Goldfish and Water Temperature Goldfish and Water Temperature The subject of my observation is a goldfish that is kept in a 2 gallon fishbowl positioned on a window side table. I have noticed that the goldfish is more active in the earlier morning and later evening than during the afternoon hours. Because the table is near a window that faces northeast‚ the fishbowl receives direct sunlight during the time between eleven o’clock a.m. and four o’clock p.m. The goldfish activity decreases around

Amylase And Its Functionality At Various Ph Level Abstract Enzymes can be denatured at various ph levels in which then affects the shape of the enzymes structure and reactivity. The altering of shape causes substrates to not bind in the active site (Scott Freeman‚ Micheal Harrington‚ Joan. C Sharp‚ 2009). Amylase is used as a catalytic enzyme to determine the time period to convert starch into glucose monomers and transport into the bloodstream at different ph levels

The Effect of Starch on the Activity of Amylase with pH Variable Lab Report‚ Fall 2011 East Tennessee State University Department of Biological Sciences By: Shelby Brackett Date Performed: October 10‚ 2011 Lab Instructor: Joseph Kusi Biology 1111‚ Section 018 Abstract Enzymes are very important in chemical reactions. They are used to speed up the reaction taking place. They act by binding to a specific substrate and form an enzyme-substrate complex that may put stress on chemical bonds

Temperature contrast between the equator and the Arctic region is greatest in the winter. Temperatures near or at the equator only change a few degrees between winter and summer while the Arctic region changes drastically up to 40 degrees between the seasons. 2. (a) Were latitude the only

Effect of Temperature on Cricket Respiration Crickets are ectotherms that rely on their environment as a source of heat for their metabolism. Warmer temperatures allow crickets to respire at a greater rate.

process can be affected by several variables; one of the most notable variables is the temperature of the plant’s environment. Previous study has led me to conclude that when the temperature of the plants’ environment is low‚ the rate of photosynthesis is also low because the enzymes responsible for photosynthesis are not able to absorb as much heat energy and in turn will move slower. In contrast‚ if the temperature of the plant’s environment increases‚ the rate of photosynthesis will also increase

The Aim of this practical was to observe what effect temperature had on the permeability of the cell membrane. Introduction Located within the vacuole of beetroot cells is a red pigment call Betalains. Typically these pigments are contained within the cell vacuole by the tonoplast (vacuole membrane)‚ however When beetroot is heated these red pigments escape the vacuole. This experiment aims to explore the effect of temperature on the permeability of the cell membranes (i.e. Tonoplast)

Lab Report The effect of temperature on the reaction between Catalase and H2O2 Sarah AlShemesi In this experiment we’ll be exploring the effects of temperature on the reaction between Catalase and H2O2.We’ll be using five different temperatures to test this. The five different temperatures will be 10‚ 30‚ 50‚ 70 and 90 oC. We will use the liver as a source of Catalase. A 1 gram piece of liver will be inserted into a test tube with 2 cm3 of water‚ then 2 cm3 of H2O2 will be added. The Catalase
