Depednign on what the cell is trying to transport there could be a variety of ways for the cell to transfer materials.
If the item is small and np then it can go through the lipid bilayer.



Simple diffusion and facilitated diffusion are passive transport meaning the cell does not need energy to transfer the membrane

and active diffision means they need to spend energy.

The disease bullous pemphigoid results in the destruction of proteins within the basement membrane that holds the epidermis and
SVETLANKA909090 [29]
This would directly affect the epidermis because blisters will develop within the surface of the skin. Having blisters on the epidermis will decrease the function of the skin to be an effective barrier to disease. This is because blisters are open wounds that are prone to infection. As infection passes through these openings, it will affect the dermis and the other layers of the skin. Bullae is actually an auto-immune skin disease.

2. study of the similarities and differences in the structures of different species:
= g. comparative anatomy

3. structure that is similar in related organisms because it was inherited from a common ancestor: = c. homologous structure

4. study of the similarities and differences in the embryos of different species: study of the similarities and differences in the embryos of different species = j. comparative embryology

5. scientist who finds and studies fossils to learn about evolution and understand the past:
= i. paleontologist

6. mistaken idea of jean baptiste lamarck that evolution occurs through the inheritance of traits that an organism develops in its own lifetime: = h. inheritance of acquired characteristics

7. process by which a single species evolves into many new species to fill available niches:
= e. adaptive radiation

8. relative ability of an organism to survive and produce fertile offspring: = k. fitness

9. structure that is similar in unrelated organisms because it evolved to do the same job, not because it was inherited from a common ancestor: = f. analogous structure

10. study of how and why plants and animals live where they do: = a. biogeography
