Answer: D(nucleoid region)
Explanation:
In the diagram below the irregular shaped, supercoiled region, without a membrane, labelled D, surrounded by the cytoplasm of the cell is the nucleiod region that contains the main DNA in bacterial.
The nucleoid region in the prokaryotic cell contains the main DNA material. The nucleoid which means nucleus-like contains the main genetic material in prokaryotic cell, some satellite DNA are found in plasmid is other parts of the cell. Unlike the nucleus of eukaryotic cells the nucleiod lacks a cell membrane. The nucleiod has an irregular shape, and has a circular chromosome.
Relative humidity<span> (</span>RH<span>) is the ratio of the </span>partial pressure<span> of water vapor to the </span>equilibrium vapor pressure<span> of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. It requires less water vapor to attain high relative humidity at low temperatures; more water vapor is required to attain high relative humidity in warm or hot air.</span>
The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots.
