Answer:
Water acts a carrier of food and oxygen to their body and it also carries out waste material and carbon dioxide from the body. In simple multicellular organisms like Hydra, the transportation of material from cell to cell takes place through simple diffusion.
The cell membrane is a biological membrane that surrounds (protects) a cell and separates the contents of the cell from its surrounding environment. The chemical structure that makes up the cell membrane include; phospholipids (lipid molecules that contains a phosphate group head and two fatty acid tails), glycolipids (lipids with carbohydrate), proteins and cholesterol. The phospholipids forms a double layered membrane around the cell.

Answer:
Plants absorb nutrients and water and and is anchored through their roots
Explanation:
The roots absorb water and minerals from the soil and anchor the plant in the ground. The stem supports the plant above ground, and carries the water and minerals to the leaves. The leaves collect energy from the Sun and make food for the plant, using an amazing process called photosynthesis.
A nested selection structure can appear in either an outer selection structure's true path or its false path.
