Temperature can determine the chemical reactions in metabolism. When temperature is high, chemical reaction will increase which will have more metabolic activities. In contrast, when temperature is low, metabolic activity will decrease. Metabolic level has an high impact on activity levels. Thus, temperature will affect C. nemorails’ activity level. As temperature increases C. nemoralis’ activity level will increase and as temperature decreases C. nemoralis’ activity level will decrease. However, C. nemorails cannot adapt to temperature above or below its tolerance temperature 8-22C or else they remain at rest or their activity levels will be relatively low.

Indeed, Grove snails at 0C there are only 47 Grove snails that are active, while Grove snails at 26C there are 251 Grove snails that are active. Therefore, snails are more likely to be more active in a higher temperature. Between 8-22C at 8C there are 248 Grove snails are active. As temperature increases when it reaches at 17C there are 273 Grove snails that are active. At 17C the Grove snails is at its optimum temperature and as temperature increases and reached 22C active Grove snails starts to slowly decrease to 270 Grove snails. Comparing to all temperatures, we can see a huge difference between number of active Grove snails at different temperatures. Indeed, temperature affects Grove snail’s metabolisms. If metabolism slows down then their activity levels will also decrease. Grove snails are ectotherms so they regulate their body temperature by taking advantage of surrounding temperatures. Since they are ectotherms they are only able to adjust their body temperature within certain temperatures and their body temperature will fluctuate with the environment. Ectotherms will have blood all over their body and if their blood are warm it will activate the body cells and it will increase the metabolism rate in the body.
After results, it was concluded that isopods prefer normal temperature conditions over warm conditions. We created these environments by adding water onto filter papers with the accounted for temperature measurements. The reason for the results could be seen in a usual isopod environment, it is usually dark, fresh, and moist, and the normal water temperature being the closest to that was the reason for their choosing. The Isopods seemed to locate the appropriate environment by the use of their antennas. For the investigation the normal water and warm water temperatures were independent variables. The observations were the control. The isopods behavior served as the dependent variables. The isopod behavior would be classified as movement in response to a cooler temperature environment taxis. All in all the hypothesis, “If the isopods are exposed to normal and warm temperatures then the normal temperature will be preferred” proved to be
However, the increased temperature of the new acid solution was at a greater temperature than the ambient temperature and the temperature of the water. This suggests that some of the results obtained were partially due to the fact that some of the heat energy of the acid was transferred to the water, as well as the hydration of ions present in solution. An improvement would be to create the solutions of desired concentration and allow them to reach thermal equilibrium with the surroundings. This would allow more accurate results and the allow for the assumption that the temperature change observed during the experiment would only be due to hydration of
As temperature increases, rate of respiration increases, because particles move faster and with more energy, which in turn means more particles collide with enough energy to react. However, as temperature increases, enzyme stability decreases, so at temperatures above the optimum temperature, the rate will decrease, until all the enzymes have been fully denatured and all the active sites have been lost. Enzymes speed up reactions in organisms. Each enzyme works on a specific substance, called its substrate. The diagram below shows an “E” (an enzyme) catalysing the breakdown of “S” (the substrate) into two different products (“P”).
The Effect of Light on the Organic Plant Elodea Aim: To calculate the rate of photosynthesis from the number of oxygen bubbles produced by the plant. Photosynthesis: The process by which green plants use the sun's energy to build up carbohydrate reserves. Plants make their own organic food such as starch. Plants need Carbon dioxide, water, light and chlorophyll in order to make food; and starch and oxygen are produced. Carbon dioxide and water are the raw materials of photosynthesis.
