Discussion 1 Biology class
Mitosis provides asexual reproduction in most unicellular eukaryotes. Multicellular eukaryotes become multicellular via this process, and many multicellular species are capable of asexual reproduction, producing "clones" of the parent plant, fungus, or animal. DNA provides the "blueprint" for cellular structure & function.
An interesting "environmental" change occurs during development - identical cells, by virtue of their position in a forming embryo (plant OR animal) & their interactions with neighboring cells become "tissues". Each tissue is specialized for function; while the nucleus contains all the genes of the entire organism, a tissue cell will only express (use) a subset of those genes. For instance, only plant leaves make mesophyll cells that contain abundant chloroplasts for photosynthesis, and only mammalian red blood cells make hemoglobin to carry oxygen. Our bodies are tiny ecosystems, with each type of cell doing its part to enhance our survival!
Thinking of the ecosystem as an organism - what specialized DNA-environment interactions are required to complete a food web? How is asexual reproduction advantageous to productivity & recycling nutrients/raw materials? What other connections do you see?
- a) Several companies use their brand as a competitive advantage. Given your knowledge about the global economy, identify three brands you believe have the strongest likelihood of remaining a source of advantage in the 21st Century and explain why.
- b) Explain the effects you believe the Internet’s capabilities will have on the brands you identified in the previous discussion and what the owner of the brand should do in light of them.
