The 2003 SARS (sudden acute respiratory syndrome) virus was contained to about 8000 cases, mostly in Asia. Which is the best explanation for the prevention of a pandemic?
Infected people in Asia were given massive doses of antibiotics to kill the virus and prevent it from spreading
beyond Asia.
o Travel from Asia to other countries was halted for several weeks to prevent further spread of the virus beyond
Asia.
o Travel from Asia to other countries was increased for several weeks to prevent the spread of the virus beyond
Asia.
o Infected people were given vaccinations to kill the virus and prevent it from spreading beyond Asia

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

i believe the answer would be b. hope it : )
