The ocean is a carbon sink, with carbon being utilized by photosynthesis of phytoplankton describes the availability of carbon in the ocean and its use by marine processes
The ocean is a carbon sink, with carbon being utilized by photosynthesis of phytoplankton.
<u>Explanation:</u>
The carbon is found in the ocean is utilized by the phytoplankton found in the ocean. The carbon sinks in the ocean and then the process of photosynthesis required the carbon dioxide and the sunlight.
The ocean plays an important role in the carbon cycle, the carbon spreads in the ocean are called the ocean sink because it takes up more carbon from the atmosphere. The chemical and biological processes influence the carbon by producing more carbon dioxide in the atmosphere.

Answer:
Chemically gated Na+-K+ channels
Explanation:
The acetylcholine receptors are the receptors or ion channel proteins which are considered the transmembrane proteins. The acetylcholine receptors are of two types depending on the ligand which binds that is either nicotinic or either muscarinic receptors.
When the acetylcholine binds the receptor molecule, the ion channels open up and allows the passage of the sodium and potassium ios which depolarizes the membrane potential and generates the action potential in the neuron.
Thus, Chemically gated Na+-K+ channels is correct.