Artemia franciscana, known commonly as Brine shrimp, are aquatic arthropods within the animal kingdom who can readily adapt to extreme conditions. While they mainly live in saltwater lakes, such as the Great Salt Lake and the Caspian Sea, Artemia are able to survive in most inland saltwater excluding ocean (Gonzalo and Beardmore, 2012). Their main source of nutrition comes from Phytoplankton and microalgae: organisms that require sunlight to prosper. In addition, Artemia reproduces both sexually and through parthenogenesis, processes that require specific abiotic conditions for temperature and salinity*. In fact, Wear et al. (1986) states that higher temperatures are more effective in reproduction and maturation of Artemia. Primarily, this experiment is important for acknowledging the ecology of Artemia as well as their biodiversity in a time of climate change. Understanding habitat requirements is essential in aiding preservation, survival and reproduction.
The Effect of Light Intensity on Photosynthesis Of Elodea Canadensis Introduction I wanted to find out how much the light intensity affected the Photosynthesis in Elodea Camadensa. I decided to do this by measuring the amount of oxygen created during photosynthesis. Photosynthesis is the procedure all plants go through to make food. This process uses Carbon dioxide, water and light energy. It produces Oxygen and Glucose.
A fall in core temperature can also lead to increased voluntary muscular activity such as
During the Trials in Part A, a difference in temperature was also observed, but not to large extremities. The temperature Increased 1 degree Celsius in A1 and A3 (27 to 28 Degrees Celsius)
The effect of different temperature on molecules will either cause an increase in kinetic energy with increasing temperature or decrease in kinetic energy with decreasing temperature. This change of kinetic energy will affect the activation energy required for a reaction to occur. So, with a rise in temperature less activation energy is needed, thus the rate of fermentation will
The Artemia franciscana can survive in extreme conditions of salinity, water depth, and temperature (Biology 108 laboratory manual, 2010), but do A. franciscana prefer these conditions or do they simply cope with their surroundings? This experiment explored the extent of the A. franciscanas preference towards three major stimuli: light, temperature, and acidity. A. franciscana are able to endure extreme temperature ranges from 6 ̊ C to 40 ̊ C, however since their optimal temperature for breeding is about room temperature it can be inferred that the A. franciscana will prefer this over other temperatures (Al Dhaheri and Drew, 2003). This is much the same in regards to acidity as Artemia franciscana, in general thrive in saline lakes, can survive pH ranges between 7 and 10 with 8 being ideal for cysts(eggs) to hatch (Al Dhaheri and Drew, 2003). Based on this fact alone the tested A. franciscana should show preference to higher pH levels. In nature A. franciscana feed by scraping food, such as algae, of rocks and can be classified as a bottom feeder; with this said, A. franciscana are usually located in shallow waters. In respect to the preference of light intensity, A. franciscana can be hypothesized to respond to light erratically (Fox, 2001; Al Dhaheri and Drew, 2003). Using these predictions, and the results of the experimentation on the A. franciscana and stimuli, we will be able to determine their preference towards light, temperature, and pH.
For years farmers have been adding natural fertilizers to their crops. It is a big risk though. Over fertilizing is very dangerous. It puts high concentrations of salt into the soil. It can also affect the water resources nearby. Nitrogen, Phosphate, and Potassium are the basics of fertilizer. If a certain nutrient is short in supply the fertilizer might not work as well. Calcium, iron, manganese are also nutrients that might be needed. So don’t just trust the fertilizer bag that says it has all the nutrients, test it out. (Miller and Levine 717)
Aim of the research: The aim of this investigation is to determine what kind of effect will the increasing temperature have on the plasma membrane of a beetroot cell.
Input variables In this experiment there are two main factors that can affect the rate of the reaction. These key factors can change the rate of the reaction by either increasing it or decreasing it. These were considered and controlled so that they did not disrupt the success of the experiment. Temperature-
The aim of my investigation is to find out whether the increase of temperature increases the rate of reaction between the two reactants of Sodium Thiosulphate and Hydrochloric acid. I will then find out and evaluate on how temperature affects this particular reaction. Factors There are four main factors, which affect the rate of reaction that are considered as variables for the experiment I will be doing, they are the following: Molecules can only collide when two of them meet together.
