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.
The correct answer is - C and D.
The principle of original horizontality means that the rock layers have been order by age, with the layers at the top being the youngest, while the layers at the bottom being the oldest.
In this picture it is little hard to tell which rocks belong to the same layer from first look because there are multiple twists and turns, an uneven surface, caused by pressure on the crust.
By carefully examining the image though, we can trace the layers more properly and see which ones are younger, which older, and which have the same relative age. In this case, we can see that the markings C and D are actually on the same layer of rocks, thus being a good indication that they have the same relative age.
I would say D because mechanical weathering is the breaking up of rocks by physical forces
The teacher should clean the wound
Explanation:
the cut could've gotten something in it
Answer:
Increase
I cant remember the lesson number but if the number of predators increase it would make many animals that are there prey to become scarce in the area the predators are in wich would make many predators starve so in order to avoid they would have to move out across more land to find more food
