The graph above gives the land surface air temperatures and the sea surface water temperatures from 1950 to 2016
Global warming encompasses the changes in climate and temperature around the globe from the oceans to on and
However, when studying the warming of Earth stand and water temperatures a difference between the two can be
observed from the graph, it can be seen along most of the graph that the water temperature of the sea's surface
remained lower than that of the lands surface air temperature. What unique characteristic of water allows for this
phenomenon to occur?
water heat of fusion
waters conductivity of heat
water heat of vaporization
D
water specific heat capacity

Astudent from one of the research labs is having trouble preparing a slide for examination and photographing. the bacterial slide that he has brought to you was prepared using a commercially purchased stain. he has asked for your in determining what he is doing wrong so that he can change the lab protocols and continue on with his project. after examining the slide under oil immersion, you determine that no bacteria are present even though the student is able to show you the culture he used to make that slide that has visible growth in the liquid medium. which of the following statements does not explain the fact that there are no bacteria present on the student’s slide? by not allowing a glass slide to completely air dry before heat fixation, the flame will cause the surrounding water to boil and this will damage the bacterial cell. overheating during the fixation step boiled the water within the bacterial cells and resulted in the cells bursting. insufficient heating of the slide did not drive out the thin layer of water and this resulted in minimal bonding between the bacteria and the glass slide. rinsing with alcohol during the washing step stripped the bacteria off the glass slide. rinsing with alcohol during the washing step stripped the bacteria off the glass slide.
