What is the role of oceans in the carbon cycle?
Maslowich

Answer:

Don't worry I'm here to help

Explanation:

The ocean plays an important part in the carbon cycle.

  • Overall, the ocean is called a carbon 'sink' because it takes up more carbon from the atmosphere than it gives up.
  • Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter.

Glad I could help!!

When THC binds to its receptor, how are the levels of cAMP affected in the post synaptic cells?
Nadya [2.5K]

Cannabinoid receptors, located throughout the body, are part of the Endocannabinoid system which is involved in a variety of physiological processes including appetite, pain-sensation, mood, and memory.[1]

Cannabinoid receptors are of a class of cell membrane receptors under the G protein-coupled receptor superfamily. As is typical of G protein-coupled receptors, the cannabinoid receptors contain seven transmembrane spanning domains.[5] Cannabinoid receptors are activated by three major groups of ligands: endocannabinoids, produced by the mammillary body; plant cannabinoids (such as Cannabidiol, produced by the cannabis plant); and synthetic cannabinoids (such as HU-210). All of the endocannabinoids and plant cannabinoids are lipophilic, such as fat soluble compounds.
