The homology of animals is based on scientists current understanding on the evolutionary history of living species.
Answer:
E. Nucleus
Explanation:
All living organisms were classified into three major domains viz: Eukarya, Archaea and Bacteria. Eukarya are referred to as EUKARYOTES while the other two domains are collectively referred to as PROKARYOTES.
The major basis of this classification is the presence or absence of a membrane bound NUCLEUS. Eukaryotes are organisms characterized by the possession of a membrane-bound nucleus that houses their genetic material (DNA) while prokaryotes lack a nucleus and hence, their genetic material is found naked in the cytoplasm. Although, prokaryotic cells lack other membrane-bound organnelles like Chloroplast, mitochondria etc. but nucleus is the basis of this classification:
EU meaning TRUE, KARYA meaning NUCLEUS, hence Eukarya means organisms will true nucleus.
In order for plants to assimilate nitrogen directly into their system, the nitrogen must be in the form of nitrates. Nitrogen in the air and ammonia from decayed matter in the soil is converted to ammonium by decomposers and nitrogen-fixing bacteria. The ammonium is further nitrified to nitrates by nitrifying bacteria. Finally, the nitrates can then absorbed by the plants.
Solar Distance:
The solar distance is the distance<span> between the Earth and the Sun. Since the Earth rotates, the distance changes.
</span>
Air Pressure:
The air pressure/atmospheric pressure is <span>the pressure spent by the weight of the atmosphere.
</span>Latitudinal Location:
the latitudinal location is used, with longitude, to specify the exact location<span> of features on the Earth surface.
</span>
Water presence:
The water presence is the existence of water.
There are many factors that influence the weather but the 4 main ones are solar distance, air pressure, latitudinal location, and water presence.
I hope this helps!
