Answer: oxygen, carbon, hydrogen, nitrogen, calcium, phosphorus
Explanation: made up of six elements
Answer:
After a good meal, Jane is relaxing comfortably as her food digests, suggesting her <u>parasympathetic</u> nervous system is in control. When she is frightened by a loud noise, Jane's digestion is inhibited and her heartbeat accelerates, suggesting her<u> sympathetic </u>nervous system is in control.
Explanation:
Parasympathetic nervous system and the sympathetic nervous system are two of the 3 domains of the autonomic nervous system.
During the resting and the relaxing stage,<u> parasympathetic system</u> (also called as rest or digest system) is activated which is associated with the conservation of the energy by :
1) Slowing the heart rate
2) Increasing the intestinal activity ( the reason why Jane is relaxing comfortably as her food digests )
3) Relaxation of the sphincter muscles of the GIT.
While during the fight , flight or fright stage , the <u>sympathetic nervous system</u> is activated which is associated with the body alertness by :
1) Increasing the heart rate
2) Inhibition of secretion of GIT enzymes ( the reason why digestion of JANE is inhibited )
3) Relaxation of the walls and the contraction of the sphincters of the GIT smooth muscle.

Answer: g(x) = 2sin(x)+3</h3>
=============================================
Explanation:
We start with y = sin(x) or f(x) = sin(x). Recall that y = f(x) since both are outputs.
Vertically stretching by a factor of 2 means we multiply each y value by 2.
This means,
y = sin(x)
2y = 2sin(x)
Then we shift 3 units up. So we add 3 to the y coordinate
2y+3 = 2sin(x)+3
---------------------------------------------------
We can track an example point to see this movement in action. For instance, let's focus on the point (pi/6,1/2) which is on f(x). I'm in radian mode.
Stretching f(x) vertically by a factor of 2 means (pi/6,1/2) moves to (pi/6, 1) after the stretching occurs. I multiplied the y coordinate by 2, and kept the x coordinate the same.
Then we shift up 3 units to go from (pi/6, 1) to (pi/6, 4). You add 3 to the y coordinate and keep the x coordinate the same. Note that plugging x = pi/6 into g(x) = 2sin(x)+3 leads to 4.
