I think it’s the digestion
Answer:
They concluded that the cell is eukaryotic cell.
Explanation:
Prokaryotic and eukaryotic cells are the two types of organisms. Prokaryotic organisms are the organisms made up of prokaryotic cells and eukaryotic organisms are made up of eukaryotic cells.
Prokaryotic cells do not have a nucleus and other membrane-bound organelle and eukaryotic cells have a nucleus and other membrane-bound organelles like mitochondria.
Therefore if the cell has mitochondria they must conclude that the cell is eukaryotic because the prokaryotic cell does not have mitochondria as it is a membrane-bound organelle.
The correct answer is b. Head movement → Inner ear receptors → Vestibular nerve → Cerebellum.
The balance and equilibrium of the body is maintained by inner ear in the human beings. The parts of internal ear which takes part in balancing and equilibrium are the semi-circular canals and the vestibule. On the movement of head, the otoliths are pull in the direction of gravity.
C. How the organism is related to others
Explanation:
From a single fossil, a scientist can learn how the organism is related to others. Fossils are the preserved remains of organisms that are usually found in rocks.
- Organisms must posses certain characteristics to ensure their preservation as fossils.
- Most organisms that are preserved usually have hard parts.
- Some climatic influence can also arrest decay and provide a platform organisms to be preserved wholly.
- Fossils are used for relative dating of events in nature.
- They can also be used to determine how an organism is related to another.
- This is called phylogeny. It is the study of evolution and how organisms relates to one another.
- Fossils are very good and useful phylogenetic tools.
