what do we call the three categories that divide living organisms based on their genetic links?
o domains
trabhic levels
o kingdoms
o genetics

Domains

Explanation:

Living organisms are divided into three domains:

Archaea

Eubacteria

Eukarya

Organisms are divided into these three domains based on genetic similarities or closeness. Archaea and Eubacteria are domains that consist of prokaryotes or prokaryotic cells.

Prokaryotes in the domain Archaea differ from those in Eubacteria because of certain characteristics like their ability to live in extreme environments and the absence of the peptiglycan in their cell walls.

Prokaryotes in the Eubacteria domain have peptidoglycan walls and RNA unique to them.

Organisms uner Eukarya, as the name suggests, have eukaryotic cells meaning the have an enclosed or membrane-bound nucleus.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

explanation:

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
