Charles Darwin's theory that evolution was caused by natural selection explains the sequential nature of groups in the fossil record. The idea that earlier, simpler species have been replaced by later, more complex species explains the diversity of fossils. Darwin's theory of evolution A. is a scientific explanation of the fossil record and modern biodiversity and has been tested by many scientists.

B. is a scientific explanation of the fossil record that has not been tested by many scientists.

C. explains how a new species arose separately after the previous species became extinct.

D. explains how the adaptations of a species do not lead to its survival during periods of change.​

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.

the dorsal column–medial lemniscus pathway (dcml) (also known as the posterior column-medial lemniscus pathway (pcml)) is a sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (position) from the skin and joints.
