6 Cameron reads in his textbook that animal cells are composed of 90 percent water and 10
percent protein, carbohydrate, nucleic acid, lipid, and other molecules. He learns that
homeostasis is the process by which this composition is maintained. How does an organelle
in an animal cell control the content of water and other material in the cell?
F The cell wall splits apart to allow water and materials to enter the cell and waste
products to leave the cell.
G The cell membrane is selectively permeable, which controls the movement of materials
in and out of the cell by passive and active transport.
H Vacuoles in the cell open and draw in only the materials needed from outside the cell.
J
Lysosomes move out of the cell to capture and bring back needed materials.

Models of the human immunodeficiency virus (HIV) and an animal cell are shown below.

The cell membrane is selectively permeable, which controls the movement of materials in and out of the cell by passive and active transport.

Explanation:

According to this question, animal cells are made up of the following contents: 90% water and 10% protein, carbohydrates, nucleic acid, lipids and other molecules. The cell regulates this internal composition in a stable way via a process called HOMEOSTASIS.

The animal cell is able to regulate or maintain a stable internal composition by the possession of a selective permeable membrane called CELL MEMBRANE. The cell membrane is semi-permeable in the sense that it allows the entry of some molecules into and out of the cell and blocks others.

Some molecules are allowed by the cell membrane without the need for energy input in a transport called PASSIVE TRANSPORT while some requires energy input in a transport called ACTIVE TRANSPORT.

hi!

it would be because of the artist sixnine.

hope this !

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.
