Carbon Dioxide Understanding and Production in Elodea‚ Snail‚ and Goldfish Introduction This report discusses an experiment to study the rate of aerobic cellular respiration in aquatic organisms which are Elodea (aquatic plant)‚ Snail‚ and Goldfish‚ by measuring carbon dioxide production. Because ectothermic organisms (Elodea‚ snail‚ and goldfish) were placed in completely covered beaker‚ each organism would produce different amount of carbon dioxide. The objective of the experiment is to measure

temperatures below 15°C the gill lamellae of goldfish are largely covered by an interlamaller cell mass which decreases the functional surface area of the gill. The presence of the ILCM in goldfish acclimated to cold water conceivable could lead to a covering of the neuroepithelial cells (Tzaneva‚ Perry 2010). The respiration rate can be determined by how many times the mouth opens and closes. The main purpose of this experiment was to test the breathing rates of a goldfish in room temperature water‚ and the

The goal of this study was to measure the oxygen consumption of goldfish in an ambient environment and dark environment and calculate if there was any difference in metabolism based on oxygen consumption. The experimental hypothesis was that the metabolic rate of the goldfish as measured by oxygen consumption differs in a dark environment than in an ambient environment. The null hypothesis was that the metabolic rate of the gold fish as measured by oxygen consumption does not differ in darkness versus

Ventilation and Oxygen Consumption in Fish Sally Ming Bio 102- PR# 2 12/12/12 Abstract Goldfish (Carassius Autarus)‚ when subjected to warm temperatures will have a high rate of ventilation compared to those exposed in colder environment. In a class experiment‚ we observed and recorded the effects of water temperature at [25 C] warm and [15 C] cold on ventilation and consumption rates in goldfish. For one hour at 15min intervals we observed differences in both ventilation and consumption rates

In ‘Mid-Term Break’ by Seamus Heaney and ‘The Lesson’ by Edward Lucie-Smith a similar impact is achieved through alternative means; Heaney uses language to set up a contrast whereas Lucie-Smith uses irony. Both techniques are striking and subtly interwoven throughout the poems‚ in order to describe the devastating theme of death from a child’s perspective. The techniques selected introduce this emotionally draining theme from a perspective not often considered‚ therefore forcing the reader to empathise

takes months. The image that really stuck out to me was called "Revenge of the Goldfish." I liked this image because of the color scheme‚ as well as how the image told a story. However‚ the image’s story was pretty vague‚ or should I say‚ open for interpretation. It gave the sense of being underwater‚ as well as the goldfish being angry or attacking. It makes me wonder what the people did to the goldfish or one goldfish in particular to make them want revenge. I was very impressed at the amount of

Shouldn’t we accept everyone? Why discriminate someone who is different with views and expressions. The passages I will be using are‚ “Texas v Johnson” by William J. brennan‚ “ In What‚ of This Goldfish Would You Wish ” by Etgar Keret‚ and lastly “ American Flag Stands for Tolerance” by Ronald J. Allen. Barbara Johnson’s quote “we as human beings‚ must be willing to accept people who are different from ourselves ties into these passages. Us humans should accept Johnson in “ Texas v Johnson” even

family has goldfish. We hear about a boy‚ whose mother keeps telling him to be happy‚ even though she has a miserable life because of his insane and abusive father‚ who beats her frequently. One day the goldfish dies and his father‚ being the insensible man he is‚ throws the goldfish to the cat‚ but remarkably‚ Henry’s mother just smiles. The first impression you get when you see the title of the poem is that this must be a ‘feel-good’- or ‘love’-poem. In the first line‚ the word ‘goldfish’ is mentioned

(because of their high tolerance for pollution) assist in the breakdown of nutrients. One reason the goldfish may not have produced as high of a yield as the crayfish is because they are known to produce high levels of ammonia‚ which can be a beneficial fertilizer‚ but in high doses could possibly have a negative effect. When measuring the nutrients of nitrates and phosphates it was found that the goldfish typically had higher levels of nitrates‚ and crayfish had higher phosphate levels. Because of the

One very large difference between What‚ Of This Goldfish‚ Would You Wish and The Brother’s Grimm Version of The Three Wishes is the way the wishes are used. In Etgar Keret’s story‚ most of the wishes are used intentionally and with a certain purpose. Most of the wishes seem to vary depending on what a person in that given situation would want – an elderly lady wants a child‚ a Holocaust survivor wishes for world peace‚ and a Russian migrant just wants something to talk to. In contrast‚ within the
