Transpiration Lab Write Up

Transpiration Lab Write Up Purpose/Question: How do environmental factors affect the transpiration process in plants? Research: Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. It occurs chiefly at the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis. Transpiration is not simply a hazard of plant life.It is the â€Å"engine† that pulls water up from the roots to supply photosynthesis (1%-2% of the total), bring minerals from the roots for biosynthesis within the leaf, and cool the leaf. There are four different conditions that affect transpiration. They are wind, humidity, heat, and light. These four conditions may change rate of water loss through transpiration by either losing more water, or less. Plants have adapted to create the C 4, and CAM pathway. In the both pathway the plant takes CO2 and stored.Since CO2 can be taken up and stored for later use in photosynthesis, the plant reduces water loss by having less stomata open during the day since most of its needed CO2 has already been taken up at night. With the abundance of CO2 stored, the plant can then use the stored CO2 for photosynthesis and reducing photorespiration by reducing or completely eliminating accidental O2 uptake. Materials: 1) 5 small plants 2) Fish tank 3) Water spray bottle 4) Water 5) Heat lamp 6) Fan 7) Regular lamp 8) Mass weighter ) Place to record weight Procedure: Place Lamp, Heat lamp, fan, and fish tank in different areas where they won’t affect the other. Spray the fish tank with water and to make a humid environment and keep spraying everyday to ensure the tank is wet. Water all of your plants. Weigh all the plants on the original day, Monday, and record the weight. Place a plant in every condition. With the extra plant, p lace it in an area without a specific condition to use as a control plant. Do not water the plants the rest of the week.Every day, weigh the plants and record its water loss for every plant. At the end of the week, create a chart for the amount of water loss and compare with the control plant.

In conditions such as wind, when there is no breeze, the air surrounding a leaf becomes increasingly humid thus reducing the rate of transpiration. When a breeze is present, the humid air is carried away and replaced by drier air. The opposite of that is the humidity where the plant lost very little water. It lost very little water because its environment was wet, so the plant did not need to diffuse much water.In heat, the air was hot and dry, so the plant lost water because it’s surrounding needed water to cool it down. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises. At 30 °C, a leaf may transpire three times as fast as it does at 20 °C. Finally, light lost a steady amount of water because plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (mechanism). Light also speeds up transpiration by warming the leaf.I expected these results because it makes sense and I researched before completing the experiment. Some avoidable errors that could have happened would be accidentally splashing water on a plant or putting the conditions too close together. Some unavoidable errors could be the weather outside. Even if the experiment is conducted inside, the hot summer air or cold winter air could drift in the room, affecting the plants transpiration rate. Some further investigations I would make are things such as whether the type of plant affects the rate, or if the type of heat lamp or fan will change the results as well.

Race and gender

Race and gender The major foundation and the cornerstone that binds a given people together, aside from the tribal affiliations is the race to which each of us belongs. Stereotypes aside, the perceptions that we hold or believe in to a large extent determine our attitudes towards a certain group of people who fall within the brackets of these labels.Advertising We will write a custom essay sample on Race and gender specifically for you for only $16.05 $11/page Learn More In the movie Race, the Power of Illusion†, a rather uncommon path of argument is explored on one issue that has been rather fundamental to the whole human race yet it is ignored much of the time it come to light. The movie explores race and the assumption human beings behold in relation to this aspect of our social life, and explores the possibilities that lie beyond these daily perceptions(Money, 1994). Questions abound though, is there any slightest possibility of the existence of the idea that huma n beings can be categorized and handled differently depending on their racial affiliation? Are whites generally at an advantage as a result of our institutions taking heed to the perceptions that white people are superior? A difference in opinion over what race is superior above the rest has resulted to mayhem in any two wrangling societies with different races. This is evident in testimonies that bear stories of tribal cleansing, war and even in sensitive areas such as the rules that affect immigration among different countries. The debates about race have dominated almost all spheres of our social lives yet all of us, whether racist or not do not question the truth behind this. Scientific evidence discards the whole behind â€Å"race† as a myth, one that is not at par with the times or rather Neanderthal. A long history of research and analysis of the differences among the different races has yielded only one result; that racial differences go only skin deep (Buss, 2001). T he intrinsic delicate features that comprise the human DNA do not show any difference between people of give races. Gender identity, on the other hand is another aspect of social interventions that influence our interactions. It s not a state of inexorableness, rather it is just an attitude that people link to certain qualities that comprise character.Advertising Looking for essay on social sciences?

