Answer:
The respiratory system transports oxygen from the air we breathe, through a system of tubes, into our lungs and then diffuses it into the bloodstream, whilst carbon dioxide makes the opposite journey.
Explanation:
The cardio-respiratory system works together to get oxygen to the working muscles and remove carbon dioxide from the body.
During exercise the muscles need more oxygen in order to contract and they produce more carbon dioxide as a waste product. To meet this increased demand by the muscles, the following happens:
Breathing depth (tidal volume) and rate increase – this gets more oxygen into the lungs and removes more carbon dioxide out of the lungs.
Graph showing the lung volume in litres of a person during rest and exercise over time.
The graph shows that as a person goes from rest to exercise, their tidal volume increases.
Heart rate increases – this increases the rate that oxygen is transported from the blood to the working muscles and carbon dioxide is transported from the working muscles to the lungs.
Graph showing the heart rate in BPM of a person at rest, during exercise and after exercise.
This graph indicates the following:
the person's resting heart rate is around 60 bpm
at 8 minutes, just before taking part in exercise their heart rate increases – this is called the anticipatory increase in heart rate which occurs when a person starts to think about taking part in exercise
at 10 minutes the person starts to take part in exercise and there is a steep increase in heart rate which reaches 145 bpm at 13 minutes
the heart rate remains high during exercise
when the person stops taking part in exercise the heart rate decreases

Explanation:
I think this is what ur looking for
An important function of cholesterol for the human body is that cholesterol is a source of naturally occurring steroid hormones. Option D is correct.
Cholesterol is a fat-like, waxy material that is present in every cell in the body. The body produces cholesterol to produce hormones, vitamin D, and substances that help digest food.
Its primary function is to protect and regulate cell membrane integrity and to act as a substrate for the production of hormones, hormones, bile salts, and vitamin D.
High-density lipoprotein (HDL) is the “good” cholesterol because it absorbs cholesterol from the walls of the blood vessels and carries it to the liver for waste disposal. LDL, on the other hand, deposits bad fat in the blood vessels.

Part (a)
t = time in seconds
h(t) = height of the rocket
The general projectile equation is
h(t) = -16t^2 + vt + k
where v is the starting or initial velocity (in this case v = 64) and k is the starting height (k = 0 in this case)
Therefore, the equation is h(t) = -16t^2 + 64t
==================================================
Part (b)
See graph below. I recommend using your graphing calculator or some online free tool to get the job done. Doing this by hand would be a pain and it could lead to inaccuracies. I used GeoGebra to make the graph.
To get it done by hand, you basically plug in various t values to find corresponding h(t) values. This leads to generating points in which you draw a parabolic curve through them all.
==================================================
Part (c)
The graph from part (b) shows that the highest point is at (2,64), which is where point B is located.
This means that after t = 2 seconds, the largest height is reached at h(t) = 64 feet.
The rocket then takes another 2 seconds to go from the highest point back down to the ground.
The total time the rocket is in the air is 4 seconds. We could double the value t = 2, or note the distance between A and C on the x axis.
