Fish Respiration Vs. Temperature Lab Report

Before the experiment, several pieces of glass were put into an oven to dry, and the heat from the

When placing the large test tube in boiling water, be sure to keep the face of the large test tube away from you or any lab partners with safety tongs.

This lab was conducted with the purpose of confirming the trait of homeostasis among goldfish. During the experiment, it was recorded that the fish would increase gill movement when placed in colder water two out of the three trials. However, the results showed no significant difference in gill movement in various temperatures of water. This has very little effect on the broad field of science since our only three trials were performed and may have included human error in the trials.

Ectothermic animals are animals whose body temperature is affected by their surroundings. This means that if the environment is cold the animal will be cold. If the environment is warm the animal will be warm. This is because the animal doesn’t have the capability of regulating its body systems to keep a constant body temperature. When an ectothermic animal is cold, its heart rate will lower. When the animal is warmer, the heart rate will raise – as long as the temperature isn’t sufficiently high to harm the animal. (Campbell, 2005)

Once the experiment was concluded, aged water was slowly added to the temperature- stressed fish in order to raise the temperature of its water. This helped to return its environment back to normal conditions.

13. Which of the following is not an expected response in a fish to a drop in water temperature?

Freeman (2008) furthers Eckert et al’s argument by stating that the actin filaments of the muscle cell in organisms are able to intake ATP (adenosine triphosphate) faster and will move the organism faster when higher temperatures are imposed. This is because of an increase in enzyme reaction rates (Freeman 2008). These arguments can be applied to our experiment to help explain the trends observed. It can be argued that as the Gammarus setosus experiences the cold treatments, the organ of Bellonci senses the cold temperature, which in turn signals the organism to preserve its energy to protect itself; therefore, the organism will swim slower. In addition, the enzymes in the muscle cells of the organism, when experiencing the cold treatments, will have decreased ability to carry out enzymatic reactions, therefore inhibiting the uptake of ATP, which will cause the organism to swim slowly. Conversely, as the organisms are put into the heated treatments, the organ of Bellonci senses the heat, and allows the organism to swim faster, since it does not have allocate as much of its energy towards survival. Furthermore, the enzymes in the cells will be able to catalyze reactions more quickly, therefore allowing the organism to swim faster. However, when the temperature of the surroundings is too high, the enzymes will denature, therefore, reducing the activity rate of

Crayfish, Orconectes propinquus, are ectotherms that do not generate internal heat and rely on external temperatures to determine their body temperature. The crayfish we tested were found in Medway Creek and therefore undergo considerable temperature changes throughout the year. Since these crayfish are able to adapt to various temperatures allowing them to live in numerous places, their survival rate would be higher than many other organisms.

Animals differ in their abilities to regulate body temperature (thermoregulation). We sometimes use the terms "cold-blooded" or "warm-blooded." Most reptiles feel cold to the touch, while mammals and birds often feel warm.

Why is the cold tolerance for different population varies whereas the heat tolerance is similar for both marine and fresh populations?

The example given is the coral trout, a fish that is commercially important. Since the water temperature has risen higher up in the water, these trout tend to be more lethargic now; they stay lower in the water. This is crucial because all of their hunting and mating ground is higher

(Heldmaier,1981; Kronfeld-schor et al. 2000; Bao et al. 2002; Jefimow et al. 2004; Li and Wang, 2005; Zao and Wang, 2005). These experiments helped discover the many different thermoregulation responses in endotherms and specifically, rodents. Knowing the depth of these studies given above makes investigating this relationship very interesting because we have the ability to discover not only more knowledge about this relationship, but also about the other possible thermoregulatory responses that may occur in endotherms that has not yet been exhibited. R.P. Stated in the Investigating Biology lab manual these variety of responses can also include “photoperiod, ambient temperature, food availability…”(French, 2015). In order to test this relationship and its responses we will test the hypothesis as stated above: Endotherms have a more active metabolic rate when exposed to temperatures above or below ambient due to the thermoregulatory responses to the extreme environment. This study is different from any other that preceded it because it directly compares the responses of thermoregulation in different atmospheres. The study also has the possibility of being published in JIBI. For this new path of experimenting to be published, and

The solid water was the control variable in the experiment and the investigators compared values that resulted from irradiation of the solid water with each bolus’ average Dmax. Table 1 recorded the ratios that resulted from these values. ANOVA calculations from the values shown in Table 1 resulted in an F value of 762.65 and a P value of less than 0.0001. The investigator compared the results between each individual group with a Tukey HSD test. When compared to one another, each sample resulted in a P value less than 0.01.

Cold-blooded fish beat the birds when it comes to surviving the cold. The marine creatures can survive in water even if the temperature goes down to 37 or 38 degrees, Konrath said, The Chicago Tribune reported. The fish does not bulk up throughout winter but instead slow things down by eating only when it can.
