I'm pretty sure you got them all right. The last one just sounds sort of specific though as Stars are made of Plasma but they don't have heat from the atmosphere. But if you're speaking of only here on Earth then it's correct.
Answer: The hospital incident commander
The hospital incident commander is a medical professional, who is usually the leader of the emergency rescue and response plan in disaster conditions. Such a professional has the authority to rapidly expand hospital capacity, recruiting volunteers, and also ensure the availability of medical supplies in situations of medical emergence in during external disaster conditions.
The right option is; B. 7 major plates and many smaller plates
In the plate tectonics theory, the lithosphere is divided into 7 major plates and many smaller plates.
The plate tectonics theory is a scientific theory that explains that the Earth's lithosphere which is the rigid outer layer of the earth is made up of seven large continental and ocean sized major plates and many minor smaller plates. The movements of the plates are relative to each other and it usually ranges from zero to 100 mm per year. The interactions of the plates along their boundaries are thought to be the primary cause of majority of the earth’s seismic and volcanic activity.
The major species present upon dissolution will be water and N₂O because N₂O is soluble in water.
Explanation:
By "major species," it means, "what type are most of the atoms gift in."
N2O is an ionic compound consisting of N2+ and O- ions. it's gift as molecules within the gas section, however once value-added to water, the ions dissociate (this is true of all robust acids). that the major species gift in answer are H+ (which is typically aforementioned to react with water to make H3O+ or different complexes with water, thus place this if you want).
