How are cardiovascular and respiratory system related?
The cardiovascular and the respiratory system both work toward the same goal: getting oxygen to tissues and getting carbon dioxide out. The respiratory system is involved in supplying oxygen to the blood and removing carbon dioxide. When the heart receives blood that is low in oxygen and high in carbon dioxide, it pumps it to the lungs via the pulmonary arteries. When the lungs expand and get fresh air from the environment, oxygen is transferred (via the alveoli) into the low-oxygen blood, which also then sends some of its carbon dioxide back into the lungs. Now that this blood has fresh oxygen in it, it returns to the heart and the heart then pumps it throughout the body.
What gas is being taken up when the marker on the inside arm of a respirometer moves toward a tube that contains germinating seeds?
Oxygen is being taken up by the germinating seeds in the respirometer. As the seeds undergo cellular respiration, they consume oxygen and release carbon dioxide, causing the volume of gas in the respirometer to decrease and the marker to move.
How does carbon dioxide in the atmosphere affect earth's climate?
Carbon Dioxide is a part of the cycle of plant and animal life. Carbon Dioxide is used by plants to manufacture sugars and the plants then give off oxygen as a byproduct. Animals such as people can breathe that oxygen in the air and change it back to carbon dioxide while metabolizing food. Other processes such as fire and rot also can produce carbon dioxide using the oxygen in the air. Burning of fossil fuels also reduces atmospheric oxygen and produces carbon dioxide. Carbon dioxide also affects the radiation budget of the earth. That is the amount of heat that is absorbed balanced against the amount of heat radiated. Carbon Dioxide in the atmosphere tends to serve as a blanket that allows the high frequency energy radiations from the sun in toward the earth. When these high frequency radiations strike the earth, they produce heat that then may be dissipated as infra-red radiation. But carbon dioxide tends to reflect infra-red radiation and increases the overall heat of the earth. Carbon dioxide also dissolves in cold water and some is absorbed into the world oceans.
What is the molecular structure of ccl2o what type of bond is it?
The Lewis Structure of CCl2O is:1. Carbon atom in the middle2. Oxygen will form a double bond with Carbon and has 4 unshared electrons3. Both Chlorine atoms will form a single bond with Carbon and have 6 unshared electronsThe Formal Charge on each atom is 0 which means that this structure contributes the most to resonance.The VSEPR structure for this molecule is trigonal (triangular) planar and is polar with the more negative charge tending toward the Oxygen (more electronegative)
The four single bonds of a carbon atom are directed in space toward the corners of what?
The four single bonds of a carbon atom are directed in space toward the corners of a tetrahedron. This arrangement ensures that the bonds are as far apart from each other as possible, minimizing repulsion between electron pairs and maximizing stability of the molecule.
How does exchange of nutrients and oxygen with waste and carbon dioxide take place in the capillaries?
Pure diffusion ... everything flows from high concentration toward low. No energy is expended in these exchanges.

How are the cardiovascular and respiratory systems integrated?
The respiratory system draws oxygen into the lungs where the circulatory system exchanges waste gas (carbon dioxide) for oxygen. The respiratory system then expels the waste gas during exhalation, and the circulatory system delivers oxygen to cells throughout the body.
What system does the respiratory system relate to?
The cardiovascular and the respiratory system both work toward the same goal, getting oxygen to tissues and getting carbon dioxide out. The respiratory system is involved in giving oxygen to the blood and removing all the co2 . When the heart receives blood that is low in oxygen and high in carbon dioxide, it pumps it to the lungs. When the lungs get bigger and get air from the environment, oxygen is transferred into the blood with the low-oxygen , and some of the co2 comes back into the lungs. Now that this blood has good oxygen in it, it returns to the heart and the heart then pumps it throughout the body.
What is a leech's breathing organ?
Leeches do not have a separate respiratory system. They absorb oxygen through their cuticle (skin) and it diffuses throughout the leech's body. Carbon dioxide leaves via the same route - diffusion toward the cuticle where it will diffuse out.

Is Oxygen more polar than nitrogen and carbon?
Yes, oxygen is more polar than nitrogen and carbon because of its higher electronegativity. Oxygen has a greater ability to attract electrons toward itself, resulting in a greater difference in electronegativity and thus a more polar molecule.
What do you have to do to get more carbon dioxide to a plant?
Assuming that the plant has enough sunlight and is only being limited by low carbon dioxide, you can increase the local partial pressure of the gas, typically by having a number of people stand around and exhale toward it. Greenhouses have lower levels of carbon dioxide than outside air, but usually more than enough for the plants to perform photosynthesis.
What substances flow through the right atrium?
The right atrium receives "de-oxygenated" blood (blood from the body containing less oxygen and more carbon dioxide) and the right ventricle sends this blood toward the lungs.
