Answer:
A prokaryote is a cellular organism that lacks an envelope-enclosed nucleus. The word prokaryote comes from the Greek πρό and κάρυον. In the two-empire system arising from the work of Édouard Chatton, prokaryotes were classified within the empire Prokaryota.Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. Organisms that have eukaryotic cells include protozoa, fungi, plants and animals. These organisms are grouped into the biological domain Eukaryota.
Explanation:
The correct answer is: ensure that all tubes are attached to collection devices
An adequately functioning nasogastric (NG) tube should prevent nausea and vomiting because stomach contents are continuously being removed. Using the NG after abdominal surgery is a routine postoperative procedure until gastrointestinal tract starts to function properly. The patency of the tube should be checked together with the amount and character of gastric drainage.

trace fossils
Explanation:
Trace fossils are fossils that provide information about the biological activities and behaviors of past organisms.
Answer:
The correct answer is - virus, bacteria, protist.
Explanation:
Answer:
If a rock has a volume of 2 cm³ and a mass of 12 gr, its density will be 6 gr/cm³.
Explanation:
Density is a parameter used in chemistry and physics, which relates the mass and volume of a solid or compound, establishing the amount of volume that occupies a given mass.
If we observe the density formula, we can see that the greater the mass, the greater the density, while the volume is inversely proportional, so the lower the volume, the greater the density. This formula is:
ρ = m/V
Therefore, according to the mass and volume of the rock
ρ = 12 grs / 2 cm³
<em>ρ = 6 grs/cm³
</em>
Being the density of the rock equal to 6 gr/cm³.
