Many organisms use energy to perform their cellular functions. That energy comes from the energy that is stored in food then converted to adenosine triphosphate or ATP. ATP can be obtained with or without oxygen, aerobic respiration and anaerobic respiration. Aerobic respiration produces carbon dioxide (CO2) as a by-product while anaerobic respiration produces Ethanol (C2H6O) or Lactic acid (C3H6O3). In aerobic respiration the “CO2 produced during cellular respiration can combine with water to produce carbonic acid.” While CO2 is produced, the amount of CO2 produced is different depending on the organisms, in this case crayfish. To test the changes in pH, NaOH is used to neutralize the carbonic acid produced by the crayfish, by which the
The authors exposed seedlings to two different Carbon dioxide levels, soil temperature, and light conditions for one growing season. The two Carbon dioxide levels were 392 µ to a 784 µ , the two soil temperature was 17 and 22 degrees Celsius, and the two light conditions were 100% and 30% of the original 100%.
From the data obtained in Tables 1-3, we were able to plot multiple graphs using excel. These graphs give a better representation of the data as seen in Figures 1-9. It can be seen that each figure shows a slight increase in CO2 production, which signifies a possible change in metabolic rate. Figures 4 and 7 show a relatively large change between the control and fox urine. The changes in slope between theses two are 0.0267 for Figure 4’s slopes and 0.0192 for Figure 7’s slopes. Figures 1-3, 5-6, and 8-9 all showed a change, but not as large as their counterparts. This was due to the fact that the mice were usually cleaning themselves at in this group during the control. Figure 8 shows the smallest change between the two groups with a value of 0.0002. This figure represents a Cage A Yellow Mouse, which also had one of the lower body weights.
“Children learn more from what you are than what you teach” (W.E.B DuBois). Children constantly gain knowledge from their parent’s actions and decisions. Mexican Whiteboy by Matt de la Peña, The Bean Trees by Barbara Kingsolver, and Two Kinds by Amy Tan all show different ways parents influence their child’s behavior and decisions. Throughout these three novels, parents are role models for their children through the examples they set, the way they treat them, and how they force them into situations. A child’s actions reflects the influence from their parents because they want to make their parents proud.
We accept our hypothesis of the germinated seeds in the dark and the dormant seeds in the dark having a higher rate of cellular respiration then germinated seeds in the light and the dormant seeds in the light. The germinated seeds in the dark had 0mL of change in oxygen levels while the germinated seeds in the light had -.05mL of change in their oxygen levels. The germinated seeds in the dark had a .05mL more for their change in oxygen then the germinated seeds in the light, therefore the germinated seeds in the dark had a higher rate of cellular respiration then the germinated seeds in the light. The dormant seeds in the dark had 0mL of change in their oxygen levels and the dormant seeds in the light had -.16mL of change in their oxygen levels. The dormant seeds in the dark had a .16mL greater change in their
The aim of this experiment was to investigate how the presence of light affects the rate of transpiration in plants.
At 9:15am the students finished circle time and were sitting in their seats waiting for their snack to be served. As the assistant was giving lunch boxes to the students the teacher told the class about an experiment they were going to do. She told them they were going to
Plants are the most amazing environmental species, that have been around for millions of years. Most plants live from water and the sun’s energy, but some plants can tolerate saltwater. Two articles will be using charts, graphs, and pictures to find out which plants can tolerate saltwater. In the end only some plants with survive, while other will perish from this experiment.
In this task I will be researching the effect that acid rain has on the rate of plant growth. Acid rain is any type of precipitation with a high pH, with high levels of nitric acids. The reason why I had chosen this topic was because acid rain seems to have a great effect on the effect of plant growth, and plants play a very important role in our ecosystem. Acid rain is a major problem in our environment when we are not able to neutralize the acidity.
Salinity describes soils that contain high concentrations of water-soluble salts, mainly NaCl. Salinity is usually caused by two mechanisms: groundwater salinity and irrigation salinity. Groundwater salinity occurs when saline groundwater is present in the upper layers of the soil. This commonly occurs in areas where native vegetation has been cleared and evaporation rates are high, like the West Australian wheat belt. Irrigation salinity occurs when irrigation water accumulates in the upper layers of soil. When this water evaporates, the salts remain in the soil. Irrigation salinity is common in areas where soil drainage is poor and low quality water is used for irrigation (Rengasamy, 2006).
Which one has a higher rate or respiration between dicotyledonous (peas) and monocotyledonous (maize) seeds and what is the effect of temperatures (room temperature, 40, 60) on the rate of respiration as determined by oxygen usage estimated with a respirometer?
Their was a correlation to the size of the bean and its life span. The smaller beans lasted longer and grew in population, compared to the larger ones that decayed in population. The reasoning for this is that the size of the bean affects how easy it is to pick up. This is shown in the table, the kidney beans the largest beans only lasted two generations, while the lentils the smallest beans finished with the largest population. Another factor was the texture of the beans. The smooth beans population began to decay after generations, the rough beans had growth in population after time. This also relates to the ability to pick up the beans, rough would be harder and take longer to pick up. This is show as the two of the three groups of smooth beans went extinct, while the two rough sets of beans finished with the densest populations. Another aspect that affected the survival of the beans was the color of the
Plants are a major necessity in the balance of nature, people’s lives, and our terrain. We may not realize it, but plants are the ultimate source of food for almost 95% of the world population so says the National Group of Food. It’s a fact that over 7,000 species of plants are being consumed today.
