process of photosynthesis requires sunlight for its nutrients to make their way into the chlorophyll on green plants. This suggests that without direct sunlight‚ photosynthesis will not be completed correctly or the plants functions will not work properly. Majority of plants that undergo photosynthesis have chlorophyll stored within them‚ it is what gives them their green color. However‚ there are few species of plants that don’t acquire chlorophyll‚ but still undergo the process of photosynthesis. Specific

Solubility of CO2 in water Aim: To decarbonate a bottle of soft drink and find out the amount of CO2 in the drink. * Principle: The reaction between carbon dioxide and water is an example of an equilibrium reaction: Materials: * * 3 soft drink bottles (300ml) * 6g of salt (NaCl) * Triple beam balance scale * Thermometer * Digital scale * Watch glass * Electric hotplate Method: Standing up method 1. An unopened bottle of carbonated drink

two different temperatures a chamber and Logger-Lite‚ computer software‚ were used during this lab. However‚ only data from lab section 1F was analyzed for this report. The goal was to determine if the goldfish’s metabolic rates‚ as measured by oxygen consumption‚ will increase when the water temperature is moderately warm. Alternatively‚ the metabolic rates of goldfish‚ as measured by oxygen consumption‚ will not differ between warm and ambient temperatures. Materials and Methods: Four groups of

Youth is seen as a consuming social group‚ the first to bend to what is understood to be the homogenizing pressures of globalization‚ a globalization fundamentally tied to Americanization.1 Youth consumption practices become an index of the presence and reach of globalization. Such short-hand ways of indexing the salience of contemporary forms of globalization as a cultural force obscure the ways in which new global cultural forms are inserted into

Evidence of Photosynthesis Photosynthesis is the process during which a plant’s chlorophyll traps light energy and sugars (glucose) are produced. In plants‚ photosynthesis occurs only in cells with chloroplasts. Water (H2O)‚ carbon dioxide (CO2) and light energy are required. The light energy is absorbed by the green pigment‚ chlorophyll‚ and is converted into chemical energy‚ which causes the water drawn from the soil to split into molecules of hydrogen and oxygen. The hydrogen combines with

The Concentration of CO2 in the Atmosphere Introduction Carbon dioxide (CO2) is a colorless‚ odorless‚ non-flammable gas that can be produced by cellular respiration and burning of fossil fuels. Many types of industries such as breweries‚ mining ore and the manufacturing of carbonated drinks‚ drugs‚ disinfectants‚ pottery‚ and baking powder; utilize the CO2 gas (Appendix C). Recently Scientist proposed a theory in which CO2 concentration levels above 450ppm will lead to dramatic and potentially

Normally‚ people think CO2 is the chief source that affects global warming; however‚ methane is more dangerous than CO2. Among the total emissions in 2013‚ which was 6‚673 million metric tons‚ carbon dioxide took around 82%‚ while methane was 10%. It seems methane doesn’t occupy much of gas emissions. However‚ the potential power of methane weighs than CO2’s. The level of methane in the air has gradually increased by man-made activities. Methane’s live in the atmosphere is 12 years (EPA‚ 2010). This

Change in respiratory rate during exercise Aim: To record and investigate how the breathing rate varies for the duration of light and heavy exercise. Introduction: When an individual exercises‚ the muscles being used needs extra energy from oxygen. The lungs pump oxygen to the heart‚ and then the heart pumps the oxygenated blood through the blood to the particular muscle that is working. The human body has a series of organs working together‚ which is named the respiration system. The organs involved

the structure of my CO2 car‚ it is considered to be a rail car. There are many features that represent the car as a railcar‚ such as the narrow “rail” that connects the front axle of my car to the back. Typically‚ on a railcar‚ the wheels are located on the exterior of the car‚ unlike a shell car‚ in which the wheels are hidden inside the vehicle. Another distinctive aspect of my car is that the rail is very low to the ground‚ and the front‚ and back (which has to hold the CO2 cartridge) rises up

Introduction The heart is an extremely important organ in the human body‚ and it must be able to adjust the heart rate for when a person is resting or for when a person is running. Heart rate is defined as the number of heartbeats per unit of time‚ usually per minute (Medicine-Net). The heart rate is based on the number of contractions of the ventricles. The pulse is defined as a bulge of an artery from waves of blood that course through the blood vessels each time the heart beats (Medicine-Net)
