C) only gap junctions will allow movements of dye from one cell to other cell if dye is injected in to a cell.
Gap junctions are the tube like connections between cell, involve in migration of small molecules between the cell.
While in tight junctions, membrane of cells are attached tightly not allow movements of molecules. These tight junction appear at the places subjected to high stretch.
Similar desmosomes also not allow migration of molecules.
D) based on previous information if dye is added extracellular to animal sheet than only in case of desmosome dye can come to the interior surface of cellular sheet.
As cells are tightly linked in tight junction and in gap junctions would not allow migration of dye from extracellular face to intracellular face.
Only desmosomes allow migration from extracellular to intracellular side.
6. Application: Let's say you injected a dye into a cell. Describe what would happen to...

What are Animals? 1. List and briefly describe the defining features of animals. Be sure you understand these terms: eukaryote, heterotrophic, multicellular 2. Clearly show how the set of features listed in your answer to question 1 distinguishes animals from bacteria, fungi, plants and protists. 3. Describe the characteristics of true multicellularity in animals. Your answer should include: collagen (what is it, what does it do, etc.), gap junctions vs tight junctions, cell differentiation, totipotency and more. 4. To what...
You are asked to determine whether an unknown tissue specimen comes from a plant or an 3. animal. Closer inspection with an electron microscope reveals that the cells are connected by small openings lined by extensions of the cell membrane and containing tubules connecting the endomembrane your observations? systems of adjacent cells. Which of the following conclusions can you draw from a. The openings are plasmodesmata, so the tissue must come from a plant. b. The openings are plasmodesmata, so...

H. = H, = H (6) You are to assume that H , the long-run demand for housing, is equal to the demand for housing you found in part 1. Using this, write out expressions for the two semi-elasticities of long-run house prices in terms of each tax rate. 3. What do your equations for the short- and long-run semi-elasticities say about the reaction of house prices in each period? Briefly describe what is happening. 4. The government wants to...
