inessss [21]

Answer:

Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field.

Since blood cells are not typically found in lymphatic vessels, the vessel in question can be assumed to be a vein.

More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself.
