Answer:
A sleepy driver rounds a bend and sees a deer standing in the road. The driver snaps to attention and applies the brakes, averting the accident, because his brain was aroused by the <u> Reticular Activating system(RAS).</u>
<u>Explanation:</u>
- Reticular activating system (RAS) is a part of brain that filters the sensory signal that tries to reach our brain.
- However the olfactory Signal do not pass through it .
- Reticular activating system is located at the brain stem little above the spinal column.
- This is an extremely important part of the brain because it sorts various sensory signals into important and non-important ones.
- RAS allows only those information into the brain that needs immediate attention of the conscious mind.
- Hence it is responsible for sudden wakefulness.
- Our sensory organs perceive thousands of information each second and direct them towards the brain.
- If RAS was not there then our brain would have reached a state of confusion every minute and might have failed to give proper response to any of the stimulus.
- In the given situation, the sudden sight of the deer acted as a threatening stimulus.
- This information needed immediate attention of the driver's conscious mind and his brain was thus aroused by the RAS.
They both help to keep all of the gas and dust in place and not just float off. it evolved from a solar nebula. stars were created in the solar nebula and they would attract gas and dust and became bigger and bigger.

Explanation:
The front of the white paper packet of the OSL dosimeters may be color-coded to facilitate correct usage and placement of the badge on the body of occupationally exposed personnel.
OSL dosimeters are recently developed and are of high quality than thermoluminescent dosimeters. It is used to monitor patients health status. Furthermore, it is very sensitive to any change or drop in reading. it give accurate readings even at 1 mrem for both gamma ray photos and X-rays.
