Question: Molecules on the surface of cells is?
Answer: <u>Molecules on the surface of cells is: Cell surface receptors (membrane receptors, trans-membrane receptors) are receptors that are embedded in the plasma membrane of cells. They act in cell signaling by receiving (binding to) extracellular molecules.Cell surface receptors (membrane receptors, trans-membrane receptors) are receptors that are embedded in the plasma membrane of cells.

Answer:
stem cells
Explanation:
Stem cells differ from other kinds of cells in the body. All stem cells—regardless of their source—have three general properties: they are capable of dividing and renewing themselves for long periods; they are unspecialized; and they can give rise to specialized cell types.
Answer:
Bacteria/Microbes
Explanation:
Many organisms that live deep in the ocean feed off of bacteria and microbes near heated vents and volcanic areas.
Answer:
The coastal upwelling and changes in wind and water circulation patterns is the main natural cause of dead zones.
Fertilizers cause hypoxia due to the over growth of algae on the surface of water bodies.
Explanation:
Coastal upwelling is the cause of dead zones in which water that is present in depth comes to the surface of ocean due to the movement of water because of wind. Fertilizers cause hypoxia due to the over growth of algae on the surface of water bodies. The fertilizers increases the algal growth by providing nutrients necessary for its growth. This over growth decreases oxygen concentration in water and affect marine organisms.
