Answer:
Because most natural environments harbor a stunningly diverse collection of microbial species. Within these communities, bacteria compete with their neighbors for space and resources. Laboratory experiments with pure and mixed cultures have revealed many active mechanisms by which bacteria can impair or kill other microbes. Additionally, a growing body of theoretical and experimental population studies indicate that the interactions within and between bacterial species can profoundly impact the outcome of competition in nature. The next challenge is to integrate the findings of these laboratory and theoretical studies, and to evaluate the predictions they generate in more natural settings.
Explanation:
Answer is membrane protein
Plasma membrane or cell membrane is made of lipoprotein (lipid and protein). The structure of the plasma membrane is based on the fluid mosaic model which gives basic description of the structure and behavior of membranes. The plasma membrane is a mosaic of phospholipids, cholesterol and proteins. Many proteins can move within the plasma membrane through membrane diffusion. The membrane proteins regulates the coming and going of substances into and out of the cell.
