the chromosomal hereditary material is packaged in this organelle in eukaryotic cells but not in prokaryoitc cells. This organelle is called

Nucleus

Explanation:

The correct answer would be the nucleus.

The nucleus is a double membrane organelle that is found in all eukaryotic cells but not in prokaryotic cells. It contains the chromosomal hereditary material of eukaryotic cells and serves as the control center of the cell where other cellular activities are dictated.

The chromosomal hereditary materials of prokaryotic cells lie freely within the cytoplasm unlike what is obtainable in eukaryotic cells. The materials are package in a condensed fashion within the eukaryotic nucleus to form a structure known as chromatin. During cell division, the chromatin decondenses and become visible under the microscope as chromosomes.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
