Which statement best describes how the temperature of the ocean's surface water varies
a. areas with a low salinity have the coldest water
b. areas close to the poles have the warmest water
c. areas at high altitude have the coldest water
d. areas with high density have the warmest water

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
