Ascientist discovered a microscope, unicellular organism with no nucleus. which of the following correctly describes the organism? 1. the organism is a plant. 2. the organism is an animal. 3. the organism is a prokaryote. 4. the organism is a eukaryote.

The correct answer is 3. The organism is a prokaryote.

Explanation:

Cells that are the basic unit for life are classified into eukaryotic or prokaryotic. In the case of prokaryotic cells, these differ from eukaryotic cells because they do not have a defined nucleus or bounded organelles; instead, ADN and similar are located in the cytoplasm.

Additionally, prokaryotic cells occur only in unicellular organisms such as bacteria or archaea, while other types of organisms such as plants, fungus or animals are composed of eukaryotic cells. This implies if the scientist discovered a microscope, unicellular organism with no nucleus, the organism is a prokaryote organism as this is these are the main features of prokaryotic cells or organisms.

the species living around the vents are especially good at dispersal.  

deep-sea vent originates on the floor of the ocean when seawater circulates through hot volcanic rocks, usually situated where the new oceanic crust is being produced.  

biological dispersal refers to the movement of species from their location of birth to their site of breeding, or from breeding site to another. similarly, the oceanic dispersal refers to the movement of the species from one land mass to another by sea crossing.
