Describe a distinctive property of water, how it reflects the internal organization of water molecules, and its importance for understanding biological systems. State whether the H-S bond is polar or nonpolar. Describe the structure as...
Explain the importance of water in biology. What is polarity, hydrogen bonding and how they're important to water? Why are the properties of water important to life? How does the structure of water cause it to have "unique properties"? Why do polar and charged molecules tend to be soluble...
Why is HCl called a polar molecule? Explain your reasoning. Polar Molecules: A molecule is considered polar if it has an overall dipole moment. The dipole moment of the compound depends if the compound has polar bonds and if the geometry of the compound will permit a net dipole moment. Bon...
The intermolecular forces of attraction (IMFA) are the interactions occurring between molecules. These are much weaker than the chemical bonds but are essential in determining the overall property of the compound. For instance, the fact that water has a higher boiling po...
2a), this migration (delocalization) of charge requires a substantial reorientation of water molecules in the solution reaction, with a large associated free energy cost. In the enzymes, on the other hand, the two carboxylates are largely shielded from solvent, and their negative charge is ...
Atoms are the basic units of matter and all life is based on them. Life on earth is based on the element carbon. It is a highly versatile atom able to form four covalent bonds with itself or other atoms such as hydrogen and water. Atoms combine to form molecules and those that are ca...
raikovi pheromones (Bradshaw et al., 1990), provided a good reason to inquire into the pheromone/receptor interactions on the cell surface by studying how native water-borne pheromone molecules associate into crystals (Weiss et al., 1995). This study has for long time remained confined uniquely...
However, prior to the ACLS, carbon dioxide was removed exclusively via a mineral called zeolite, which has pores small enough to trap carbon dioxide molecules in, then flush them into space. Now, Stefano Brandani and Giulio Santori of the University of Edinburgh are exploring ways of using the...

(PhysOrg.com) -- A University of Utah study shows that men hit harder when they stand on two legs than when they are on all fours, and when hitting downward rather than upward, giving tall, upright males a fighting advantage. This may help explain why our ape-likehuman ancestorsbegan wa...
