Explain why most multicellular organisms use an iron-containing protein for oxygen binding rather than tree Fe^2+ Your answer should include an explanation of (a) the role of home and (b) the role of the protein itself.
Section IlI: Mechanisms (15 points) Providé à complete meca reactions using arrows to indicate the flow of electrons. If asked, use you mechanism to explain the stereochemical or regiochemical outcome. 6. (a) Provide a step wise mechanism for the following reaction (4 points) 2SO4 ) What would you expect to happen if HBr was used instead of H2SO4 in the above reaction?

Explain why for each question. Most high-performance PCs use some type of __ processor(s). A. Pentium B. Celeron C. Xeon and Itanim D. Acceleron and Celerium Less expensive, basic PCs use a brand of Intel Processor(s) called the a. Pentium b. Celeron c. Xeon and Itanium d. Acceleron and Celerium Synchronous DRAM (SDRAM) chips are faster than DRAM chips because they a. transfer data twice for each clock cycle b. are synchronized to the system clock c. do not have...
