Based on the organization of plants and animals at a cellular level, the following is true:
- 1) Membrane protein complexes that strengthen the adhesion between adjacent cells, like rivets, to protect against pulling forces. - Desmosomes - Animal.
- 2) Small channels that form across the plasma membranes of adjacent cells; especially important in intercellular communication. - Gap junctions. - Animals.
- 3) Membrane proteins that create watertight seal between cells. - Tight junctions - Animals.
- 4) Small channels between cells that are otherwise surrounded by walls; enable movement of water and solutes between cells. - Plasmodesmata - Plant.
- 5) A polysaccharide that is used to synthesize cell walls, which protect cells and help maintain their shape. - Cellulose - Plant.
- 6) Long fibers of protein found in the extracellular matrix that provide structural support for cells. - Collagen - Animal.
<h3>Features of plant and animal cells</h3>
Animals are known to desmosomes, gap junctions, tight junctions, and collagen to help cells fulfil their duties and keep the body functioning.
Plants have plasmodesmata, and cellulose which ad the plant by helping cells perform their functions.

Answer:Economists have had an enormous impact on trade policy, and they provide a strong rationale for free trade and for removal of trade barriers. Although the objective of a trade agreement is to liberalize trade, the actual provisions are heavily shaped by domestic and international political realities. The world has changed enormously from the time when David Ricardo proposed the law of comparative advantage, and in recent decades economists have modified their theories to account for trade in factors of production, such as capital and labor, the growth of supply chains that today dominate much of world trade, and the success of mercantilist countries in achieving rapid growth.
