Using IUPAC nomenclature, give the name of BH3 and AlH3 and elaborate why that name is correct. A) boron trihydride & aluminum trihydride - both molecules combine two non-metals and form covalent bonds.
B) boron hydride & aluminum hydride - both compounds combine a main group metal and a non-metal to form ionic bonds.
C) boron trihydride - boron and hydrogen are both non-metals and form covalent bonds.
aluminum hydride - aluminum is a main group metal and hydrogen is a non-metal and they form ionic bonds.
D) boron hydride - boron is a main group metal and hydrogen is a non-metal and they form ionic bonds.
aluminum trihydride - aluminum and hydrogen are both non-metals and form covalent bonds.

Which of the following statements most accurately describes convergent evolution? the process in which two similar species evolve separately from each other and share similar characteristics the process in which a single species evolves into two or more new species the process in which two entirely different species evolve in response to each other the process in which two different species evolve separately from each other but still share similar characteristics

Which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements. which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements. the framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center. because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane. the diverse proteins found in and attached to membranes perform many important functions. the kinky tails of some proteins keep the membrane fluid by preventing the component molecules from packing solidly together. membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer.
