A researcher in a lab finds a microscopic organism that is a producer. Populations of this organism are found in extreme environments (e. g., hot springs). The researcher will correctly identify this organism as belonging to the domain .

Archaea

Explanation:

Archaea is domain of living organism consisting of unicellular, prokaryotic organisms that are able to exist in extremely harsh environment such as hydro-thermal vents, hotsprings and acidic environment.

Some archaea are known to posses the capacity to carry out a form of photosynthesis using rhodopsin-like ion pumps to move ions against the gradient and produce ATP via chemiosmosis. However, no known archea has the ability to carry out classical photosynthesis like that of green plants.

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells
