A controlled experiment was conducted to analyze the effects of darkness and boiling on the photosynthetic rate of incubated chl

oroplast suspensions. The dye reduction technique was used. Each chloroplast suspension was mixed with DPIP, an electron acceptor that changes from blue to clear when it is reduced. Each sample was placed individually in a spectrophotometer and the percent transmittance was recorded. The three samples used were prepared as follows.
Sample 1 – chloroplast suspension + DPIP
Sample 2 – chloroplast suspension surrounded by foil wrap to provide a dark environment + DPIP
Sample 3 – chloroplast suspension that has been boiled + DPIP
On the axes provided, construct and label a graph showing the results for the three samples.

Local and global winds are set in motion by air moving in convection cells. Describe the motion of air in a convection cell. Be
IrinaVladis [17]

Answer:

Due to the earth spherical shape, different latitudes of the planet receive varying solar energy levels from the sun. This is due to the differences in how the sun rays hit the earth surfaces and differences in the length of atmosphere the rays have to travel before they reach the earth's surface.

The equatorial regions get the most energy levels from the sun hence their atmosphere gets heated faster and the hottest. The air mass in this latitude, therefore, gets less fast dense  and begins to rise. The cooler and denser air mass from the poles rushes in, through the  lower atmosphere, to replace the void of the rising air.

When this air mass also gets heated, it too begins to rise. Remember the initial air mass cooled as it rose into the upper atmosphere. This now makes it denser than the air mas below it. As the hotter air mass begins to rise from below it pushes the cooler air mass above laterally. After the lateral movement, the air mass begins to sink slowly as it moves towards the poles because the incoming air mass gets denser than the local air mass.

The lateral movement of the convection current moving to the north is deflected to the north-west due to the Coriolis effect of the earth rotation while the lateral movement of the convection current moving south is deflected to the south-west. These pockets of convection currents are called Hadley cells.

Mr. Kline's earth science class set up an experiment to compare the heating and cooling rates of sand and water. They filled cup
Allisa [31]

Answer:

Deserts

Explanation:

Based on the data table, we would expect deserts to have the greatest changes in temperatures during a 24-hour period. There is little water or vegetation containing water in desert areas. The data shows the greatest increase and decrease in temperatures to be in the cups of sand.
