practical 1 is to determine the rate of photosynthesis by measuring the rate of oxygen production‚ which is a direct consequence of PSII activity. Results Graph 1 Graph 2 Discussion i. It took 2 minutes before any increase in the O2 concentration of the chamber was observed‚ it took 2minutes‚ after illuminating the leaf. ii. There are 2 main parts of the photosynthesis‚ light dependent part and light independent part‚ the O2 is released in last part which is light-independent part. Also it takes time

Part 2: Safe work with large inductances 1. One of the main hazards of using inductances is electrical energy stored in the magnetic field. If a circuit containing an inductance is interrupted then the stored energy can release through air (forming an arc). This can destroy a switch contact‚ burn fingers‚ create other damage. In the circuit of Figure 1‚ show how to mitigate the risk (pay attention to polarity!). We give the elements in this circuit some simple values for the purpose of

In photosynthesis‚ light energy is transformed into chemical energy‚ thus chemical energy is the product. This is different from respiration because respiration transforms chemical energy into energy usable by cells; in this case chemical energy is the source. Photosynthesis occurs in the chloroplasts‚ using the chlorophyll inside of the chloroplasts‚ while respiration occurs in the mitochondria. Photosynthesis produces oxygen as a by-product‚ while aerobic respiration requires oxygen to even work

result in many American casualties; as a result‚ the atomic bomb was later dropped on the Japanese city of Hiroshima. This attack on Japan would later become one of the most controversial attacks in history‚ many saying that the atomic weapon was not necessary. The dropping of said bomb has different views depending on the perspective one is looking from; whether it be political‚ ethical‚ or from a military perspective‚ the atomic attack is very controversial. From the political perspective‚ the atomic

urpose: The purpose of this lab is to determine the impact of light on the germination of seeds Research: A seed is the reproductive unit of a plant that contains a mature ovule with an embryo. The seed is made up of the seed coat hard shell over the seed‚ two cotyledons‚ fleshy membranes that store food‚ an epicotyl‚ which forms the primary shoot‚ the radicle‚ the primary root of the seed‚ and the hypocotyl‚ the stem of the epicotyl. When the seed is triggered by water to sprout‚ a process called

INTRODUCTION There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease to knowing the correct microorganism in order to make antibiotics. This study was done by applying the following methods; OF Glucose‚ Indole Production‚ and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous

Public order is necessary because without it the chaos that would unfold on to our society would surely put an end to any civilization that would exist. In todays society I think that we are lacking public order in certain areas and trying to make it up in others which impends on our societies ability to function as a "free democratic society." By this‚ for example‚ our gun control laws are focusing more on removing the weapons from law abiding citizens and basically handing over our protection to

block in the progress of society. A good job or money is not everything; knowledge and education are more than that. Just pursuing a degree may not guarantee you a lucrative job but studying at a college may develop such skills in students that are necessary to lead a prolific life. It is the knowledge of education‚ knowledge of empowerment‚ knowledge of responsibility and the knowledge of curiosity which makes a student an intellectual personality – but not the degree he pursues nor the institution

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

would normally be able to solely survive. They are found on every continent‚ ranging all the way from the freezing Arctic to the sweltering grasslands of Africa. Even though they can live in such extreme conditions‚ they do require clean air. This is why they are excellent environmental indicator. An indicator species is an organism whose presence or absence reflects the overall health of an environment. Lichens flourish where there is good air quality; however‚ they cannot survive where the air is
