A team of scientists placed five rocks in five separate, artificial environments. All the rocks came from the same formation and had the same chemical composition. The table describes the environment for each rock:

Rock A Rock B Rock C Rock D Rock E
intermittent rain showers
temperatures alternating between -2°C and 20°C
frequent acidic showers that contain carbonic acid covered with algae and lichen placed in an oxygen-rich environment
hot and dry environment
low temperature of 35°C

After the experiment, the scientists observed that one particular rock had large fractures and had split into two pieces. They also observed that, compared to the other rocks, the chemical composition of this particular rock had remained largely unchanged. Which rock most likely fits this description?

A.
Rock A
B.
Rock B
C.
Rock C
D.
Rock D
E.
Rock E

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

explanation:

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
