cytoplasm
the fluid part of the cell is called the ______
the part of the cell that regulates substances into and out of the cell is called the ______
the part of the cell that contains chromosomes is called the ______

Explanation:

First Blank (The fluid part of the cell...):

The cytoplasm is the fluid - like substance within the cell (excluding the nucleus in eukaryotic cells) where many cellular processes occur. Among the given options, cytoplasm matches the description of the fluid part of the cell.

The plasma membrane (also known as the cell membrane) is a selectively permeable barrier. It controls the movement of substances, such as nutrients and waste products, into and out of the cell. So it is the structure that regulates what enters and exits the cell.

The nucleus is the control center of the cell. It houses the cell's genetic material in the form of chromosomes (which are made of DNA and proteins). So the nucleus is the structure that contains chromosomes.

Answer:

cytoplasm
