A. oxygen
Explanation:
element in magma is most abundant is oxygen.
Explanation:
Bohr model is able to explain the electromagnetic spectrum produced by different atoms of different elements. This is because an electron around the nucleus of an atom occupies distinct orbital levels around the nucleus and not in between. When an electron absorbs a specific wavelength of electromagnetic spectrum it 'hops' to an upper electron energy level equivalent to this wavelength of radiation. When the atom 'hops' to a lower orbital level it releases ta specific wavelength of radiation that is equivalent to the difference in the energy levels. This was unaccounted for in the Rutherford's planetary model.
The electron cloud model is thought to be an improvement on the Bohr model because it accounts for the Heisenberg Uncertainty Principle which stipulates that it is impossible to ascertain the momentum and location of an electron at the same time (because merely viewing an electron using light -or any kind of radiation - will change its direction and velocity). This model explains the likely position of an electron using probabilistic equations. The electron cloud model can therefore be used to explain bonding between atoms.

Explanation:
a control variable is a variable that remains unchanged of held constant:)
VIII cranial nerve pair has two sensory branches which both pass through the internal acoustic meatus.
A unique somatic afferent nerve is cranial nerve VIII. The vestibular nerve and the cochlear nerve make up its two components. Hearing is made possible by the cochlear portion, while balance and movement are mediated by the vestibular portion.
Both pieces come together to form the vestibulocochlear nerve, which exits the body of the skull through the internal acoustic meatus. Therefore, The auditory vestibular nerve, sometimes referred to as the vestibulocochlear nerve or CN VIII, is a cranial nerve that travels from the inner ear to the brain carrying information about balance and sound.
Therefore, VIII cranial nerve pair has two sensory branches which both pass through the internal acoustic meatus.
