Perceiving pain and assisting in regulating muscle reflexes, breathing, and arousal are all functions of the a. cerebral cortex b. medulla c. reticular formation d. pons

The correct answer is option C,reticular formation

Explanation:

The reticular formation is made of interconnected nuclei that intrude into different segments of brain and the nervous system and thus they are responsible for several functions.  

For example –  

The ascending reticular formation is in touch base with the thalamus and thus it is responsible for sleep related reflexes such as walking in sleep etc. like wise the descending segment of the reticular formation is in touch base with the hypothalamus and thus is related to posture related reflexes and autonomic nervous system activities. The descending reticular control reflexive behavior such as vomiting coughing, swallowing, arousal, breathing etc.  

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
