The results of this experiment showed that with increase in oxygen concentration, there is rapid increase in the heat energy relesed and also the amount of carbon dioxide released. The test for carbon dioxide was lime water which turned white on the passage of carbon dioxide. The amount of energy released could be told by the temperature on the bottle( caroline,28)
To both the plants and animals energy is the most fundamental driving factor. Almost all processes in the bodies of the organisms are initiated and run by energy. These processes ranges from reproduction, locomotion, fertilization, growth and development. This calls on scients like me and others in general to clearly show the factors which contributes to the respiration in organisms. It is of essence to note that the experiment went further to give details on the essential elements required in the respiration in which it was found out that oxygen is essential for aerobic respiration, again glucose or some subtrates like starch must be present for respiration to take place. Carbon dioxide was released this was to confirm that it is of less essence for animals though in plants its used fro the process of photosynthesis .
Some environmental factors such as high temperatures and humidity affects the rate of respiration. In a very cold environment there is less activities experienced by the endotherms this result in utilization of less heat. When the requirement of heat energy is less in the body there is high likelihood of respiration process going slowly. Different food substrates effects differently on the process of respiration. For instance the starch is very rich in energy therefor when used it result in higher energy production. Respiration takes place in two stages in most ...Download file to see next pagesRead More

Should animal be used for scientific experiment

...somehow explain it researches believe that they have a right to decide for them. In this respect, animals without any choice become victims of experimentations, not even comprehending it. Confused and scared animals feel pain as much as we do. The only exception is that non-human creatures are not able to tell researchers about it, describing uncomfortable feelings and torments. So they have nobody to assist them or save from pain and the only way that they have got is to suffer silently until laboratories do not receive final results. Scientific experiments on animals show cruelty and callousness that should not take place in the human deeds. All in all people must realize that animals are their small brothers who do not have somebody...

Elevator Experiment

...?ELEVATOR EXPERIMENT The American society has a lot of formal and informal norms and assumptions for ridding in an elevator. The norms that are described as informal form the majority and they are the types that are not found in any books or constitution but are expected to be followed to the latter. Examples of these norms, some of which are verbal and others non-verbal include not starting a conversation that will last for over 15 seconds, facing the same direction as others and normally the front direction, not talking aloud in the elevator, not making eye contacts and exiting in order of who is closest to the door. These norms could be tagged as Emic distinctions rather than Etic because they have to do with the very people within...

Experiment Through the Use of the Scientific Method

...? An Experiment through the Use of Scientific Method Scientific method is very essential not only inside the laboratories but also in the daily existence. Conducting an experiment starts by observing a certain situation then identifying the problems from it. After identifying the problem, the observer can gather some data which can serve as a help upon formulating the hypothesis for the problem. If the pertinent information is enough, it is the time for the hypothesis to be formulated. Upon formulating the hypothesis, the observer can start to conduct his experiments and so, may accept or reject his hypothesis depending on the results of the experiment. Finally, he can now state how and why did the situation happen clearly...

Experiment # 3

...Experiment: Extra-Sensory Perception Hypothesis My hypothesis is that ESP does not exist. Procedures Three s were tested using two different types of Zener card tests. These tests were online, and can be found at www.scientificpsychic.com/esp/esptest.html and www.psychic-experiences.com/psychic-tests/zener-cards.php. Each was asked to perform the first test, of guessing the order of the cards, 10 times, and the second test, of guessing individual cards, 4 times. This gave a sample size of 200 chances per subject to guess or “sense” the correct Zener card. The subjects were informed in advance that the point of the experiment was to test their psychic powers or extra-sensory perceptive ability. After all three subjects completed the testing...

Breaching Experiment

...Introduction People’s personality is shaped according to the culture and social norms that they are brought up in. This makes it important to understand the role of social norms in shaping human behavior. Hence, an experiment was conducted to study what happens when someone tries to breach a social norm. This paper describes the result of the experiment. Experiment and reaction It is an acceptable practice for females to apply make-up. However, it is not an acceptable social norm for males to apply make-up while going out. I decided to breach the social norm by going out with a complete make-up applied on my face. On the day of the experiment, I borrowed the make-up kit from my female friend and applied the make-up. I applied face powder...

Experiment Convenience

...Experiment Convenience number Experiment Convenience I choose cornflakes for this assignment. I take cornflakes every day before going to school and I think I have some kind of special relationship with this product. What is this products “hedonics”? Once I bought the product my expectations were very high. Cornflakes are packed in a way that is able to attract the consumer purchasing the product. The product seems to be so easy to prepare and highly nutritious. The aroma is excellent and has a sweet taste. The texture is very soft once you mix the cornflakes with milk. However, without mixing with milk the texture is rough. What benefits does it provide for you? Cornflakes are low in sugars and calories. This means that cornflakes...

Scientific experiment

... al Affiliation Experiment on respiration process This experiment can be conducted at home. This is because the materials and methodology used are not complicated as it requires no lab technician. The materials used such as the beaker and lime water are available in the pharmacy such that the students can access them. This experiment was performed at home with an aim to demonstrate the proof for respiration in which carbon dioxide is given off, oxygen is consumed, and energy in the form of heat is released to the body. Respiration is an imperative process for plants and animals, its prominence is coming because it releases energy in terms of ATP to both the animals and plants. The experiment focused on the evidences which are considered...

Scientific method experiment

... Lecturer: The relative Weights of Gases Introduction Gases constitute a significant proportion of the world both quantitativelyand qualitatively. Just as possible as it is to establish the behavior of gases around us, it is also possible to establish the quantitative aspect of these gases. They have mass, pressure and volume just like other state of matters. It is a question of every scholar whether gases have definite mass. We often are left with question whether it is possible to establish the relative weights of gases. Gases have relative weights and this experiments aims at approving this hypothesis ( Pandey et.al. 56) To establish this, the experimentalist used four samples of five gases namely; Oxygen, Hydrogen, Carbon Dioxide...

...Recombinant DNA technology Recombinant DNA technology In obtaining the three plasmid DNA including A2-F, pFR-Luc, and Gal4, the study employed use of Luria broth and plasmid cloning techniques. Essentially, Luria broth defines a a bacteria culture media that with high nutrients used in laboratories. In addition, isolation of specific DNA sequences from complexes of varied sequences of DNA relates to DNA cloning (Walker and Rapley, 2009, p. 115). Plasmid or highly modified phage acts as vectors for replication of DNA fragment during cloning in a host cell. The inherent plasmid vector consists of three elements including cloning site, drug-resistance gene, and a replication origin (Stuttard and Rozee, 2013, p. 180). The latter... DNA technology ...

Experiment 2

... = buoyancy force, g = gravitational acceleration, and m = mass. On the other hand, Avogadro’s laws allows for the determination of a gas’ volume at a given density. Equation for Avogadro’s law is; molar mass/densitySTP = 22.415L/mole. By determining the volume and mass of any gas, it becomes easy to deduce a gas’ molar mass (Peck 68). This experiment involved determining the molar masses of hydrogen and helium; gases that are less dense than air. Experimental Procedures Prior to commencement of the experiment, appropriate safety requirements were performed. First, use of safety goggles and lab coats was prioritized. Secondly, water spilled on the floor was wiped in order to prevent slippage of students during the experiment. Finally, any...
