Answer: The shape of the skull and the supraorbital height tell us the following about each species-
- It can tell us about the intelligence of species and what all senses they were dependent upon for their survival
- Most of the species possess similar skulls as mostly their structures are oval shaped, sloped or round shaped.
- Species have different food habits that is determined by the teeth, which vary from long and dull to short and dull.
- Variation in teeth and face shapes could also be due to different geological locations.
- In particular, the foramen magnum be located where the spine connects can be attributed to how the species gathered food through hunting and what kind of food they sought after.
- Overall, the shape and the supraorbital height of each skull informs us the advantages and disadvantages each species had in its ecosystem.
- It also tells what probable causes of death would be when the species died.
<u>Photosystem I is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by Photosystem I are used to produce the high energy carrier NADPH.</u>
The instrument that records and measures the seismic waves during an earthquake is a seismograph. It uses the vibration propagated by from the earthquake source's energy. It mainly uses a suspended pen that records the motion between itself and the paper film.
