Which type of protein stays only on the surface of the plasma membrane

Peripheral membrane proteins

Explanation: Hi, the Peripheral membrane is a Protein that is physically associated with a membrane, via interactions with lipid headgroups at the membrane surface or with another membrane protein. Peripheral membrane proteins are typically bound to the membrane surface, but may dip slightly into the lipid bilayer.  

Peripheral membrane proteins can form a multitude of higher-order structures due to membrane-mediated interactions.  

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
