Activities Affecting the Environment Vegetable Gardens The aim will be to produce vegetables intensively‚ in small or larger spaces‚ in the ground or in containers‚ as the situation allows. The establishment of vegetable gardens will also aim to ensure that families have a secure food supply‚ as well as to generate income to improve the participants’ quality of life. Production techniques will be organic‚ and manure or compost will be used to fertilize soil. The types of vegetables produced will

Chapter 13 Questions Name: Lee Jie Min Jasmine‚ Ke Jun Yong Alan‚ Lim Kai Kiang‚ Ong Kim Liang Nicholas‚ Shankra s/o Krishna Date: May 10‚ 2015 1. What are the general requirements for a fatigue crack to form and propagate? The general requirements for a fatigue crack to form and propagate are: The presence of a local plastic stress; The presence of a tension stress; The presence of a cyclic stress (repeated or fluctuating). Eliminating any one of the above three requirements will stop

! ! 1. Describe‚ in detail‚ how to successfully get an image into view. Be as detailed as you can. -In order to get an image into view you must first control lighting by turning switch on. Then pick a slide‚ then select the lowest ocular power (4x) to set microscope into low power. The reposition slide into the circle of light by turning the two knobs located at the right of the microscope. The top knob moves slide back and forth‚ where as‚ the bottom knob positions the slide from side

Factors Affecting Enzyme Activity Abstract: In the following lab factors affecting enzyme activity‚ temperature‚ pH‚ enzyme concentration‚ substrate concentration and surface area will be tested on a beef liver enzyme to see if there will be any effect of performance. By doing 2 or more trials the results will show whether there is an effect to the enzyme from the following factors or not. Some of the factors may denature the enzyme and some will do nothing. Using a table qualitative and the

Biology Coursework: Preliminary Work 8/12/2013 Intro I am going to investigate a factor that affects the rate of enzyme activity What are enzymes and how do they work? Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse - one enzyme will react with molecules

Carbohydrate Digestion The following questions refer to Activity 1: Assessing Starch Digestion by Salivary Amylase. 1. At what pH did you see the highest activity of salivary amylase? Why? 2. How do you know that the amylase did not have any contaminating maltose? 3. What effect did boiling have on enzyme activity? Why? 4. Describe the substrate and the subunit product of amylase. The following questions refer to Activity 2: Assessing Cellulose Digestion. 5. Does amylase use

During this experiment the change in pH of Citric acids is measured from start to equilibrium in mL. This experiment was tested by titration it had two separate trials. Through observations it was shown that the more concentrated acids needed more drops of NaOH to reach its equilibrium then the less concentrated acids. Introduction Sodium Hydroxide (NaOH) is a strong base and when it is titrated with a strong acid the equivalence point will be expected to be a pH of 7 (wyzant.com‚ Feb. 12). NaOH
