Answer:
To begin, in direct relation to plasma membranes, we have the fluid mosaic model, explanation for various observations related to the structure of cell membranes. In this model, there is a lipid bilayer where protein molecules are fixed. The lipid bilayer allows the membrane to achieve elasticity. This model of the cell membrane is how scientists view the functions and parts of the cell membrane. The fluid mosaic model can also serve as an explanation for the phospholipids, cholesterol, proteins, and carbohydrates that make up the membrane. Before delving into the fluid mosaic model, one must first fully understand plasma membranes and the role that they play. The plasma membrane is the membrane in all cells that protects it from the outside environment. The plasma membrane controls materials that come and go from the cell. The membrane is mainly formed of amphiphilic or dual-loving, phospholipid molecules. The hydrophilic part of these molecules is in constant contact with the fluid inside of and surrounding the cell. The phospholipid molecule is made of a three-carbon glycerol base with two fatty acid molecules attached to two of the carbons, and a phosphate-containing group attached to the third one. This arrangement results in a polar charge. The membrane surfaces that face the inside and outside of the cell are hydrophilic. In opposition, the middle of the cell membrane is hydrophobic. Therefore, phospholipids form an effective lipid bilayer cell membrane that divides fluid within the cell from the liquid outside of the cell. In conclusion, fluid mosaic is used by scientists to view the parts of the cell membrane, which has a lot of components that render it non-permeable. (phospholipids, integral protein, peripheral protein, cholesterol, glycoproteins/lipids.)

Idk if this is right but hopefully it helps.
I would say the answer is A I really hope this helps! :)
The organism which is multicellular and that it first digests, then absorbs nutrients from the environment around it, best fits into the classification of fungi.
Multicellular organisms are those that are comprised of more than one cell in their body. They can either have a loose composition of various cells or have a complete organ-system kind of body. The example include all animals and plants.
Fungi is the kingdom consisting of multicellular eukaryotic organisms. The mode of nutrition in fungi is heterotrophic. It can be of various types like holozoic, saprophytic and parasitic. However the saprophytic mode is more predominant.
