How are the carbon, nitrogen and oxygen cycles similar
Sever21 [200]

Answer:

Firstly, they are all biogeochemical cycles. They cycle substances through the different systems. So this means that these substances like elements, compounds, and the like go through the hydrosphere, atmosphere, geosphere, and biosphere. It involves both the living and non-living things on Earth, all playing a role in transforming substances into something that can be used, only to be recycled again to provide for the other in a cyclic manner.

For example the oxygen cycle involves how oxygen is produced and used over and over. As we exhale Carbon Dioxide, it gets absorbed by plants which use it, along with water and light, to produce their own food in a process called photosynthesis. A by-product of this process is oxygen which we take in and use and we exhale Carbon dioxide again.

Compare the structure of the left atrioventricular valve with that of the aortic valve ​
Zepler [3.9K]

The left atrioventricular valve is structurally different from the aortic valve in the following ways.:

The Left atrioventricular valve is bicuspid valve while the Aortic valve is the semilunar valve.

The Left atrioventricular valve has irregular leaflets that regulate the opening and closing of the atrioventricular orifice, while the aortic valve has cusps like structure folded like half moon shaped structure.

Specialized supporting structures are needed to support the AV valve to the heart while the semilunar shape of aortic valve is self supportive.

Explanation:

Atrioventricular valves maintain the unidirectional flow of blood from atria to ventricles while the aortic valve maintains unidirectional flow of blood from left ventricle to the aorta.
