Two students designed an experiment to study the effect of solar radiations on four cities of earth. they used a globe to represent earth and a light bulb to represent the sun. the four cities were labeled a, b, c, and d on the globe at the latitudes shown in the chart below. city latitude a 33° 53' s b 64° 03' n c 39° 56' n d 2° 09' s the students moved the globe slowly around the light bulb in an elliptical orbit. based on the experiment, the students are most likely to conclude that the least variation in seasons will be experienced at city a city b city c city d

50 g of ice at 0°c is dropped in a beaker containing 100 g of water at 0°c. what will be the contents of the beaker after 5 hours? assume that the room temperature is 0°c.

Utah's great salt lake has an average salinity seven times higher than that of the oceans. very few multicellular organisms live in this harsh environment. an example is the brine shrimp, which must devote a large portion of its metabolic energy to osmoregulation. these brine shrimp must available hint(s)utah's great salt lake has an average salinity seven times higher than that of the oceans. very few multicellular organisms live in this harsh environment. an example is the brine shrimp, which must devote a large portion of its metabolic energy to osmoregulation. these brine shrimp must pump water back into their cells to counter its loss due to osmosisactively pump water back out of their cells to counter its inflow due to osmosissynthesize membranes that are impermeable to substances that upset osmotic balanceactively pump salt back out of their cells to counter its inflow due to osmosis
