A means of water erosion would not be C. natural water springs. Erosion occurs when water or wind removes rock, dissolved material, and soil from one location to another. All the other options describe water moving from one location to another, which accurately describes what erosion does.
Ionic bonds result when electrons are tranfered between atoms. Covalent bonds result when valence electrons are shared between atoms. You should be able to identify whether an ionic or covalent bond is being formed between atoms.
Mold and mushrooms are both fungi, the mold is called “Hyphomycetes”
After the adenylyl cyclase reaction (which convert ATP into cyclic adenosine monophosphate-cAMP), cAMP level is directly increased. Next steps of PKA activation include:
• cAMP binding to regulatory subunits of PKA, as a result conformational change in the regulatory subunits of PKA is induced,
• catalytic subunits are detached and unleashed by regulatory subunits and as a result activated.
