According to the uid-mosaic model of the plasma membrane Select one: a. Phospholipids form a double layer, with the hydrophilic heads facing each other in the center. B. The membrane is a rigid structure. c. Proteins are free to move within a double layer of phospholipids. d. Protein and phospholipids form a regular, repeating structure.

c. Proteins are free to move within a double layer of phospholipids.

Explanation:

According to the fluid mosaic model, proteins and phospholipids can move laterally and rotate in their place. This is one of the characteristics of the fluid mosaic model. The fluidity of the membrane's components depends on factors such as temperature, the presence of cholesterol, and if the fatty acid chains of the phospholipids are saturated or not.

answer:

its probable on the floor if it fell off.

answer: no, they are not.*

although rubber bands that contain excessive amounts of dye, toxins, or additives are sometimes toxic, most rubber bands do not cause any health issues. since they are typically made of latex, (a natural substance that is extracted from trees) they are not dangerous in any way if you chew them or accidentally ingest a piece of rubber band. however, chewing rubber bands does pose a choking hazard and is not a good habit to have.

*depending on the type of rubber band. the typical rubber bands that you see at stores are not toxic, but other types of rubber or latex that contains certain chemicals may be unhealthy and hazardous.
