Answer:
400Joules
Explanation:
the total work done to be calculated is Force× Distance
:f×d=W
80×5=320J
Its has to be A that's just plain common sense
The correct answer is: D) secretin
Gastric secretion is highly regulated whether its secretion should be increased (when food is eaten) or decresed (as the stomach empties). Secretion is controlled by the nervous system and endocrine system that work together. There are three phases of gastric secretory control:
Cephalic-by the brain
Gastric-by the stomach itself
Intestinal- by the small intestine
All of three can work simultaneously.
Secretin is released by duodenal enteroendocrine cells and it stimulates the pancreas and gall bladder, but also suppresss gastric secretion and motility. Secretion of the secretin is stimulated by the chime and it is the part of intestinal phase.
17. The SI unit for force is N.
18. When an Unbalanced force acts upon and object, the object will change speed and/or direction of motion.
19. Average speed is the speed averaged over a span of time. Instantaneous speed would be the speed at any given instance during that span of time.
20. Acceleration= (final velocity - initial velocity) / time
Final velocity= 0 m/s
Initial velocity= 25 m/s
Time = 40 sec.
So, acceleration (0 - 25) m/s / 40 sec.
Acceleration = -0.625 m/s^2
A cell membrane does not actually maintain homeostasis by itself. The term homeostasis refers to maintaining a relatively stable internal environment inside of a multi-cell organism. Since the internal environment is the interstitial fluid that is around each and every cell, then homeostasis has more to do with what is outside of a cell than what is inside of it. :)
