Answer:
trophic level
Explanation:
Each step of the food chain in the energy pyramid is called a trophic level.
B) It is a fluid mosaic model, with proteins interspaced in the phospholipids, both of which can freely move laterally.
Explanation:
The fluid mosaic model proposed by Singer and Nicolson describes the plasma membrane’s structure as a mosaic pattern of components consisting of phospholipids, proteins, cholesterol, and carbohydrates; all of which provides the unique fluid character of the membrane.
According to this model, the phospholipids constitute the main fabric, cholesterol attaches between the phospholipids in between the layers, integral proteins embedded within the bilayers of the phospholipids, peripheral proteins along the peripheries of the layers and carbohydrates outside the membranous layers.
Answer:
Addition polymerization is a polymerization process that produces addition polymers. Addition polymers is a polymer that is formed by connecting or addition of the monomer units by a carbon-carbon bond without the use of other chemicals or without co-generation of other products.
It is different then condensation polymerization that co-generates other products or used other reactant chemicals. Polyyethene and polypropene are the examples of addition polymers.
