survival and when this ability is impaired by the presence of Hydrogen ions‚ our cells cannot function properly. This experiment was conducted to determine if the reaction rate changes in response to a variation of acidic‚ neutral‚ and basic solutions. The experimental results indicated that the basic/high pH solution has a faster rate of reaction in the solution.

needed for photosynthesis. The process of photosynthesis occurs in all plants‚ plants absorb sunlight through the leaves using the chlorophyll pigments in the leaf cells. The carbon dioxide diffuses through the stomata‚ under the leaf. The roots of the plants absorb the water from the soil and then the xylem will transport the water and nutrients upward to the leaves. As well as that the roots also store nutrients and anchor the plant. Plants also need Nitrogen to allow them to photosynthesis. Plants

Cellular Respiration and Photosynthesis Photosynthesis is the process by which plants‚ some bacteria‚ and some protistans use the energy from sunlight to produce sugar‚ which cellular respiration converts into ATP‚ the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy‚ is associated with the actions of the green pigment chlorophyll. Most of the time‚ the photosynthetic process uses water and releases the oxygen. Cellular respiration

OBJECTIVE: The experiment was carried out to investigate the effects of the increase in the enzyme concentration on the rate of reaction. By using self investigative and experimental skills‚ the experiment was done in order to determine how the rate of reaction will be altered‚ whether it will increase‚ decrease or remain constant when the different concentration of enzymes added. INTRODUCTION: Enzymes are produced naturally in plant‚ animal‚ and microbial cell. There are thousands of different

he process of converting light energy captured from the sun into chemical energy that can be used to synthesis glucose is called photosynthesis. This process is used by plants and other organisms for synthesis of lipids and amino acids or can be metabolized during cellular respiration to produce ATP. This process takes place in chloroplasts‚ which is a plastid that contains chlorophyll and involves two interlinked reactions‚ which are light dependent reactions and light independent reactions.

affect the heart rate and what different types of music have a greater affect on heart rate? Music most definitely has emotional value. Heart rate can be directly influenced by these emotional changes. Our group decided to test music tempo’s effect on heart rate. This experiment is relevant to one’s health because it is important to understand how to control one’s heart rate. Before we started conducting our experiment‚ we hypothesized that fast tempo music increases heart rates while slower paced

Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae (Kingdom Protista). Plants need only light energy‚ CO2‚ and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts‚ specifically using chlorophyll‚ the green pigment involved in photosynthesis. Photosynthesis takes place primarily in plant leaves‚ and little to none occurs in stems‚ etc. The parts of a typical leaf

The Effects of Temperature‚ Acetylcholine‚ and Adrenaline on the Heart Rate of Daphnia magna Hieu Duong 6 April 2011 Introduction The heart is a muscular organ that constantly pumps blood throughout the human body. The continuous flow of blood creates a system for vital organs within the body to gain oxygen and nutrients. The timely delivery of oxygen to the body’s organs is very crucial. Brain cells‚ for example‚ will die within minutes if the flow of oxygen is obstructed. For the

Experiment 3. Colours in Kool-Aid Abstract Tetramethylammonium iodide was dissolved in a mixture of of Iodine and 95% ethanol while gently heated in a fume hood. Once cooled‚ crystals started to form in the beaker‚ which were then collected and washed with hexane through a series of processes involving vacuum filtration. Then a mixture of 5mh of the crystals and 5ml of 95% ethanol was created and tested on a slice of potato to analyse the iodine content. After‚ with sodium thiosulphate in
