Answer:
10%
Explanation:
Chargaff postulated the complementary base pairing rule, where he stated that in the DNA molecule, Adenine (A) will always pair with Thymine (T) and Guanine (G) with Cytosine (C) i.e. A-T, G-C
Chargaff stated that the concentration of purines (Adenine and Guanine) is always equal to that of pyrimidines (Thymine and Cytosine) i.e. {A} + {G} = {C} + {T}
These equal concentration equals 100% in totality i.e. A+G+C+T= 100%
Thymine pairs with Adenine, if there is 40% of Thymine in the DNA molecule, it means there will be 40% of Adenine also. 40 + 40 = 80%. This leaves us with 100-80 = 20% for Guanine and Cytosine.
Since there will be an equal amount of Guanine and Cytosine too, Guanine will therefore, be 20/2 = 10%.
That is, 10% Guanine, 10% Cytosine.
Carbon cycles from the atmosphere into plants and living things. For example, carbon is a pollutant in the atmosphere as carbon dioxide.
...
Photosynthesis. Plants pull in carbon dioxide out of the air through photosynthesis. ...
Decomposition. ...
Respiration. ...
Combustion.
I hope that this one is correct - C
Since transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.
<span>Stomach. Stomach which connects oesophagus to small intestine is the main part of digestive system where digestion occurs. Protein is a necessary food content for the healthy being of body. From the food proteins are liberated and its chemical digestion starts in the stomach.</span>
Answer:
respiratory system
Explanation:
The bronchi become smaller the closer they get to the lung tissue and are then considered bronchioles. These passageways then evolve into tiny air sacs called alveoli, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
