell. In this egg-speriment, the manipulated variables is the liquids, the responding variable is circumference, and the controlled variable is the egg.

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,

Bowel obstructions and impair growth mostly affect child and the best way of examining it is by looking through the microscope observing if there are any eggs (Centers for Disease Control and Prevention). Also, a very common symptom is rashes skin, they can also be presented as urticaria. This is an allergic reaction to toxins that poison the worm. It also deteriorates of the appearance of hair and skin. This is because ascariasis absorbs nutrients in the gastrointestinal tract, which means lack of vitamins and trace elements (Mayo

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.

Dangers Through Olfaction And Visualization Of Elephants

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.
