Explain Why The Methylene Blue Dye Only Moved 4 Millimeters

The two body organ systems involved in gas exchange are the respiratory and cardiovascular systems. O2 and CO2 cross the cell membrane via simple diffusion. Because cells all throughout the body require oxygen and the removal of carbon dioxide, this simple method of diffusion is the best way to transport such small molecules over a large area as efficiently as possible.

However, this is inconsistent with what we have been taught and with what is written in the textbook. Since the textbook is a more reliable source of information, I must conclude that the reason for this difference in results may be attributed to error on the part of the students conducting the experiment.

The dialysis bag experiment resulted with beaker one having relatively similar numbers, showing as an isotonic medium. Beaker two’s solution gradually increased within an hour which caused the product to

Transportation has many roles in the cardiovascular system. First, our blood carries oxygen from our lungs to all of our tissues. While taking oxygen to our tissues, it also picks up carbon dioxide from them and takes it to our lungs to be removed from our body. Second, it delivers nutrients from our digestive tract to all of our body’s tissues. Third, it takes waste to our kidney’s to be removed from our body. Fourth, it

The same happens with Carbon Dioxide (CO2). The blood in the surrounding capillaries has a higher concentration of CO2 than the inspired air due to it being a waste product of energy production. This is when O2 and CO2 pass each other going back around the body systems to the heart. Once this is done the flow goes from Deoxygenated blood to Oxygenated blood.

One of these errors could have possibly been that the solutions were left uncovered during the testing phase. An uncovered solution can be contaminated with certain particles of elements found in the air that settle in the solutions, creating colors that are not are not linked with that specific element. This can be compensated for by covering the solutions with a lid prior to testing, in order to limit exposure to any outside factors.

For part one of this experiment, I only experienced separation of colors with the green and brown M&M’s, along with the yellow food coloring. The green M&M separated into yellow and blue, with blue travelling farther up the paper. It is not surprising that green separated into blue and yellow because those are the primary colors that make up green. The brown M&M separated into red and orange, with the orange travelling farther up the paper. Finally, the yellow food coloring separated into yellow and red, with yellow travelling farther up the paper. This could be because it was such a concentrated, small amount of food coloring. The colors that didn’t travel very far up the paper, such as orange and brown, are probably less soluble than the others, like blue and green.

This is when the water molecules come from a higher concentration within the body and they then transfer into a region of low concentration, this happens through the partially permeable membranes within the

Answer 2: The respiratory system functions in the exchange of gases with the outside environment. Oxygen is inhaled through the nasal cavity or the mouth, and it travels to the alveoli in the lungs. There, the capillaries exchange the oxygen for carbon dioxide. The oxygenated blood flows back to the heart from the lungs. It enters the left side of the heart and is delivered to all the body tissues via the aorta. In the capillaries of the body tissues, oxygen is exchanged for carbon dioxide. This deoxygenated blood flows back to the right side of the heart and then to the lung. In the capillaries that run across the alveoli, carbon dioxide is exchanged for oxygen that has recently been inhaled. The carbon dioxide will then be exhaled through the mouth and nasal cavity.

The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).

After all of that the oxygen enters our bloodstream by diffusing through the membranes of the lungs and then into the blood vessels. This is then passed onto another system which is The Circulatory System; this system then transports the oxygen to all of the cells in the body and picks up any waste products on the way.

In this graph you can see the error bars (using standard dieviation) are overlaping at every point except at the outliner which was at 2.5% dye concentration with 20% azide. Note how all the solutions (control, 10% azide, 20% azide, and 30% azide) show

Although the experiment was as fair as it could have been, there were some factors that were beyond our control. Firstly, the tubers that we used may not have been from the same specimen,

The purpose of this lab was to discover which molecules are found in certain foods. I expected to learn more about the molecules that we tested for, which were simple sugar, starch, and protein. I also expected to learn more about macromolecules, since simple sugar and starch are both carbohydrates, and I expected to learn more about what makes up food. If each food is tested for simple sugar, starch, and protein, then milk will have simple sugars and protein, crackers will have simple sugars, bananas will have starch and simple sugars, and egg whiles will have protein.

Within the alveoli, the oxygen is transferred to the blood whilst simultaneously collecting waste carbon dioxide for excretion as we breath out. This transference is known as diffusion and is linked to the cardiovascular system.
