Essay On Isopod Lab

Introduction- Isopods, or what your 7-year old self would refer to them as ‘Roly-Polys’, are actually a type of class crustacean. They breathe with gills, so they have to stay in damp areas with high humidity. That’s why you normally find them under rocks (Isopod, Pillbug, Sow Bug Information, 1997). Also, they like to eat Detritus and it is a more acidic plant (Animal Behavior: Pillbugs and Their Preferences, 2003-2015). This being said, would isopods refer to be in an area with low pH, high pH or water? I there is a low pH, high pH, or water, then the isopods would prefer the water because most organisms are sensitive to certain pH levels.

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

For two days, on the 14th and 15th of April, a field excursion to Hastings Point, New South Wales was conducted. At Hastings Point, topography, abiotic factors and organism distribution were measured and recorded, with the aim of drawing links between the abiotic factors of two ecosystems (rocky shore and sand dunes), the organisms which live in them, and the adaptations they have developed to cope with these conditions. Within these two ecosystems, multiple zones were identified and recorded, and this report also aims to identify the factors and organisms associated with each zone. Lastly, using data and observations from the past, predictions for the future of the rock pool ecosystem were made.

Isopods typically eat, fruits,weeds, fungi, and animals, both dead and alive. However, when there is a drought the crustacean becomes a scavenger, willing to eat whatever it encounters. Opposingly to these conditions is their behavior when their environment is entrenched by too much water, when this happens Isopods endure a great deal of stress. The perfect medium for them is a damp and cool environment, such as burrows in logs and underneath soil (Brown, 1999). For this experiment we used syrup and water as our independent variables. This was decided because in our prior experimentation it was discovered that the Isopods prefer the environment with water over the dry environment. This experiment was the epitome of taxis, in which the Isopods moved directly towards the environment with water. We then became eager to see if that was applicable to any wet environment or if the specific substance caused the preference to

Describe the main difference between a compound light microscope and a dissecting scope. The main difference between a compound light microscope and a dissecting scope is that a light microscope has a higher resolution and a dissecting scope displays the image in a 3D form.

The isopods have three distinct regions such as the head, thorax and abdomen (CISEO). Their characteristic as for what they look like is their claws attached to their abdomen. Also, they have a pair of antennae, simply small eyes and seven pairs of appendages connected to their segmented thoracic region. They are differed by their stomach

Adaptations allow deep-sea creatures to survive in extreme environments. There are many different adaptations that allow an animal to survive. The three common adaptations consist of habitat, appearance, and diet. The Giant Squid, Zombie Worm, and the Yeti Crab utilized these adaptations to survive, and without them it would be difficult to nearly impossible to keep their species alive and flourishing. Each one of theses species is suited for its environment and survival tasks through its adaptations.

We will put 9 out of the 10 bugs on the dry side of the choice chamber by hand, leaving one in the middle of the choice chamber to make a decision. If the bug walks over to the dry side, as opposed to the wet side, where the bugs are known to be attracted to those conditions, then it will give us the possible theory that pillbugs are communal animals, swayed more by majority rather than their familiar habitat. We will repeat the experiment multiple times to see how many of the bugs can be swayed by the majority, starting with 1, and ending the experiment with 4.

The purpose of the lab is to acquire the percent composition of zinc and copper. The procedure included obtaining a post 1983 penny and washing it with soap and water. Using a triangular file, we made an X on the penny. Then, we cleaned the top and bottom of the penny with steel wool until it was shiny. We rinsed the penny in acetone and dried it with paper towel. Next, we determined the mass of the penny by placing it on a balance. The mass of the penny was 2.47 grams. Afterwards, we placed the penny in a beaker filled with 20 mL of 6 M HCl. In the end we put the beaker in the fume hood and allowed it to sit overnight. During day two of the penny lab, we removed the penny skin from the beaker using tweezers. We rinsed the penny skin with

What different frequencies and types of light would prompt the Spinach leaves to go through the process of photosynthesis effectively?

Daphnia magna is a transparent water flea species found in rocky pools along the Atlantic Ocean. The Daphnia’s body is encased in a clear structure called carapace (Elenbaas, 2013). The exoskeleton, carapace, provides protection for the Daphnia magna, “The portion of the hard exoskeleton, or shell, that covers all or part of the body of many crustaceans…” (“Definition, n.d.). The heart can be easily seen under a light microscope due to the transparency of the skin (Handy, 2012). A variety of factors can change the heart rate of Daphnia. According to Richard Handy (2012), “The heart rate (which can be up to 300 beats per minute) can be monitored and counted in different conditions – for example changing water temperature, or changing the type

This laboratory experiment involving invertebrates is conducted to enable students to investigate Daphnia magna’s responses to external stimuli, therefore developing a better understanding and knowledge of homeostasis that occurs in organisms and the reaction and behavior exhibited by the daphnia magna when varying conditions are exposed to the organism compared to its natural environment conditions (Carter-Edwards et al, 2011). In order to understand the experiment, a foundation of information about the chosen organism such as its natural environment and physiology must be understood.

Some of the creatures included in this diagram are gonodactylidae, coronididae, sculdidae, and such. These are the names of other mantis shrimp. They are all under the category of unipeltata which is used to describe any creatures that burrow, are predatory and aquatic, are stalk eyed, etc. So any stomatopoda is under the classification of unipeltata. It’s easy to get confused with all the complex terms used to explain the phylogeny of organisms so below a diagram is provided so that one can more easily view all the other types of mantis shrimp that exist. The mantis shrimp are mainly differentiated by the appendage they use to strike at their enemy. Below the diagram, there is an image that will allow one to see the appendages and their similarities or

In this experiment I will be investigating the impact of light intensity on the rate of water uptake, due to transpiration, by attaching a shoot from a leafy plant in the capillary tube of a potometer, and then measuring how long it takes for a bubble to move a set distance. The faster the bubble moves, the greater the rate of transpiration. I will be placing one plant in an environment where it is exposed to high-light intensities, and another plant in an environment where it is exposed to low-light intensities.

The Cambrian explosion was a relatively short evolutionary event which occurred approximately 543 million years ago during the Cambrian period. The Cambrian explosion It is referred to as an explosion because it was during the Cambrian period where there was a mass increase of many different multicellular eukaryotic organisms. Fox Douglas, author of What Sparked the Cambrian Explosion, described the Cambrian explosion as an “evolutionary burst 540 million years ago that filled the seas with an astonishing diversity of animals”. This evolutionary event is believed to have caused the development of an immense amount of many different species whom developed below the water surface. It was during the Cambrian explosion where all but one of the