A break down of this scenario would to put into perspective this thought; that people inherit their sex, and not their gender. For instance, biologically, one’s sex is determined by the result of the interplay of the chromosomes physically expressed through the reaction of hormones and other organs such as the reproductive organs. Contrary to this, somebody’s gender is to a large extent determined by the society and the norms that define the lifestyles of a given people (Gould, 1996).). The societal perception about masculinity and feminists is to a large extent dictated by their social behavior and what the different cultures practice as norms. One school of thought advocating for this idea purports that had people’s characters and behaviors’ be dictated by the differences that arise out of their biology, then the differences universally would widen. Higher hormone levels would lead to increased activities, and that in many places their reactions would be alike irrespective of the geographic locations. If ones’ sex would automatically determine their gender then it would subsequently follow that all men and women would have uniform characters. References Buss, M. D. (2001).

Tesco Supply Chain Management Practices Case Study Essay

Tesco Supply Chain Management Practices Case Study - Essay Example They were the authors of the book known as ‘The Machine that changed the world’ which was in charge of introducing the concepts of lean production for the Toyota Company (Indu & Gupta, 2004). The experts found out that the company indulged in many unnecessary handlings whereby there would be improvements along with reductions in the costs the company incurred. They additionally found out that there were longer lead times, poor availability of products along with locations of stores. The company in turn established a system for continuous replenishment, which enabled their products to have immediate replenishment (Womack & Jones, 2006). They have also been reducing their handling of goods while also streamlining their flows. They were able to accomplish this by using dollies on wheels, which replaced shelves. The dollies could be sent from the suppliers and into their delivery Lorries and taken back to the stores. They helped in reducing the companies need for handling th e products since their products were just being loaded at the end of the company’s production line and taken directly by wheels to their supermarkets (Ohno, 2005). This move helped the company in reducing their touch points for drinks by 150 locations along with the transit times. However, the multiple trips that were carried out resulted in higher costs for the company but these costs were covered by decreases in their inventory costs. The company also had agreements with other companies such as P&G, Unilever along with Coca Cola in order to alter their schedules for distribution (Womack & Jones, 2006). This in turn enabled them to reduce their lead times by fifteen days since the daily deliveries made through their wheeled pallets, which enabled the placement of their goods directly on the shelves of many of their outlets (Bicheno, 2008). The company’s holding of stock reduced greatly from over four to two weeks while their service levels also improved by over six pe rcent. The company’s use of lean production methods in the above aspects helped them see their profits jump from 16,452 million pounds in the year 1998 to 37,070 million pounds in the year 2005 making them the biggest grocery within the United Kingdom (Indu & Gupta, 2004). Due to the company’s use of lean production systems, they were able to reduce their storage locations from five to two, their order entry locations from six to just one and their service levels from 98.5% to 99.5%. They were additionally able to reduce their throughput times from twenty to just five days, which represented a 75% reduction in their total inventory (Womack & Jones, 2006). The Tesco Company initiated a ‘step change’ curriculum, which was used for identifying the processes in their supply chains that required transformations. This program helped the company in eliminating several of the unnecessary procedures that enabled them to save about two hundred and seventy million po unds in the years 2004 to 2005. The changes that were implemented under the program additionally helped in simplifying the operations in their stores while freeing up their employees so that they could more effectively attend to their customer’s needs (Ohno, 2005). The company introduced operations across docks that involved goods being loaded into one

Price Elasticity of Demand Assignment Example | Topics and Well Written Essays - 500 words

Price Elasticity of Demand - Assignment Example If more farmers decide to produce corn, the demand will be met. The price of soybean in relation to corn also matters. The increase in the price of corn prompts demand for soybean but demand for soybean also depends on tastes and preference and income. Although the price of soybean decreases, it does not result to increase in its demand since preference is on corn which has multipurpose use hence income will be spent on corn and buyers will incur the opportunity cost of buying soybean. Since both kinds of cereal use same raw materials, farmers will shift production factors from a production of soybean to corn production hence reducing acreage on soybean for planting more corn. The price of commodities is determined by forces of demand and supply. As long as the quantity of corn oil produced is equal to quantity demanded, the market will be at equilibrium price and quantity. Since the demand for corn is up it means demand for corn oil is also up hence quantity demanded is higher than quantity supplied. The buyers will compete for the available corn oil hence pushes the prices up. Baumol & Blinder (2009 p 57) argues that quantity demanded is also dependent on; income, tastes, the price of other products and population size. If the price of corn oil goes up, buyers in response to price change will cut a quantity of demand of corn oil to alternative sources of energy which are cheaper especially if the price elasticity of demand of corn is high. If buyers have increased income and have high-income elasticity they buy more corn oil thus increasing demand and pushing prices up. PEoD is used to measure the response of consumers demand to price changes all factors held constant (Moffat, 2010). It’s the proportionate change in quantity demanded over a proportionate change in price. PEoD is affected by factors such as; substitutes, a degree of luxury, time period and price points (Bochholz, 1996). The higher the price elasticity, the more sensitive consumers are to price changes (Moffat, 2010).  Ã‚
