Using different chemical seed soaks to improve the rate of germination A 2013 Year 9 Science Project by Josh Martin Class Level 1 with Mr Box Abstract: The purpose of this investigation was to determine which out of five readily available chemicals was the most effective at scarifying seeds to improve the rate of germination‚ and what concentration of the most effective chemical was the most efficacious. Ten seeds for each of the five chemicals hydrogen peroxide‚ glucose

Biofuel Enzyme Kit Katie Adamson Biochemistry Laboratory‚ BIO124L 1/29/15 Abstract The objective in this lab was to determine the effects different conditions had on the enzyme cellobiase. We examined reaction rates in the presence or absence of an enzyme‚ the effects temperature and pH changes on the enzyme and the effects enzyme concentration and substrate concentration had on the enzyme. As expected results showed us that cellobiase works optimally when conditions are favorable. We see this

A company has specified that the acceptable size of a knob that is to be produced is (0.140 ± 0.003) inches. In this lab‚ the dimensions of the knobs produced in one day are tested for discrepancy in order to pass control testing. This lab also reports the probability that knobs with the acceptable dimension will be produced. MATERIALS AND METHODS Using Microsoft Excel‚ a histogram was created displaying the three documented dimensions of 15 batches of knobs. This histogram was obtained in order

Introduction: According to chemists‚ hydrolysis is defined as the breaking of a compound involving a reaction with a water molecule. The goal of this experiment is to three-dimensionally show how disaccharides are transformed into monosaccharides using an acid-catalyzed hydrolysis reaction. For the purpose of this lab‚ it is quite useful to fully understand the following terms: optical rotation and carbohydrate. Optical rotation is measured by a polarimeter‚ which measures the polarization of light

Transpiration Formal Lab Report By Jessica Tran Introduction When water is transported from the roots to the mesophyll cells in the leaves‚ it is evaporates out the stomates‚ called transpiration‚ to create a lower osmotic potential. Osmotic potential is the part of the water potential of a tissue that results from the presence of solute particles. Even though the stomates open to release water‚ it also brings in carbon dioxide to produce sugar and oxygen through a process of photosynthesis

of (E)-Stilbene 1. Addition reaction is a reaction that involved two molecules that combine to make a larger product. Addition reaction has two main types‚ electrophilic addition and nucleophilic addition. An electrophilic reaction is when the pi bond of a molecule is removed to make two covalent bonds that are bonded to two new molecules. A nucleophillic addition is a reaction that removed the pi bond from a molecule and adds covalent bonds with two new compounds. Halogenation or most commonly

Biomolecules - Organic compounds is first due to the fact that every word on the list is an organic compound‚ as they are essential to life processes. Next‚ carbohydrates‚ lipids‚ proteins‚ and nucleic acids are all macromolecules‚ as they are very large molecules composed of thousands of atoms or more. The map then divides into the four biomolecules. Carbohydrates are composed of monosaccharides‚ disaccharides‚ and polysaccharides. Proteins are made of amino acids‚ which are themselves made of polypeptides

For this to happen‚ the molecules need to dissolve through a partially permeable. Osmosis is the diffusion of water as it goes from dilute to a more concentrated solution. Active transport is the movement of molecules from low concentration to high concentration against the concentration gradient. Energy is required for movement to occur.
