A. She turns around to go get her suitcase at point B, you can tell because the line decreases back to 0 then starts again.
B. She waits at the railroad tracks from points D-E for 5 minutes. At these points her distance remains constant, she is not moving.
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.
In 1940 Matthew and Marion Stirling found basalt altars at the site of La Venta.
Matthew Stirling was an ethnologist and archaeologist that was sent on expeditions to the Mexican Gulf Coast area to further research the <span>Olmec culture. It was in then years around 1940 that he found with his wife, Marion, several sculptures and monuments in that area. In 1940 he found several altars in La Venta.</span>
