redesign the device without the solar panel so that it plugs into an electrical outlet
Explanation:
Because of cost implication, the device is redesigned in order to use other source rather than water which would be cost-effective and generally accepted for use.
The telescope I feel like is one of the most important one
Our interconnected neurons help us process different types of information. Synapses are the gaps between neurons. <span>When an impulse reaches the end of one axon, it is now an action potential. This electric signal cannot leap across this gap so as to speak. Special chemicals called neurotransmitters have this role to be possible. The best answer is thus neurotransmitters. </span>

Answer:
Option 2, Arousal
Explanation:
Reticular activating system (RAS) or the ascending arousal system consists of nuclei and tracts and is involved in the regulation of wakefulness, sleep aspects and arousal.
RAS is located in the mesopons and interacts with the basal forebrainand thalamocortical systems. It activates the cerebral cortex and thereby maintain the consiusness. The neurons located at the pontomesencephalic junctionparticipates in this activity of arousal.
Hence, option 2 is correct
