Your pupil expands in dim light and contracts in bright light.
The correct answer is B. Hypothalamus.
Explanation
The hypothalamus is a part of the brain that is located below the thalamus, it is an area of the brain where several and very important homeostatic regulatory functions of the organism are integrated. Its main function is to link the autonomic nervous system with the endocrine system. Other functions are to control body temperature, control thirst and urine production (water balance in the body), control food intake, control uterine contractions and milk ejection in mammals, the coordination of the nervous system Autonomous, which affects smooth muscle and cardiac activity, influences behavior and expression of emotions. Therefore, the correct answer is B. Hypothalamus
Answer: Her speed is 4.4 m/s, and her velocity is 0 m/s.
Explanation:
Formulae :

Given: Length of track start to finish= 400 meters
After completing its 4 laps, total distance covered = 400 × 4 = 1600 meters
Time taken by Lila = 6 minutes
= 6 × 60 seconds [There are 60 seconds in 1 minute.]
= 360 seconds
Then, 

But from start to finish displacement = 0 m [displacement is the shortest distance between starting point to the finishing point]
So, 
Hence, Her speed is 4.4 m/s, and her velocity is 0 m/s.
