Betta Splendens Research Paper

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.

Background knowledge demands: For this book, students must know what fish and scales are. They will also need to know that fish live under the sea.

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)

The respiration rate for the control goldfish ranged from 123 to 140 breaths per minute, which was not a significant change. On average, the cold-water treatments caused a significant decrease in breaths per minute by the end of the experiment. The average the breathing rates of goldfish subjected to temperatures less than 22°C decreased from a rate of 96 breaths per minute at the start of the experiment, to 56 breaths per minute at the end (Figure 1). The experimental fish in Group #1 ranged from 115 to 50 breaths per minute. Overall, the control fish’s breath rates generally remained constant, and the temperature-stressed goldfish had rates that decreased rapidly from start to finish.

Swallowing is the movement of food from the mouth into the Esophagus. The esophagus secretes mucus and transports the food to the stomach via peristalsis.

Digestion starts in mouth and it is going through several steps. Teeth which are a Mechanical digestion start tearing and crushing the food down into small pieces so that the food will smoothly run down our throat. The salivary glands are located underneath the back of our tongues and that’s what is creating our saliva. The saliva is the Chemical Digestion is helping soften the food in the mouth so it is easy to swallow. Also saliva is the first out of several chemicals that is breaking the food into smaller bits. The tongue is the muscle that works with the food and saliva to form something similar to balls that can be swallowed. Also tongue contains taste buds so that we know if the food is salt, sweet, sour or bitter. Esophangus is a simple transportation tube that is joining the throat with stomach. When swallowing we are closing a trap door in our throats called the epiglottis. By closing this trap we are preventing the food prom going to trachea and into our lungs. Also Food moves down the esophangus using muscles not gravity. Stomach is the first stop after the Esophangus. When the food gets into stomach the stomach uses chemicals to try to make the food smaller. These chemicals are called gastric juices and they include hydrochloric acid and enzymes. (Enzymes are

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

direct calorimetry. Furthermore, the amount of oxygen in the chamber reveals the amount of cellular respiration of the organism. While also, test the effects of decreasing oxygen, and later increasing the heat on the metabolic rate of goldfish. I hypothesize that an increase in temperature will increase their metabolic rate

We performed an experiment on crayfish focusing on their metabolic rates, via oxygen consumption, at two acclimated temperatures. Crayfish were either acclimated to a warm temperature (20 to 25C) or to a

Somewhat more precise descriptions can be made by using the terms poikilothermic and homoiothermic. The body temperature of poikllotherms is relatively variable, while that of homeotherms is relatively constant.

The Crown Tail Betta has a remarkable tail, which is different from other Betta. It is a type of “Siamese” Fighting Fish. These fish have been bred over the years to improve the fins and colors of the male species. It can also make these fish more aggressive. The Crown Tail Betta has a teardrop shape to its tail, whereas the Twin Tail is split, giving the impression that it has two tails.

The male betta crown, also known as Siamese fighting fish, is a popular choice for owners of fish. They have a wide variety of colors and shapes, and are very robust when it comes to adapting to an aquarium. The crown betta has that name by the unique design of the fin with which it has been raised. These fish create a dramatic impression with its vibrant colors and extreme extensions of the

The throat, Pharynx, is part of the digestive and respiratory system, extending from the base of the skull to the level of the lower border of the cricoid cartilage and the 6th cervical vertebra. It is a fibro-muscular tube lined with mucous membrane and is divided into three sections:-

This species is a gorgeous blue pigmented variety of the brilliant butterfly Betta. Its unique colour pattern illuminates to a given degree through the fins where it further progresses to a clear shade. A majestic boundary is created between the two colour pigments i.e. the blue and white colour creating a banding effect that has an overall bull’s eye impression. The exotic colour variations however create an illusion of ephemerality. The super delta tail butterfly betta is bred for its aesthetic beauty; its

The concentration of solutes in the bodily fluids of most marine invertebrates is roughly isosmotic to their environment (Raven, 2008). Because there is no osmotic gradient there is no tendency for the net diffusion of water away from the animal’s cells to occur. When a change in salinity occurs some organisms have the ability to maintain a constant internal homeostasis despite these external changes and are known as osmoregulators (Oxford, 2008). Other animals lack this ability and as such are called osmoconformers; their internal osmolarity matches that of their
