The majority of bacteria have a cell envelope component which serves as an outer compartment. 
Explain the Plasma membrane components.
The membrane that divides the interior of the cell from the external environment is known as the plasma membrane, sometimes known as the cell membrane, and is present in all cells. 
A cell wall is affixed to the plasma membrane on the exterior of bacterial and plant cells. A semipermeable lipid bilayer makes up the plasma membrane. The movement of materials into and out of the cell is controlled by the plasma membrane.
A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it offers a stable environment inside the cell. And that membrane serves a variety of purposes. One is to move compounds out of the cell that is harmful as well as nutrients into the cell.
Hence, the correct answer is the outer membrane.

<span>The correct option is C. Erosion is the process by which the earth surface get worn down. It involves the removal of soil, rocks or dissolved material from one location and its transportation to another location. Erosion can be caused by water, wind and glacier.</span>
        
                    
             
        
        
        
Human monoclonal antibody (mAbs) are emerging in the field of cancer therapy and have become an increasing proportion of new drugs that are recently approved. Although there are some methods to obtain antigen-specific mAbs from human B cells, it is generally impossible to directly immunize human beings with antigens of interest. For example, for infectious agents, those approaches are largely restricted. To solve these obstacles, two main approaches have been developed; either by humanizing antigen-specific antibodies from small experimental animals (which is laborious due to the great genetic differences from humans) or rely on the in vitro selection of antigen-specific binders from human antibody repertoires. However, the human mAbs developed by these methods are usually with low affinity.
We are now coming up with a much better idea that is humanizing non-human primates mAbs instead of murine mAbs. Due to the close genetic relationship with humans, immunized NHPs have more potential to be isolated with high affinity antibody to human target than other experimental species, such as mouse, rat and rabbit. In addition, with appropriate method, NHP antibodies are much<span> easier to be humanized</span> without any loss of affinity compared to widely used murine antibodies.
