Answer:
Reticular activating system
Explanation:
The reticular formation refers to the network of neurons formed through the neurons of the brainstem and medulla.
The reticular system is not an anatomical structure but is present in the brainstem of the brain. The reticular formation on the upper side form the reticular activating system and on the lower side has the nerve fibres of the spinal cord.
The reticular system controls the consciousness ad arousals like mood and sleep.
In the given question, the sleep of the professor, therefore, could be due to the slow firing in the reticular formation.
Thus, Reticular activating system is the correct answer.
Reticular formation- brain stem structure associated with sleep, arousal, attention
Answer:
Virus
Explanation:
The study for the pathogen of the tobacco mosaic disease started in 1886 by Adolf Mayer who thought that the pathogen is a small bacteria. Later studies on the Tobacco mosaic disease by other scientists also lead to the same observation.
Beijerinck confirmed that the tobacco mosaic causing disease is not caused by a bacteria but a soluble molecule which proliferates or replicates only when it remains present in the protoplasm of the host cell.
This infectious agent can pass through the filter of 0.1μm pore size that is smaller in size than a bacteria and the can be crystallised. This infectious was called the virus.
Thus, the Virus is the correct answer.

Answer:
I. Unidirectional microphone.
II. Bidirectional microphone.
III. Omnidirectional microphone.
Explanation:
Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.
Sound travels faster through solids than it does through either liquids or gases.
A microphone can be defined as an electrical device used for the conversion of sound energy into an electrical signal or energy.
The various forms of microphone include the following;
I. Unidirectional microphone: picks up sound from a specific direction.
II. Bidirectional microphone: picks up sound from two specific directions
III. Omnidirectional microphone: picks up sound from virtually any direction
