Answer:
c
Explanation:
because, it just makes sense
The correct answers are options:
1. Amphibians evolved before land reptiles.
4. Elephants appear in the fossil record after dinosaurs became extinct.
The relative dating is a technique of dating with respect to any past event. In this case, two events are discussed to be occurred in a sequence related to one-another. In the option 1, the amphibians are said to be evolved before reptiles. So, the evolution of the amphibians is relatively dated with the evolution of reptiles. Same in the option 4, the evolution of the elephants is relatively dated with the extinction of the dinosaurs.
The right answer is B.
Nitrogen fixation is done by decomposers that are prokaryotes (bacteria).
<u>Take the example of legumes.
</u>
The different species of rhizobia bacteria, which are able to infect the roots of legumes (Fabaceae family), are specific to certain host plants. Rhizobium phaseoli infects beans (Phaseolus sp).
Bacteria cause the formation of nodules on the roots by penetrating the root hairs, and transform into larger "bacteroids". The nodules are the seat of a symbiotic activity in which the plant provides the sugars and energy from photosynthesis, and in return benefits from the amino acids that are produced there.
