The cell membrane controls the passage of substances into and out of the cell. It is a selectively permeable barrier made up of a phospholipid bilayer with proteins embedded in it. It allows some material (such as steroid hormones) to pass straight through, while others (such as ions) need the assistance of a protein transporter, and some material cannot get in at all.
Which structure contains a eukaryotic cells genetic material
The ring of muscle that controls the passage of material from the stomach into the small intestine.
All cells have a cell membrane that encloses the cell and controls the passage of substances in and out of the cell. They also contain genetic material in the form of DNA that carries the instructions for cell functions. Additionally, cells have the ability to produce energy, often through the process of cellular respiration.
DNA, found in the nucleus.
The nucleus controls the cells activities

The structure in eukaryotic cells that controls cell activities and contains genetic material is the nucleus. It houses the cell's DNA and is responsible for regulating gene expression and coordinating cellular functions.
They are variable controls which can open to allow the passage of material and then closed to prevent further passage of materials. If you didn't have an anal sphincter you'd really have problems.
In your cells' nucleus.
The Nucleus
The cell membrane is the structure found in both plant and animal cells that controls the passage of substances into and out of cells. It is a selectively permeable barrier that regulates the movement of molecules such as nutrients, ions, and waste products.
All cells have a cell membrane that encloses the cell and controls the passage of molecules in and out. They also contain genetic material in the form of DNA that carries instructions for the cell's functions. Additionally, all cells have ribosomes, which are responsible for protein synthesis.
