The correct answer is - They supply the energy needed for living processes.
Both the carbon and the nitrogen, are gases that are crucial for the survival of the organisms on the planet. They are mostly used by the producers in the ecosystems, as they need them to manage to perform their cycles, get nutrition, and of course energy. The producers are the basis of the ecosystems, so if they do not have a healthy supply of carbon and nitrogen, the ecosystems on the whole planet will collapse. The carbon and the nitrogen later go from one organism to another as the energy is transferred, and usually end up back into the atmosphere again.
The Punctuated Equilibrium theory proposes that a specie that appears in the fossil record will become stable. To support this theory, a fossil record serves as an evidence which includes transitional fossils. Transitional fossils refers to the remains of an organism that still exhibit traits to both the ancestral and descendant group.
<span>Proteins secreted by epithelial cells. The basement membrane forms as a thin protein fibre membrane with mucopolysaccharides. It separates an epithelium from underlying tissue. Its main function is to anchor epithelium to dermis underneath. The membrane consists of different extracellular matrix structural proteins.</span>
Homan's Test is an
examination procedure of the ankle to test for dorsiflexion, which signals thromboembolism.
This is done by putting patient in supine position with leg straight, and then
raising the leg 10 degrees. The examiner will then dorsiflex the foot and
squeeze the calf. Pain in the calf upon flexion of the ankle with the leg
straight means a positive Homan's sign.
